[bluefire908]

Hey guys,i jst got my spanking new 980 sli setup and ran unigine heaven to check my scores.I got a score of 1550 with sli (1440p res and all settings maxed except for 3D).then i ran it without sli and got a score of 1900.Some thing was off so i ran heaven again while monitoring my gpu usage,without sli my single 980 had a usage of 99% with sli both of my cards keep bouncing on is at around 93% the other is at 85% and sometimes drops to 70%.

 

System specs

 

core i5 4690k

gtx 980x2

Corsair powersupply 650 watt 80+gold (forgot the name )

 

EDIT:ran benchmark again for fun with sli and got a score of 2100(not overclocked my cpu yet)BUT STILL ITS CRAP I GOT 1900 WITH SINGLE 980

 

EDIT 2:i overclocked my cpu an re-ran the benchmark with no improvement :-( some help would be awesome guys

Just try to turn up the Clock speed as mch as you can on stock voltage.

Guru3d says yes, and I don't think you can be more trustworthy than them.

Try turning up the voltage a see what yo can get with that. Do keep in mind that sometimes these "scores" aren't as accurate as you would like.
