GTX680 - SLI Issue

[Davepen]

Hello,

Since last night, I am having an issue with my 680 sli setup :/


I noticed my computer was quite dusty, and had crashed, so I thought I would clean the dust out of my PC.

I then dusted it out with an air duster, cleaned all the cards etc, all fine.

But, since plugging it all back in, it seems to crash when I use sli.....

I will get a system reboot, with a "no display" message, when running with sli.

Once rebooted, it does then not pick up the second card.


I have tried each card individually and they seem fine, I have also tried switching their positions, doing a driver sweep/reinstall, and also changed the sli bridge.


I'm really at a loss, I was able to play for maybe 30-40 minutes with both cards last night, only to have it crash and then reset to single card.


Please help!

Does seem a bit odd if they're both working individually. Are your displays setup as two in the bottom card one in the top?

I'm only running a single 27" monitor, so no multiple displays.

You shouldn't have to, but have you re installed drivers?

Yeah, I've completely removed, cleaned and then reinstalled the drivers, still the same :/

After a crash, and system restart, the second card will not be detected.

I then need to shut down, disconnect/reconnect the card, and then it will pick back up on reboot.

For anyone that cares I have solved the issue!

It seemed it was the 8 pin power cable connected to my motherboard.

Half of the 8 pin connector (its 2 4pins with a slide connection in the middle) was coming away from the socket, which I think was causing the PC to not get the power required to run sli reliably.

Must have knocked it out when I was dusting the PC.

Now works fine
