Equipping rules Main memory

–If the memory modules are installed in pairs, they must be identical (2-way interleaved mode).

–Memory module capacity may be different for the various pairs: e.g. pair 2A/2B may be equipped with two 512 Mbyte memory modules, and pair 1A/1B may be equipped with two 1 Gbyte memory modules.

The following table shows the prescribed equipping order:

Mode	DIMM-1A	DIMM-2A	DIMM-1B	DIMM-2B
Single channel	equipped	empty	empty	empty
Single/dual	equipped	equipped	equipped	empty
channel1
	equipped	empty	equipped	empty
Dual channel	equipped	equipped	equipped	equipped

1Dual channel mode is not activated unless the size of the memory module in DIMM 2-A is equal to the sum of the memory modules in DIMM-1A and DIMM-1B (e.g.: DIMM-1A= 512Mbyte, DIMM-1B=512Mbyte, DIMM-2A=1Gbyte)
