Title: Underclocking 6950 ram w/ afterburner need 2.1.0
Post by: AlexWaters on July 21, 2012, 07:07:30 AM
-I recently purchased a new MB and SSD
-Installed windows, drivers, etc. on the new drive

I used to be able to underclock my two 6950s RAM to 310mhz with MSI afterburner. I would have to pull the slider all the way down once, apply, close, open, and repeat to get it to 310. I had the EULA unlock text added to the .cfg file etc.

With this new setup I cannot get it to reset the slider position when I exit and reopen afterburner. I have a feeling that the issue lies in the version of afterburner I just installed.

I can only find newer versions of afterburner on guru3d. Luckily I hadn't reformatted my old drive yet, and can see that I was running afterburner 2.1.0.

Does anyone know where I can get this older version of afterburner? If we can confirm that this is indeed the problem, it might help a bunch of other people trying to underclock their 6950s (from what I've seen; unsuccessfully.)

Thanks!

I found it here:

Tested, seems to function as one would expect.

Have you tried flashing on the 6970 BIOS for unlocking more shaders, too?

6950 specific
I do not recommend using the 6970 firmware. Instead use your original firmware, but modified with the "shaders unlock" patch. There have been several reports of permanent damage, probably because of the different voltage and timings used in the 6970 firmware. It will also make the card use more power, which means higher cost and quite a lot more noise from the fan.
