TONGFANG GK5CN5Z / GK5CN6Z / GK5CQ7Z / GK5CP0Z

Oops my bad, link is now fixed in my previous post.
PS : Hu why not but not now, I almost finished the post and it's not so long (maybe I forgot some stuff). I like the idea of the wiki but I believe there is not enough data (yet at least) for such a thing. I think the forum post, with a link from the first page, is more convenient.
PSS : I know, its already here

To create the bootable USB drive should I simply copy the files in the external memory or it's necessary to use some programs like rufus? What file system should I use?

I'm thinking of updating my pc to latest BIOS and EC from Mechrevo, in case I need it will be possible to switch back to my BIOS for warranty return?

 

Just copy the 3 folders on your usb. You can flash a lower Bios version without problem, but EC can brick your laptop.
For example:
YOU CAN GO FROM:
BIOS XMG 1.03 EC 1.29.09 -> BIOS Mechrevo 1.16 EC 1.33.09 (upgrade BIOS &EC)

BIOS XMG 1.03 EC 1.29.09 -> BIOS Mechrevo 1.16 EC 1.29.09 (upgrade only BIOS)
BIOS XMG 1.03 EC 1.29.09 -> BIOS XMG 1.03 EC 1.33.09 (upgrade only EC)​

BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS XMG 1.03 EC 1.33.09 (downgrade only BIOS)

IT CAN BE DANGEROUS:
BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS XMG 1.03 EC 1.29.09 (downgrade EC&BIOS)
BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS Mechrevo 1.16 EC 1.29.09 (downgrade EC)

For the warranty point PCSpecialist let you flash any bios (ex. mechrevo bios) without ruin warranty, but if you brick the laptop flashing the BIOS the warranty end​

 

@arcticjoe , I would definietly buy one if it match. Where can xe order to test on my GKCN5Z ?

@lKinder_Bueno ,Do you think Mechrevo 1.16 Bios. EC 1.33.09 is compatible on GKCN5Z (1050Ti) ?

 

I have been really happy with the Recoil 2 over the past week. Keeping the fans in Office Mode does limit the CPU to 35W, shown in Intel Tuning Utility, but changing it to Gaming Mode does allow it to reach 45W and sometimes above. I've downloaded the newest version of the Gaming Center software (V 1.2.2.2) and the Low Power CPU mode has been removed but the software is more responsive so it's good for me. I'm still not understanding the fan profile though. Using the basic setting in Office Mode, just the slider, changing the fan speed quickly and if the temps are low enough, will turn them off if the slider is at 0. However, with advanced mode it seems to take an age for the fans to turn off. It also seems that when in Office Mode, if the temperature of either the CPU or GPU, mostly the CPU, goes above 80, the fans will go to near max volume and then go back down to whatever you set it on, the cycle keep on repeating. I guess there is an automatic override at 80 degrees to prevent the laptop from overheating but anything under 90 degrees on the CPU seems safe so it would be cool to be able to turn that automatic override off.

As for the rest of the laptop, the screen is amazing. I got the 144Hz model and I haven't had any issues with it. The keyboard is nice to type on, once you get used to the layout, and is a bit clickly but it definitely isn't as loud of desktop mechanical keyboards (comparing it to the Razer blackwidow tournament edition). Trackpad is good, although I have been using a mouse for 95% of the time. Having ports on the back makes my desk look a lot tidier. The speakers are meh, good enough for watching some videos. The seem to be loud enough, I have them on 30 volume whilst watching YouTube and its a good enough to hear everything.

As for battery life, I havent properly tested it but Windows does say 3 hours when I unplug it at 100%. I guess its about what is expected for a 46Whr battery and 144Hz screen. I did get the 180W power adapter from PC Specialist, it is a Chicony 180W, Model: A15-180P1A. It looks similar to the one I had with my GS63vr before returning it, I cannot confirm that though.

Other than the slight 'issue' with the fan control, if you want a laptop thats similar to the Aero 15/Razer Blade 15/MSI GS65 thats cheaper and you can deal with the low battery life, I'd say go for this!

 

Thanks @lKinder_Bueno for all this useful stuff I'll put in the recap post I'm making when I will be less busy.
I think you did a mistake, the PCS Bios link goes to an XMG BIOS !

