IBM® xSeries 350: User’s Reference
To use the 4-way memory interleaving technology in your server, you must install
DIMMs in all four connectors in each populated bank.
7. Install only 3.3 V, 168-pin, 8-byte, 100 MHz, PCI, PC100-322-622R, registered
synchronous dynamic random-access memory (SDRAM) with error correcting
code (ECC). Only 100MHz, 72-bit, registered, synchronous, x4 SDRAM
configuration DIMM memory is supported for the 128 MB, 256 MB, 512 MB, and
1GB DIMMs.
8. Installing or removing DIMMs changes the configuration information in the
server. Therefore, after installing or removing a DIMM, you must save the new
configuration information using the Configuration/Setup Utility program. When
you restart the server, the system displays a message indicating that the memory
configuration has changed. Start the Configuration/Setup Utility program and
select Save Settings. See “Chapter 3. Configuring your server,” on page 13 for
more information.
Install the DIMMs in the order shown in Table 4.
Before you begin:
• Review “Before you begin” on page 39.
• Read the documentation that comes with your option.
To install a DIMM:
Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, see “Handling
static sensitive devices” on page 40.
1. Turn off the server and disconnect all power cords and external cables; then,
remove the top cover (see “Removing the server top cover and bezel” on page 41).
