Memory subsystem architecture

The memory subsystem in this server is divided into channels. Each processor supports four channels, and each channel supports three DIMM slots, as shown in the following table.

Channel	Population order	Slot number
1	A E I	12 11 10
2	B F J	9 8 7
3	C G K	1 2 3
4	D H L	4 5 6

For the location of the slot numbers, see "DIMM slot locations."

This multi-channel architecture provides enhanced performance in Advanced ECC mode. This architecture also enables Lockstep and Online Spare Memory modes.

DIMM slots in this server are identified by number and by letter. Letters identify the population order. Slot numbers indicate the DIMM slot ID for spare replacement.
