W7 x64 on AMD 64 X2 4800+ no memory display

W7 x64 on AMD 64 X2 4800+ no memory display in System Control Panel.
Board has 4x1GB DIMMs - no memory amount shows. Task manager shows total memory of 3839?
Strange? Anyone else seeing this issue? System seems to be running OK. System performance shows 5.2 for memory and 5.2 overall. System type does show 64-bit OS.

Could you please take a screenshot of your system properties and post it? Thanks
