To install a DIMM, complete the following steps:
1. Locate the DIMM connectors (see "Blade server connectors" on page 15).
2. If a DIMM filler or another memory module is already installed in the DIMM

channels 0 and 1. The spare channel is not available as active memory. The
maximum memory available (with 16 GB DIMMs) is 64 GB in a single CPU
system and 128 GB in a dual CPU system. All three channels must have
identical population with regards to size and organization. DIMMs within a
channel do not have to be identical. The population ordering for spare channel
mode is shown in the table below.
Note: Spare channel mode is only supported if the blade server has an Intel
Xeon 5600 series microprocessor. Use the Setup utility to view the system
summary and verify the type of microprocessor installed in your blade server
(see "Using the Setup utility" on page 21).
The following table shows the order that memory DIMMs are installed to use
spare channel mode.
