Any reason why my processing chip, a dual quad duo, only runs BOINC in one of its four quads, i.e., at 25% maximum (so says task manager)?

My preferences are set to allow 80%.

Am running XP-SP3 on a Megabyte Mother Board, with an Intel Chip.

What happens if you allow 100%?

What version of Boinc? Older versions use a different preference:

On multiprocessors, use at most 4 processors
(used on Boinc 5.x.x)

On multiprocessors, use at most 100% of the processors
Enforced by version 6.1+

When you say only one of its four quads, does that mean you have 4 Quad Processors, as in, 16 cores?

Problem seems to have gone away when I added Einstein to my project list (which indicates that is supports quads).

New problem. My mouse sometimes slows to a crawl, actually it moves after I stop moving it--freaky. Seems to be associated with the BOINC manager. Unlss there is an instant reply, I'll have to gather up some additional information for member analysis. I'm a new user and appreciate the assistance.

What project was the initial problem on?

Did you have enough tasks?

Do you have an Nvidia videocard?
Will you answer any questions?
