Installing Microprocessors Working with Microprocessors Your server comes with an Intel Pentium II microprocessor. This microprocessor incorporates MMX technology with built-in ECC L2 cache. For the latest information about microprocessor upgrades available for your server, contact your IBM reseller or IBM marketing representative. If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in "Installing or Replacing Microprocessors" on page 90. When you install an additional microprocessor, your Netfinity 3500 server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between microprocessors. This can enhance performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications. The voltage regulator function is built into the system board. This feature supports each microprocessor on the system board. If you install a second microprocessor, it must operate at the same voltage as the primary microprocessor to ensure proper operation of the voltage regulator feature. Note: The illustrations in this section might differ slightly from your hardware. Chapter 4. Installing Options 89
