My HD 6950 2GB OCing, Modding & Performance Review - Page 2

post #11 of 21
Yesh thats what i'm talking about, i've finished step by step like the following review and wonder thats even on MSI Afterburner I couldn't change the voltage / clocks or any other settings,
So please I still need help someone? is it's probably a problem on my bios version of the Sapphire card?
Should I check maybe another version of bios... from any other companys?

Thanks.

Thanks.
1. Go to the folder where u hae installed MSI Afterburner (typically its c:\\program files (x86)\\MSI\\Afterburner).
2. Scroll and locate the afterburner.cfg file. Make a copy of this file and open with wordpad or any text editor.
3. Scroll down to the last you will find the following under ATI

"Unofficial overclocking EULA = "
"Enable unofficial overclocking = 0" change this 0 to 1
"Unofficial overclocking mode = 0" change to 1 to enable ATI powerplay so that you get lower idle clocks

4. copy and paste the following after "=" in "EULA" "I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it

5. Save the file and rename it to afterburner.cfg and overwrite or replace the original afterburner.cfg with this file.

6. Open MSI AB, now u will see that the sliders' range has increased so that u can OC higher.

7. To enable voltage control, go to settings-->general (in MSI AB) and enable the two check boxes that says "unlock voltage control" and "enable voltage monitoring"

8. Restart MSI AB and you are good to go. BTW get MSI afterburner 2.1 and above to make it work correctly with HD 6900 series.

Hope this helps

Thanks friend ur welcome! this is work awesome now,
I got some of a few question before I will start the OC, I don't really have any of experience, so I will ask you people hopefully you can help me..

Picture : http://img28.imageshack.us/img28/1230/testss.jpg (without OC yet - weird temp of GPU2 in my opinion)

OC Questions:
1) I know the default of the 6970 is 880/1375MHz - if I will change the same parameters I have to put higher core voltage more then 1.1v? or any other option in the MSI Afterburner?


Problem I have notice in the MSI Afterburner:
1) I have just checked how long Core voltage is possible in the MSI Afterburner without click Apply ofc.. and then I clicked on the Reset Button and boom
I had some of bsod... and on the bluescreen I had a message of damage or something, I just hope that I didn't made some of mistake what can make a problems on the software/ GFX card.

2) The temperature of the GPU2 (same card) is like 7c + more then the 1gpu why is that? (Nothing run on the desktop & 0% of activity) I'm scared that something is worng cause in the last month I've feeled of some weird lags for no reason especially when i'm playing games (OpenGL).
But I gave the pc back to the store before 3weeks ago and they're said everything is ok, thats also what I want to believe haha...

They're used Furmark if im right..


Thanks for everyone who's helping me. Keep it UP!

PS : Srry for my english & My newbie Level =)

1) without messing with the voltage you should be able to hit 880 -C and 1375- M comfortably. If you want a higher oc say like 970-C & 1500- M then you will have to bump up the voltage to around 1.2-1.25 v.
But my suggestion would be to leave the voltage at stock & OC to 880, 1375.

2) you should always increase the voltage 0.03-0.05 v at a time and not just drag the voltage slider in MSI AB to the maximum. I think your card is alright, you have just got a warning message from wndows that it has shutdown your system to prevent damage. Its a normal message for BSODs. But whether your card has been damaged or not only time will tell. However 99% chance is that your card is fine.

3) In a xfire set-up one card will always run at roughly 7-10 C higher than the other card simply because it its getting less supply of fresh cool air. Try putting a side intake fan just near the 2 cards and see temps drop by 5-7C. Also set up a custom fan profile in MSI AB for the two cards.

That card is a non-reference model and looks to be a newer revision too. Chances are pretty slim of unlocking the shaders on that one but since you have a dual bios you can safely try unlocking it and see how it goes. Anyhow unlocking additional shaders only nets you a 3-5% improvement. If you can OC it higher to about 950-970 C and 1400-1450 M you will see a greater performance improvement of 15-17%

^ you are doing good buddy. Crysis 2 is like that its unplayable on a single card. On my CF setup it runs at 50-55 fps consistently with drops to low 30s once in a while.
