The low voltage memories with 1.35V are clocked with 1.5V when mixed with 1.5V memories via the fallback option available in the memory. Memory configuration for good system performanceDistribute the memories evenly among the memory slots and evenly among the CPUsIf there is more than one CPU, the memories per CPU should be configured identically (mirrored to the other CPU).
