Xfx 7970 black edition, poor at overclocking?

I bought an XFX 7970 DD BE at launch and max stable clock was 1200/1710 on 1.21 Vcore, stock Vram.

I've heard that recent versions of the card are voltage locked - is yours? How are your temps? Do you have a good enough Power Supply?

Use MSI Afterburner to handle your overclocking, by the way.

And as always, overclocking depends on luck of the draw - you may have just gotten unlucky and not gotten a card that OC's well.

I havnt tried to unlock the voltage yet so im not sure about that. My psu Is 750w ozc fatality series. I will try saphire trixx or msi afterburner later and i will post the results. I would of thought this card could at least achieve the maximum overclock using ccc without any problems at stock voltage.
