I used the render test to load the GPU and then ran the ASIC quality, and it stays the same. Will be interesting to see if Duffman sees any change.
I'm wondering if it just reads the default VID, more voltage = lower percentage rating?
It might help if people post their core voltages (the bios one not software overvolted) along with the percentage.
Those with the highest ratings appear to be stock cards which are unlikely to be factory overvolted.
