Just started boincing today for seti. Set general preferenced to various cpu percentages down to 10%, and seti preferences to various resource percentages down to 10%.

However, when I let it run it immediately maxes out my CPUs.

I also connected to Predictor@ home, and the same thing happens.

I'm often guilty of operator error, but this time I don't think it's me.

Any suggestions?

It's STILL you. :)
The "10%" thing works by running flat out for 1 second, then stopping for 9 seconds. (Or a similar proportion. e.g. milliseconds.) So what you're seeing is the time it's running, which is at 100%.

So... why wouldn't the cpu usage drop back to around 5% for nine seconds then back up for one?

Most computers should be able to run project workunits at 100% CPU without a problem. The main exception is that some laptops will overheat at 100% and may need to have the % reduced. Sometimes just slightly raising the whole laptop above the tabletop will be sufficient to solve the problem. Many laptops have less powerful cooling than desktops.

If your computer can only run SETI or any other project's workunits at 10% of the normal speed, I wonder whether you have an overheating problem on a desktop that should be addressed before you run workunits from any project.

You might like to download Everest or Speedfan which you can try as freebies to diagnose your CPU temperature.

After you changed the % in your preferences, did you click the Update button in boinc manager to implement the change?

It's not that the machine is heating up. It's that my settings for cpu time seem to be ignored by the core client. No matter what I set the preferences at, boinc runs the cpu usage to 100%.

What OS?
What BOINC version?

Per the author of Speedfan, it's made such that on certain laptop it only works as monitor and does not interfere with the laptop's CPU/Fan control. It throughroly ignore Speedfan and runs 100% on 2 cores at runs 63/66 C if sitting on a table.

I'm not sure about the BOINC control as it is to either run 100% or stand still and alternate that to arrive at an average. 10% would mean 1 second run, 9 seconds pause in the present throttle design.

If u used 5.10.x, even for testing, you might have created unwittingly an global_prefs_override file, where 100% might have gotten stuck in. Any setting in the override file causes settings on the web profiles to be ignored.
