GX2s acting up again.

post #1 of 12
Thread Starter 
Okay, so while I'm away this weekend I wanted to have my i7 folding SMP (don't have enough WUs for bigadv yet), my 9800GX2 folding for my team, and my 470 folding for me. Unfortunately, every once in a while, my PPD drops down to about 100 on the 9800GX2 (both cores). It folds fine for a while, then the TPF goes up to something crazy like an hour and a half. Any suggetions?

This is the log file. You can see the timestamps get farther and farther apart. Could it be because my PSU isn't big enough to handle them all at full load 24/7?

Thermal throttling?

EDIT: if your PSU was overloaded it would trip out so it doesn't melt

They both get to about 80c, which is perfectly fine for GX2s... I've had them folding higher before.

The StealXStream 700W PSU isn't exactly the highest quality power supply out there. If you've had it for a while, it isn't far fetched to think that it is dying.

Grab a PSU tester and make sure its putting out the right voltages. Also, are your clocks staying at what they should be, or is it dropping them into 2D?

My GX2 does the same thing from time to time... drops to 100ppd on both cores.

Fortunately it has been a while since it did this. I think I might have fixed the issue by using dummy plugs. Not really sure though.

Mine never did that, even when I left the fan control down accidentally and it folded at 114C for about an hour.

I'm inclined to say PSU, although I'm no expert.

I'm disinclined to say PSU, but it's always a possibility. Run it with the flags -gpu 0/1 -forcegpu nvidia_g80 -verbosity 9. That's how I always ran mine, and they never really gave me any trouble.

if you have overclocked them at all reduce them back to stock, or as others have said before they may be resetting to really low clocks to not... die, i have 2 9800GX2s myself and both run fine stock on the latest drivers
