Installing memory Your server supports from 256 MB to 12 GB* of total DDR333 or DDR266 memory. Supported DIMM sizes include 256 MB, 512 MB, 1 GB, and 2 GB. Caution Modules must be installed in banks in identical pairs. Use only DDR266 or DDR333 compliant, 184-pin, SDRAM registered x72 ECC, LP (low profile) DIMM memory modules. Install memory first into Bank 1, then Bank 2, then Bank 3. If memory is installed incorrectly, your server will not start. The BIOS configures the memory controller to run in either single channel or dual channel mode, depending on the following: ■ If one or more fully populated DIMM banks are detected, the memory controller will run in dual channel mode. DIMM banks must be populated using the following guidelines: ■ DIMM banks must be populated in order, starting with Bank 1. ■ Single rank DIMMs must be populated before dual rank DIMMs. ■ When using DDR333 DIMMs, a maximum of four DIMMs can be populated when all four DIMMs are dual rank (double row) DIMMs. ■ DDR266 and DDR333 memory can be mixed on the server board, but when mixing DIMM types, DDR333 memory will be treated as DDR266 * When using Dual Rank (double row) DIMMs, a maximum of four loads per memory channel is supported, therefore a maximum of four dual rank DIMMs can be populated on this system board. www.gateway.com 65
