Ahh,

So increasing the voltage makes the card more or less stable?
Whats the rule of thumb?
Whats the rule of thumb?
700mhash at 1175 was about right. That said, getting to be summer here so I have dropped to stock speed and undervolted some to reduce heat and save on the electricity and A/C bill, which brings it down to around 555mhash.
More voltage allows higher stable clocks, but also increases heat generated (and electricity used), and heat in turn can make the card less stable. Basically voltage will make the card stable at higher frequencies if you have enough to cooling to deal with the extra heat, to a point.
I have this card and highly recommend it. When deciding to buy it, it seemed to be the best card among the "regular" priced cards. Fan is very quiet even up to 60% and keeps temperatures low. Max OC WITHOUT adjusting voltage was 1175 stable. 1212mhz would run for a few minutes but eventually crash. With voltage bumped I bet it would go higher, but I am trying to keep temperature below 60C at all times to increase the lifespan of the card. That said, it's the only 7970 I have bought so I don't have another card to directly compare to.

hash rate at 1175?
And yeah, those Sapphire coolers are pretty great

All 7970's are reduced price now. It was reduced by AMD to be competitive with nvidia 680 GTX as far as games are concerned.
Just FYI

This price has a $10 rebate included...
If you don't mess with rebates, $459.95
Comparing the back of the picture to the Koolance site instructions, this is a reference card.
Ready for a cooling block.
