Systems with 1.35 V DDR3L memory modules operate at 1.5 V if any of the following conditions exist: • Intel Xeon processor 7500 series. • A combination of standard and low voltage memory modules on system board or memory risers. • Memory riser (PowerEdge R910) not marked with the Roman Numeral "II" or system board (PowerEdge R810/M910) with Intel 7500 scalable memory buffer. DDR3L memory is backward compatible with Intel Xeon processor 7500 series and operates at standard voltage (1.5 V). System Setup Updates Memory Settings Screen Option System Memory Voltage Memory Operating Voltage (Auto default) Redundant Memory (Disabled default) Description Displays the current operating voltage of the system memory. Sets the system memory voltage selection. When set to Auto, the system automatically sets the system voltage to the optimal setting based upon the DIMM capability and the installed DIMM population. This also enables setting the system memory voltage to a higher value (1.5 V) if the DIMMs support multiple voltages and have been auto set to a lower voltage of 1.35 V. Sets the type of memory operation if a valid memory configuration is installed. When set to Mirror mode, memory mirroring is enabled, while the Spare mode allows memory sparing. The DDDC mode option enables double device data correction. NOTE: A valid DDDC configuration requires all installed DIMMs with x4 DRAMs. Information Update 7
