5 Memory

More memory options are available than ever before with the Dell PowerEdge R730 and R730xd —
greater capacities, higher frequencies, and more flexibility. The R730 and R730xd support up to
768GB of memory (24 DIMMs) and speeds up to 2133MT/s (2 DIMMs per channel), providing high
performance in a variety of applications. High memory density means there is no compromise when
it comes to virtualization. 64GB DIMMs will be available immediately post-RTS and will expand the
memory footprint to 1.5TB.
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 which require
service, increasing your memory reliability. System uptime is reinforced with RAS features like
memory mirroring, sparing, and many others.
The R730 and R730xd support both registered and load reduced DIMMs (LRDIMMs), which use a
buffer to reduce memory loading and provide greater density, allowing for the maximum platform
memory capacity. Unbuffered DIMMs (UDIMMs) are not supported.
