I have 4GB of RAM in a Precision 670. Aida32 shows 2 sticks of 1GB RAM and 4 of 512MB. But System Information and Computer Management show that the computer has only 3GB of RAM. Setup (F2) also shows 4GB
DIMM 1 1GB ECC Rank 2 Registered X8
DIMM 2 1GB ECC Rank 2 Registered X8
DIMM 3 512MB ECC Rank 1 Registered X8
DIMM 4 thru 6 - same as DIMM 3
Is there any way to make sure that all 4GB of RAM is being utilized? Thanks.
