Upgrading main memory
Technical data
Technology: DDR 266, DDR 333 or DDR 400 unbuffered DIMM modules
184-Pin; 2.5 V; 64 Bit, no ECC
Size: 64, 128 Mbytes up to 2 Gbyte DDR-SDRAM
Granularity: 64, 128, 256, 512 or 1024 Mbyte for one module
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 2,5 V memory modules. Buffered memory modules are not
supported.
DDR-DIMM memory modules must meet the PC2100, PC2700 or PC3200 specification.
The mainboard has two memory channels. The maximum system performance is only
available when memory modules (same order number, same manufacturer, same size,
memory density) are used in both memory channels.
Memory clock pulse speed
The memory clock pulse speed is affected by the processor chipset and system bus. The table
shows the memory speed in dependence on the system bus.
System bus (MHz) DDR333 (MHz) DDR266 (MHz)
533 333 266
400 333 266
