Compute Module MFS2600KI TPS Functional Architecture
Revision 1.0 13
Intel order number: G51989-002
The silk screened DIMM slot identifiers on the board provide information about the
channel, and therefore the processor to which they belong. For example, DIMM_A1 is
the first slot on Channel A on processor 1; DIMM_E1 is the first DIMM socket on
Channel E on processor 2.
The memory slots associated with a given processor are unavailable if the
corresponding processor socket is not populated.
A processor may be installed without populating the associated memory slots provided
and a second processor is installed with associated memory. In this case, the memory is
shared by the processors. However, the platform suffers performance degradation and
latency due to the remote memory.
Processor sockets are self-contained and autonomous. However, all memory subsystem
support (such as Memory RAS, Error Management,) in the BIOS setup are applied
commonly across processor sockets.
For a complete list of supported memory for the Intel

Compute Module MFS2600KI, refer to the
Tested Memory List published in the Intel
®
Server Configurator Tool.
