I don't actually run 4GB of RAM in any of my intel systems, so I can't comment from experience, however my suspicion would be the overhead introduced from PAE, which (at least on older kernels) requires some processing overhead to utilise. Are you able to try a 64-bit install to determine if this is the case? Regards, Tim Allingham Email:[EMAIL PROTECTED]
