Yep, but I have gone from a different approach, I did it by largely increase the tREFI because I have met the barrier on other timings

The errors brought by tREFI is only a sign of freezing while using, so it's going to need time to verify.

Unlike the sign of errors brought by tRFC, which is no boot or BSOD, or return error.

By the way, I finally had 1 error at tRFC = 664 while running TestMem5, so I increased it to 674.

I am going to give it about 2 weeks to see if this is the optimal timings for my machine at 3467MHz.

 

Now you need to run testmem86 and then some gaming.

 

Yep! I've just hunted a few Nergigante with my favorite bow set in Monster Hunter World, no problem so far, Memtest86 scheduled for tonight

Thanks for all the help, rep and likes! @Johnksss @Papusan @Falkentyne @raz8020 @hmscott

Edit:

I'm currently working aboard and I've just found that I left my bootable USB stick at home.
I'll just test it with everyday usage until I get back home around mid Oct for the Memtest86.

 

Anybody knows what is happening here?
Sometimes when I leave my laptop ON, when I'm sleeping or something - I'm waking up to this picture on my external monitor:

That's MSI logo on my desktop which is repeated 16 times.
When I open laptop - its display is not turning on at all (normally it does).
Only power button helps. It goes to sleep and wakes up normally with both displays working properly.
(external display is 4k via DisplayPort, internal is 1080p 120hz).

 

I had that happen too even without external screen plugged in. I was scared for a second it was the gpu dying... but in my case I simply had to turn off the display timeout feature in advanced power settings in windows. Then I could leave it alone at all times (bad thing: not good for your screen to be always on so I ended up only using the external screen which has its own timeout setting). Anyway you can try out whether this issue applies to you as well by setting the timeout for 1 minute and then seeing how it behaves when the screen is supposed to go to sleep repeatedly. That's how I determined that was the issue. Otherwise I would start updating/reinstalling drivers (especially graphics drivers - or rolling back if it only occurred after updating recently).

 

It seems to happen when display is turning off, but most of the times it's ok, but sometimes it goes like this (maybe 1 out of 10).
It happens on all drivers that I tried. And only via display port. HDMI has another glitch.

Did you have that on DP or HDMI?

 

Mmm for me it also happened with no external screen attached, then I had mini screens which looked like artefacts on the internal screen. Or it failed to turn on. But it actually only happened on 390.xx drivers mostly. 391.xx drivers gave me BSOD's when the display timed out sometimes and 398.xx drivers (I believe) gave me some black screens on boot. I just entirely gave up on the feature where the display times out. Also, manually turning off my internal screen with the fn function resulted in the same issues sometimes. Sorry I don't have a solution for you. Do you use DDU when installing new drivers? Does this also happen on 391.xx drivers (as I didn't have this on that driver, only occassional BSOD).

Almost any store you walk into should have a usb flash drive. (Key word "almost")

 

Well I wish the transportation here was easier, I'll see what I can do this weekend

It's been up since Tuesday morning.

With the laptop half of the time on battery for office work and browsing, and half of the time on plugged-in for some gaming and multimedia stuff when I get back to my room.

So far no freezing nor BSOD.

The last time I pressed reset button in HWINFO64 was 58 hours ago

 

Deleted *edit* doesn't work.
The Nvidia GPU has to be physically *removed* for the iGPU to work.
The Embedded Controller register F1 (or the option MSI GPU Mode) on the GT73VR and GT75VR actually electrically disconnects the PEG port, so when you boot with the iGPU, the PEG port reports that nothing is installed, or status is "Not installed" even if the Nvidia GPU is installed.

Disabling the PEG port in the Bios still keeps the hardware trying to *output* to the disabled PEG port (e.g. the Nvidia card is still actually detected).

I don't know if switching electrical outputs to the iGPU as the rendering device is possible without physically removing the dGPU.

 

Hi, guys

its been a while because I've been sick. I bought a UHD optical drive I'm told for UHD playback that I need to use the Intel graphics how can I switch from my Nvidia 1080 to Intel graphics for 4k viewing? also, it shows Intel SGX* is also missing but I know the 8950hk supports it along with Intel 630 UHD graphics. I'm running my MSI gt75 8rg with a USB 3.0 connected LG Electronics Blu-ray/DVD Writer Optical Drive - WH16NS60 firmware ver 1.0 and a Samsung U28E590D 28-Inch 4k UHD LED-Lit Monitor connected via an HDMI 4k cable running Cyberlink PowerDVD 18 ultra. What else must I do to enable UHD Blu ray and UHD file playback?

