HD 6950 --> 6970 BIOS Safe For VRAM?

post #1 of 6
Thread Starter 
Is it safe? I heard that you can kill a 6950 by flashing it to a 6970 with the 6970 BIOS because the 6970 runs it's RAM at higher voltages.

But aren't they physically the same card? I mean aren't they physically identical besides the cooler saying 6950? Wouldn't that mean that they have the same VRAM that should run at the same voltage?

Different ram chips are used on the 6970

The 6950 vram is rated for 5ghz where as the 6970 ram is rated for 6ghz

It also uses different voltages and different timings, which maybe why it can have a negative affect on the 6950s.

Grab a custom 6950 bios that unlocks the shaders only, and keeps the ram and such at stock

Then you should be gravy!

There are some reviews that show that a full 6970 BIOS will perform better than a 6950 unlocked BIOS, that's why I'm wondering.

Been running mine for what 2 months now and no problems. Pls dont use Furmark or OCCT as they just try to kill the card. Also make a custom fan profile. Even if the RAM is rated for 5Ghz dont we all OC our system ram and lower/play around with timing and nothing happens other then overheat but if you keep ur card cool its should be fine with stock HD 6970 BIOS.

Hmm, I have the problem of Afterburner (for the fan profiles) cancelling out CCC's +20% power setting.

Right now what I do is just start CCC first then apply the settings then open afterburner. I wish there was a way to set custom fan profiles in CCC.

So I guess I'll flash to 6970 BIOS and see how it goes.

What does PC do? I just checked mine an it was 0%. Been playing Dead Space 2, and Crysis for 2 days now and no problem.
