Installing Microprocessors

Installing Microprocessors

When you install an additional microprocessor, your Netfinity 5000 server operate as a symmetric multiprocessing (SMP) server. With SMP, certain ope systems and application programs can distribute the processing load bet microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Installing Microprocessor Upgrades

Your server comes with an Intel Pentium II microprocessor. This micropro incorporates MMX technology with built-in ECC level two (L2) cache. For the information about microprocessor upgrades available for your server, con IBM reseller, IBM marketing representative, or see http://www.pc.ibm.com/us/compat/ on the World Wide Web. If you do upgr microprocessor, use the instructions that come with the upgrade along w instructions in “Installing or Replacing a Microprocessor” on page 67.

Attention:

ŸIf you install an additional microprocessor that is different from installed microprocessor, your server operation might be unreliable. To

this,

use a

microprocessor

with

the

same internal and external clock

and the same cache size and voltage

requirements as those of the

installed microprocessor. Microprocessor internal and external clock

frequencies and

cache

size

must

be

identical.

Ÿ The

voltage-regulator

module

(VRM)

for

the

additional

microprocessor

pl

into

a connector on the system board

(see

“System

Board

Connectors”

page 169 for the location of the VRM connector). Because each

microprocessor

has

specific

power

and

voltage requirements,

be

sure

the

VRM

that

comes

with the

microprocessor.

Note:

The

voltage

regulator

function

for the

microprocessor

that

is

s

with

your

server

is

built

into

the

system board.

ŸIf you select a setting for the frequency switch that is greate frequency of the microprocessor, you might damage the microprocesso

frequency switch settings are shown in Table 3 on page 70.
