Removing and Replacing Memory
Your system has 12 memory slots for installing DDR SDRAM memory modules. These
memory modules can either be 256MB, 512MB or 1GB, and they have to be arranged as
ordered pairs of equal size. For example, if you place a memory module of size 1GB in
slot 0A then you must insert a 1GB memory module in slot 0B. You can install a
maximum of 12GB of memory in your workstation and a minimum of 512MB.
The memory loading sequence is shown in Figure 2-15. Note that memory in the rx2600
must be loaded in matched quads. This means that you have to load two matched
memory card pairs per cell. For example, you would use the loading order provided in
Figure 2-15, and place DIMMs in slots 0A and 0B of memory cell 0 and in slots 1A and
1B in memory cell 1.
Figure 2-15 Memory Loading Order
The memory loading instructions for the system are:
1. DDR SDRAM must be loaded as matched pairs. To determine if the DIMMs are
matched pairs, look at the HP part number on the DIMMs. If the HP part numbers
match, then the DIMMs can be paired together for loading in the system.
2. It is acceptable to mix module sizes in the system as long as DIMMs within each pair
share the same HP part number. For example, it is acceptable to load a pair of
256MB DIMMs in slots 0A and 0B, and a pair of 1GB DIMMs in slots 1A and 1B. It is
also acceptable to continue with the previous example and load 512MB DIMMs in
slots 2A, 2B, 3A, and 3B.