I have further questions about BIOS/EC update :
- is it safe to combine a BIOS with an EC from a different reseller and/or a different time ? No possible incompatibility ?
- Baidu instruction to update BIOS/EC with "auto easy" method says you have to update bios before EC which is the opposite of manual EFI installation instructions. Is there any reason for this ?
- If I want to create my own EFI bootable USB stick, do I just need to copy the EFI folder with always the same files, and BIOS and EC folders with related AfuEfix64, .nsh and .ROM ?

 

I've just installed the newest BIOS and EC from Mechrevo without issues but i have a couple of questions:
-What is the OTP level, I've read you talking about it previously but never understood what it is and never interested a lot until now because was not present in my previous BIOS version. Default is set to low.
-I've also installed the 1.2.2.2 version of gaming center with customized logos. I noticed that default it keeps the fans in office mode every time I start the computer, any way to change it? I prefer to have fans always in gaming mode as I had with the previous version of GC from eluktronics.
-Also noticed that keeping the computer in gaming mode every time i restart the computer it changes my CPU power limit 1 and 2 seen in HWiNFO both to 35W. To have it back to default (respectively 55 and 65W) I have to select another mode than back to gaming mode.
Seems that this version of gaming center does't allow to keep the computer default in gaming mode for both fans mode and TDP level. Any way to change it or I have to switch back to the older GC? Version 1.2.2.2 seems lighter and more responsive...

 

- OTP means how much voltage cpu will receive.
High OTP means high voltage, cpu can reach higher performance, higher temperature and the cpu will go in Thermal throttling easier.
On 1.10 Bios i Always used OTP at low (and on not mechrevo bios it is set by default at LOW).

- The 1.2.2.2 Version is for the 17" Version. I think for this reason Low Cpu Voltage is "removed" and you can't change the Fans Speed in Office Mode.
DL Mechrevo Version: http://driver.tongfangpc.com/d.mechrevo.com/driver/GamingCenter_1.2.2.2_Mechrevo.zip

Yes, i pasted the same link for XMG and PCS bios. Now i have fixed the urls.

- Yes it is safe to mix OEM Bios. XMG, PCS, Origin ecc ecc just buy stocks from TongFang and they are the same Laptops. OEMs just add their own logo to the case the bios. T he Motherboard & Bios are from Tongfang and they are pretty the same.

So you may ask why XMG 1.03 bios runs better than PCS 1.04 Bios. The answer is because they just use different way to add number version to the bios. Just rember a Bios that cames with a higher EC version is surely most updated than a bios with a lower one.

- I just used the instructions that PCS sent to me for flashing the 1.04 Bios. I trust much more PCS than Mechrevo. I have also to say that everywhere for every laptop is Always suggested to flash before EC and then Bios.

- Yes. And when you will flash instead of write f.nsh you will have to write the .nsh file name.​

 

Hi everybody. I am a habitual reader of this thread but although now I had no registered, thanks to everyone for so much information available...

So, my question is: anyone knows if there is any option to buy an entire keyboard replacement? I have a Recoil II from PCS and some of my key switches are broken because an accident and PCS tells me that they only send keys as replacement, no the keyboard so I am looking for any other seller who can sell me the entire keyboard. Any idea? I asked Illegear about their new "brown switch" option and I am waiting for the response...

 

@lKinder_Bueno Do you have a link to PCS Bios ? I have ordered mine on a Frech site names pcw.fr and I would like to update Bios/EC.

Also, where can I have instructions to flash EC and Bios ?

I have done this but the USB Boot doesn't launch anything when I click on it.

 

Thanks for the explanation, I’ve switched back to the previous gaming center I had because fits better my needs.

About the bios is there any possibility to change the boot logo? It’s not an important thing, just aesthetic, but I don’t like the mechrevo’s booting logo so much.

 

Which Bios does Eluktronics use?

 

The brown keyboard is so much better than the default blues. With the blue the keys were shaky and sometimes inputs are registered even without pressing to the point where the blue click triggers, but now I no longer have any of those issues. Overall quality and feel is a huge improvement and feedback is solid. Also I no longer have to be paranoid about my heavy typing when in public.

 

This improved keyboard will be available also for the 15'' model?

 

@Caas How did you get it ?

 

Where did you bought the keyboard?

 

I asked Eluktronics about brown switches for their Mech 15 G2. They are shipping this month and should be in for them starting November. Dunno if that's the same for other US side builders or not.

 

My reseller just acquired it, there was a three weeks wait for the first batch of brown mechanical keyboards and I got mine slightly early as someone high up there is my friend.

 

Would it be possible to order throught you or your friends ? What is your laptop with brow keyboard ?

