Overclocking a 6950/6970

[Dirk Diggler]

I've never worked with the red team. Do I just load the latest AMD driver, open AB and push core and mem until the card falls over? Just like a team green OC?

Is there anything I should know?

The card is under water, so temps shouldn't be a factor?

Yer, same as always bud. I have had a 6950 and it wasn't a bad clocker as I remember it.

It's dual BIOS and effectively a 6970 so hoping for good results.

You can also click the "unofficial overclocking" thingy in AB as well. I could max mine with the normal slider and this gave me more to push. Do the same for voltages as well.

Looking back, mine was a proper 6970 and is top in a couple of benches

Mine flashed to 6970 no problem and clocked great to

I can't get the voltage slider enabled in AB, even though I've selected to unlock voltage control.

Did you do a restart?

Did you do a restart?

AB, yes. The PC, no.

Do I need to restart PC?

some cards can be voltage unlocks some cannot but overclocking the 6950/6970 has little gains I thought ? like 1-2 fps more
I know when I clocked my 6970 the gain was tiny

If I remember correctly I had to but it was a long time ago and sure it needed it.

My old 6950 overclocked like a beast! I can't remember exact numbers now but it was like a 20% overclock.

Followed it, but no joy. I even scoured the net and found the version of AB the guy used at the time, but still no joy.
