Radeon HD8970M stuck at 450/300mhz

Recommended Posts

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+...

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.

      I have tried to update nvidia drivers of my notebook ge72vr6rf apache pro. The only drivers that works are the ones provided by the msi. The problem is that they haven't updated those since 2016 and I can't play newer games. 
       
      Some say you need to mod your 1060 drivers, which I have no idea how to some says you need to update the flags in ini files. So please help me
       
      Thanks for your time.

      Dear modders,
       
      Hope you all are doing well. I wished to ask if someone could guide me for flashing a vbios to the GTX 970M 6GB for to be installed on the MSI GT-683 laptop (with modded GTX 560M heatsink). I need to know how to get a display to be able to flash (also, flash with what software?) if the gtx 970m is of clevo (is the IGPU supposed to work? do i need an unlocked laptop bios?) I intend to buy this GTX 970M : https://www.aliexpress.com/item/4000264805962.html?spm=a2g0o.productlist.0.0.62d77e93DGQl5O&algo_pvid=bccc80d9-9944-4dc3-a1e6-ef3d45bda0e3&algo_expid=bccc80d9-9944-4dc3-a1e6-ef3d45bda0e3-5&btsid=12b502b9-dbe1-4c35-be48-930446a31235&ws_ab_test=searchweb0_0,searchweb201602_3,searchweb201603_53

      Hey y'all! I'm planning on releasing BIOS mods for the newer MSI laptops.
      So I'm looking for some testers to evaluate my mods and give input.
      If you're interested just PM me and we'll take it from there

      There are several threads on requesting BIOS modifications here on T | I but I thought another one wouldn't hurt.
       
            Your request should look like:
      Brand Model Type of modification(For example: Unlocked, added support, Logo, microcode, ME firmware etc  
      I'll respond as soon as I have time as I'm also currently working on other projects(Requests by PM is also ok)
      If anyone else have the knowledge and time feel free to respond to requests
