It doesn't matter really cuz all silicon is pretty much unique. Just because it does 1125/1575 on stock voltage, that doesn't mean it will hit 1300/1750 on water. I experienced this exact thing, came across a 67% card that did 1125/1575 stock voltage, but it couldn't take max clocks. mad.gif

Uinstalled furmark, it's true, gaming doesnt stress the card that much and for me it is the gaming performance that matters thumb.gif
Will try to OC higher when I got time, it's fun too see that I can get even more out of my nice HD7950 biggrin.gif

Edit: Couldn't hold the OC fingers back biggrin.gif Got higher OC again, tested with Unigine Heaven and Battlefield 3 multiplayer to confirm stability and it's stable!
What a monster card it is wheee.gif 1125mhz core (stock 880mhz) and 1575mhz memory (stock 1250mhz)!

Get better gameplay in BF3, no big drops at all, FPS around 40-80+ with all ultra settings and unigine heaven 3.0 gave me higher score and FPS! thumb.gif
Temps I've seen doesnt go any further than 70-72 degrees !

Every card i have heard of can make 1125 stable unless you are on stock voltage?

1200+ is when the fun beggins;)

What could cause the #2 gpu in cf not to downclock to 300 at idle? Only running 1 monitor on top card but at idle the clocks look like this: gpu1 300/150 gpu2 500/1375 which makes the second card run hotter at idle. Also using afterburner 2.2.3

QFT. In fact, the card that will do 1175MHz on stock won't go past 1230MHz at max voltage... redface.gif

MSI 7950 TFIII: (ASIC 91.5%) -- great card except for the fact that it sounds like crickets in my case! rolleyes.gif

Gpuz or heinfo64 or any app that actually reads voltage. AB does not read real voltage, it only displays your input voltage, ie. what voltage you set the slider to.
