What version of stream sdk are you running?

I am running sdk 2.1. Crossfire has been disabled. Cores are definitely not overheating, avg at like 60c and 99% load. Appreciating the suggestions!

Edit - I got it working! I think I either disabled crossfire wrong, or redoing the aticonfig commands fixed it. Thanks for the help guys!;

I got everything working except one problem. I keep getting "Verification failed, check hardware!" on the 2nd GPU of my (bought used) 5970. I tried underclocking, even down to 560/1000 and it still does it very often. I swapped in a 2nd (bought used) 5970 and the same thing. It works, it just shows a lower khash rate and lots of errors. The whole time core 1 is happy not a single error on both cards.

What would cause this? Any ideas? I'm skeptical of used hardware, but the fact that both cards show the same behavior gives me hope its a config issue.

I'm running Ubuntu 10.10 with m0mchill poclbm. Motherboard is MSI-7599 AM3 spemron with 2 sticks of kingston 1gb pc1033 dd3 ram. Corsair 1200w gold psu. Motherboard is just sitting on workbench at this point until case gets here. I have DVI monitor plugged into lower dvi port of the card. Switching to top doesn't help.

Help! Thanks

Sounds to me like you have cross-fire is enabled; if that's the case - you need to turn it off by typing:

Code:

$ aticonfig --crossfire=off --adapter=all

Or, like bitjet suggested, you are using a wrong ATI Stream SDK (like 2.2 or 2.3).
