Memory subsystem architecture

The memory subsystem in this server is divided into channels. Each processor supports four channels, and each channel supports one DIMM slot.

Channel Population order Slot number
1 A 1
2 B 2
3 C 4
4 D 3

DIMM slots are identified by number and by letter. Letters identify the population order. Slot numbers are reported by ROM messages during boot and are used for error reporting. For the DIMM slot locations, see DIMM slot locations.
