No, each CPU can access the full memory.

Sounds about right for that late night seti-crunching. 8-)

Am I right in that the current 512M ram will be shared on two cpus,
effectively making it two 256M ram computers, and that I would also
benefit from adding more ram, like 1GB, so that each cpu has access
to 512M each?

Thx for the info!