 

Hello ! I'm considering buying version of this laptop with GF1060, can someone tell me how does it present along with other laptops with GF1060? I mean for example with Acer Helio 300 or Asus Scar II.

 

This review is one of the best showing the capabilities of this notebook.
https://www.notebookcheck.net/Schen...-GTX-1060-Full-HD-Laptop-Review.315660.0.html
Hope you find some answers.

 

Neat nice to see the teardown and review.

Looking to be quite the capable streaming portable too. Nice.

Also its good to know it comes loaded with thermal pads stock.

Will be sure to finally get one once the brown switches come in domestically.

 

Hi guys, I'm interested in the GK5CN6Z, I plan to buy it at https://laptopparts4less.frl/15.6in...1060-6Gb-Coffee-Lake-game-laptop-samenstellen is it a good reseller ? (to be honest the name looks a bit weird to me).
About the display, is the 60hz one good ? I've watched the Bob of all trades video and it seems the 144hz display is great but if the 60hz is alright, i'll go for that.
Also I read the last few pages of the topic and it seems it's better to get the 180w power brick instead of the 150w ?

thank you

 

Hi I'm interested in buying a mechrevo laptop. But not sure which one, either the Z2 or the x8ti. They basically have the same stats but the x8ti has the gaming look and is thicker. I wonder if the cooling is better on that thicker laptop. And how the fan noise and display is compared on both laptops.

 

The 144Hz is an awesome display, the same in Razer Blade. I have the 60Hz version, it is a good display, better than some Asus i tested, but it hasn't the WOW effect you can have from the 144Hz version.
If the upgrade to the 180W is free, go for the 180W. With the latest bios version the 180W is not so necessary.

Maybe i replied you on YouTube, but I read the x8Ti Thermal are similar to the Z2, they have the same motherboard and cooling system. PCSpecialist version sell it with a low quality display, so check the display model before purchasing it. I don't know if fans are less "noiser", but if i have to choose between x8Ti and Clevo N850EK1, i would choose the clevo one​

How update Bios and tune laptop with XTU. Idk if someone need it, but here is the video

 

Hey, I got mine from there, no problems, very pleased with the purchase and the price was great. I got the 60hz panel, and it has the panel discussed here (BOE0747 NV156FHM-N61) and not the crappy one that pops up in other variants. I have been playing Far Cry 3 on it and there are no problems with ghosting. Color reproduction and brightness are also really nice - I normally work on a MBP with a pretty glorious screen and I have no problems moving over to the TongFang.

Now that I've set up everything nicely, I really, really like the machine.

 

OK I read a review about it and they said the Z2 is annoyingly loud https://www.notebookcheck.net/Tongfang-GK5CN6Z-i7-8750H-GTX-1060-FHD-Laptop-Review.331426.0.html

 

Read this review:
https://www.notebookcheck.net/Schen...-Tongfang-GK5CN6Z-Laptop-Review.315660.0.html

Nobody is complaining about fans noise here

 

I read this review, they complain about it. And In witcher it's 52db

 

[ANNOUCEMENT - 4th of december, 2019] Most parts of this guide were written when only the GTX versions of GK5CN and GK7CN laptops existed. Now that this thread also covers more recent GK5CQ7Z and GK5CP0Z, and that there is a dedicated thread for the 17" versions, some information in this post may not be relevant for your laptop. Please just read carefully

Also, HERE IS A LINK TO THE WHOLE MEGA FOLDER CONTAINING MOST FILES (bios and utilities) LINKED BELOW - for backup purpose.
---------------

Hi, I tried to compile here every useful information I found about GK5CN laptops. Many thanks for the work accomplished by people on this forum and elsewhere ! I hope you can find answers for most questions about GK5CN here.
I'll try to keep this post up to date as much as I can by watching this thread and others.
Please tell if you find missing or irrelevant information, as well as missing download links (especially GK5CN5Z BIOS and EC).

@sicily428 could you please link this post into the first one of the topic ? Copy-paste in the first post might be better but I could not update it...

/!\ BE CAREFUL /!\
None of the methods, software or tips explained here is absolutely safe. Be sure of what you do, and do it at your own risks !

