Hi Im running bootcamp on my mac but I dont think im getting the most out of my RAM. When I check my system props in windows it states:

SYSTEM
Windows xp
home edition
SP2

COMPUTER
intel(R)Xeon(R) CPU
E5620 @ 2.40GHz
2.39 GHz, 1.86 GB RAM

however my system spec is

Lion
Two 2.4GHz Quad-Core Intel Xeon “Westmere” (8 cores)
6 GB (6 x 1 GB)
1TB 7200-rpm Serial ATA 3Gb/s hard drive
ATI Radeon HD 5770 1GB
One 18x SuperDrive

So my question is why do I only get 1.86 GB of RAM in windows? is this just the way it is?

Thanks
Graeme

Because 32bit windows cannot only access 4 gig, remove overhead from windows and what not, and you only get that much.

I'd go with 64bit windows 7, you'll be able to maximize the usage of your hardware.

Edit, for some reason 32bit windows xp only sees 2.25gig of ram even though you have 4gb. Then subtract over head and that leaves you with what you see.

Do you have the 64-bit or 32-bit edition of Windows?
Normally you should get at least 3.5 GB RAM in the 32-bit Windows version, though your use of six 1 GB sticks might limit you to less. Maybe use a 2 GB or a 4 GB module, or several?

64bit yes, windows xp 64bit no. At this point, I'd recommend going with x64 windows 7

Can I download windows 7 and just install it with out having to re format my whole mac, I gave windows 32 GB when I boot-camped initially so should it just work?
