Bios upgrade from 6950 to 6970 problems.

post #1 of 6
Thread Starter 
Upgrade went fine. All shaders and clocks now running at 6970 speeds.

But now when I try to run 3dMark it crashes my computer on the second test. Not sure if this is due to heat or the overclocking. All tests worked fine before the change.

Should I try to tweak it as a 6970 and get it stable or go back to the 6950 bios and just unlock the shaders after that.

It's a Sapphire 2GB 6950.

I say tweak it as 6970. Most probably a heat issue, custom Fan curve from MSI AB should solve it.

Set fan speed to 100% and run the test to see if it is heat. Make sure to grab some earplugs

You're better off going with the unlock shader method. When I had the 6950 6970 bios flash it would go incredibly unstable past 920ish on the core. Unlocked shaders allowed me to reach 1040/1350 1.3v no problems.

First thing I would do is drop the memory clock down to stock 6950 speeds (it doesn't affect performance anyway).

I bet that solves your problem.

K dropped the clocks down and reran tests. All good.
I'll live with these results until I can come up with better cooling for it. It destroys everything compared to my old 8800 anyhow.
