Multi GPU Folding (5x Nvidia) - Error starting Folding@Home - Page 6

post #51 of 55
no, PPD is calculated by Time per frame section, which each frame is 1% of the WU, and lower the TPF is the faster the WU gets completed meaning more WUs and more PPD. So the only way to increase your PPD is to overclock what ever your using to folder higher to crunch them numbers faster.

But on a side note tho I was able to use 2 cards foldering one a GTX460 and 9800 GT but instead of using the smp core count switch i just changed the % of cpu usage it would use. Im not sure if it really hurt or helped but I never noticed a large PPD drop or anything.

Ah right. I knew it wouldn't affect the actual PPD, I meant the reported PPD by HFM. Unless HFM only uses clock speed to generate PPD/ per MHz column.

How did you change from core count to % based?

well as i said above tho is that PPD is calculated by the Time per frame. That is how ALL points are calculated, it also helps estimated how much PPD you can do on a WU just by doing only about 3-5frames but more the frames you do the more accurate the PPD.

And yes it only uses the mhz to calculate how many pts you are making per mhz,kind of like a efficiency rating to max your PPD really.

.In the console you have to use the -config switch like in the provided picture. And go into the advanced options and it will ask you how much of the CPU you want to utilize for the client. I currently use 95% for my single GTX570 right now tho with my Q6600 @ 3.6ghz.

But I changed my smp to use 3 cores and i have lost about 600 PPD with only about 80% cpu utilization with my cpu and gpu folding as of right now. And the gpu didnt change so I think this way is not the best to make the system completely loaded. But with you having what 5 gpus using the % might be better might not. Would just have to see how well both worth for your cpu since you got a 6core.

But not cram more crap in here for you tho using core count might be best since each gpu will prob use an estimate of 20% ± 2%. So we can guesstamate your 5 gpu will use around 1 full core just for the gpu clients them selves more or less. But if you change the priority of your gpu clients cores with the program SetPriority to normal and set the smp on idle, with the smp client using 100% cpu utilization you should be able to maximize your PPD that way. idk but its just a thought really.

SMP 6 dropped CPU usage to about 85% and it no longer crashes. I suppose once I get an aftermarket cooler I can OC and go back to SMP 7.
what i have found. when o/c my 460gtx. the more i had hte more voltage they all need to achieve the same o/c.

by themselves they only need. 985mv but when there all together running they need 1025mv to be stable at 851mhz

Ok quick recap. I decided to pull the 8800 GTS out of the system. This enabled me to space the GPUS out. I have the 4 single card with each 1 slot between them. This has dropped GPU temps to 80C @ 80%.

I then OC'ed all 4 cards.

This setup seems to be far more stable and the temperatures are management. Plus the sound output is far less.

Also, remote desktop connection is a PITA. It definitely is not conducive to setting up folding.

Thanks for the help everyone!
