Official Coffee Lake Thread/BIOS For ALL SkyLake/KabyLake Clevo LGA1151 laptops

@DaMafiaGamer Please give us your thougths on this compability issue on 75xDMx

 

Sorry I only got a notification now lol. For some reason this thread was unwatched.

I think dsanke did mention about incompatibility issues with the 751DMx series.

I also had problems in the beginning with my p870dmg, I encountered a black screen. Gop was fine, it turned out the ram I was using was not compatible with the new bios. I don't know how it made a difference but it did.

I changed my 4x8gb sticks of hyperx ram with 1x16gb of crucial ram and after 2 automatic boots the screen lit up.

Also those two pins on the cpu HAVE TO BE COVERED unless you want burnt eradicated pins on your socket

I will pm dsanke and ask for more info on this incompatibilty fiasco.

 

Do I also have to cover the pins in case I keep the i7-6700k in it?

 

No

 

No, the pin coverage is to convert the newer chips to appear like the older ones.

 

So, for completeness, here's what the BIOS screen tells me :

MB series : P7xxDM29-G)
BIOS : 1.05.01TOPC
KBC/EC : 1.05.02

ME FW : 11.8.55.3510

TOPC presumably stands for Origin PC. I'm reluctant to gamble too much since Origin PC won't support me and it seems that the EC would not be easily recovered in case of a misfire with the update.

 

There were some problems with the model P7xxDMx that have been fixed in the course of time (key combinations, microcode, panel etc..).

Have YOU tried EC 1.06.01?

 

@radolf : not yet. I'm uncertain whether the newer EC would happily work with the existing older BIOS. I'm also concerned because the schematic suggests the chip involved with the EC on this model has many pins. A failed update (or an incompatible update) would leave me with a dead machine (I'm not set up to recover such a chip).

Imagine the grief that could be avoided if vendors supported the machine rather than just the first owner....

 

I already flashed the Secon EC on my laptop, it's a P870DMG, but with your P751DMg2 it's no different!!! My programmer supports this chip. That would be the main problem to have a programmer that supports everything!
I can also offer you to flash against a compensation!

 

As I understand, there is one SOIC8 IC for both EC firmwares and another SOIC8 for BIOS in Z170 clevo models?

 

Yes, it's an 8-PIN chip again!? So programming device on and ready!
Z170/270/370 it's all the same!

 

So, can I run the newer EC (1.06) with the older BIOS (1.05)? That's something I'm uncertain about.

 

Just try it out! I don't think there are any serious differences between the ECs of the same model, would be strange! One makes anyway a backup of the Rom(EC) or downloads the appropriate Rom(EC)!

 

I am not going to risk breaking the machine at this point in time; I cannot recover the many-pin EC (per the schematic) easily. When the BIOS updated failed, the machine was down for over a week waiting for the programmer to turn up (and the clip for the 8 pin EEPROM) - I had a clear recovery plan (still needed some guidance, it turned out, but I knew the machine wasn't unrecoverable). In contrast, the EC chip looks to be much larger and more complicated (presumably requiring desoldering). That's more than I want to deal with at this point in time - the machine is in active use on a daily basis.

 

The Main EC is controlled via the BIOS chip (SPI=GD25B64) and the Second EC via a separate SPI chip (SPI=GD25D10) which I already mentioned! If YOU have a proper programming device, then you don't need to solder!
Of course I can understand your concerns.
The version 1.06.01 is of course for your model. If the Second-EC doesn't work either, take your backup and play it on it again!

 

It's really not simple to recover the EC.

 

Off-topic. but I must stress how disappointing it is that Origin (and seemingly most vendors) just wash their hands of all support when a machine changes hands. The machine I have was effectively brand new, but the previous owner had changed their mind about it. Changing ownership didn't remove the money paid to Origin from their pockets and didn't instantly cause the machine to burst into flames or result in any warranty or support demands. At this point in time, all I really want is a BIOS/EC update that is expected to work on this hardware - they simply won't make that available (at any price, it seems). It's infuriating on a number of levels - I'm happy to pay a reasonable sum, but can't get anywhere with them or anyone else that ships similar hardware.

 

Can I use this BIOS while using a 7700K at 4.2Ghz(stock)? Because Coffee Lake mod bios will decrease the 7700K stock clock at 3.4Ghz.

P870DM2_DM3 notebook

 

If it has a Sager S/N we can provide firmware.

 

Does this mod replace my Prema BIOS or does it just make it so that i can run the new CPU? Also can i uninstall Intel management updates or am i out of luck since Ive been updating everything with Obsidian driver tool?

 

This is a BIOS flash, so it will overwrite whatever you currently have. You can still update IME (and any other drivers) manually, the Obsidian tool is just a one-stop shop to simplify things.

 

Have you gone through HID to see if they an get you a file?

 

They just sent me a message saying 7700k officially and then unofficially pointed me here.

 

For gaming I would tweak your CPU as it is and use the vbios editor which will work on your current vbios. Do you have something in particular that needs more CPU?

