Why such vast differences in PPD???

Hi Guys,

I've had no end of fun recently with this folding malarky, destroying power supplied/system hangs in the middle of the night causing 0 hourly entries.

Anyway back to topic subject.

I'm running Client V7 on this machine, but I've also got GPU Tracker V2 installed.
When I run Client V7 my 2600K @ 4.6 is showing a PPD of 3088
When I run GPU Tracker on the same processor I get a PPD of 25,000

Why are the figures so wildly different?
Are there some switches I can set within Client V7 that will up the PPD??

Cheers
Lee
 
Are you folding different WUs on the different clients? I was on a streak of bad WUs and was getting about that kind of PPD on my 930.

You can try the client-type advanced switch on the v7 client.
 
I had the same thing with WU's on my 2500k. PPD on my cpu used to tick away nicely at around 20/25k a day untill a few weeks ago when I was getting as low as 6/8k ppd. However I dont know if it was WU's or my settings.

I had been playing around with my 560 and my old 8800 GTS at the time to try get the old card going aswell. However when this failed I did a fresh driver installs and went back to just using my 560. But the Physx settings were set as auto, I had forgotten to manually adjust them. I went into my setting manually adjusted them back to use the card Not the CPU and my cpu PPD jumped back up to 15/18k PPD. Still lower than it was but a big improvement for a simple settings alteration.

Maybe worth checking how you have your system set?

When I get home from work I will get V2 and see if I get the same discrepancies. :)

What should the physx setting be set too?

With the physx settings you should have the options in the NVIDIA control panel to have it set automatically, to use the CPU or the GPU. If you have a multiple GPU system you will be able to select between the two.

When I was playing around with my settings I found setting the GPU to handle physx instead of leaving it on 'Auto' caused the CPU PPD to jump up considerably. With the GPU PPD staying pretty constant at around 15k PPD

Hope that helps :)
 
Seems like the rest of the team are getting all the pants WUs now and I've gotten out that rut at long last with 34k PPD out of some units (considering that's in Windoze and there's three machines getting that plus a pair of 430s... looking rather nice now).
 
ok im a little new to the folding, but my 5k PPD comp has dropped to 894 PPD, thats right 894 this a WU thing? or have i screwed something up??

I'm pretty sure that's a rather large WU as I remember having it a good few times and it took just over a day on a 1090T/ FX-8120 to complete. Brought in normal PPD though - probably only just scraping through the deadline so I'd recommend you use the 'max-packet-size' : 'small' flag on your client to avoid huge units.
