980 sli issues

[karlos1995]

ive had one gtx 980 for almost a year and this week ive added a second one into sli and im having quite bad performance,

 

in fallout 4 im averaging 30fps with quite violent spikes up to 60 then straight back down that makes it very unplayable 

 

in arma 3 im averaging 20 fps and only rarely goes over 40fps

 

in both these games i had 50/60fps before the second card was installed

 

my running 1920x1080 at 60hz (the second card was bought because i was about to buy a new monitor and move up to 4k)

 

id just like help fixing this lack of performance before ive had the card to long otherwise i cant take it back since im think about doing that and selling the other card and useing that money to get a 980ti

 

OS- windows 10 x64

cpu- 4790k 4.0ghz

ram- 16gb ddr3

GPU- gigabyte g1 gameing geforce GTX 980 x2

motherboard- Z97X gaming 3

power supply- thermaltake 1000w gold

Are drivers updated?

[Whorax]

Have you taken the card back out to see if the problem fixes itself with one GPU in? This would be what I'd do, after making sure drivers are updated of course.

[HmmR]

bro i have a gtx 970 and i run fallout 4 at 65 to 70 fps 1080p

 

you have a gtx 980 you should be able to run it at 80 fps atleast

[karlos1995]

someone has already walked me through useing DDU and downgrading my drivers to 347.88 and the performance is still the same 

i havent taken the card back i only got it 2 days ago and i want to make sure its not a problem with how i have it set up or something else on my end and the person that had me do the DDU thing said my 3D mark scores were good and that the card and sli was working (after doing the DDU thing it went from the score off 18223 to 17771) im not sure if thats common or if the old driver just dosent perform as good

Check the cards with GPU-Z and post the screen shots.

Also Fallout 4 is one of those games that breaks when you disable v sync cuz it was made for 60 fps or lower.

[karlos1995]

i changed the sli bridge position and im getting a little better fps in fallout 4 but i couldn't find a single v sync setting in falllouts settings so i couldnt turn it off 

 

i tried to play arma but the screen stutters like crazy like it gose black then picture the black then picture but dose it so fast its like a strobe light so its either corrupted game files or the card isnt playing it properly now