 

I’ve recently got a 3D scanner and the models I’m doing are starting to bog down my cad programs.

 

Then you will need to loose the prema options and flash this if you want to upgrade.

 

Is this a stock bios with just the mod to allow the newer cpu’s? What kind of options will i lose from the Prema bios?. I’m kind of on the fence of trying this mod or just buying a new system.

 

It will be stock iirc so you will loose all of the prema options. The stock bios still let's you adjust cou voltages, multipliers and memory speed.

 

I want replace my 7700K to a 8700K because I think it'll enhance speed in Rpcsx3 and Cemu emulators and to gain more fps(~10) in PC games in general. I think P870DM3 heatsync wouldn't enough to cool a 9900K CPU even at stock speeds without a heavy downclocking and undervoltage.

Getting a dellid tool for 8700K soon.

 

Ok guys I successfully upgrade my P870DM3-G 6700K to a 8700K no problem... I just dont try to upgrade to a 9900K because I'm afraid of temperature constrains. I'm not keen to install a watercooler or something in it
Btw its a hell of difference in 3Dmark physics and overall scores... did I miss much not installing 9th Intel gen processor?

 

Btw testing in XTU I noticed some current throttling... how can I correctly configure XTU to gain more stability and maintain high performance?
@MrClippy can you help me to set right values in XTU for 8700K? Shall I use ThrottleStop program?

 

How do you guys able to recover the P750DM-G bios? I got a skypro usb programmer and a CH341A. But both unable to detect the bios chip. I flash the bios few weeks ago and ended up with no boot now.

 

Hi friend. Can you help me please? I buy the CPU -8700 not K version for my P870KM modded, and my GPUs 1070 not started. I dont have any compability video card for flashing right bios. One of choice i have - desolder smd chip, flash, and solder back. My problem - i dont have dump vbios with right GOP version, can i flash with programmer as is topic vbios or i need full dump right bios? Thanks

 

Put your old CPU back(6700K?) into the notebook and see if it works again, if it works flash the right modded bios for your laptop version and if its all ok then replace for your 8700 CPU.

 

just installed an i5-8400 on my W650KK1 very successfully and enjoying the performance the 6 core 3.8GHz monster is giving me.
I succeeded in undervolting to -160mV and everything is stable with 3.8GHz all cores while stressing. The performance boost is also noticeable in games. no more lagging to 40fps, just stable 60fps now.
Thanks @dsanke great job!

 

I install 6600k back and nothing change - gtx1070s not start 0 black screen, quadro m1000m starting in both changes CPU. i can not flash vbios with quadro because it is damage after 20-30 sec - white screen. GPU (m1000m) is overheating in another notebook. problem in my 1070 - wont starting screen...

 

hi. please help find vbios GTX1080 clevo 86.04.56.00.2D

 

So i succeeded in updating the bios but for the life of me I cannot figure out how to do the pin mod section on a 7700k. Any advice?

Edit: Maybe I did not succeed in updating the bios. I took the SSD out and it still won't boot. Not sure if it is because I don't know how to do the pin mod or the bios install failed.

 

7700K does not require a pin mod. Only 8th gen (i7-8xxx) and 9th gen (ix-9xxx) CPUs going into boards/laptops with Z170 or Z270 chipset

 

Okay, so that means the bios update did not take and my system is bricked, correct?

 

It will just have a blackscreen on boot and shut itself off after a few minutes whether the 6700k or 7700k is installed.

 

any help in flashing the bios chip? i need help in flashing the chip using the skypro SPI programmer.

 

Hi, are you able to help reprogram my motherboard too? i am in Poland.

 

Same here. I'm having a hard time just finding my bios chip

 

What machine do you have?

 

P870DM/Sager NP9870

 

The BIOS most likely is under the keyboard but since my model is different: P775DM3-G maybe wait until someone with a similar model comes along. @Mr Fox can you help?

 

I checked under the keyboard and didn't see anything that looked like a bios chip. I'm hoping to get some input before I just decide to tear the thing apart. Still don't know how to use the skypro programmer.

 

For example in P775DM3-G the BIOS chip is this one.

It's in the far left of the motherboard under the keyboard (you need to tear down the whole laptop)

 

Sounds like it, unless you missed something simple like not clearing/resetting NVRAM/BIOS settings or neglecting to check and update GPU VBIOS GOP/UEFI version first

Look for an 8 leg black rom chip like the winbond chip in the above pic ^^^ but instead labelled "U12" on the P870DM - it's almost directly underneath the top right corner of the touchpad - which means you have to disassemble to the point you can remove the upper case (~30 screws and a bunch of connectors and ribbon cables worth of fun)

Look on youtube for how-tos for your programmer, the main source of frustrating problems is the connector not getting good contact with each leg of the chip. If you haven't used it before it can be really tough to troubleshoot no connection or no data read: bad clip contact vs the clip is upside down vs the BIOS chip is not supported vs the BIOS chip is bad vs the SPI bus preventing on-chip programming ...
