Interleaving and Non-Interleaving Memory Configuration

This server supports both interleaving and non-interleaving memory configurations.
Interleaving memory increases bandwidth by allowing simultaneous access to more
than one block of data (for example, overlapping Read-Writes). This is accomplished
by dividing the system memory between pairs of DIMMs and Writing-Reading
blocks of data to/from both simultaneously. In order to take advantage of interleaving
memory, identical DIMMS must be installed in pairs. DIMMs can also be installed
singularly if memory interleaving is not desired.
Activating Interleaving Memory
Interleaving memory functionality is automatically activated whenever two identical
DIMMs are detected in sockets 1 and 2. If sockets 3 and 4 are populated, it must be
with identical DIMMs as well. If identical DIMMs are installed in sockets 1, 2 and 3,
this is considered non-interleaving. You must have an even number of DIMMs
installed to support interleaving.
The server identifies memory mode in two ways. At post, the ROM will display a
interleaving or non-interleaving message. In addition, The RBSU main menu will
identify the memory mode following the
the information block to the right of the menu options list. Refer to Chapter 5,
"Server Configuration and Utilities" for more information.
Interleaving Memory Guidelines
For interleaving memory functionality, follow the guidelines noted below:
·
Memory must be installed in identical pairs. Pairs are considered to be DIMMs
installed in sockets 1 and 2 or 3 and 4.
·
Populate DIMM sockets 1 and 2 first before installing in sockets 3 and 4
(if needed). Refer to Figure 3-25 and Table 3-3.
