Intel S845WD1-E manual Supported Processors, Supported Memory Configurations

Processors

The S845WD1-E board supports a single Intel Pentium 4 processor with a ∝PGA478 socket. Processors are not included with the server board and must be purchased separately.

Table 2. Supported Processors

Type	Designation	System Bus		L2 Cache Size
Pentium 4 processor	1.6, 1.8, 2.0, 2.26, and 2.4 GHz	400	/ 533 MHz	512 KB
Pentium 4 processor	1.8, 1.9, and 2.0 GHz	400	MHz	256 KB
Intel Celeron processor	1.7, 1.8, and 1.9 GHz	400	MHz	128 KB

Memory

The SE845WD1-E server board contains two 184-pin DIMM sockets and supports up to two DDR SDRAM DIMMs. The minimum supported memory configuration is 64 MB and the maximum configurable memory size is a 2 GB stacked un-buffered DDR200/266 ECC DIMM. See the table below for supported memory configurations.

✏NOTE

Only low profile DIMMs can be supported in a 1U server chassis.

Notes:

1.If the number of DDR SDRAM devices is greater than nine, the DIMM will be double sided.

2.Front side population/back side population indicated for DDR SDRAM density and DDR SDRAM organization.
