x301 memory remapping

[jamaicada]

Hello!
How can I use all 4Gb of memory without memory remapping in BIOS? There is no such option.
Windows 7 32bit shows only 2.96. Is there any workaround?
GM45 chipset supports up to 8gb. It's only Lenovo limitation?

It's a 32bit OS limitation. Run Win 7 64 bit and you'll use all of your RAM.

My x301 w/ 2 x 2gb sticks shows 3992mb total usable space on Windows 7 64bit. I think the intel 4500 graphics takes some for video memory.
