Installing/removing or replacing main memory
Technical data
Technology: DDR2 533/667 SDRAM unbuffered DIMM modules
240-Pin; 1.8 V; 64 Bit, ECC possible
Size: 256 MB to 8 GB DDR2
Granularity: 256, 512, 1024 or 2048 Mbyte for one socket
A current list of the memory modules recommended for this mainboard is available on the Internet
at: www.fujitsu-siemens.com/mainboards.
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 modules must meet the PC2-4200U or PC2-53000U
specification.
The mainboard has two memory channels (channel A and channel B) with two slots each
i
(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.

The installation/removal is described in the "Basic information on mainboard" manual.
