Installing/removing or replacing main memory
Technical data
Technology:
DDR2 400 / DDR2 533 / DDR2 667 unbuffered DIMM modules
240-Pin; 1.8 V; 64 Bit, no ECC
Size:
256 MB to 4 GB 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/mainboards.
At least one memory module must be installed. Memory modules with different memory capacities
can be combined.
You may use only unbuffered 1.8 V memory modules without ECC.
!
DDR2-memory modules must meet the PC2-3200U, PC2-4200U or PC2-5300U
specification.
If you use more than one memory module, then make sure to distribute the memory
i
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).
