Upgrading main memory
Technical data
Technology: DDR2 400 / DDR2 533 unbuffered DIMM modules
184-Pin; 1.8 V; 64 Bit, no ECC
Size: 256 Mbytes to 4 Gbytes DDR2
Granularity: 256, 512 or 1024 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
.
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. Buffered memory modules are not
supported.
DDR2 memory modules must meet the PC3200 or PC4300 specification.
i
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.
With a memory configuration of 4 Gbytes the visible and usable main memory can be
reduced down to 3 Gbytes (depending on the system configuration).
