Removing or Installing Memory

The silkscreen on the server board for the DIMMs displays DIMM1B, DIMM1A,
DIMM2B, DIMM2A, DIMM3B, and DIMM3A starting from the edge of the server
board. DIMM3A is the socket closest to the processor socket.
Note: The DIMMs that are to be installed in the server board MUST match the DIMM slots
present on the server board. DDR DIMMs will not physically fit into a server board
designed to support DDR2 DIMMs. DDR2 DIMMs will not physically fit into a server
board designed to support DDR DIMMs.

Memory Requirements

The Intel® Server Board SE7520JR2 provides six DIMM sockets across two channels:
Channel A and Channel B. Channel A consists of DIMM sockets 1A, 2A, and 3A.
Channel B consists of DIMM sockets 1B, 2B, and 3B. Refer to the Tested Memory List at
http://www.intel.com/support/motherboards/server/ssr212cc/
supported memory.
If six DIMMs are installed, the following maximum capacity is possible:
•
DDR2-400: Maximum capacity of 16 GB.
A minimum of one 256-MB DIMM is required in DIMM socket 1A or 1B. This uses
single-channel interleave. However, for dual-channel interleave providing optimum
performance, a minimum of two DIMMs should be installed in DIMM sockets 1A and
1B. Except for the option of installing a single DIMM in sockets 1A or 1B, DIMMs must
be installed in pairs and populated as follows:
•
DIMM1A and DIMM1B: Populate these two sockets first
•
DIMM2A and DIMM2B: Populate these sockets in addition to DIMM1A and
DIMM2A if four DIMMs are to be used
•
DIMM3A and DIMM3B: Populate these sockets after DIMM1A, DIMM1B,
DIMM2A, and DIMM2B have been populated
DIMMs must meet the following requirements:
