Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:
Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
16 GB DDR4: Cant remember clocks.
1440p 120 Hz screen: No tinkering done to refresh rate.
CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.
My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.
System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.)
I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.
If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.
BAKED BIOS FOR TM, KM, DM, P6, P4 SERIES with most menus and options unlocked.
THESE BIOS MODS ARE ONLY FOR PEOPLE WHO KNOW WHAT THEY ARE DOING!
I'VE BEEN BUSY WITH SOME STUFF PLUS MY SYSTEM HASN'T BEEN WORKING FOR SOME TIME BUT I SHOULD BE ABLE TO CONTINUE MY WORK SOON
I'M CURRENTLY WORKING ON V3.0 WHICH WILL INCLUDE UPDATED UEFI DRIVERS, MICROCODE BIOS SCREEN SHOT SUPPORT AMISCE SUPPORT(For some models) PLUS MORE.
I'M ALSO WORKING ON MODS FOR OTHER MODELS TOO.
ALL TM, KM AND DM SERIES ARE V2.0 AND NOW HAVE WINDOWS FLASHER INSTEAD, JUST EXTRACT AND RUN FLASH.BAT
WARNING! BIOS FLASHING IS RISKY SO MAKE SURE YOU KNOW WHAT YOU'RE DOING BEFORE PROCEEDING.
FLASHING THE WRONG BIOS OR INTERRUPTING THE FLASHING PROCESS WILL BRICK YOUR SYSTEM!

It has been a while since I did anything to my laptop (Clevo P670RG-G) and since I recently got a VR Headset I wish I could overclock my GPU a little. So far the NVidia software (on windows) doesn't allow me to overclock it (the linux sort of allows, which some custom Xorg options) so I decided to give a try modding the vbios.
I read all sorts of issues / guides about it, and it seens that the hardware topology (where the vbios is stored and how things are connected) changes from machine to machine.
What I know about my laptop is that it has two VBios, one for Hybrid Mode and one for Discrete Mode. I'm currently running the discrete mode.
I dumped my VBios using GPU-z and opened up in Maxwell II Bios Tweaker. Everything seens fine so far.
So I have few questions about it:
- There is a way to just unlock the VBios to show the overclocking options in NVidia software? (That way I dont need to reflash to change clocks)
- I can just flash this GPU-z dump to my VBios?
- If I brick my GPU, that GPU-z dumped image is the raw SPI image, so if I managed to physically access the VBios, I can just reflash over it?
- I saw some people saying that I might need as well to flash the main laptop bios as well, is that really needed?
