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.
