At least one memory module must be installed. Memory modules with different memory capacities
can be combined.
!
You may only use unbuffered 1,8 V memory modules with or without ECC.
DDR2-memory modules must meet the PC2-4200U or PC2-5300U specification. In
addition the DDR2-memory

The mainboard has two memory channels (channel A and channel B) with two slots each
(slot 1 and 3 or slot 2 and 4).
If you use more than one memory module, then make sure to distribute the memory
modules over both memory channels. By doing this you use the performance advantages
of the dual-channel mode.
The maximum system performance is given when the same memory size is used in
Channel A and Channel B.
To simplify equipping, the slots are colour coded.
