9800M GTX SLI Issues

Finally got SLI running well on 2 x 9800M GTX, after a fresh install of 64bit Windows 7 and latest Nvidia drivers. Up until that point on Vista I had never managed to use it on any games without strange striping and pixellating effects. (This included Dell installing and upgrading my cards from GT to GTX so the cards were new).

This lasted two days and this morning, with no change from the night before when it had run smoothly all night on Rift, it started crashing about 1 minute into the game. Ran FurMark burn test and was able to reproduce that SLI would last a minute until freezing. Sometimes ending with being able to kill the task. Sometimes needing a power cycle. However works fine with SLI disabled.

For the minute until it freezes the temperature seems steady and rises to only about 70c.

As all that happened between it being fine and then not fine was a night's sleep, I think can discount it being anything to do with drivers, nvidia settings, o/s settings or even hardware stress - as it was powered down. So I'm a little bewildered.

I guess the next test should be to try GPU2 in place of GPU1 with disabled SLI. But I don't suppose that's an easy thing to do with this setup. If anyone has any advice would appreciate hearing it. Thanks.

 

What Nvidia driver are you on?

Have you tried reseatting the cards?

 

I'm using 270.61 these ones:

NVIDIA DRIVERS 270.61 WHQL

And what do you mean by resetting the cards? Do you mean restore in 3D settings? If it's factory reset I haven't done any overclocking or anything like that.

 

No reseating the card as in removing it and making sure it is connected properly. It is a Dell proprietary module. I have seen certain laptops where a card was causing CF/SLI issues because something was not seated correctly.