######## Reviews and resellers are listed here
######## Videos about GK5CN are aggregated here (more reviews, teardowns, ingame tests, keyboard and fan noise tests, tutorials...) and there (especially performance tweaks, tests and explanations, by @B0B )

######## Keyboard
There is two kinds of keyboard for these laptops. The "classic", clicky, "blue switch" one, and the silent "brown switch" one. Blue switches is known to be very clicky and causes sometimes multiple actuation. Thanks to @lKinder_Bueno for his videos
- Keyboard chattering fix - Against undesired multiple actuation, set the value to 100-150ms. Info found here
- Video : DIY silent brown switch mod (semi-destructive way) + sound comparison
- Video : DIY silent mod (very destructive way)
- Some proper options exists (see next links), but are not publicly available yet
- Exetrnal topic : Illegear (Malaysia) sells blue (clicky) and brown (silent) switches with 2 different caps layers, for the moment only to their clients.
- PCS sells a 17.3" GK5CN (Recoil II) which seems to have the exact same keyboard as the 15.6", but with silent switches and sober layout. Replacement keyboards with brown switches will come soon !
- XMG also sells the laptop with the sober keyboard layout (but still clicky switches)
- Still waiting for a way to get the silent keyboard for people who buy their laptop to resellers that do not offer it...

There seems to be several versions of each kind of switch:

######## Battery
A bigger battery can be installed at the cost of the 2.5"" disk emplacement, increasing autonomy of about 40 to 60%
- Link to bigger battery - worldwide shop (Hong Kong)
- Link to bigger battery - european shop
- Another store selling it (Germany)
- Eluktroniks (DE) also sells it to anyone
- Successful mods from small to big battery on GK5CN6Z by @david04 here and by @99-0 there

######## Miscelanious parts
- Stickers / Skin : (good if you want to hide ugly branding) Ebay link, - pictures of one from AliExpress - more pictures here
- Back plate / Bottom cover replacement part: here on Taobao
- Screws kit: here (Micro Center) and there (Amazon)
- Charger / AC Adapter: several solutions (angle or straight connector, 180W or more, sizes...): see this post from @ezradharma
-You can find in the image below part number of most spare parts of this laptop. Comes from this page.

Spoiler: SPare parts numbers

######## Noisy fans
Fans can be normally or abnormally noisy. You can see this video (done by @lKinder_Bueno ) to get an idea of what should be a "normal" noise.
If you think that your fans are abnormally noisy, you maybe have :
- Turbo fan mode turned on : turn it off into the Fans settings tab of the Gaming Center (switch in the upper right corner), or via the dedicated fan button next to the power button of your laptop
- Gaming fan mode turned on into the Fans settings tab of the Gaming Center. This mode can be a little bit noisy. If you don't need a lot of power, switch to way quieter Office mode. Keep in mind that it sets CPU power limits at 35W instead of 55 and 65 in Gaming mode.
- a mechanical issue that can be solved by opening your computer and carefully disassemble and check the fans. Also, have a look at "Fixing the hardware issues" rubric.
- a laptop running too hot, because of dirty fans, badly thermal pasted CPU and/or GPU, or weird performance settings.

######## BIOS + EC
BE CAREFUL
Flashing BIOS and/or EC can be tricky for inexperienced users and can brick your laptop, especially if you want to downgrade EC (flash EC with a lower version than yours) !
For example:
YOU CAN GO FROM:
BIOS XMG 1.03 EC 1.29.09 -> BIOS Mechrevo 1.16 EC 1.33.09 (upgrade BIOS &EC)
BIOS XMG 1.03 EC 1.29.09 -> BIOS Mechrevo 1.16 EC 1.29.09 (upgrade only BIOS)
BIOS XMG 1.03 EC 1.29.09 -> BIOS XMG 1.03 EC 1.33.09 (upgrade only EC)
BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS XMG 1.03 EC 1.33.09 (downgrade only BIOS)
IT CAN BE DANGEROUS:
BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS XMG 1.03 EC 1.29.09 (downgrade EC&BIOS)
BIOS Mechrevo 1.16 EC 1.33.09 -> BIOS Mechrevo 1.16 EC 1.29.09 (downgrade EC)

For the warranty point PCSpecialist let you flash any bios (ex. mechrevo bios) without ruin warranty, but if you brick the laptop flashing the BIOS the warranty end

HOW TO FLASH YOUR BIOS/EC ?
There is two main methods.
- Easy but risky: using automatic batch installer.This method is depreciated: you might brick your laptop. To proceed, first close all apps, unplung every external device, except power adapter, then run F.bat and follow instructions.

