NOTE: If you decide to upgrade your system by installing a second processor, you must order the processor upgrade kits from Dell. Not all versions of
the Intel Xeon processor work properly as additional processors. The upgrade kit from Dell contains the correct version of the processor, heat sink, and
fan as well as the instructions for performing the upgrade. Both processors must have the same internal operating frequency and cache size.
NOTE: Two-way interleaving is not supported in the 256-MB single memory module configuration.
NOTE: The chip fail feature is only supported using x4 memory modules.
