4.1DDR2 DIMM Support
DDR2 memory offers an effective doubling of the clock rate over DDR memory since data transfers happen on both the rising and falling edge of the clock (double pumped). Due to the lower clock frequency, and improved manufacturing technology, a significant power savings can be achieved, especially when the data bus is not active.
The Intel® Server Board Set SE8500HW4 Memory Board supports DDR2 400MHz (also referred to as
Speeds less than DDR2 400MHz may be used, but performance will be reduced. Intel has only validated DDR2 400MHz SDRAM for specific memory parts; refer to the Intel® Server Board Set SE8500HW4 Board Memory Qualification List
4.2Installation Order
When only using two memory DIMMs, the first pair of sockets, DIMM_1A and DIMM_1B, must be populated. When using a mixture of
4.3Memory Initialization
The XMB provides hardware memory initialization. The initialization engine performs two passes. On the first pass, it writes the entire segment. On the second pass, it reads and tests the entire segment. Any errors are logged with the failing DIMM being flagged for BIOS.
