[Windows 7] MultiGPU Guide - nVidia - Page 7  

post #61 of 427
That's nice to see. Just soem advice, using the protein viewer reduces folding performance, so you might want to think about closing that.

You can watch the progress with Fahmon.

Also, you can reduce the CPU usage of the GPU client with these environmental variables.

Your name will change in the next work unit and so will the team.
Keep that thing minimized at all times though to save resources and maximize performance.

I noticed that its performance was reduced a lot when I opened it so yeah, its closed for now! Thank you so much! I sure as hell hope that I'm finally part of something! Notice that this machine runs 24/7. Would you think its to hot to run the cores at 4.4 GHz @ 73°C 24/7? Do you recommend HT on?
post #64 of 427
73°C is above Intel's thermal specifications.
67.9°C is the safety limit for an i7 920 and it's definitely not recommended to run at such temperatures.

If I were you I'd stop stressing it right away and find a way to lower the temps; whether it's better cooling or lower voltage.

As of the HT question, yes, enable it and search for bigadv in the forums.

So the other day I took my monitor on a trip to use with a PS3, and my 4890 was folding when I unplugged it. It folded the entire time I was away without a single error. I think that if you start folding with a dummy plug or a monitor plugged into the GPU then it will keep folding without one plugged in, or at least it would appear that MY GPU could...

To be fair, I did downclock it from the "normal folding" 1035 to 1015 and increased the fan a few percent before I left, but still...

True, but you do only have one card; if the card is the primary GPU it doesn't need a dummy plug. Unless this is a different rig you're talking about?

Oh, sorry, I meant my friend's rig that I'm keeping for him for a while that has 2 4890 XXX Editions. He folds too (for a different team though) and I have it set up in my room next to my computer. I had the DVI input on my monitor plugged into my computer, and the D-Sub and HDMI on his computer. I unplugged all 3 of the GPUs when I left. None of the cards had errors the entire time (but my room was like 90 degrees when I got home).

I left the DVI to D-Sub adapter and the DVI to HDMI adapter on his computer though, is it possible that that acted as a dummy plug would? I wouldn't think so, but it's possible....

Sorry for being so vague. I guess I just assume that people know exactly what I'm talking about sometimes...

I don't think they would have acted as plugs (since we use a DVI-VGA adaptor for plugs anyway, but still need resistors).

Maybe it can continue to work on the WU only, then when trying to get a new one it'll errror out. Or maybe, in fact, it does only need the dummy plug to get started.

Do some tests!

Yeah, I'll try doing weird stuff with the plugs and GPUs and stuff and see how it works on his system... It's very possible that i just got extremely lucky though. That's been known to happen.


Edit: I can't do this until tonight when I get home though, so don't sit there waiting for me to respond!

Hey Bass, maybe you should put a note at the bottom of your guide mentioning that in Windows 7, if you add the -forcegpu nvidia_g80 flag, you don't actually need a dummy plug or need to extend the monitors. It makes SLI folding a bit more difficult (though still possible), but would be very handy for folding rigs.

And thanks for that information [CyGnus].