- Tricky but safer: EFI boot an USB stick and install from here. See instructions below :

EFI boot installation instructions:

DOWNLOAD LINKS
(Downloads are classified from most recent to older EC versions, as resellers might use different BIOS versioning. So for example BIOS 1.03 from XMG is not necessarily older than 1.04 from PCS)

For GK5CN:
- BIOS 1.09 - EC 1.38.09 - XMG - Download link (BIOS auto batch, EC need to be used in addition with EFI boot)
- BIOS 1.09 - EC 1.37.09 - XMG
- BIOS 1.05 - EC 1.35.09 - OverPowered - GK5CN6Z / OP-LP2 ( Auto batch)
- BIOS 1.02 - EC 1.33.09 - OverPowered - GK5CN5Z only (auto batch - no EC upgrade !)
- BIOS 1.00 - EC 1.33.09 - OverPowered - GK5CN5Z only ( auto batch - no EC upgrade !)
- BIOS 1.16 - EC 1.33.09 - Mechrevo - GK5CN6Z ( EFI boot install or Auto batch)
- BIOS 1.03 - EC 1.29.29 - XMG - GK5CN6Z (EFI) - Apparently the most power saving
- BIOS 1.04 - EC 1.25 - PCSpecialist - GK5CN6Z (EFI)
- BIOS 1.06 - EC 1.24.09 - Illegear - GK5CN6Z ( EFI boot or auto batch) and GK5CN5Z (EFI boot or auto batch)

For GK5CP0Z:
- BIOS N153 and EC - EFI boot install
- BIOS N151 and EC - EFI boot install
- BIOS N102 and EC - EFI boot install

HOW TO UNLOCK THE BIOS ?
Yes, BIOS provided by manufacturer or assemblors are "locked". Fortunately, Lost_N_bios made us a guide on win-raid forum, explaining how to unlock tons of features ( some might brick your laptop, you have to know what you do by going this way). Thanks to @nimaim for his work on this and his annoucement post here that you have to read before starting:

######## Gaming Center / Control Center / Alternatives
(from most recent to older ones)

Gaming Center U -
- 1.0.0.17 from Eluktronics

"Gaming Center 2 - made for RTX Tongfang models but seems to work with 1050Ti and 1060 versions. Updated and darker interface than the v1 serie with some little improvements. According to @stesteste : Selecting Game mode doesn't automatically change the keyboard lightning layout, screen settings and lock windows key, there is a dedicated button to do it. LED light bar settings issues are solved so you can change settings for both "plugged in" and "on battery" while being always plugged in or on battery. Game Mode for fan settings is now hidden, you have to activate turbo mode then it will appear and you can select it. Seems quicker and more responsive. Performance are really good: on CB15 I registered an average of 1270 with a peack of 1278 in respect to 1250 scores with Mechrevo's GC 2.0.1.1 with same configuration and settings)
- 2.0.1.3 - from Eluktronics - not branded and modded with no animation
- 2.0.1.1 - from Mechrevo - branded

"Gaming Center 1 - made for GK5CN5Z and 6Z"
- 1.2.3.4 - from Mechrevo - modded with classic icones, no animation, no welcome splash with music, and english as default lang.
- 1.2.2.8 (from OverPowered (compatble with Windows 10 1809) - modded with classic tray icone and no animation)
- 1.2.2.2 (from Mechrevo - branded)
- 1.2.2.1
- 1.2.1.6 (from BTO - branded)
- 1.1.16.4
- 1.1.16.1 (from Mechrevo -branded)
- 1.1.15.12 (from XMG) - no xtu service - Modded installer with regular skin and no animation
- 1.1.15.3 (from PCS) - no xtu service

How to disable animations ?
There is two ways. One applies before installation, the other can be done after installation (depreciated)
Before installation (best way) :
- Find setup.ini in the unzipped archive you got from the download
- Open setup.ini with a text editor
- Locate the two lines beginning by "Animation" and "ShowAnimation" and modify them as following:
Animation = 0x00
ShowAnimation = 0
- Save and close the file then run the installer
If you didn't followed these steps before installing Gaming center, you can still disable animations by modifying the registry so way is depreciated.
- Open the registry editor (push Win Key and type "regedit")
- Go the following path: \HKEY_LOCAL_MACHINE\SOFTWARE\OEM\GamingCenter\Animation
- Edit Animation entry by double clicking on it, set the value to 0, then press OK.
- This will be effective on next reboot

