Radeon HD8970M stuck at 450/300mhz

[msigx]

Hello.

I have a problem here. I installed Radeon HD8970M, and it worked out-of-the-box in MSI GX740, but now I have problem, with 3D clocks.

Under stress it didn't want to go full 950/1250, and I have done everything that I can do in Windows (Afterburner, Clockblocker, Maximize performance in Powerplay).

I think it's a problem with vbios, that my laptop can't read quite properly. I want to edit those close, which are at 450/300, but VBE7 doesn't let me do it, and the voltage is there locked too.

So I thought that hex editior would do the job, but still - I don't know where to edit it (which lines), and how change voltage (from 0.9V to 1.0-1.05V).

 

I have attached my original HD8970M Vbios dumped with GPU-Z.

Thanks in advance!

Ok, I changed with vbios, thanks to @Khenglish, with 650/1200mhz, but still can't change voltage. Anyone ?

The best is that in boot it has 900mhz+...

May be this can help.

Hello! Might be a long shot try to revive this but...

 

I just bought a 8970m for my alienware M17X R2, but its been stuck at 450/300 all the time, already installed new Windows and checked power options but i can´t seem to be able to change the clocks.

 

Any tips? 

 

Already flashed the card with 2 diferent bios aswell without sucess increasing clocks.
