Memory and Microprocessor Configuration 5–3

Increasing Microprocessor Speed

5.3 Increasing Microprocessor Speed

This section describes how to complete the following actions to increase

microprocessor speed:

• Replace the Alpha 21164 microprocessor with an Alpha chip that has a higher

speed rating.

• Reconfigure the clock divisor jumpers.

5.3.1 Preparatory Information

Caution: Static-Sensitive Component – Due to the sensitive nature of electronic

components to static electricity, anyone handling the microprocessor

must wear a properly grounded antistatic wriststrap. Use of antistatic

mats, ESD approved workstations, or exercising other good ESD prac-

tices is recommended.

An Alpha 21164 microprocessor with a higher speed rating is available from your

local distributor. See Appendix A for information about supporting products.

When replacing the microprocessor chip, also replace the thermal conducting

GRAFOIL pad. See Appendix A for information about the parts kit, which includes

the heat sink, GRAFOIL pad, two hex nuts, heat-sink clips, 60-mm fan, fan guard,

and four screws.

5.3.2 Required Tools

The following tools are required when replacing the microprocessor chip:

A TS30 manual nut/torque driver (or equivalent) with the following attachments is

required to affix the heat sink and fan to the microprocessor’s IPGA package:

• 1/4-inch hex bit

• 7/16-inch socket with 1/4-inch hex drive

• #2 Phillips-head screwdriver bit