How to change Gaming center's appearance ?
Some GK5CN sellers provide customized versions of the Gaming Center with a branded skin.
You can find proper images in a clean version of the Gaming Center, as well as you can create your own if you want \o/
Simply replace image files found in logo folder situated:
- Before installation: in the archive you downloaded
- After installation : C:/Program Files/OEM/GamingCenter/logo
- New images have to keep the same name, extension and dimension as the ones they replace
- Most of the time you only have to replace img-edm.png as well as some .ico

Is there any alternative to Gaming Center ?
There now two ! The most exciting one is called Rev.Center, developped by @lKinder_Bueno especially for us and source code is available on github. Last version is 1.65 (27th february 2019) and download is available here. More details on this post:

The second one is called MyApp, a kind of simplified Control Center made by TongFang for previous chassis but still GK5CN compatible.We don't exactly know how it interacts with Control Center, which still has features MyApp dont have. See this post and following pages. It seems to cause troubles with some anti-cheat securities from some games.
Download link:
- MyApp 1.6.1.0
- MyApp 1.6.0.0
- MyApp 1.4.11

Okay thanks but I'm looking for something lightweight to CONTROL THE FANS ONLY. What should I use ?
@lKinder_Bueno also developed Fan Control, available here :

WHAT IF I WANT TO USE THE MEDIA KEYS WITHOUT THE Fn KEY ?
@ditchmagnet did a pretty good work/script/tutorial here about how to do this.


######## Drivers links
- OverPowered support page : OP-LP1 stands for the GK5CN5Z and OP-LP2 for the GKCN6Z
- Mechrevo support drivers download page: Hoover the links on the right side and check the file's name to know what you're going to download
- Eluktronics support drivers download page
- CyberPowerPC driver page and BIOS page (look for NB-408-111 as GK5CN6Z or NB-408-110 as GK5CN5Z)

######## Fixing some hardware issues
Some issues (erratic on/off and behavior) regarding the keyboard, its backlights, and fans have been fixed by carefully checking mobo connections to these components and/or wiring management, as some wires might be jammed by a screw.
Some touchpad erratic behaviors have been fixed by applying a bit of pressure on the touchpad part that face to the battery (behind the battery).

How to get better / louder audio ?

How to get better screen refresh rate ?
It is possible to increase a little bit refresh rate of the screen. Instructions in this link. @lKinder_Bueno went from 60 to 64Hz, and some other went from 144Hz to 156Hz on another laptop that use the same 144Hz panel.

Working touchpad in Linux
Solutions to get the touchpad working under Linux have been found here.
- For a Linux distro with 4.15 Kernel : download patches located here and run them. You may need to re-apply a few of them (especially linux-image-unsigned-4.15.0-34-generic.deb) after a system update.
- For a Linux distro with other kernel : more info and source can be found on original page
or in the following tutorial:


######## How to get a working Linux
Just look at this post (working touchpad and Optimus, Linux Mint 19.1 with 4.15 or 4.19 kernels)
There is also an "unofficial control center" made to control keyboards RGB lighting that you can find here on Github. (Thanks @LeoniePhiline to point this out).

That's possible too, but you wont be able to use the dedicated Nvidia GPU. Wifi and Bluetooth also need to be replaced to work. A working EFI folder can be found here. Clover and some kexts are outdated now, but it should still work. Simply install using this EFI folder then update everything. If you're not familiar with hackintoshing, have a look at this subreddit.

Know problems
Some people noticed processor performance issues (low clock rate, power limits stuck at 35W, Thermal throttleling...), resulting in a Cinebench score under 1000, FPS drops...
Concerning v1.2.2.2 (might be the same - or not - for older versions) : it appears that the Gaming Center (or Control Center as logically called by XMG) is changing CPU power limits depending on the FAN mode :
- Gaming mode : PL1=55W and PL2=65W
- Office mode : PL1=PL2=35W
Performance modes changes minimum and maximum CPU speed as and Windows power plans (known as My******* in Windows Power Option configuration panel).
As far as we know:
- Game and High Performance modes set CPU speed to full speed (between 3.8 and 4.1GHz)
- Equilibrium Mode : variable CPU speed (up to 4.1GHz theoretically)
- Power Saving Mode sets maximum CPU speed at 2.2GHz
- Single RAM channel can become a bottleneck on some CPU intensive games ( see this video for explanations)

