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 256-
MB 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.
