A lot depends on the individual card itself and the cooling you're using for it ...

most 6950's come stock voltage at 1.1v ... the TOXIC I think is the only one that comes stock at the HD-6970 level of 1.175v,

OverVolting from there in general ...

1.25v is usually considered safe for AIR / stock cooling ... and ...

I might add! I was able to get the core to 1030 MHz and memory to 1550 MHz, but that required 1.3v and the performance increase didn't warrant the additional voltage and in some cases, hurt performance.

so most suggest NOT going above 1.26v unless you're on WATER, and have one of the HIGHER Quality Cards ... Sapphire TOXIC, MSI PE/OC TF3, Asus DUC2TOP, PowerColor PCS++, Gigabyte GV-R695OC-1GD, HIS IceQ X Turbo X and the like ... basically scaled down 6970's.

 

So basically anything above 1.26v you risk not only a performance decrease from degradation, but you also risk premature life shortening damage to the card from excessive heat it wasn't designed to handle 24/7. There were a couple other threads a while back that had this SAME question, but my search I couldn't find them fast enough ? but that was the basic consensus then as well.
