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?
