And I thought I have the 7950 with the highest ASIC quality (90.7%)^^
stock voltage: 1.013V
I'm currently using my card at 1100/1250 @1.100V
(testing 1575MHz on mem now)

Crysis 3 beta runs like a charm since bumping voltage up to 1.1V (because of one single frezze that didn't occur throughout my BF3 testing)

I consider this a totally safe overclock for everyday use as the stock voltage of the 7979s (same chip) is approx. 1.170V

btw Sapphire 7950 OC 950M here

I have heard different reports on how much ASIC quality means, but I've had 2 7970s, each of which artifacted/coil whined, and both had ASIC qualities of around 70% (~67%, ~71%). Neither one was even stable at default clocks. Lesson learned; never touching an HIS card again.

Sounds to me like if you get anything less than (edit) 75 you should probably RMA to prevent future worries.

Edit: unless you are planning on pushing a lot of volts with water cooling, etc. because that high voltage seems to work well on low asic cards.
