www.gateway.com Filling empty drive bays Empty drive bays in the server must be filled by drive trays with either hard drives or dummy hard drives installed. With the bezel removed, install the appropriate carrier, then replace the bezel by snapping it into place on the front of the server. Empty drive carriers for unused drive bays are included with your server. Installing memory Caution Use only DDR2-667 MHz compliant, 184-pin, SDRAM registered ECC, DIMM memory modules. The system board supports 16 DDR2 667 MHz vertical DIMMs to provide up to 64 GB of memory with ECC support. The 667 MHz differential memory clocks are driven by the AMD processor with length matching and impedance controlled through all the DIMM slots. Supported DIMM sizes include 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB. The BIOS configures the memory controller to run in single channel, dual channel, or four channel mode. Caution When using dual rank (double row) DIMMs, a maximum of four loads per memory channel is supported. This means a maximum of four dual rank DIMMs can be populated on this system board. DIMM banks must be populated using the following guidelines: There are four groups of DIMMs with four DIMMs in each group on the system board, to support processor 0, processor 1, processor 2, and processor 3. Each group supports one processor (circled). When you insert the DIMM(s), you must always start with DIMMA1 and DIMMB1 as a pair. Caution All DIMMs installed must be the same speed. Do not install more than four dual rank DIMMs or the BIOS will generate a memory configuration error. 31
