2) Message boards : Number crunching : R9 285 (Message 64204) Posted 30 Dec 2015 by nanoprobe Post: Just received an R9 285 as an RMA replacement for an R9 270X. For some reason I can't get any tasks for it from MW. Runs POEM fine and my 7970 receives work. Is this card somehow not supported at MW? It does have DP capabilities.

I've just started giving Linux a try and can't seem to get this driver thing going. Thanks! (I'm sure a face palm is coming)

7) Message boards : Number crunching : Throttling GPU performance (Message 55162) Posted 17 Jul 2012 by nanoprobe Post: There are many threads here that GPUs are not getting enough work. Well I have kind of the opposite problem. Up to now I have used my HD4850 to crunch Moo, the card's fan would rev to about 10k rpm, which I cannot hear too much (or I've gotten used to), temp to 90°C. I actived GPU on MW recently, and now the fan has to spin to 14k rpm to maintain 108°C. In both cases the GPU load is reported to 100%, so I guess MW is using more of it. Now I can clearly hear the fan, the case's fans have to blow more air too, so it's all quite noisy when MW runs. I am a little worried of the temp level too. -> Is it possible to throttle down the GPU calculations? Not cycling, that kind of noise is even worse. I use an app_info file to throttle back my GPU when running MW. I'm at work now but I'll post it for you when I get home this evening. And FWIW I agree with Link. Running your card @ 100+ will probably kill it quickly

Here's the message log. 6/16/2012 10:03:38 AM \| Milkyway@Home \| work fetch resumed by user 6/16/2012 10:03:40 AM \| Milkyway@Home \| update requested by user 6/16/2012 10:03:45 AM \| Milkyway@Home \| Sending scheduler request: Requested by user. 6/16/2012 10:03:45 AM \| Milkyway@Home \| Not reporting or requesting tasks 6/16/2012 10:03:46 AM \| Milkyway@Home \| Scheduler request completed Tried a reset, didn't help. NM: Got it working. FWIW I still find that the 1.02 app causes my kill-a-watt meter to fluctuate by as much as 60 watts on 64 bit and 25 watts on 32 bit while I never noticed the 0.82 app fluctuate by more than 5 watts.
12) Message boards : News : testing work generation with 'ps_separation_14_2s_null_3' (Message 54788) Posted 15 Jun 2012 by nanoprobe Post: I just tried a couple of WU on a 5870 I acquired. Both ran to 100% and then went computation error. New/old problem again? Are you still using the v0.82 CAL app? The current WUs seem to be incompatible with it on 64-bit systems, but your GPU is OpenCL capable, so you could try that. I've stuck with the 0.82 because the later ones caused the GPU usage and power draw to be all over the place which I was not comfortable with. Even with an app_info to try and control GPU% didn't help. I may try the later app but I hope they can solve this 64 bit issue.

16) Message boards : Number crunching : Buy AMD Bulldozer or Intel Sandy Bridge for crunching BOINC? (Message 53242) Posted 17 Feb 2012 by nanoprobe Post: Good choice IMHO. Not only is Bulldozer slower, its' power draw is considerably higher.
17) Message boards : Number crunching : HIGH CPU USAGE with new 1.02 OpenCL tasks (Message 53241) Posted 17 Feb 2012 by nanoprobe Post: FWIW I had issues with 1.02 on all 3 of my 5830s on 3 different machines. I had to switch back to .82 to get things running smoothly again. I'm not currently running M@H so I don't know if the .82 app will still work. If it doesn't then I will not be able to run M@H on my current hardware.

20) Message boards : News : Separation updated to 1.00 (Message 53107) Posted 12 Feb 2012 by nanoprobe Post: What command would be added to the the app-info file to throttle back GPU usage? It's currently at 99% and I'd like to pull it back to 80-85%. Win7 64 bit. Radeon 5830. With the new app you don't need the app_info-file to control GPU load - it's now only necessary if you want to run multiple instances on one GPU. If you want to use it anyway the command line parameter apparently wasn't changed from the old app: --gpu-target-frequency XX Raising XX lessens the GPU load and increases the run time (default is now 60). With the new app it's easier controlled in the Milkyway@home preferences: Frequency (in Hz) that should try to complete individual work chunks For some reason the frequency setting in the M@H preferences is ignored. The GPU runs @ 99% no matter what the setting. I tried a target frequency in the app-info file with separation 1.02 and it caused the GPU frequency and power draw to be all over the place. Had to switch back to 0.82 to get things running smoothly again. Only thing I can figure is it must be some kind of a hardware thing on my setup.
