Supported Processors
This section describes the processors supported by the DX400-SN motherboard and how to install them.
The DX400-SN Motherboard only supports Intel Pentium Xeon processors with a Front
Side bus speed of 400 MHz . If two processors are installed, both processors must run the
same core frequency speed. Installing processors of different core frequencies speed may
damage the motherboard and processors.
The processor is packaged in a Organic Land Grid Array (OLGA). The Pentium Xeon Processors implement
integrated L2caches. The Pentium Xeon processor increases Performance for server and workstation
applications by adding either 512KB or 1MB of integrated L3 cache, which is also 8-way set associative.
The System Bus uses Source-Synchronous Transfer (SST) of address and data to improve performance and
enables data transfers at a frequency of 400MHz.This allows the processors to have 3.2GB/sec data transfer
rate .The control signals and bus phases are based on 100MHz system clock. This enhanced bus protocol
and internal architecture increases performance beyond previous levels.
The Processor Information ROM is a 128 byte read –only device that incorporates Intel processor specific
data .The OEM EEPROM, also known as the Scratchpad EEPROM, is a 128-byte read/write EEPROM in
which an OEM may program system specific data. The Thermal Sensor monitors the temperature of the
processor die.
Installing the Processors and Retention Mechanism
Single processor:
Install the processor in the socket marked ‘CPU0’
For Dualprocessors
the following values must be identical for both processors:
·Host bus speed
·Processor core frequency
·Cache size
·Cache type (either discrete or advanced transfer)
·Operating voltages
Installing the retention on the motherboard.

Processor installation.
a. Be sure the first pin position in the right direction and install the processor(C), see figure down below.
b. There is a handle at the side of socket603 (F), and it should be fully pulled up or the processor(C) can not
be installed on it. After that, pull down the handle of socket603 (F).
c. If only one processor will be installed on motherboard, it should be installed in the socket P0 and leave the
socket P1 with nothing.
Screws:
a. Support the motherboard (G) on the chassis (I) after nuts (J) and screws (H) have screwed on the chassis
(I) first, see the figure down below.
b. Screw the retainer (E) on the chassis (I) thru motherboard (G), so that the retainer (E) will be fixed on the
motherboard (G).

Socket P0

Heatsink installation.
a. Before installing a heatsink (B), it should be sure that the processor(C) had be installed.
b. Put some thermo grease or stick a thermo pad at the bottom of heatsink (B).
c. Put the heatsink (B) on the processor(C) and make sure they
contact with each other well by thermo grease or thermo pad,
see figure in the right.
d. Put the clips (A) on the side-edge of heat, which the side with fillister, and make sure the key of clip (A) slid
into the fillister.
e. Push the both ends of clip (A) once at a time with the fastener retainer (E).
There are three major steps about the Pentium Xeon processor installation for a DX400-SN
motherboard.
1. Motherboard and retainers installation.
2. Processors installation.
3. Heatsinks installation.
1. Motherboard and retainers installation.
To install the motherboard on the chassis, it should be clarify the method of fixing fastener retainers (E) first.
