Increasing Microprocessor Speed

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

5.Restore power to the system.

5.3Increasing Microprocessor Speed

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

•Replace the 21164 microprocessor with an AlphaPC chip that has a higher speed rating.

•Reconfigure the CPU speed selection jumpers (J28 Option 1~4).

5.3.1Preparatory 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.

A 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
