Problems With SLI

[zepher]

Hello All

I am running

Windows 7 Professional 64-bit
Intel Core I5-2500
2x G-skill 4 gig sticks
2x NVIDIA GeForce GTX 560 TI
Asus Mobo p8p67pro rev 3.0
Corsair 750W power-source

Alright, i am currently using one video-card instead of having the two of them running in Sli.

The reason being, is that when they are running in Sli, the computer randomly restart's, or the display crashes at equally random intervals. (Or i think its crashing, the computer stays on but the screen says no signal)

This computer is running the newest Nvidia Drivers for the Graphics card, The Bios is Alaska 1072009 Bios ver 08.00.10

This computer freshly built, and for awhile (a week or so) the computer worked fine then i started to mess around with the resolutions within games, and then the crashes started to occur. Since then i removed the Drivers that were on the computer and reinstalled them and now the computer is working fine.

It seemed like the longer i left my computer in Sli after messing around with the resolutions in games the more frequent the crashes came at one point i wasnt even able to start the computer because the display would crash right after the welcome screen

Thanks everyone I appreciate any and all help you guys can give me

Hello and welcome to the forums
Do "both" cards work fine simultaneously ?

Yes and no, i am actually in the midst of checking them individually by taking one out of their respective slot and putting them in the other one and testing it using fur mark and such.

It seems like one of them is having issue with the screen going black and then its saying the Driver kernel has failed but has successfully recovered.

This card seems to be doing this alot, where the other card only seemed to have this error when they were set up in SLI.

The error i am receiving almost constantly is "Display driver nvlddmkm stopped responding and has successfully recovered."

Thanks alot i really appreciate it

hmm,maybe one of the cards(or even both) is defective,can you test them in another system ?

Yea i am gonna take them out and bring them to my friends house who has a similar build. I am going to try to run brink which was the game that caused most of the problems the first time, see if i get similar results. Although i think only one card is faulty since i was able to play battlefield for a good 2 hours without having the card fail once but when i switched them the problems seem to occur almost immediately

Thanks i will get back to you with the results some time tonight.
