DIMM and memory configurations must adhere to the following:

2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts

Unbuffered single-sided or double-sided DIMMs.

Maximum total system memory: 2 GB; Minimum total system memory: 64 MB

200/266 MHz DDR SDRAM DIMMs only

Serial Presence Detect (SPD)

Suspend to RAM

Non-ECC and ECC DIMMs

Only DIMMs tested and qualified by Intel or a designated memory test vendor will be supported on the S845WD1-E server board. A list of qualified DIMMs will be made available. Note that all DIMMs are supported by design, but only fully qualified DIMMs will be supported.

Intel 845E Chipset

The Intel 845E chipset consists of the following devices:

Intel 82845E Memory Controller Hub (MCH) with Accelerated Hub Architecture (AHA) bus

Intel 82801BA I/O Controller Hub (ICH2) with AHA bus

Intel 82802AB Firmware Hub (FWH)

The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the Accelerated Hub Architecture interface. The ICH2 is a centralized controller for the board’s I/O paths. The FWH provides the nonvolatile storage of the BIOS.

Intel 82845E Memory Controller Hub (MCH)

The MCH supports the data integrity features supported by the Pentium Pro bus, including address, request, and response parity. The 845E chipset always generates ECC data while it is driving the processor data bus, although the data bus ECC can be disabled or enabled by BIOS. It is enabled by default.

The MCH provides the following:

An integrated Synchronous DRAM memory controller with auto detection of SDRAM.

Support for ACPI Rev 1.0b compliant power management.
