Sli uneven voltage

[MasterOC]

Is it normal for one card to have a lower voltage then the other in sli ?

I have two 970s and one card dosnt reach the same voltage as the other.

Separately they both clock a lot higher and both reach the same voltage but put together one decides in will run lower ?

Hmmm , i've encountered the same issue , i think it maybe a monitoring issue rather that a hardware level issue , i have 2 reference 780ti's, one is a Evga sc the other a ref gigabyte, both are running the same bios (Skyn3t), however with the voltage untouched one card hits 1.818v max the other 1.200v , and lowering the voltage on the second card *seems* to have no effect.

Solved it for me. Both around 1.25 now. Trying 1500 core for a while. Previously stuck at 1450.

That's ridiculous , looks like I'm not the only one , its limiting the stability on one of my cards when overclocked @ 1466 . Both cards can do 1500mhz on there own... I don't like the idea of un syncing clocks. Surely it results in a worse viewing experience in games and benches.

( ok so I did that exact thing and now both boost past 1500mhz netting healthy boost on firestrike extreme , do we think this will be rectified by NVidia ? ) couldn't get my voltage matching despite the higher clocks , 1.200v , 1212v
where as one would top out at 1.200v and one wouldn't even do 1.137v !! that was really limiting my overclock !!
