While I'm thinking of it.

While I'm thinking of it. Has anyone run this on a card with 256mb of vram on it?

Does it run / error out / just not get work?

I may throw an old 8800gt 256mb into the 2nd pci-e slot on my nv rig.

Im glad I seen the comment

Im glad I seen the comment about setting the task to real time.
I am running a GTX570 and the first task I got, I didnt do a thing to it, and it was running the GPU at around 2 to 6 percent, with cpu at 20 percent. windows 7 had it as low priority and it took nearly 14 hours to complete.

I got a new task, which has the same 'estimated to complete' time on it as well, but changed the priority in task mangler to real time. Now the GPU is running in the low 30's percent utilization and the processor still 20 percent but, the task looks like it will complete in about an hour now.

That is an insane difference. Hopefully they will get it tweaked in, Id love to see what this thing can do with the GPU running in the 90's.

Also FWIW I have the card wound out as well and it's running very smoothly on this task.

Hope this info helps.

Both of my cards are reporting between 270 and 360 MB of memory usage.

Yeah, I checked myself since posting and noticed that.

I may pop the 8800 in and hope it doesn't try to run tasks on it. I could use that card on SETI if the app will not try to run on it. But I'm not sure if the BOINC Manager is smart enough to not try and run it on both even if it won't run on one of them.

I have changed the BOINC

I have changed the BOINC setting to 50% usage on both of my PCs. The Q6600 was totally starving because it was running 4 S5GC and 4 BRP3 units at the same time. I think the 0.2 CPU setting is a little bit to optimistic. On my E8400 and with a GTX460 the BRB3 app utilize 20% of the Dualcore (->0.4 CPUs). My Q6600 with 2x9800GX2 needs 40% of the Cores for the BRP3 (->0.4 CPUs/wu).
But still, really nice improvement.
So now only BOINC has to learn how to do mathematics. (4!=1+1+1+1+0.2+0.2+0.2+0.2)

RE: Exit BOINC fully and

Quote:

Exit BOINC fully and restart it. Don't just exit BOINC Manager and restart that, as the underlying client will perfectly run without the GUI.

BOINC Manager->File->Exit, check "Stop running science applications when exiting manager"->OK. Then restart everything through Start->Programs->BOINC->BOINC Manager.

It's OK now. Thx

Without setting the priority

Without setting the priority i have:
CPU: 3%
GPU: ~20%
WU-Duration: 2.5-3.5h

With setting the priority to realtime i have:
CPU: 20%
GPU: 70%
WU-Duration: ~1.5h

8800GTS 512, WinXP, Boinc 6.10.58 and two other S5CGE running.

WOW ! Just altered mine to

WOW ! Just altered mine to realtime for BRPS WU as mine were taking over ten hours... with or without Hyperthreading enabled.

Now seeing 56% utilisation of the GPU !

Here's some results from my

Here's some results from my home rig - Phenom X6 1055t + 8800GT 512MB.

Without changing the BOINC setting (100% usage):
- running 6 S5GC cpu + 1 BRP3 CUDA
- CPU usage on CUDA unit ~9-10%
- GPU usage ~6-7% :(
I tried changing the priority but with no success.

With BOINC setting changed to 90% usage:
- running 5 S5GC cpu + 1 BRP3 CUDA
- CPU usage on CUDA unit ~50%
- GPU usage ~60% :)

One other problem I do

One other problem I do notice, when putting einstein at real time, the GPU loads up however as soon as the task is over and it releases, the video card's parameters get reset back to stone age settings.

My GPU normally would run say around 700 mhz core clock freq as a default. I have it tweaked in the 900's now, however, irregardless, when the einstein task finishes, the card resets way down to a freq of like 150 mhz and the other settings drop down as well upon release. I have to manually go into the settings and set them back up again.

Needless to say, at these speeds I might as well break out my 10 year old obsidian onyx card and P3 and have at :D

Is there any settings or something I can possibly do to keep einstein from dropping the system like that when it exits the task or is this something that is still under development?

Thank you and Merry Christmas, Happy Hanakuh, or whatever holidays you do or do not celebrate.
