(Clevo P151em) 7970m undervolting

Hi everybody!

I would like to undervolt my 7970m to save power and get its temperature a little lower.
I would prefer a software solution but flashing a different vbios is also possible.

However I don't want to lose any functionality (like enduro or uefi boot)!

I read that with some cards it's not possible to change thw voltage while others claim that it is indeed possible.

I also saw svl7 has a vbios collection for the 7970m, but it seems to be made for Dell notebooks and thus might not be (fully) compatible with my Clevo. (maybe not working after flashing or missing enduro or something else I don't want to happen)


Please, if someone could help me a bit I'd really appreciate it

 

Hello, Msi Afterburner with the .cfg file mod allow undervolt on 7970m but sometimes hang (hard-lock) the OS, beside a vbios flash is more stable.

Look for a software called "VBE7" video bios editor, https://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/
to mod your extracted bios and check alone what is best voltage for your gpu.

 

Thanks for the quick reply, but in the VBE7 thread I read that the edited bios loses uefi functionality, that's why I didn't try it yet....but i might try afterburner and see if it's stable (enaugh).

 

Just modded my vBIOS with VBE7 (undervolted to 0.950v and unlocked overdrive) and everything works perfectly ))

 

So where is my like and my rep??
