Functional Architecture
In the non-mirrored operation, the two DDR channels from the MCH operate in lock step. In
memory mirroring operation, the channels operate in lock-step under normal conditions, but
independently under failure and recovery conditions.
The DDR data bus is a source synchronous bus where the data signals are latched with the
differential strobe signals. Since the strobes are routed with their appropriate data group, the
flight times will be virtually the same between strobe and data.

Supported Memory

The Intel® Server Board SE7520AF2 supports four single-ranked registered DDR2-400 DIMMs
per channel, which provides a total of eight DIMMs. The maximum memory capacity supported
is 16 GB using eight modules of 1 Gbit DRAM technology devices.

DIMM Population Rules and Supported Configurations

The server board contains four banks of DIMMs: memory Bank 1 through memory Bank 4.
Memory Bank 1, with DIMM sockets 1B and 1A, is located closest to the edge of the board.
Moving in from the edge on the board are sockets for banks 2, 3, and 4 in order. Sockets
associated with any given bank are located next to each other.
