^BTW its VRMs already stressed with addition shader load. dont overvolt too much IMO.
is someone able to find some nice links in this regard?

yeah, your gpu might not run stable at 880/1375 without extra voltage.
you can overvolt using sapphire trixx.

and remember to up fan profile before over volting.

Temperature is fine.

Don't overclock to 880/1375 if you get problems.

Either keep it at stock i.e. 800/1250 or overclock to something around 830/1300.

+1 ..

And @OP, ur psu is fine, don't worry.

is someone able to find some nice links in this regard?

If i were nt wrong, u r talking about unlock/tweak the 6950 to 6970, am i right ? If yes, go to guru3d forum, and search for ' dave's ' article regarding unlocking this gpu. U can find a sticked article in there. As i know he is the 1st person who unlocked this gpu.

^i want some info on overvolting unlocked 6950.

Congrats Jas, Awesome Job with your card. Now Enjoy Doing Hard-core Gaming.

you can overclock the GPU clock but dont overclock the Memory clock much as it may cause instability.

i already run the memory at 1375.

Unlocked Sapphire HD6950 Dirt3 Edition

Just recently picked up a Sapphire HD6950 Dirt3 Edition. So far I am very pleased with the card. Shaders unlocked with the bios switch flip and it is a pretty solid overclocker as well. 970/1370 @ 1.18v stable

nice - I think now you've got what you were looking for - do let us know the results if you are going to apply 1.18v

Hi, I have the Sapphire 6950 1GB(dual fan) dirt 3 edition and after seeing this thread, I shut my PC down to look if my card has the small BIOS switch. It turns out there is actually the magic switch that I was looking for. I turned the swicth to the right, open my PC and launched GPU-Z and BAM! 1536 shaders. I was really surprised because I had a factory pre-installed 6970 BIOS in my GPU.

However, I switched back to the stock BIOS (1436) because I was worried about breaking my card. What do you guys think? Should I use the pre-installed 6970 BIOS switch? Keep in mind I have the 1GB edition. Thanks.

^^ just use the the magic switch to enable 1536 Shaders and get extra performance - if the card remains stable through games and benches then congrats - you got a HD6970 and try bumping up the core and mem speed ( without changing volt ) similar to HD670

Well, I bumped the Core clock to 840 and the memory clock to 1325 with the unlocked shaders and I put the power control setting(in CCC) to +20. I've tried going with 880 and 1375(6970 clocks) but I got random freezes in BF3 so I guess it's stable at 840/1325.

Btw thanks alot for your response.

^^ looks like that's the limit but after 840/1328 core/mem speed try to increase the core/mem clock by 5 mhz only on each step untill the card becomes unstable in games - thus you will find the maximum stable clock speeds for your card

Thanks again for your reply, and one more question, am I suppose to add more core voltage to the videocard after I've unlocked the extra shaders? Because I've tested with 3 softwares(trixx, CCC and msi afterburner) and they dont allow me to add more voltage. Only the power limit which is on +20.
