two tasks running, boinc seeing dual core?

The PC i have running boinc for seti on is an HP mini 210 which I know is not much, but anyway. My processor is a single core Atom 1.6ghz. Where do I make a change in boinc so it only handlss one workunit\ task at a time? I would see more units done in less time rather than two at a time taking twice as long. I know it's the same result, but it's taking down my daily average. Boinc has also crashed my laptop a few times as well and I wonder if the doube units has something to do with it? Suggestions for making the change in boinc would be nice.