Tips to solve CPU power/performance issues, in order of troubleshooting :
- Plug your AC adapter in !
- In Gaming Center, switch to Gaming mode in the fans settings, and to Equilibrium mode in the the System Monitor tab. Performance modes "High performance" and "Game mode" just constantly max out CPU frequency, which is useless and seems to give worst perfs, as i7 8750H and i5 8300H are made to fastly change frequency by themselve.
- Update to last BIOS, EC and Gaming center versions. So far (january 2019) the combination of most recent versions of BIOS (1.05 from OverPowered), EC (1.35.09) and Gaming Center (1.2.2.8) seems to be a solid choice. See above ######## BIOS + EC part for download links and instructions.
- Obviously, check for drivers and Windows updates
- Give a try to OEMSev, as some laptops might be sent with a firmware power limitation that doesnt fit the used AC adapter. Furthermore, a BIOS/EC update can reset this setting, so you might need to use OEMSev again after BIOS/EC update, especially if you have GK5CN6Z with 180W power adapter. Instructions below.
- Try to undervolt CPU core and cache offsets of around 125mV with Throttlestop. You should notice slightly lower temps and better perfs. A 2017 Throttlestop guide is available here while the thread with download links and a lot of useful information is there. Information about undervolting under Linux can be found here. A tutorial video specifically made for GK5CN laptops by @B0B is available here !
- 35W limitation when in Office fan mode (as well as default 55 and 65 PL1 and PL2) can be overriden in ThrottleStop by toggling "Disable and Lock Turbo Power Limits" into FIVR window, then set proper values in TPL window (such as 60 for Turbo Boost Long Power Max and 70 for the Short Power Max).
- Go dual channel RAM ! Best is to buy 2 exact same sticks, but differents might also work.
- It doesn't have to be necessary but it helps anyway: replace stock thermal paste under CPU and GPU heatsinks with higher grade and thick thermal paste. Conductonaut is best but very tricky to use as it is liquid metal (can easily break yout laptop). Kryonaut and Noctua NT-H1 are not good choices (even if they're good for desktop PC) because they're too thin and pump out easily. Gelid GC Extreme or DC Diamond are good. Just in case, here are picture and details about thermal pads, if you want to replace them as well. @ditchmagnet got better results by adding a foil under screws of the heatsink in order to get more pressure and it seems to work.It seem to avoid big temp differences between cores (might also hapen because of a thin paste pumped out).

Found on this forum by @steberg LINK TO FILE (for GK5CN5Z and GK5CN6Z)

Furthermore, a BIOS/EC update can reset this setting, so you might need to use OEMSev again after BIOS/EC update, especially if you have GK5CN6Z with 180W power adapter.

/!\ Benefits and risks of this tweak are still uncertain /!\
What to do :
- Download the file and open the correct folder regarding your laptop version
- Open F.bat with a text editor
- Find the following line : OemServiceWinApp.exe AdpType /Set #
- Depending on your AC adapter, replace the # at the end by : 1 (?W adapter, maybe 230W?), 2 (180W adapter), 3 (150W adapter), 4 (120W adapter)
- Save the file and run it as administrator
- Reboot and you're done

######## Battery life / Unpluged performance
As this laptop is, well, a laptop, a lot of people expect from it to get correct lifetime when unpluged. Here are a few tips:
- Maybe you will need softer undervolting settings when your laptop is unpluged if you want to avoid crashes. You can do it in Throttlestop by setting a battery profile and specifing it in the Option window (toggle "Battery profile" and set the number of your battery profile. If you use high TPL values for when your laptop is pluged in, you might limit current drain when on battery by decreasing CPU core IccMax values (and maybe also PP0 ?) in FIVR window for the battery profile.
- Several users experienced excessive power drain from the deditaced graphic card running even when not needed. It seems to lead to a PKG power of ~12W when idle, which is undesired. To avoid this, make sure you didnt force your internet browser to use your dGPU. If you use MSI Afterburner, make sure that "Apply overcock at system startup" is NOT toggled, as it automatically turns the dGPU on just to apply your OC/UV settings, even if you dont need it. Also, @arcticjoe made a script that turns off the dGPU when the laptop is unplugged, forcing any app back onto iGPU (unless the dGPU is needed, ie for external monitor use):

how does the GK5CN6Z compared to the GK5CN67 in performance and cooling and noise?
I have difficulty deciding between them

 

Hard to say only GK5CN67 review I've been able to see on notebookcheck is in German.

GK5CN67
https://www.notebookcheck.com/Test-Medion-Erazer-X6805-i7-8750H-GTX-1060-FHD-Laptop.333268.0.html

GK5CN6Z
https://www.notebookcheck.net/Schen...-Tongfang-GK5CN6Z-Laptop-Review.315660.0.html

It looks like the GK5CN67 is somewhat cooler maybe as I don't know the pastes used as its all in german and there fan are a couple of decibels quieter though again my caveat on not knowing the thermal solutions used.

