should bigadv TPF vary in the middle of a unit?

I just upgraded to an i7 930, oc'd to 3.85. I'm also running a GTS 450.

In running a bigadv 2684 unit, I'm seeing very significant swings in TPF as it crunches along. Now the last 10 frames were all done while I was at work and nobody was using the computer.

TPF was moving along at about 54 minutes, then all of the sudden it shot up to almost an hour and a half, but the last one was back down in 54 minutes.

I don't have any scanners set to run automatically and process manager looks normal - the bigadv core is using up between 93 ad 96% and the GPU core is using between 4 and 6% of the CPU.

Is this normal behavior for bigadv - large TPF swings?

No. If you have ruled out background processes, then you have too low vcore. Either drop your overclock a notch or bump the voltage up.
 
Short answer: stop the GPU during 2864.
I run an i7-920 at 3.8. My 2684 TPF's range from 35 to 45 minutes, but I don't run GPU at the same time as -bigadv.
You will lose more -bigadv bonus points than the GPU will give you during that time.
 
thanks for both responses. I sure hate to give up the 14K PPD that my gpu gets me, so first I'm going to up the vcore and see if that at least stabilizes the TPF. I can see some swings in TPF if I'm using the computer, but the huge swings I've been getting when nothing else is running except folding tell me something else is going on.

If the GPU is only using between 3 and 6% of the CPU, then wouldn't the amount of slowdown in bigadv be somewhere in the 3-6% range (maybe max 10%)? That should be maybe 5 extra minutes per frame, when folding both bigadv and gpu. Not 20-30 minutes more like I've been seeing.
 
Yeah - the GPU should be reasonably uniform - this huge spikes are what got me with too little vcore - 3% variation then 400% + or hung.
