v The system board contains four DIMM connectors and supports two-way memory
v The DIMM options that are available for your blade server are 256 MB, 512 MB,
v Your blade server comes with two DIMMs in the DIMM 3 (J2) and DIMM 4 (J6)
v When you install memory, you must install a pair of matched DIMMs.
