View Full Version : Current Hardware: Reaching Max PPD
Hey folks! Need some nub assistance. :chair:
Question about some of my folding gear, and what I'm getting for PPD via FAHMON:
(FAHMON is set to calculate PPD from the last 3 frames, rolling)
Folding rig: CPU (Q9650 @ 3Ghz)
-smp -advmethods -bigadv
Set for 80% in the config
400/ppd -- This seems off, not sure wtf the issue is :bang head
Folding rig: GPU1 (GTX 460 SC)
-gpu 0
~9.6k/ppd -- All good, happy w/this throughput
Folding rig: GPU2 (GTX 460 SC)
-gpu 1
~9.6k/ppd -- All good, happy w/this throughput
Main rig: CPU (i5-655k @ 4Ghz)
-smp -advmethods -bigadv
Set for 75% in the config
~850ppd -- Shouldn't this be higher? :shrug:
Any ideas, thoughts, feedback? :salute:
:comp:
PS -- regarding the 80% set for CPU use on the folding rig: It's still using 100% utilization, which is fine, but I wanted to allow 'slack' in case the PSUs needed CPU cycles for their folding. Should I bump this up higher?

Try using HFM.NET and see if you get the same figures. I think FAHmon doesn't include bonus points.
I'll post my settings from my q9550 and 930 when I get home tonight for comparison.
Ah, good to know. I've got it installed, will check and post shortly.
Edit:
Yup, you were dead on. Here's after checking with Hmf.net:
Folding rig CPU = 3.3k/ppd
Gaming rig CPU = 3.4k/ppd
Roughly ~27k/ppd production for team Jmtyra...er...Team 32
Thank you _s3v3n_!! :D

You might also try without the bigadv and see. It'll probably be close if not slightly higher without it. :)

Your "Folding Rig" can't do -bigadv... it doesn't have 8 cores so I'd just drop that from the command line.
You should set all your CPU clients to 100% and forget the 75%~80% stuff. Just make sure your GPU clients are set for 'low' (console) or 'slightly higher' (systray) priority.
btw- HFM.NET is home baked right here at Team 32 by yours truly. There is a thread link in my sig if you ever have specific questions and also a Google Group that I monitor almost daily, you can find me quicker using the Google Group. Enjoy! :)
The way the bonus points work, a 20% reduction in cpu utilization is at least a 30% reduction in ppd. FAH is good at releasing cpu resources so there isn't, as harlam said, a need to run lower than 100%.

OH! Updating now...

Yup! For some reason I thought the Q9650 did HT, but I am incorrect. /sigh

Oh...okie-dokie! I wasn't sure if it'd affect the GPU cycles, and wanted to play it safe. LOL, someone on the OC forums playing things "safe". That's funny. :clap:

Really?!? I *knew* there was a reason it seemed like an epic program. My hats off to you, it's a nice program. I like! :salute:

ACK! I was basically shooting myself in the foot it seems.
Thanks for the feedback guys and gals. :thup: Now I've got updates to make...
After making the latest changes, and using (the wonderful!) Hfm.Net application, it appears that the gaming rig is now pushing ~6k/ppd. Daddy's happy. ^.^
Well Son of a @)#*$(&). Started a GPU3 client on my gaming rig, and while it is in the ~2k/ppd range, it's eating enough CPU cycles to bring my gaming rig down to ~300/ppd from it's prior ~6k/ppd. Not happy. It's an ATI card, and I guess it's taking something extra or whatever to do the crunching.
Any-who, I'm terminating the GPU client as it's actually less overall ppd and about ~100w less energy.
/sigh

There are environment variables you can set to make the ATI client take much less CPU resources. (I run Nvidia, so I don't keep track, but a forum search should find them for you.)

My predicament is the opposite. When running the CPU alongside the GPU clients, it get's strangled and doesn't complete bigadv's fast enough to get bonus points. Running by itself it does fine but it's a matter of 20,000 ppd with CPU alone (bigadv) versus 50,000 ppd with GPUs and regular smp. Needless to say no more bigadv's. Oh well.

Yup, found it, but based on ChasR's feedback (http://www.overclockers.com/forums/showpost.php?p=6469889&postcount=8) I think I'll a) say "screw it" and leave the card inactive and b) always be buying nvidia cards simply for the folding gain. ;)

What GPU are you running it on? Duh. Read his sig, Jmtyra. /facepalm
Well, I agree that sucks, but you've got 3 of those puppies wanting CPU attention. :shrug:
And, indeed sir, fold on! :salute:
