[Leaplist] Only seeing 3G memory

[Gray Frost]

I hear what you are saying about motherboards and chipsets not able to read
more than 4 gig but this one is advertised and reviewed as having that
capability.

This is my uname -a

[root at localhost ~]# uname -a
Linux localhost.localdomain 2.6.25-14.fc9.x86_64 #1 SMP Thu May 1 06:06:21
EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
