Please use this thread to discuss Asic quality and its effect on temps and overclocking.
Post your Asic score as shown in GPU-Z.

The ASIC Quality screenshot can be evoked from GPU-Z's context menu and is individual for each graphics card and GPU. (Right click the GPU-Z Title bar with the software open to show Asic Quality of your card.)
This feature has been developed for Nvidia’s Fermi (GX10x and GF11x) and AMD’s Southern Islands chips (Radeon HD 78xx and HD 79xx) and is supposed to indicate the quality of the specific GPU, in percent, based on electrical leakage data.
The higher this number, the lower voltage the GPU needs to work at the default clock rate and the higher overclocking results you can get with it by increasing its voltage.
According to Alexey Nikolaichuk (the author of RivaTuner and MSI Afterburner), the correlation between voltage and quality is as follows:
ASIC quality < 75% - 1.1750 V;
ASIC quality < 80% - 1.1125 V;
ASIC quality < 85% - 1.0500 V;
ASIC quality < 90% - 1.0250 V;
ASIC quality ≤ 100% - 1.0250 V.
My Asic
I always believed that high asic 7970's ran cooler, however recently ive heard that low asic 7970's run cooler as there is more leakage so less heat is generated. I'm interested to hear from people who have bought more than one 7970 and have used different asic cards.

) said that actually higher leakage (lower asic) cards run cooler because of the said leakage.
