I have a new rig with an i5 2500k overclocked to 4.8GHz.
It doesn't have a GPU yet, so I'm going to let it do some Folding at Home. I installed the latest Folding at Home client, but in Task Manager, it only shows one process – and that process never exceeds 25%.
Why is it not using 100% of my CPU power? I have four cores available. I made sure that 'Do not lock cores to specific CPU' was ticked in the advanced configuration of the client.
Task manager shows it is using all 4 cores but overall the limit is 25%. – baobeithebaobei – 2012-03-09T12:06:49.933
Just because a process is set to run on all cores (keyword affinity), doesn't mean it'll be able utilize all of them. – Der Hochstapler – 2012-03-09T12:53:59.797
