Functional Architecture

This chapter provides a high-level description of the functionality distributed between the
architectural blocks of the Intel Server Board S875WP1-E.
3.1

Processor and Memory Subsystem

The Intel 82875P Memory Controller Hub (MCH) is one component of the Intel 875P chipset.
The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
accelerated hub architecture interface.
3.1.1

Processor Support

The Intel Server Board S875WP1-E supports a single Pentium 4 processor (in a µPGA478
socket) with a system bus of 400 /533 /800 MHz. The server board supports the processors
listed in Table 1.
Type
Pentium® 4 processor with
Hyperthreading (HT) Technology
Pentium 4 processor with

Pentium 4 processor
CAUTION
Use only the processors listed above. Use of unsupported processors can damage the board,
the processor, and the power supply. See the Intel® Server Board S875WP1-E Specification
Update or go to http://support.intel.com/support/motherboards/server/S875WP1-E/
current list of supported processors for this board.
NOTE
Use only ATX12V or EPS12V compliant power supplies with the server board S875WP1-E.
ATX12V and EPS12V power supplies have an additional power lead that provides required
supplemental power for the Intel Pentium 4 processor. The board will not boot if you do not
connect the 20-pin (or 24-pin) and 4-pin (or 8-pin) leads of ATX12V or EPS12V power supplies
to the corresponding connectors.
Do not use a standard ATX power supply. The board will not boot with a standard ATX power
supply.
