Started getting stability problems, even at stock Ghz Ed clocks. So I've reverted to the stock BIOS.

Can't wait till next gen cards come out...

Hello before two days I discover this topic, today I've bougt the 7970 DC2T! to replace my XFX 7970 Black Edition which was voltage locked due to revised version 3.1 of pcb, which had no dual bios switch!

DC2T was voltage locked but the card was stable at 1150 - 1650 MHz (XFX not stable even at 1030 MHz for the core). Flashed With Matrix Platinum bios and voila...

My maximum overclock is 1200 MHz with the stock voltage of Matrix bios. I'm very happy about that. Temperature never exceeds 68 - 70 degrees, if we take into account that the six fans of the Haf X case are running on the 30 - 35% of their full speed, when playing games such as Tomb Raider, AC III or benchmarking with the 3DMark 13.
