Virtual Memory settings w/ Tons-O-RAM

Hey all,
I'm going thru my notes from SWW, and I found something from GregJ's Bootcamp on Sunday. He said something about the usual '2x RAM'rule not applying to large values of RAM....that's all I've got.
Did anyone attend and get more than that? What do you use w/ 4GBRAM? What do you use w/ more than 4GB? What is working well?
Just curious what the latest is. We just deployed SW2008 and arestill running WinXP32, new Dell 3400 workstations w/ 4GB RAM. I'mhoping to deploy SW2009 around July and go to Vista 64 since wework with large assy.

Thanks! Nice to see everyone at SWW!SolidworksAdministration
