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
