Boo-Yah! 8GB (2x4GB) works in pro.

The Pro Business (RNDP6000-100) has a CPU that doesn't have VT-x so you can't run 64-bit VMs using VirtualBox. You can use it as an ESXi datastore for 64-bit VMs though. 3rd party memory upgrades are not supported, neither is installing stuff like VirtualBox. CPU upgrades do void the warranty and not all work (can be incompatible or cause overheating etc.). If you want to try a CPU upgrade search for CPU upgrades that others have done). Instead of doing a CPU upgrade it would be much better to sell a Pro Business (RNDP6000-100) and get a Pro 6 (RNDP6000-200).

I see, you're referring to the E2160 native CPU - well I guess I'll have to decide whether I want to void my warranty to get the VT-x available with the Conroe 2.4G dualcore E6600 CPU...
decisions decisions... I've read else where in the forums that memory upgrades will not violate warranty if they pass tests and are done responsibly and properly. I kept my original 1Gb of RAM so that will always be available if I need to downgrade memory (thats easy, just take out 2 screws and click in and out memory modules with an antistatic wrist-strap in place) but I'm not going to tinker with a CPU and the RDNP6000-200 is a better idea for that indeed. I bet someone has gone with an E6600 (and said forget the warranty...) and made this Virtualbox and ESXi VM datastore both work though...

FYI:

this notes that the E6600 has VT-x... time to decide.. My Pro Business still has 4 more years of warranty...I dont think I want to lose that...

Good suggestion on the Pro 6 -- I tried 2x to order (order then reorder) a Pro 6 refurb from these guys when they CLEARLY showed stock (I screen-captured it 2x) :

but they are disreputable dirtb@gs and they never honor their prices nor availability for me (nor I suspect others too..) and I have a BBB complaint pending with them.
