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?
In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
For creating bios backup and to flash bios mod, you must use any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip!
Just dump your Bios using any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