Thanks,

Bionicfreeze

 

No one knows how to do it.
The only 100% way to USE the iGPU in windows is to physically remove the Nvidia GPU.

You can easily enable the iGPU by setting "Integrated Graphics" from "Auto" to enabled, and if the dGPU is enabled, the iGPU will also appear in device manager, but windows won't be able to render to it and the Intel drivers won't be able to access it (it's addressable in Linux, however).

The problem is, there is no way to SET the iGPU as the primary render device. It will always be set to the PEG port.
Physically removing the Nvidia GPU will cause the device in peg port 0:1:0 to show up as "not installed", forcing the iGPU to be active.
However if you disable the PEG port through the Bios, this does NOT disable the system detecting that a device is inserted in the PEG port, which means it will still attempt to display output to the port, causing a black screen (forcing a bios CMOS reset--60 button power button depress).

There are options in your Bios to set the primary display.
You can try this but don't expect it to work.

there may be more than one setting for primary display.

Try the following:

Go to System agent and:Graphics configuration and:

1) set Integrated Graphics to "Enabled" and reboot to windows. If this shows the iGPU as available but nothing can use it, go to step 2.
2) go to Peg root port 1 and DISABLE the peg port.

then go to system agent ->Graphics configuration and try messing with changing the "primary graphics" to "iGFX" for each option.
Then reboot the system.
If you get a black screen you will need to Clear the CMOS by : hold the power button down for 60 seconds, then release it and wait 3 minutes for the MSI logo to appear.

You can also try setting it to "SG" (Switchable graphics) instead of iGFX.
But be prepared to do some CMOS resets if it doesn't work.

IF THIS DOES NOT WORK (clear cmos), you MUST disassemble the mainboard and pop the CMOS battery. However this clear cmos trick has been tested to work in all of the "GT" Titan laptops (GT83VR, GT73VR, GT75VR).

It may not be possible to force the system to render to the iGPU as the primary display device. If it uses a multiplexer there may be no way to address it. If the iGPU works with the nvidia GPU physically removed from the system, there may not be code in the Bios to force the iGPU to be the target device if the dGPU is actually plugged in.

 

Why the heck would you want the Intel SGX (Intel Software Guards Extension)? That is only needed for software developers who want to incorporate a specific security feature into the apps they develop and is not needed for the casual or even power user/gamer.

Intel SGX when enabled (which is the default setting by the way) causes some erratic behavior like mouse stuttering for wireless mice according to my experience and needs its own driver.

I guess HIDevolution knows about this nuisance and disable it from the factory.

If you still insist on having it, let me know and I can help you.

 

This probably wasn't even a feature fully tested by MSI so it can be buggy/problematic.

 

Which post were you replying to, Kevin?

Gotta quote so we know.

The GT73VR and GT75VR doesn't even show the "primary display" options in System Agent when you do the 4 key combo. Everything between "Skip scanning of external gfx card" and "gfx card primary display configuration" in AMIBCP 5.02 is simply not there.

Yet it is there in the GS65 and GT63 and GT75. (coffee lake).

I'm going to see if manually unlocking those options makes them appear. It takes hours to set all options everywhere to supervisor. And I'm scared of something going wrong with a menu option (that doesn't normally appear with the combo) and then a brick. I do have an 8192K full bios backup that I did before my last GPU LM repaste, but I would have to remove the GPU to take a HW programmer to that and I have no idea if the system would work afterwards.

I did figure out why you get a black screen when you disable PEG port 1 on the GT73VR when Integrated Graphics is set to enabled.
@hackness

In AMI Graphics output policy, if the Nvidia card is inserted, you see some Nvidia thing at the top with "DP0" for the option and no way to change it to anything else.
If MSI GPU Mode is set to iGPU (or if you toggle EC RAM register F1 to "01" in RWEverything and reboot--it seems that this EC option is set by the bios instantly---if you set MSI GPU mode to iGPU in the bios then go to "EXIT AND DISCARD CHANGES", it changes the GPU anyway, while all other things you changed get reverted back (if anything)), then under AMI Graphics output policy, you see "Intel GOP driver" and Intel something else, with the selection "EDP1". No option for DP0 anywhere.

In Peg root port 1, it shows as "Not Installed", meaning the EC (or something else) completely disconnected the PEG port totally, as if the NVGPU were physically removed.

There doesn't seem to be a way to disconnect the PEG port and then switch the display to EDP1 without having a black screen. If you set PEG port 1 to disabled, you get a black screen since obviously its still outputting to DP0. But if you remove the Nvidia card, then there is no electrical connection to PEG port 1 so the iGPU gets the output.

