I don't have the problems some do, but I'm just running the old stuff... 58xx and 69xx. On occaison I get the hung WU but it isn't all that common and when I do I I usually lose several hours of a GPU. I don't babysit the computers.

What I found on MY systems is:

1. The app_info works excellently with single cards. Gives 5% or better increase in credits.
2. On a dual card system (6990) it caused bunches of 590 credit WU (I7 2600k). Even though my crunch time went down per WU I got far less credits. 26 590 credit WU over a 16 hour period. When running 1 WU per GPU I almost NEVER see 590 credit WU.
3. On a dual card + single card (5970 + 5870) system I got bunches of hung WU. A hung WU is RARE on that system when running 1 WU per GPU.
4. A Q6600 machine with 2 5870s barfed almost immediately with only 2 cores reserved. I didn't try freeing all 4.

On #2 and #3 I was reserving 1/2 of a V8 ... it might have worked with more CPU reserved or it may be a function of the "dual" GPUs. I don't know but it isn't worth worrying about. I'm heat limited at this point so increasing the GPU loading by 5% isn't beneficial! All but 2 cards are downclocked.

I'm getting 4M+ per day (normally) so it pays far better than anything else.

Z you might try shutting down CPU crunching on your 7970 machine and try a 24 hour experiment. Before I did the Collatz Pentathlon thingie I was running Donate to the tune of 4.3M per day (winter I could clock higher). Although I did see hung WU they were VERY rare. After the Pentathlon I went back to Donate and for a couple of days I had a lot of trouble. It finally dawned on me the difference between before and after was the amount of CPU I was using for crunching. Prior I was reserving 4 threads on the V8s and after I was crunching 6 CPU wu and doing Donate. I reserved 2 more threads (1/2 the I7s) and my problems went away. Anyway it might be worth a try on one of your systems!
