Processor
The S875WP1-E server board supports a single Intel
The processor connects to the server board through the mPGA478 socket. The Intel
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:
1. DDR400: To run DDR400 memory at full speed requires an Intel
800 MHz front side bus (FSB) frequency.
2. DDR333: To run DDR333 memory at full speed requires an Intel
533 MHz FSB frequency. DDR333 memory will run at 320 MHz frequency when using an
Intel
Pentium
®
3. DDR266: DDR266 memory may only be used with an Intel
400 MHz or 533 MHz FSB frequency only.
Support for:
1. Single-channel memory.
2. Unbuffered, single or double-sided DIMMs.
3. Serial Presence Detect (SPD) memory only.
4. Support for Suspend to RAM (STR), S3 ACPI state.
5. ECC and non-ECC RAM.
6. 2.5V memory.
Support for 128 MB, 256 MB, and 512 MB memory technologies for the following memory configu-
rations:
1. Up to 1.0 GB utilizing 128 MB technology.
2. Up to 2.0 GB utilizing 256 MB technology.
3. Up to 4.0 GB utilizing 512 MB technology.
Only DIMMs tested and qualified by Intel
on the board. Note that all DIMMs are supported by design, but only fully qualified DIMMs will be
supported. Mixed mode DDR DS-DIMMs (x8 and x16 on the same DIMM) is not supported.
