Processor Each server board must have one processor installed. Each board can use a different processor. For a list of supported processors, see http://support.intel/com/support/ motherboards/server/X38ML. Memory Each server supports four DDR2 667 / 800 MHz unbuffered ECC DIMMs. The maximum memory capacity is 2 GB unbuffered, 1 Gbit DDR2 memory. The minimum is one 256MB DIMM. The four slots are partitioned into Channel A and Channel B. Channel A consists of DIMM A1 and DIMM A2. Channel B consists of DIMM B1 and DIMM B2. DIMM A1 is the closest to the MCH. DIMMs must meet the following requirements: • If dual-channel operation is desired, Channel A and Channel B must be populated identically (i.e., same capacity). • Use DDR2 667 / 800 only. • The speed used on all the channels is the slowest DIMM in the system. • Use ECC or non-ECC DIMMs. • You can mix different memory technologies (size and density). • For single-channel mode, either channel may be used and DIMM sockets within the same channel can be populated in any order. • For dual-channel interleaved mode, DIMM sockets may be populated in any order as long as the total memory in each channel is the same. • For dual-channel asymmetric mode, DIMM sockets may be populated in any order. For a complete list of supported memory DIMMs, see http://support.intel/com/support/ motherboards/server/X38ML. 12 Intel® Server System SR1520ML User's Guide
