sapphire 6950 unlock pre-emtive thread - Page 2

post #11 of 13
Have exactly the same card, flashed it and went fine for the most part, biggest issue is temperature has the fan profile in bios at least in my case isn't adequate and allows the card to heat up too much, the cooling power of the although is more then enough the balance is in noise/performance, using afterburner fan control (automatic one), and was able to lower the card temperature from 90+ to around 70ºc without going def.

Some people have claimed dead cards after a month or two with the 6970 flashes. Current thoughts are the 1.6v mem voltage might burn out the lower rated memory on the 6950. Although, 1.5v to 1.6v is less than a 10% voltage increase, so I'm not sure.
Volts are GPU 1.175. Had two a week since release, no problems so far. But they are watercooled.

Ok I just bought the Sapphire 6950 2GB, but the one I received didn't have the bios switch....

Can I still unlock it?

It's hard to find info regarding the single bios version of the card
