Upgrading main memory

Technical data

Technology:

DDR 333 or DDR 400 unbuffered DIMM modules

 

184-Pin; 2.5 V; 64 Bit, no ECC

Size:

128 Mbytes to 4 Gbyte DDR 333 SDRAM

 

128 Mbytes to 4 Gbyte DDR 400 SDRAM

Granularity:

128, 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 only use unbuffered 2,5 V memory modules. Buffered memory modules are not supported.

DDR-DRAM memory modules must meet the PC2700 or PC3200 specification.

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).