I'd still like to know if "MSI GPU Mode" is setting one of those "Primary display" options or if those options just cause an instant black screen and the EC is simply disconnecting all input to the PEG port (not the same as disabling PEG port 1).

 

according to both LG and pioneer its required for UHD Blu ray disc playback also who do both LG and pioneer insist on using Intel intergraded graphics 630 or above when my Nvidia 1080 card is more than adequate to enable 4k disc playback without even breaking a sweat?

 

All the credits goes to @hackness for the help.

For some reason, CR value at 1 give me a black screen so i stay with 2.

Next step is going to ratio 13

 

I have a question for everyone All of the UHD Blu ray drives say they require intel 630 graphics or better, however, if you like a lot of us have a Nvidia 10x based card would that not be equal to not greater than the Intel 630. I'd assume my Nvidia 1080 in my MSI gt75 8rg is far more superior than an Intel 630 also msi claims one button on the right side of my keyboard is to switch your active gpu any thoughts?

 

Next thing to do is 3466 and maybe get another stick of RAM

 

Well, i cant get futher because im getting black screens with ratio 13...the best atm is 3200MHz

@Ultra Male bro i get today my second 970 evo 1tb and i create a backup from my single 970 evo.
after installing the second 970 evo i was able to restore the backup on my raid 0 without issues(it was needed to add the driver to the usb recovery rescue configurator and that thing is now only for my GT75VR).
maybe paragon backup&recovery is an good solution for you if you are still without an backup solution.

 

You mean you used Paragon Backup & Recovery to do this? I stopped using Macrium as it has failed me a few times

 

100% yes.

 

Here are the pictures from creating the device.
sorry it is in german but my translation should help out if not feel free to ask.
after starting the backup & recovery from Paragon:

 

i create an backup before and start from the usb device after creating the raid 0. the winpe environment find directly the 860 evo and the raid 0 with my both 970 evo. revocery takes about 60min. i was playing with my little daughter so it could take less or more. what can happen is that you get an bsod but i fixed this with an safty mode boot in windows 10 and after this everything is working. i guess that windows 10 had an driver issue but i don't know why.

 

Can anyone help me how to overclock my MSI GT Series GT75 TITAN-058

 

So Newegg has the previous version of the GT75 (with 7820) on sale at an attractive price. Is that still worth getting or am I better off with the new 8th gen processor. I am assuming the thermal management is the same on both models. I will mainly be using it for gaming. Btw: how is MSI customer/tech support?

 

Thermal management is not the same. The gt75vr (older one you are looking at) has better thermals both for the cpu and mainly for the gpu (as with 8th gen the cpu runs so hot they stole a heatpipe from the gpu to help cool it, nevertheless it still runs very very hot due to the extra cores and extra frequency).
Anyway the gt75vr is a good one. The 7820hk is a very good cpu and can be overclocked well and should never let you down in games. If you also want to stream and stuff, yeah the new 8th gen cpu will do a much better job with that. But is it worth the price difference? That depends on your needs and what you think is important.
MSI support will differ based on country. Sharing where you are from will help others give a good answer. Here in the netherlands, the call support is very friendly and if stuff goes wrong with a repair they have a local technician helping with more insight. I liked that as the repair center in Poland did a poor job (reinstall windows and push a VBIOS that limits gpu and pray the customer doesnt notice). The local technician agreed with me that was no good and I got a nice upgrade out of it. I am happy to have sold the laptop now and run a pc, aside from coil whine from my gpu (which is being looked into) the pc is better in all aspects. So if you dont need a laptop per se, I would reconsider. MSI also has a great assortiment of motherboards, gpus etc. And they seem ok.

 

It would be perfect for all your gaming needs. I had the previous GT73VR Titan Pro then upgraded to the new 8th Gen CPU GT75 Titan, other than in benchmarks, believe me I don't notice a single difference.

I would get it from HIDevolution if I were you to get a perfect build quality and more importantly to get their thermal cooling mods like Thermal Grizzly Conductonaut + Fujipoly Thermal Pads + Bottom Panel Mod

To be fair the decisions for things like that comes from MSI HQ in Taiwan and is not an single technician decision.

On the other hand me and some other team members of the german msi forum had the possibiltiy to visit the repair center in poland and it was really interesting to see how and what the technicians do and with this knowledge they have my deepest respect.
But i was not able to grab some stuff like heatsinks and so on . the plan was to sent some stuff to @Falkentyne.. sorry bro i had not the chance .

