Installing a microprocessor kit and VRM Note To remove a microprocessor and VRM, reverse this procedure. The server comes with one microprocessor installed on the processor board. If you install an additional microprocessor kit, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications. Before you begin: Read "Safety information" on page 230. Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server basic input/output system (BIOS). The latest level of BIOS for the server is available through the World Wide Web. Refer to the "Getting Help Information" section of this Server Library for the appropriate World Wide Web addresses. Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/pc/us/compat/ on the World Wide Web. Attention To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. Netfinity 5600 - Type 8664 117
