Installing memory-module kits Note To remove a memory-module kit, reverse this procedure. Adding memory to the server is an easy way to make programs run faster. You can increase the amount of memory in the server by installing options called memory-module kits. Each kit contains one industry-standard, dual-inline memory module (DIMM). The server uses a noninterleaved memory configuration. The server comes with a DIMM installed on the processor board in connector J1. Notes 1. Install additional DIMMs in connectors J2, J3, and J4, in that order. (See the following illustration for memory connector locations.) If you mix DIMM sizes, install the largest sized DIMM in connector J1, the next largest sized DIMM in connector J2, and so forth. 2. The Netfinity 5600 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. The server supports a minimum of 128 MB and a maximum of 4 GB of system memory. Only 133 MHz, 3.3 V, 168-pin, 8-byte, 72-bit registered, synchronous-dynamic-random-access memory (SDRAM), error correcting code (ECC) with x4 configuration DIMM memory complying with PC 133 Registered DIMM Specification, Revision 1.0 or later is supported. 3. 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 in 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 "Using the System Configuration Utility main menu" on page 27 for more information. Netfinity 5600 - Type 8664 121