What it does seem is that the GK5CN67 is much more prone to trapping heat in the case looking at the thermal camera images. Probably because of its use of ventilation slits instead of the more open wire mesh screened bottom of the GK5CN6Z models.

Take a look over the reviews yourself. they both have the same structure so even if there is a language barrier you can still get the jist of it from the categories.

 

OK I compared. The data. BTW I'm German.
The thicker laptop is about 6db quiter under different loads and it's about 10c° cooler. Performance wise they both get about 38 and 39 fps in the Witcher 3. Thick laptop 1fps more.
To sum it up the thin laptop is noisier and hotter.
Unfortunately the review only shows the 60hz display version.
I don't know how much ms the 144hz version has on the thicker laptop. I can't find it out.

I found something out.
I found this picture in a Chinese review and they seem to have the exact measurements.

Again no data about response time

https://m.baidu.com/talon/c/s/m.zol.com.cn/miparticle/6849392.html

So what shall I do if I can't find out the response time of the GK5CN67? The noise level in the review of the GK5CN6Z is disturbingly high.
I find the noise level scary of the review u it.

Forget it I went to the store today again, and the keyboard is way louder than I thought. It's impossible to use in the library

 

Yea the brown switch options are coming next month.

 

What brown switches?

U mean I should wait ?

 

There will be an option to have Cherry MX Brown switches coming to the 1060model (not sure about 1050ti). Cherry MX Brown switches are basically identical to Blue's (the ones that are currently on the laptop) however, they do not make the audible 'click' but do contain the tactile feeling when pressed.
If want the laptop but dislike the clickiness of the keyboard, I suggest waiting for the model with the Cherry MX Brown Switches

 

Just to clarify, the switches on this laptop are not made by Cherry to my knowledge. They are a mechanical key switch in a Cherry MX Blue style, but not Cherry made.

Also worth noting, we are planning on introducing the Quiet (MX Brown type) keys for the 15.6" Recoil II once existing stock has sold through, so the next month or so by my estimation. These switches are standard on the 17.3" variant.

 

Are the modded keys as quiet as real brown switches ?

 

Nice to read that. As a customer of the Recoil II with clicky keyboard (french azerty, laptop bought about a month ago), will I be able to buy a new quiet french keyboard as replacement ?


Do you know which key layout will the quiet keyboard be sold with ? I mean between the actual one with white edges on arrows, W, A, S and D, or a sober one ?

 

I want x8ti plus by mechrevo. It has clicky sounds so I guess it still had the blue switches.
Is that right?
And how high is the response time of the screen?

 

Hey Jacob,
Can you confirm whether the keyboard in 17.3" model fits the 15.6" model? Asking not just because of the brown switches, but the keycaps look better as well on that one - I find the 15.6" ones too flat, so when I touch type its harder to feel the placement of your fingers without looking.

 

I asked to buy the 15 inch keyboard and they told me the keyboard is builtin in the case, so they can't sell it. I think it is a lie because if you go on fortunetechnology (their shop for resellers) they sell the keyboard as single part.
I suppose it will end as the display upgrade, they will say something like it doesn't fit or gtfo

 

Furthermore you can buy replacement keyboards. I asked if you can buy individual switches and or caps, and they answered me than you can only buy the full keyboard with switches+caps. So why not making the quiet keyboard available this sway ?

 

But they told to me they were only caps :/
The final price is also very low. It is just ~35€

 

To ask could you buy the concave key caps that XMG uses?

 

The technical support guy told me (sorry for the bad translation) : "If you order a french keyboard to replace your old one, you will receive a brand new keyboard, including caps and switches".

I think he means that you get a keyboard case with switches and caps already mounted on, so you would just have to replace your whole keyboard case by the new one

Maybe one of us has to tear down his/her own laptop in order to see if the full keyboard case can actually be fully and easily removed (without removing glue, bending some parts, destroying some other...)
I bet that removing the whole keyboard is easier and less dangerous than just removing a single switch

Not on PCSpecialist yet. But we have hope :
- 17.3" Recoil II seems to use the same keyboard (still looking for confirmation) but with QUIET switches, and caps with a new layer I never saw before
- We know that PCS will have quiet keyboards for 15.6" Recoil II very soon. Maybe it gonna be with the concave key caps XMG and Illegear uses
