As of a few hours ago, it appears that the custom air RTX3080 heatsink for P775TM1 is no longer available - only the air/water version is now available: https://www.aliexpress.com/i/1005007688521117.html Well, it was overpriced anyway. I am waiting for a RTX3080 to arrive within the following days, so I am exploring alternative options. Are there any measurements-detailed instructions on how to modify the current 31-P77FN-401 heatsink (i.e. by drilling)? Any other options for heatsink mounting? How bad is it if I do not use any screws on the GPU side? If anyone knows of a modified 31-P77FN-401 heatsink that is compatible with RTX3080 and is available for sale within the EU please keep me informed.

It's a pity that I do not need the entire chassis, but only the modified heatsink for a RTX3080 I recently ordered (I want to avoid the Chinese ones). If you would be interested in selling the heatsink only, please let me know, as I am based in the EU.

@dude-137 Based on my personal experience: Using "Balanced" Windows Power Profile when idle - clock set to 3.60 GHz the temp fluctuates around 60 degrees. "High Performance" profile will lead to a gradual overheating of the PCH up to ~80 degrees - clock at 4.68 GHz. CPU core voltage offset around -72 millivolts. In my opinion, the voltage of the power rails of the PCH should be measured. I have never modified the cooling system at all and still I am far from 100 degrees (also many VMs are running synchronously).
-
@dude-137 A 100+ degrees Celsius PCH temp is definitely not normal and not a design flaw on Clevo's part. The max I have got with regard to PCH temps is 80 degrees Celsius. I would suspect an electrical problem (overvoltage maybe?).

Clevo P751TM1 BIOS flashing help, Thunderbolt without display
harkaz replied to Gualdo's topic in Sager & Clevo
P775/P750 are compatible as they use the same motherboard. P870 uses a different board so most likely not compatible. The vendor who sold me the laptop got the file for me from a supplier. -
Try with 'High Performance' power profile while on battery to see if system resumes ok. If the problem exists only on AC power, the PSU, the power socket, or even a cable could be implicated.
-
Cleaning the board using isopropyl alcohol may help. Also, use compressed air to remove any dust particles from the CPU socket.

Try installing the latest chipset drivers: https://www.intel.com/content/www/us/en/download/19347/chipset-inf-utility.html Another suggestion would be integrating the latest microcode for the new 10900k CPU to your BIOS. If all software/firmware options fail, consider a hardware issue (CPU or mobo).

Good to know you got it sorted.

The GPU firmware (its UEFI component) must be whitelisted in Secure Boot if the Microsoft UEFI CA 2011 has been removed/blacklisted from secure boot database. You may be able to revert to BIOS defaults without monitor: Try hitting the F2 repeatedly at startup (this will launch BIOS setup with a black screen). If you have specified a password to access BIOS, type it and press ENTER. Press F3 and press either right or left arrow once (should select 'yes' in a pop-up about loading optimized BIOS defaults). Press ENTER. Press F4 and press ENTER.

Have you tried Windows Compatibility Mode? Is HyperV enabled? (this causes problem with Intel XTU)

EC is fine, the system would not boot without it. Probably the BIOS is not clean in terms of Management engine and you need to flash the clean 8 MB BIOS from palkeo.com repo. You can also find the EC there. Link: https://repo.palkeo.com/clevo-mirror/P7xxDM23G/ (Username/password: repo/repo). Tip: Game with fans at 100% speed. I use this to extend the lifetime of my device (I use headphones while gaming). Press FN+1 to force this and the same key combo again to force normal fan speeds. Also, thermal pads may need replacement. Board may be defective if keyboard/touchpad are not working.

@DLoa Try every seller you can find and hurry, the item will soon be unavailable everywhere. Order 2-3 of them and test them expect ~ 1/3 defective. Remember to remove the protective films from the ribbon cable and stick to the back of the keyboard. rtdparts: ordered 2, 1/2 with a defect (F6 key extremely sensitive). Seller informed it is out of stock.

If your model is P751TM (not P751TM1): https://repo.palkeo.com/clevo-mirror/P7xxTMxG/P7xxTM(G)_B10729.zip If your model is P751TM1: https://repo.palkeo.com/clevo-mirror/P7xxTMxG/P7xxTM1(G)_B10729.zip EC seems ok. There are 2 EC chips, as a matter of fact. If EC did not function at all, keyboard lights would not come up at all. You can also test the Fn+1 key combination - as long as EC is functional it should make fans spin at 100% even without a CPU! From posts online, I suspect the PCH is malfunctioning (probably after thermal damage). This is a guess. Not the most likely explanation if this happened after power failure. NOTE: The SPI flash you refer to is used for automatic flashing of the EC. However, if EC is malfunctioning, low-level programming tools have to be used (i.e. https://ioprogrammer.com/).

Always use protective cover for these keyboards. Also, the ribbon cable is very sensitive to bending.
