need help! low PPD with i7 875K

post #1 of 25
Thread Starter 
i have a damn low PPD with my OC'ed i7 875K
score is (says HFM.NET) 900, while my GPU is getting 7.5k PPD
i have -smp prefix incase you wanted to know

need a fix for this ppl

t.i.a.

EDIT: HT is off and i tried with and without bigadv, but same score, little bit over the 900

you're running with -smp and no bigadv, you should definitely be higher than that. Are you giving HFM.NET time to calculate the score? Sometimes it takes a few frames/percent to do that, if I recall. I also thought a GTX 285 SC should get more than 7.5k PPD? Maybe it has been awhile, but don't the GTX 260's still get about 6-7k PPD?

i underclocked it a bit cuz its dying, gives me a black screen and stays that way
underclocking it a bit fixes that problem

also i found out that i clicked on toggle bonus PPD/credit calculation in the View tab
gives me a score of 4800-ish, dont know if its a good score for a i7 875K

Ahh that makes sense. What unit are you currently folding, and are you currently running on all 8 cores with or without bigadv?

4 cores without bigadv
what unit? cpu and gpu at the same time (if that is what you mean)
post #6 of 25
4 cores @ 4Ghz? And you're getting 4.8k PPD?

Have you got HFM installed? If so, scroll to the "Project" column, and tell us what number Project you're Folding.

Ok, P6702 gives lower PPD than many WUs, and a quad @ 4Ghz would usually give 9-10k PPD.

It's possible a mixture of a few factors; perhaps the client had a bit of downtime when setting it up, or there were a few programs running taking CPU power away for a while during the WU.

At any rate, leave it as is for now, and check the PPD as the next WU comes in.

Since you mentioned that downclocking fixes instability issues, you're problem may be related to your OC.
