NOTE: Although mixed DIMM configurations may be functional, platform validations are performed only
on systems configured with identical DIMMs.
The S2400EP4 server board memory is implemented according to the following rules
•
DIMMs are organized into physical slots on DDR3 memory channels that belong to processor
sockets.
•
The memory channels from processor socket 1 are identified as Channel A, B, C.
The memory channels from processor socket 2 are identified as Channel E, F.
•
Each memory slot on the server board is identified by channel and slot number within the channel.
For example, DIMM_A1 is the first slot on Channel A on processor 1; DIMM_D1 is the first DIMM
socket on Channel E on processor 2.
•
The memory slots associated with a given processor are unavailable if the given processor socket is
not populated.
•
A processor can be installed without populating the associated memory slots, provided the other
processor is installed with associated memory. In this case, the memory is shared by the processors.
However, the platform suffers performance degradation and latency because of the remote memory
accesses.
•
Processor sockets are self-contained and autonomous. However, all memory subsystem support (i.e.,
Memory RAS, Error Management, etc.) in the BIOS setup is applied commonly across processor
sockets.
•
The blue memory slots on the server board identify the first memory slot for each memory channel.
•
For more information about population considerations, see Section 3.2.2.2 “Memory Slot Identification
and Population Rules” in the Intel® Server Board S2400EP4 Family TPS.

3.3.3 Installing Memory DIMMs
NOTE: To reduce the risk of electrostatic discharge (ESD) damage to the processor or the DIMM, be sure
to use a ground strap attached to the front panel (with the bezel removed).
To install DIMMs in the S2400EP4 server board slots:
1.
Power down the server and remove all peripheral devices and the power cord(s)
2.
Remove the chassis cover. For instructions, see Section 3.2.1 “Removing the Chassis Cover”.
3.
Note the location of the alignment notch. ( Figure 12, “B”)
4.
Insert the DIMM, making sure the connector edge of the DIMM aligns correctly with slot. (“E”)
