8gb memory installed - only 3.25gb usable Win7 64bit
8gb memory installed - only 3.25gb usable Win7 home premium 64bit. MSI MS-7358 mobo has no memory mapping facility. No on-board graphics. I have un-checked maximum memory in msconfig. Mobo states 8gb. Resmon shows 4gb reserved. All 4 x 2gb sticks are identical (crucial).
Any ideas where to go next?
