Does anyone know why PCs running XPPro with 3 GB RAM and the 3 gig switch have sluggish performance when approaching 2GB? It's great when you have the memory and the switch but the only thing it seems to buy you is keeping Pro from crashing (windows killing it at the 2GB level) You really don't seem to gain any performance from adding the switch. Any ideas as to why this is? Can anything be done to improve performance at this high mem level? Sorry for all the posts today, I thought I'd be more likely to get an answer for each of my questions if I posted them separately. Thanks, Mike
