order provided in the table, referring to the memory card diagram for location of sockets.
2. When one or more pairs of 2GB RDIMMs are installed, the maximum number of RDIMMs supported is 20.
Notes:
1) Performance is optimized by balancing the amount of memory between ports.
2) In order to enable memory mirroring during BIOS set-up, the same memory configuration must be installed in
each port (memory mirroring reduces the amount of memory available to the operating system by half).
