Technical Guide

Memory subsystem
The R450 supports up to 16 DIMMs, with up to 1024GB of memory and speeds of up to 3200MT/s.
The R450 supports registered (RDIMMs) 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.
Topics:
• Supported memory
• Memory speed

NOTE: Maximum memory speed depends on the processor specification. The DIMM can support upto 3200 MT/s, but the
memory may not support this memory speed. See Supported Processors table for the processor type and the supported
memory speed.
