Since PG is going in the crapper, has anyone had any luck running Moo on multiple GPUs? I tried it once, but it failed though i assume it's because i forgot to disable the GTX 460 and the 590s didn't like sharing the work load with it.

Not really sure about dual CUDAs on Moo! because I run my ATI there, but DiRT would have better credits for your big CUDA hogs anyway. ;) :D

Tell me, what is the DiRT of which you speak?

DistrRT@Home. I started calling it Dirt because its faster to type....... :P

Edit: Though I can see that DrPop is faster at the KB then I.

oh that! cool i'll give it a shot. been signed up with them for awhile anyway.

i think i'm gonna have severe clutter in my Tasks tab. My work load is set to 0.2 days, but these DiRT ( :p ) WUs are coming in at 7 secs apiece. it's gonna get crazy. How long do they actually take to run? Still have a wad of PG to finish up before Boinc gets to them.

heh...with your hog GPUs? It'll rip through 'em pretty quick alright. Depending on your bandwidth, it may actually take you longer to upload the WUs than to crunch them with your rig! :D Only thing is, make sure you have at least 1 CPU core that is reserved strictly for feeding the GPUs, because it'll need it! :cool:

10m 40s on gtx 460 @ stock speed

4m 55s on 590s OC'd 10%

waiting to see what kind of credits we're talking about here.

Good ones. With my GTX 460's O/Ced to 900, I'm at roughly 3.1 / sec, I think. Don’t look at my credits today as an average; things were messed up and I had to reset everything. I should be back in the game now, though.

2000 credits per task.

Just curious, what are the oc numbers?

I've got mine at 680/1360/1728 core/shader/mem.

I've pushed the core to the supposed maximum of 700, but the temps are higher than I want.

I've basically given up on OCing anything. Just seems to cause more problems than it's worth.
If I ever switch to water cooling, then that will be a much different story, but for now, stock speeds only.

I've been contemplating that as well. The temps go up and the noise as well with OC.
