Product Architecture Overview Intel® Server Board S2600GZ/GL TPS

 Each memory slot on the server board is identified by channel and slot number within that channel. 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 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.

 The BLUE memory slots on the server board identify the first memory slot for a given memory channel.

DIMM population rules require that DIMMs within a channel be populated starting with the BLUE DIMM slot or

DIMM farthest from the processor in a “fill-farthest” approach. In addition, when populating a Quad-rank DIMM

with a Single- or Dual-rank DIMM in the same channel, the Quad-rank DIMM must be populated farthest from

the processor. Note that Quad-rank DIMMs and UDIMMs are not allowed in three slots populated

configurations. Intel MRC will check for correct DIMM placement.

On the Intel

Server Board S2600GZ, a total of 24 DIMM slots is provided (2 CPUs – 4 Channels/CPU, 3

DIMMs/Channel). The nomenclature for memory slots is detailed in the following table:
