64GB DDR5 RDIMM for servers
This Micron registered DIMM delivers 64 GB of DDR5 memory at 6400 MHz with a CAS latency of CL52. It is built for enterprise servers and workstations that require registered memory with error-correction capability. The module suits administrators expanding capacity in compatible multi-socket platforms.
Registered design and 2Rx8 organisation
The RDIMM form factor places a register between the DRAM and the memory controller, reducing electrical load on the server bus. A 2Rx8 layout based on 16 Gbit die enables the 32 GB per rank density shown in the manufacturer highlights. These traits allow higher total system memory than unbuffered alternatives.
Standard RDIMM installation
The module installs like any DDR5 RDIMM: align the key notch, press firmly until the retention clips engage, and ensure the server BIOS recognises the new capacity. Problems usually arise when mixing registered and unbuffered DIMMs or when the platform firmware lacks support for the 6400 MHz speed grade.

Questions about this item
Will the registered buffer on this RDIMM need replacement after extended use?
The registered buffer is a permanent part of the module and has no user-replaceable components or scheduled service interval.
What limit appears first when the module runs at 6400 MHz continuously?
Thermal limits of the 16Gbit DRAM and the registering clock driver typically constrain sustained full-speed operation before any electrical margin is reached.
How much heat does a single 32 GB module produce under all-day load?
Power draw at 6400 MHz CL52 is within standard DDR5 RDIMM limits, so typical airflow in a server chassis is sufficient to keep temperatures in spec.
