TERRIBLE ppd on a project

Postby cyclometric » Sat Feb 13, 2010 1:51 pm

Hi,

I'm running GPU2 folding on a GTX260 216 superclocked, settings are: Core 702, Shader 1513, Memory 1130, driver version is 196.21, cudart in the folding folder is 6.14.11.2030, dated 11/18/2009. I had just finished a 353 Credit WU with over 9000 ppd, when this WU loads, Project 3469, and I am getting 1550 ppd. Physx is disabled, though I think it was enabled when the WU started, because I was trying to test automatic fan control running FurMark, and forgot to turn if it off when I restarted folding, and by the time I realized it and turned it off, this new WU had started. Could that be the issue?

Cuz 1550 ppd is hoorrrrible, of course, for this card.

Anyone know what I can do?

Thanks,

first of all shut down folding on that card then restart if that doesn't work reboot your system and restart

What were you trying to achieve with the fan and how? If the fan is still running auto this could be heat

The PPD will probably pick up after you've left FurMark off for a while. It was probably just tying up the GPU cycles, and preventing Folding from using them.

When I encode some videos, I've seen my GTX260 hit lovely numbers like 190 PPD. (Which it is doing right now, as I am encoding some files for DVD use) As soon as the program finishes, my PPD returns to normal.

I did. Restarted the folding process, that made no difference, and rebooted machine, made no difference.

Heat is more than fine, I just wanted to have the BIOS adjust the fan speed, instead of running either RivaTuner or counting on EVGA Precision to do it (manually). The BIOS mod worked out fine. Heat is completely under control. In fanct, currently it's folding, finally at 98% of the %^@#^@ workunit, and temp is 61. Read on. . .

I had left Furmark for long enough, before I started folding again, that the temp had gone back down in to the mid 50's. And, the GPU load was 0% when the folding started. No Furmark remnants in memory.

That's another weird thing about this WU -- normally, on solid WUs where I'm getting 6000+ PPDs, the GPU usage is up around 98%, but on this one, it goes from 53% to 83% on average. Never 90%, and usually down well below 80%. I do sometimes do gaming, encode video, etc. while folding, and then the folding number goes down to like 5500 ppd, or even 5000. But this WU has been 1500 the entire way through.

it seems to be normal for this project - the more powerful the card, the less PPD it gets. There is another discussion here http://foldingforum.org/viewtopic.php?f=52&t=13419

That's a huge relief, thank you!!

& btw, just to prove it's not "me" or my card, it's on to the next WU, Project 5783, credit is 783 and it's outputting 7350 ppd. Phew! :e)

I got same problem!

My OC'd GTX275 getting less PPD than stock 9800GTX+!!!
But GPU Load seems normal (99%)...

yeah but at least you guys and all the folks on that thread with higher end cards have only had drops of 20-25% or so. My card for whatever cockamamie reason, decided to drop to just 20% of its normal output! What the frick! :egeek:

Did you check your clocks while running this slow WU ? The card might have not switched into 3D clocks ...

Yeah, I keep GPU-z open so I can monitor temps (though not so much doing it now, letting EVGA Precision put temps/fan% in tray, since fan control is done via the VGA bios) -- and it was on my OC setting the entire time. I had manually set them in Precision. I don't know what's up with F@H these days, though, it's wacky. Later in the day I was running another 3469 and I think I was getting 5500, much more acceptable, and currently I'm between 9K & 7.5K, so it all works out in the wash I guess. :mrgreen:
