Figure 3-1 DIMMs sockets on the x440 SMP Expansion Module
Key memory configuration rules:
Because the x440 uses
–512 MB DIMMs, part number 33L3324
–1 GB DIMMs, part number 31P8300
–2 GB DIMMs, part number 31P8840
Memory DIMMs of different sizes can be used in the same SMP Expansion Module, but all four DIMMs in a bank must be the same size.
If you want to install more than 32 GB of RAM, you must use two SMP Expansion Modules. This in turn means that a certain number of CPUs must also be installed. In Xeon
Four 512 MB or four 1 MB DIMMs are standard in the Xeon MP models, and the Xeon DP models have eight 512 MB DIMMs standard (see Table
