Intel S875WP1-E manual Processor, Memory

Processor

The S875WP1-E server board supports a single Intel Pentium 4 processor with an mPGA478 socket. The processor connects to the server board through the mPGA478 socket. The Intel Pentium 4 processor can be removed and replaced to accommodate a supported higher speed processor.

The server board S875WP1-E supports the following processors.

Memory

The S875WP1-E server board contains four 184-pin DIMM sockets and supports up to four DDR SDRAM DIMMs. The minimum supported memory configuration is 128 MB and the maximum configurable memory size is 4 GB with stacked unbuffered DDR266/333/400 ECC DIMMs.

Supported memory configurations are as follows:

•Up to four dual-channel 184-pin Double Data Rate (DDR) SDRAM DIMMs connectors with gold-plated contacts. Supported memory configuration are:

DDR400: to run DDR400 memory at full speed requires an Intel Pentium 4 processor with 800 MHz front side bus (FSB) frequency.

DDR333: to run DDR333 memory at full speed requires an Intel Pentium 4 processor with 533 MHz FSB frequency. DDR333 memory will run at 320 MHz frequency when using an Intel Pentium 4 processor with 800 MHz FSB frequency.

DDR266: DDR266 memory may only be used with an Intel Pentium 4 processor with 400 MHz or 533 MHz FSB frequency only.

•Support for:

Single-channel memory

Unbuffered, single or double-sided DIMMs

Serial Presence Detect (SPD) memory only

Support for Suspend to RAM (STR), S3 ACPI state

ECC and non-ECC RAM

2.5 V memory
