8600 GT Problem

[Darren]

I have 2 Nvidia 8600 GT cards SLIed but the drivers keep crashing out and now when I look at GPU Z one of them is running at bus speed PCI express X16 @ 8 and I am wondering if there is anything I can do to solve the problem or do I just have a bad card. Any help would be greatly appreciated.

Your card is fine but unfortunately your motherboard only supports PCI-E 16x with single cards. It downscales to 8x when PCI-E SLI is enabled. It's just a feature, most motherboards except for the really expensive ones do this. It's normal, problem solved.

As for the crashing issue your going to have to give us more information, does it crash in games, dvds, on desktop? What is your full system specification?

Well I am not sure about crashes anymore I downloaded the 174.74 driver last night after someone said too and I have not seen a vista recovery yet so that might be solved my only issue now is if I have SLI enabled when I log into World of Warcraft it looks like there is 2 copies of the graphics going: one in normal position and one that is shifted about an inch to the left and gives it this very weird distorted look but every time I screenshot it the screenshot looks fine.

WoW has a known issue with sli its better to run it in single card mode.

I have had many Biostar Tforce 570 mobos.. They run the 8600 and 7600 series fine in SLI. (the PCIX 16 is more for 8800 series and up)

Try reversing the cards,

What PS are you using?
Are you using the 8pin for CPU power?
Are you using the extra 4 pin molex for SLI?
Are you using a 24 pin for power or a 20 pin?

When you remove the drivers (before installing the new ones) make sure to run Driver Sweeper first

My best friend had that exact same problem with two Inno3d 8600GT cards, he had a 590i chipset though. We never could figure out how to fix it, we reinstalled windows, installed diff versions of drivers, game patches. Nothing worked. We finally decided that it was time to turn off SLI during games that did that.
