The title says most of it, and it's happened on two different boxes - only similarities are AMD64X2 CPU and running same ubuntu version, before and after.

For the record, I'm running AKV8 SSE2, but I don't think it's relevant.

Much more likely, as in 8.x, a power management setting limits cycles to 50% max, but I can't find where to disable the limiter.

and, no, powersaved isn't even installed.

Has anyone had the same problem and found a solution?

Edit: eeeeek! no I'm not running AKV8 any more, hold on, checking stuff...
Edit: AK_V8 and the right app_info.xml are in /var/lib/boinc-client/projects/setiathome.berkeley.edu/ but setiathome-enhanced is running. I'll try a reinstall tomorrow and see what happens.

Now the only reason I can see you would want to run Windows-whatever at home if you're not a complete lamer is to play games, and playing games is emphatically not good for RAC.

Hey..I play games on my main cruncher without suspending any work. In the longrun with 4 cores, I only lose about 3% of the crunching potential by doing so. I didn't actually run the math to figure out the percentage, but 5% seemed too high, so 3 sounds good. I only play games at the most about 2 hours a day, and whilst most of the "newer" games utilize multiple cores, they don't max the cores out, so it's not that detrimental to the crunching. In fact, if I have an MB running, after an hour and a half of playing a game, the ETA on any MB task only increases by about 5 minutes. I run seti/BOINC like it was intended..using the 'idle' power that I would not otherwise be using.

I was thinking more in terms of CUDA than CPU... ;)

The issue of DRM in Windows is an old one and was a major source of Longhorn-bashing.

And it IS an issue: "nothing that installing VLC couldn't solve"

But that's not especially DRM. When I get a new windows box at the office, I usually have to install, let's see, Firefox, VLC, Gimp, Ooo and a couple others to turn it into something not too annoying to use. And the list would definitely include Thunderbird if it could work with exchange. And I purely hate to see that AV icon in the tray.

That pretty much tells you what I run at home :)

This said, it's true DRM today is an non-issue for most - as in 95% - users, especially if you don't use WMP - which I would never do because it won't read my ogg-ripped CD's.

Now the only reason I can see you would want to run Windows-whatever at home if you're not a complete lamer is to play games, and playing games is emphatically not good for RAC.

Hi,

Am I correct in assuming there's no Linux package available as of now?

For the record, I run:
1xAMD64x2/4400 + 8400 / Ubuntu 8.10 / standard Ubuntu Boinc + AK_V8_linux64_sse3
1xAMD64x2/4850 + 8400 / Ubuntu 8.10 / standard Ubuntu Boinc + AK_V8_linux64_sse3

I'm planning on buying a better-but-cheap 100W-or-so GPU for the processing power for the 4400.

I could do some testing if it's useful, but I might need some hand-holding.
