Ok, so I returned my MSI 7950 and got the ASUS 7970 instead, price drop ftw, but not sure how much I like it as I am having some difficulties with it. First, it seems the voltage is locked to 1.17V as per HWiNFO64. I cannot use the voltage in MSI Afterburner, not does ticking voltage monitor & control does anything (voltage is not there). Now all was nice and dandy, and I had my 2D clocks at 300/150, just like my old MSI 7950. I have installed GPU Tweak from ASUS, and I tried that one, but the voltage is locked there too. Then I tried an older version of GPU Tweak. Some people mentioned that might allow me to change the voltage. No success either. However, since installing that old version now my desktop clocks stay at 500/1400 memory. (i have it currently OC'ed to 1100/1400). I can no longer get the clocks down to 300/150. Now I am not sure if the 300/150 were ghost clocks from my MSI 7950, or if the ASUS 7970 did actually had 300/150 clocks. But I would really like to have those clocks back for desktop use (no point in burning away heat when watching a movie or browsing). Also I would really like if possible to find a way to unlock the voltage, to unleash the card. Right now the card stays under 70c at under 50% fan. such a waste. I don't really like GPU Tweak, so I would prefer not to use it. I'd like to be able to continue using MSI Afterburner, especially since I can use the OC without having to have MSI AB started on windows startup unlike GPU Tweak.
