Anyone running 2 x 5870 in crossfire in Windows 7? I can get them to run at 970 but I find that from time to time the system will BSOD, yet the temps are fine. Highest it ever reaches is 74c.

Is it possibly the crossfire setup being the cause? The reason why I'm using a crossfire setup is because it's running on Windows and I haven't got any dummy plugs.

1x5870 + 970/300 on Windows gets me 412 mh/s in phoenix.

I'm currently running the crossfire setup at 950/300 at the moment to see if this prevents the BSOD.
