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
