Problem with SLI and 8800 GTS

713 Views 5 Replies 2 Participants Last post by  dai
Hey. Lately, I have started to game again, and my video cards are messed up. I got 2 8800 GTS running, and whenever I put it in SLI mode, the graphics in game are slow, horrible, but as soon as I put just single card, its fine. And I have replaced both card slots, tried both, but still same prob. Each graphic card is fine on its own, but as soon as I do SLI, its messed up. Also, one of them is OC and other is OC2... i dont know if that would have anything to do with it.

I was wondering if anyone knew how to test my graphic card for hardware issues, or if the OC2 and OC is affecting this whole thing, but I'm pretty sure, last year when I got the second card, it was running Crysis in SLI at way high FPS.. so thats why I think its hardware.. any help is welcome. Thank you!

i attached my dxdaig too, for specs and stuff

as for the psu, im trying to figure it out.. i just noticed the psu fan is dead.. its not even moving.. trying to figure out if a wire is loose...\\but the psu itself is not even close to hot.. barely warm, maybe the fan is energy saver crap?

its a ultra xfinity 600 watt "some nvidia SLI ready" logo
+12v1 has 18a and +12v2 has 20A

you need a min of a quality 850w to run that system in sli

all temps are to high probably caused by the overloaded psu
whatt? you sure about that? i used to run this in sli a year ago with crysis and it was fine.. and the temps dont seem to be that high

is there anyway to underclock somethings so it could be possible to run?
