I am not sure it is a bug or not but I checked using my processor and I see it's not effective 50% as I changed in preferences. BOINC is all the time jumping from 50 to 100%. I am not sure is a mistake with EIST, because when is less used it's change to 2400 Mhz, and high 3800Mhz. Look screen:

That's the way BOINC currently handles CPU utilization settings; if you were to average out the spiking you are seeing, it should be roughly 50%.

On BOINC forums they explained: http://boincfaq.mundayweb.com/index.php?language=1&view=45

Its little bit confusing but what to do:

100%: it runs all the time.
90%: 9 second run, 1 second idle.
80%: 4 second run, 1 second idle.
70%: 3 second run, 1 second idle, 2 second run, 1 second idle, 3 second run, etc.
60%: 1 second run, 1 second idle, 2 second run, 1 second idle, 1 second run, etc.
50%: 1 second run, 1 second idle, 1 second run, 1 second idle, etc.
40%: 1 second run, 1 second idle, 1 second run, 2 seconds idle, 1 second run, etc.
30%: 1 second run, 1 second idle, 1 second run, 3 seconds idle, 1 second run, 2 seconds idle, etc.
20%: 1 second run, 4 seconds idle, 1 second run, 4 seconds idle, etc.
10%: 1 second run, 9 seconds idle.
0%: It's paused.
