Gearin' up for some CHIMPIN! various questions

post #1 of 13
Thread Starter 
Edit: New question. Anyone have a problem with Chrome lowering GPU usage? I've been watching precision on my G15, and while I am browsing with chrome my GPU usage drops to ~90%. If I close it, it jumps right back up to 99%. It also stays at 99% if I use firefox 3.6 instead (drops to 90 while loading pages, but jumps back up afterward). I just can't figure out why this would be happening. That's a whole 9% of GPU that isn't folding! I don't see how that can't be impacting my PPD negatively. So ya, firefox for the CC, but still odd and just wondering if it happens to anyone else. Oh, and I have disabled all addons in chrome besides adblock plus.

__________________________________________________ _____________________________

Alright, I'm setting up for the Chimp Challenge after being out of folding for a while. I am in a tiny dorm room, and can't really sleep/study with a cap-squealing tornado under my desk However, the CC is worth it I've got a few questions, as a lot has changed in the time I have been dormant.

First, video drivers. I have had the 197.13 drivers for a while now, as they have worked fine and upgrading always seems to screw something up that I have to fix. Have the new version drivers upped the PPD at all? If it's a noticeable amount I will gladly upgrade, but if not I'll probably just wait until break when I have time to upgrade. My two GTX 275s pull ~ 8000-9000 PPD each with 666 core and 1512 shaders (ya, evil GPUs usually crash if I push higher than that ), with SMP at 1500-2000. I assume this is still considered decent PPD for my setup?

Which brings me to another matter, my 8400GS. I have heard of people folding on this card, but I have never had any luck. It just sits there for a while (0% load shown in EVGA precision), then throws an error (EARLY_UNIT_END) and gets another WU. Anyone know how to make this darn thing fold? I am currently using the FAH GPU Tracker V2 recommended by Zodac (AMAZING tool BTW, I always hated manually setting up multiple clients), but it did the same thing with the normal clients as well.

Also, GPU3. Is it advantageous to switch over to that now, or just wait? I read that the core is still in beta, so don't want to be dealing with a bunch of problems during the CC. I assume all I need to do to enable it is to check the GPU 3 box next to my cards in GPU Tracker?

Finally, should I set the -advmethods flag on all my clients? SMP always goes so slow anyway, I don't know if this would slow it down even more and finish fewer WUs during the CC.

Thanks for any help! Any more optimization ideas would be appreciated (already disabled aero and shot down a bunch of background applications). Feels good to get back to folding for a while, hopefully I can do more over the summer when my PC isn't right next to my bed.

No PPD increases with drivers; just a lot of crashing with 270.51.

Yeah, the low end 8 series GPUs are hit and miss; they'll either Fold or they won't, with most of them ending up not Folding after a few years. If it doesn't work right away at stock, assume it won't work. Not worth the hassle to be honest.

No need for GPU3 for you.

No -advmethods on SMP.

You might wanna enable Aero; I only got lag when I disabled it.

Awesome, thanks!

Something very odd just happened. My GS just went to 1%, but there is absolutely no load on it Guess I'll let it run and see what happens.

And ya, everything is very choppy without aero but I didn't know if it would help with PPD at all.

I checked the options before but didn't find anything, so assumed it didn't have anything like that. How would I go about disabling it? I tried the -disable-accelerated-compositing in the shortcut that I found by searching, but that just said nothing was found at that address when I tried to put it on the shortcut.

You sure you added it correctly? It's meant to be added the same way the -smp flag was/is added.
