Memory - Dell PowerEdge M620 Technical Manual

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
(using 32 GB DIMMs—available Q2 2012) 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.
