CPU PPD drops when folding on GPU

post #1 of 9
Thread Starter 
When my GPUs fold they make my CPU PPD drop to around 30k, when i turn the GPU clients off my CPU PPD shoots up to around 60k. Is this right?

I'd be gutted if this was the norm as it would be a waste of time folding on my GPUs. My GPUs aren't in SLI if thats any help.

Would it be better if i just folded on 1 card?

You're just folding on those 2 460's?

That seems like a massive drop in points for 2 Fermis.

How much does your TPF increase on the CPU folding?

(SLI doesn't have any effect; it's usually better to leave it un-SLI'ed to avoid any potential folding issues )

Yer just the 460s, ummm TPF is 24 mins atm. I've just closed one of the clients for the 460s to see if that makes a difference.

I'll keep an eye to see if the TPF changes.

When they're all running, look at task manager (ctrl+shift+esc ) and see what percentage of CPU time each core is taking up.

You'll be looking for the ones called FahCore_xx.exe

CPU usage is flat out 100% and FahCore_a5.exe is 97/98%

EDIT: Just read through an old thread and I changed my flag to -smp 11 to see if that makes a difference.

-SMP 11 will do the trick. Your cpu PPD will drop a few thousand but nothing crazy.
