Dell PowerEdge M620 Technical Guide - Page 16

More memory options are available than ever before with the Dell PowerEdge M620-greater capacities, higher frequencies, and more flexibility. The M620 supports up to 768GB of memory 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, and serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults that require service, increasing your memory reliability. System uptime is reinforced with RAS features like memory mirroring, sparing, and many others. In addition to supporting existing UDIMM and RDIMM technologies, the M620 supports load reduced DIMMs (LRDIMMs), which use a buffer to reduce memory loading and allow for greater density, allowing for the maximum platform memory capacity. Table 6 lists the memory technologies supported by the M620. Feature UDIMM No No 800, 1066, 1333, or 1600MT/s 1 or 2 2 or 4GB RDIMM Yes No 800, 1066, 1333, or 1600MT/s 1, 2, or 4 2, 4, 8, 16, or 32GB LRDIMM Yes Yes 1066 or 1333MT/s 4 32GB 2 3 3 x8 x4 or x8 x4 Yes Yes Yes Yes Yes Yes Yes (with advanced ECC mode) Yes Yes Yes Yes Yes *Although the M620 supports DIMM speeds of 800MT/s and 1066MT/s, you can only purchase this system with DIMM speeds of 1333MT/s and 1600MT/s on Dell.com.
