More memory options are available than ever before with the Dell™ PowerEdge™ R620—greatercapacities, higher frequencies, and more flexibility. The R620 supports up to 768GB of memory(24 DIMMs) and speeds up to 1600 MT/s, providing high performance in a variety of applications.High memory density means there is no compromise when it comes to virtualization.Increase your uptime and reduce data loss, due to Dell’s focus on reliability, availability, andserviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults which requireservice, increasing your memory reliability. System uptime is reinforced with RAS features likememory mirroring, sparing, and many others.In addition to supporting existing unbuffered DIMMs (UDIMM) and registered DIMMs (RDIMM), theR620 supports load reduced DIMMs (LRDIMM), which use a buffer to reduce memory loading andprovide greater density, allowing for the maximum platform memory capacity.Table 8 lists the memory technologies supported by the R620.Feature UDIMM RDIMM LRDIMMRegister No Yes YesBuffer No No YesFrequencies 800, 1066, 1333, or1600MT/s800, 1066, 1333, or1600MT/s 1066 or 1333MT/sRanks supported 1 or 2 1, 2, or 4 4Capacity per DIMM 2 or 4GB 2, 4, 8, 16, or 32GB 32GBMaximum DIMMS per channel 2 3 3DRAM technology x8 x4 or x8 x4Temperature sensor Yes Yes YesECC Yes Yes YesSDDC Yes (with advancedECC mode) Yes YesAddress parity Yes Yes Yes
