I've had one card for over a year from Newegg, and then recently found an identical one on Ebay for pretty cheap, so I bought it and decided to SLI them. The card from Ebay turns out to be superior and by default boosts to 1188 on the core, as well as less voltage in non 3D states. I'm using this as GPU1. My Newegg card boosts to 1175 and it is set as GPU2. Right now just with a browser open, they are both at 1019MHZ but GPU1 is using 1037mV, GPU2 is using 1050mV...both are at 43C.
Previously I copied the bios from GPU1 and flashed GPU2 with it, and now they both show the same bios version, but they are not following the same voltage and clock regiment. I tried Afterburner and unchecked synchronization...selected GPU2 and clocked it up +13 and it worked, but this will not work when I want to overclock the memory on both cards, and it didn't correct the low power states matching up either. Both cards hit max volts of 1.175 when boosting. One has Hynix DDR5 and the other has Elpida DDR5 if that means anything.
Is it possible to make them identical on every power level through a bios hack or other means? Am I being too anal about it? I cant understand why GPU2 wont just play nice and match the primary card. It doesn't need extra voltage to achieve the +13 on the core, and it's the same temp as the other card using slightly more voltage on the lower power states. I can't figure out why GPU2 is being so difficult. Does anybody have an idea?
