Couple questions regarding my GTX 680 Lightnings SLi.

post #1 of 2
Thread Starter 
Ok so recently I bought another GTX 680 Lightning and have two of them running in SLi mode. Well on the first card I bought I switched the bios to the LN2 and Flashed the card back to an older bios ( same the the first 5000 cards have) Well now that I have my second card in there I just looked at GPUz and noticed that the two have different clocks. My First card went back down to 1006 or something close to that. And the second is what its supposed to be 1176. So in order for them to run correct I DO NOT sync the clocks and just overclock the first to equal stock clock of the second. So my questions are did the clock go back like that because of the flash or LN2 bios? Any suggestions. Also the second card I bought is supposed to be one of the 5000. But still does not have the power adjustment up to +300 like the card I re-flashed. Should I flash the second to get the same bios on both? Basically I want to get the clocks in line before I start to overclock them both and would like to be able to sync the cards in MSI afterburner. But cant right now because of the different clocks.

I would say the clocks are different because the 1st card is using a different BIOS which could case non-stock speeds/voltages to be running.
