For moreinformation, see “Using the Setup utility” on page 126. For more information andnotes about installing DIMMs, see “Installing a memory module” on page 47 and“Independent memory mode” on page 55..Consider the following information when using the memory mirroring feature inindependent memory mode:v Independent memory mode provides the most efficient performance.v You can populate DIMMs in any order and there are no matching requirements.However, the DIMM population sequence in the following table will provide thebest performance when operating in the supported memory modes.v When you operate in this mode, the memory channel operates at twice theDDR3 data rate.56 System x3850 X6 and x3950 X6 Types 3837 and 3839: Installation and Service Guide
