19 PowerEdge R520 Technical GuideMemory speedThe R520 supports memory speeds of up to 1600MT/s,depending on DIMM types installed andconfiguration. The loading within a channel significantly affects memory speed.Table 9 illustrates the maximum achievable speed of the Intel Xeon processor E5-2400 productfamily based on memory loads. Green boxes are defaults for performance per watt White boxes (with lower voltage) can save power but will run at slower speeds White boxes (with higher voltage) can be custom configured in the biosTable 9.
