	Which preferences are used by Boinc? I see a set of computing preferences here on the website and also "Boinc Manager Preferences" within the manager. My issue seems no matter how far I ramp down CPU usage SETI application still keeps spiking CPU to 100% as viewed in the task manager. Thanks In Advance! Arnold R.

	the reason you see that spike is that you are not using those CPU cycles. BOINC/seti backs off when other programs are running. So seeing 100% CPU usage from Seti is common when your CPU is idle ____________ Proud member of TSWB. End terrorism by building a school

The Boinc preferences override the web settings. Boinc is designed to work across several OS so it can't do a smooth throttling of the CPU. This feature is design to reduce heat not to directly reduce the load of BOINC on the CPU. example: At 90% it uses the CPU free cycles for 9 sec and turn off for 1 sec. Your account is hidden so I can't tell what OS your using. One program I've seen mentioned on the board is TThrottle. It may be better for what you are trying to do. ____________ Questions? Answers are in the "Unofficial" BOINC Wiki. Boinc V7.0.27 Win7 i5 3.33G 4GB, GTX470

	I'm running Windows XP Pro in this case on a Dell Dimension 2500 (fairly old machine). If for example I limit CPU usage to 50% I will still see spikes to 100% in the task manager? Its not really a big deal more curiosity then anything else as the machine is only running SETI & my weather program (WUHU), occasionally my son will use it to play a game. Thanks Again Arnold R.

At 50%, it will run 100% for 1 second and 0% for 1 second. This helps dramatically with laptop cooling (even 75% CPU usage which would be 3 on and 1 off). The BOINC polling loop runs once per second, and it is during that polling loop that the decision is made whether to run the computations the following second or not. ____________ BOINC WIKI
