Processors
The S845WD1-E board supports a single Intel Pentium 4 processor with a µPGA478 socket.
Processors are not included with the server board and must be purchased separately.

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.