The best thing of all were the bga repair stations and they show us how they repair broken chips with removing and add an new one on the motherboards.

 

Thanks guys for the responses on the GT75VR. BTW: I am in the US. So any input on US MSI service? For warranty work, if I need to send the laptop back to MSI, will they pay for return shipping?

 

MSI support is very good in the USA, and shipping is paid both ways. If you buy from HIDevolution, you will also get our Tech Support and Warranty Service that wraps around the MSI Warranty.

 

Thanks Donald!

 

can anyone tell me how can i remove the key cap for this keyboard for cleaning?, is it same as other keyboards?

 

So I finaly got to try out the GT75 in a store as I don't live in a big city but were on a visit today. And as @Ultra Male has said numerous times the keyboard is by far the best laptop keyboard I've typed on. Long story short they had the GT75VR Titan (7RF-046NE) with the 7820HK in a display case for demo purpose and I got it for 2.400 USD or 20.000 NOK, they would not sell me it first but I think I got a sweet deal since the 8RG costs 4.800 USD here with the same SSD/HDD and RAM specs. I happily gave up 2 cores for that price... When I'm home in a couple of days I will set it up and move my 970 evo drives + order 32GB of extra RAM.

 

Congrats on your purchase. Please share with us on your experience after using it for awhile.

 

Originally, the GT75 was on my short list as an upgrade option for my ASUS G750JZ-XS72. I started hedging after watching some YouTube reviews claiming the KB was REALLY LOUD. I haven't had the ability to type on one in person, and I haven't seen many negative noise reviews on this forum, so I was wondering what the general feedback is concerning the keyboard noise?

 

The keyboard is not quiet. It has a distinct click not unlike a Cherry MX Blue. I have no complaints about the noise but I still use a Model M on my desktop so that should put context to my tolerance. It could see it bothering others sensitive to noise in a quiet environment but I don't personally consider it an issue.

 

Thanks for the feedback!

 

I got lucky and got the 4x8GB setup lol. With the unlocked bios does the GT75 support xmp profile? The price differences between 2400, 2666 and 3200 is minimal and I was thinking about getting 64GB of the g.skill 3200mhz ram.

Unlocked BIOS will allow support of XMP profiles, however not all speeds are supported.

 

Thanks brother! Anyone tried with 3200mhz? I see the 8RG supports it, but that's one generation newer...

Oh and the machine is absolutely perfect so far. I've had it for a week now and haven't opened it yet. Can't seem to get it over 75 degrees Celsius on CPU or GPU with gaming or rendering work, and the fans are quiet. I will start benching and overclock this weekend...

In HWinfo, what is the value to show max power value of cpu?

That one that trigger the PL1/PL2 limits?

 

Cpu Package Power

 

Ok, im asking this because playing the assassin's creed odyssey im seeing some values above 45w on my 8750H but the cpu never goes less than 3,9Ghz.

@Papusan can you explain to me how really works this PL limits and what i can expect if those goes above 45w for a long time?

Thanks.

 

PL1 is the long time power limit and usually set to the CPU SKU (see 45W for H BGA chips). PL2 is usually the short time limit (PL2) and set to 1.25x. But as it is now the notebook manufacturers is more free to put PL2 limits. Dell for example put 78w for the first 30 seconds and then 56 watts. With very high load over time (more like 256 sec) it can drop to the CPU SKU's TDP 45w.

 

Acer predator helios 500 have now a feature that allow change the PL limits in the sense program.





Normal - Stock TDP (45 & 56)

High - Long boost at 45w / Short boost at 70w

Max - Long boost at 56w / Short boost at 70w

This is the beast. Feel free to comment and recommend alternatives.

I have thought long and hard about which processor to take and I hesitated a lot between the i7-8850H and the i9-8950HK and I have chosen the former because it only requires one adapter instead of 2, is cheaper, and possibly is a bit cooler. I have not found evidence this processor is throttling so far.

However I would like to ask you if it can be tweaked further to reduce the temperature like the i9 can. I have seen (a massive amount of) very detailed posts about tweaking the Bios and getting better temps, from @Ultra Male (Phoenix) and @Falkentyne and from what I understood the stock settings are not optimal and should be changed. Will the Bios of the i7-8850H allow that ?

I am looking forward your advice and comments.

And if I'm posting in the wrong thread I apologize.

 

That is a decent CPU and is cheaper and runs cooler. Don't forget to choose the Thermal Grizzly Conductonaut + Fujipoly Pads and also ask them about the bottom panel mod when ordering.
