Memory and Microprocessor Configuration

3.

Align the DIMM so that the notch in the DIMM matches the key in the socket. 

4.

Firmly push the DIMM straight into the connector. Ensure that the DIMM snaps 
into the plastic locking levers on both ends. 

5.

Restore power to the system. 

This section describes how to complete the following actions to increase 
microprocessor speed: 

Replace the Alpha 21164PC microprocessor with an Alpha chip that has a higher 
speed rating.

Reconfigure the clock divisor switches.

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 21164PC 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, 52-mm fan, and four 
screws. 

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

3/8-inch socket with 1/4-inch hex drive

#2 Phillips-head screwdriver bit
