6950 overclocks

post #1 of 11
Thread Starter 
I just got my water loop running and am impessed by the temps I am getting and want to overclock. I have two 6950s in xfire running at stock currently. I dont want to flash to 6970, just overclock. What utility is best to do this, and what clocks/voltages have othes gotten to work stable?

I appreciate your help.

MSI afterburner is the best software for this, very easy to use.

You can OC the memory, GPU and also increase the GPU voltage.

Once you install the software (google for download), you'll need to edit msiafterburner config file inthe Root of the MSI afterburner folder. this will allow you to go up to 1.3 core volt and increase memory and GPU speeds past the recommended MAX


You'll need to replace\\add the following at the bottom of the config file.

I downloaded a couple different version of MSI afterburner and made the change you suggested above, and when I change my clocks to anything besides stock, I blue screen. I did only a mild overclock (840/1300) and it still blue screened me. Any thoughts?

I have the same problem, i flashed the bios with the shadders unlocked as well as 1.175v only (stock 6950 ram volts/timing), and i cant go over 850mhz core clock... i guess we just got unlucky

Add a little voltage. 1.175 for starters on a 6950. That's stock voltage for a 6970 at 880 MHz.

you have to disable ULPS if you use AB and have CFX set up. Its a reg hack, search for ULPS in this forum and you will find the instructions on how to do it.

Err? You shouldn't have to go near the voltages for that OC.

I have mine currently at 900/1400 and i've not touched the stock voltages, their still @1.1 (Im using Sapphire Trixx).

Try your OC with stock volts to test.

I agree, it cant be voltage.... it seems that I change it to anything and it reboots after a memory dump... ill try the ULPS stuff after work and see what happens...
