The Intel® Server Platform SR4850HW4 and SR6850HW4 are designed to support the 64-bit Intel® Xeon® processor MP using 90 nanometer technology.

Previous generations of the Intel Xeon processor MP are not supported for use in the Intel Server Platform SR4850HW4 and SR6850HW4.

When two or more processors are installed, all must be of identical revision, core voltage, cache size and bus/core speed. When only one processor is installed, it should be populated into the socket labeled "CPU_1" with the other CPU sockets remaining unpopulated.

For your convenience, there is a hyperlink for each of the processors featured. These hyperlinks will route you to the Intel® Processor Spec Finder tool, providing you with processor specifications and order code information.

For optimum system performance, only identical processors should be installed in a system. Processor steppings can be mixed in a system provided that there is no more than one stepping difference between the processors installed. If the installed processors are more than one stepping apart, an error (8180 through 8183) is logged in the System Event Log (SEL). Acceptable mixed stepping configurations are not reported as errors.
