is 1.30v too much for this card or is that good for a 24/7, temps haven't gone above 53C even at 1.3v 1200/1500
are there any tweaks to CCC+afterburner I can do for more compatibility as well.
edit: according to this
http://forums.overclockers.co.uk/showthread.php?t=18386056 I'm at the low end of a 7970, so not bad all things considered.
What water block are you using to achieve such great temps? I am with EK's FC7850 and the temps go to low 60's on my HD 7850@1200Mhz and 1.18V. When I had Supreme HF VGA on the temps were significantly better, never exceeded 50 really, but that was just on the core, so other things like RAM and VRMs did not contribute to that. I may have to re-sit the block...
I reckon that if your temps are that low there is nothing to worry about even if you push 1.3V through it, just remember to cool VRMs too and you should be fine. Also remember that your card will not be running at that speed all the time, it will clock down to something around 400Mhz if not generating heavy demanding 3D graphics, so it will be fine for 24/7 usage.

:D:D:D It will be here on friday !
I will try to get my 7850 to be stable @1300Mhz so far I have failed rising the voltage to 1.225V
