v The optional DIMMs that are available for the blade server are 512 MB, 1 GB, 2 GB, and 4 GB. Depending on the memory configuration that is set in the Configuration/Setup Utility program, the blade server can support a minimum of 1 GB and a maximum of 24 GB of system memory on the system board. v When you install memory, you must install a pair of matched DIMMs. Some blade server models come with one DIMM installed in DIMM slot 1. In this case, you must order and install a second matched DIMM in DIMM slot 2. Install the DIMMs in the order shown in the following table. Table 2.
