Trouble with SLI 780s and Surround

[Giac]

Ok so where do I start...I've tried 314.22(modded),320.18,320.49, and all the 326 series and I keep stuttering in games. In BF3 the gpus max out, but I still get stuttering despite the high fps. CS:GO the fps drops when there's smoke (wut), Crysis 1 lags an insane amount, even in the menu.

 

When I run any of these games on a single monitor I don't get stuttering...however I think I may have a problem with one of my cards (screen turning green for 1 frame, random shadow glitches..). I ran 3DMark 11 on a loop to see if I get artifacts, and see what the usage was like. I didn't see any visual bugs, but it did stutter, even with fps above 30.

This is the usage for 3DMark 11 with all the settings maxed to tax the gpus as much as possible. does this mean there's something wrong with my second card? I never had this problem until recently, and before 3DMark would max out both cards.

 

Is anyone with SLI780/Titan experiencing similar issues? are you using surround? Not sure whether its just me or I have a bad card. 

 

EDIT: No OC on the gpus btw.

Does the adaptive vsync stuff help.

Try unplug the first GPU and use only the second one, see if is that the problem.

Try disabling surround bro. Or install windows on an old hdd and see if its a problem within windows, since it started recently

I have sli titans in surround. I dont see stuttering. CS-GO should be at like 160-180fps no problem. I also dont see stutter in 3dmark 11. What was your 3dmark 11 graphics score ?? The only game i've seen that really stress the cards is crysis 3 maxed out in surround but even then its might bump down to 55 from 60 fps (I use adaptive vsync to keep temps down).

Are you certain your mobo is totally up to date drivers and bios wise?

Got stuttering when I first launched my sli 780 with 1 sli bridge, put 1 more in and it disapeared, might be the same for you?

tried both sli slots, get the same stuttering. Might get another but I doubt it will make a difference. Running each gpu separately I get no problems. Some games work in SLI and some dont. Alan wake works fine, maxing out both cards. BF3 gets high fps but it stutters all the same. I get random texture flicker that only happens in surround, also at the beginning of each round of CS the screen flashes green or purple. Odd

Updated bios before reinstalling windows. Bios settings are stock

[exyia]

vram usage?

 

but then again, if you're getting a green screen flicker, I would say bad card =\

 

<- (titan sli, 1080p x3 surround)

hmm what I meant was, use 2 sli ribbons or a double bridge.

had a similar instance with motherboard RAM. all settings were AUTO and was told

to set parameters to manual (speed, timings and DRAM voltage) and flickers and

lagging went away. not using XMP profile, but to manually set the primary values in

the BIOS and leave the rest AUTO.

No stuttering here, but i game at 2560x1440, not surround.

Could be two things.

 

1) A dud card, maybe two? Take it back to where you got it from if you can

 

2) Bad/Corrupt sectors on your Hard drive.

 

This is what happened to be about a year ago with Skyrim. I tried multiple things, including buying an SSD and a second 660ti. After reformatting my Hard drive, my stuttering issue went away and has been perfect since.

 

I would try this first to save you some time. Though if you do try this, Please do back your shit up if you haven't lol

Also, Don't back up your games and put them back on your fresh HDD.

 

I know it sucks, but a clean install would increase your chance of success. It's what I did to be safe and ended up working out
