I'm looking to install the software on my new computer, however I'm wondering if it's possible for the software to glitch and give bad results back to WCG. Is all of the data run twice and checked? The reason I ask this is because not only am I on vista, but I'm also on an overclocked system. But running WCG would rock because I'm on a dual core extreme edition running 4 ghz per core, 4 megs l2 cache =D

Three times!
If you install BOINC, you will not only be able to take advantage of your dual cores, you will also be able to track the progress of your results after you upload them. You will see them being validated, and you will be able to spot errors early on. People who return unusual numbers of errors have their work supply limited by WCG, and are also (I think) sent an informative email. |

Wow that's good to know! You can expect to see my results jump a bit now. I just moved from a 2.4ghz amd to this beast =D Does BOINC give the uber 1337 screen saver? Thanks for such a fast response by the way!

Ok well regardless to that question, is it normal for boinc to show something like this when cpu usage is throttled?

Yes that's normal. The throttle doesn't limit CPU usage to a certain steady percentage. It's more like an on/off switch. If you set it to 80%, it'll go 4 seconds on, 1 second off.
----------------------------------------Check your result status on a daily basis. If you start seeing numerous "invalid" results, it's likely your machine is not stable and needs to be tweaked.  |

I'm not very impressed with the BOINC throttle. The WCG solution works far better, but it relies on additional code in the science application.

Last WCG agent I used didn't have that functionality. Does it work any better? Which agent do you guys prefer?

Threadmaster and BES are the magical words for windows, CPU-limiter for Linux Check your result status on a daily basis.

Check your result status on a daily basis. If you start seeing numerous "invalid" results, it's likely your machine is not stable and needs to be tweaked. And here the effects just described on BOINC Dev for 5.8 and the new throttle. Have bolded the important advice: Observation: Running 5.8.8 (Seti@Home and Einstein@Home) on an IBM Tablet PC running Windows XP...my screen saver sort of flashes on and off, staying on for only a 1/2 second...then stays off for a few seconds, then flashes again...and keeps this up. Screen saver never stays on as it used to. Should I uninstall 5.8.8 and use an older version or is this a Tablet PC problem? The Reply: When you are throttling the CPU through BOINC, what it does is pause the crunching, then continue the crunching. When a result is paused it won't show the graphics/screen saver. So when you're using the throttling, don't use the screen saver. To answer soGGy: It's personal. The throttle works for UD(WCG) Agent and u can change it almost in real time, BUT UD only uses 1 core. If multicore (as many as u can squeeze in a box), BOINC is better and with the aforementioned magical word "Threadmaster", superb in throttling. Not for the novice in set up. For those, use BES. Added: The screensaver problem in combination with the throttle is fixed in version 5.8.11

Thanks for answering my question. Any chance they'll be changing the throttle set up anytime soon? I may not have to throttle it, once I get some more testing with temps in on my comp and I feel comfortable running it at 100% 24x7 I'll let it do it's thing. But between vista and an overclock I don't want to push it just yet.
