hello everyone

Yesterday i've bought a "Sapphire HD 7950 Dual-X 3GB GDDR5" with core clock 850MHz and boost clock 925MHz and one pair six-pin PCI-E connector.

I heard about that hd 7950 can upgrade to hd 7970 by unlocking SUs. So I googled it several times but found nothing.

can somebody tell me how to unlock my card? and if i do it, will it damage my card? (its too important for me.)

tnx :)
