Adding and Replacing Parts

Fully buffered DDR2 memory modules can also be installed in pairs of two; in 

this case, the computer will continue to operate, but with a slight reduction 

in performance. The pairs must be matched in size, rank, and organization.
Install memory modules in order of their labels on the system board; matched 

sets of four should be installed first into DIMM slots 1-4 and then into 

DIMM slots 5-8 on the system board. Pairs of memory should be first 

installed into slots DIMM_1, and DIMM_2, then DIMM_3 and DIMM_4, 

and so on.

Do not install non-ECC or unbuffered memory modules. Doing so may 

cause the computer not to boot.

DIMM slots 1-4 have white latches for easy identification. DIMM slot 5-8 

have black latches.

This computer supports a maximum of 32 GB of memory when eight 4-GB 

DIMMs are installed. Current 32-bit operating systems, such as Microsoft

®

 

Windows

 XP and Widnows™ Vista, can use a maximum of 4 GB of address 

space; however, the amount of memory available to the operating system is
