Jesus i really regret selling my old reference XFX Core 7970, it was able to hit 1150/1600 at 1.150mV 75C 55% fan speed - there was a few reasons why i sold it (loud, non reference PCB incase i wanted to get an Accelero, etc)
In any case i got a Gigabyte Windforce 7970, and the stupid thing was voltage locked - wouldnt even sit at 1100/1500 without crashing...sure it was cool..but whats the point
So i decided to return it and grab an Asus Matrix Platinum price matched to $499CDN, and its not stable at 1230mhz@1.33mV hits about 81C before artifacts show up in Heaven demo - the XFX was $369CDN, about 25% cheaper
One weird thing is that i cant seem to overclock the speed without also overclocking the voltage - so it may be a heat issue, i dont know why the speed and voltage are binded together
I saw on other threads that theres supposed to be a little lock icon so you can change them independantly?
Also - i hit the +voltage button on the card itself so that its about 75% of max (purple) and set the Power Target to the full 20%
Should i also change LLC? Currently at 75%
Any tips would be appreciated - my last option is to either try and exchange for another Matrix and hope for a better GPU (this one has ASIC quality of 67%, my XFX was 87% - not sure if that matters) - or just call it a loss and pick up a Reference MSI 7970 for $359 and hope it doesnt come voltage locked.
