I'll try it in a minute. 32GB of DDR2400 should be pretty definitive.

Are you using Reaper or CGMiner? I have two rigs with 3x7970s and they work fine with 4GB of ram at an intensity of 20. Cgminer, Win 7.

That's interesting. I'm struggling with this problem now with a 2x 7950 rig. Even Intensity 13 is giving me some errors.
I have 4Gig RAM, so maybe I'll pick up 4 more...
Can you post if you notice you are getting errors again.
Thanks,

Hallelujah I have solved it.
If you have a radeon several 7950 or 7950 cards and can not raise intensity past 13 or gpu threads past 8000/8192 without getting HW error or crashes, the problem is caused by a lack of RAM. I had the same problem on my 3 GPU rig and no matter what I did I could not fix it. Once I upgraded from 2GB to 6GB of RAM everything worked perfectly and I could raise the intensity past 13 and the threads to 21k+.
