Cisco UCS 16GB 1Rx8 DDR5-6400 RDIMM

Its speed grade is DDR5-6400. The Cisco UCS-MRX16G1RE5 is a 1Rx8 registered ECC DIMM for UCS servers, and its 6400 MT/s data rate is meant for platforms that can use it.

Faster memory only pays off when processors and firmware support the speed. Before ordering, confirm your UCS server can run DDR5 at 6400; otherwise the memory clocks down and the extra speed goes unused.

At 16GB per module, the capacity is modest, so this part suits builds that populate many channels for bandwidth. It is also a replacement for a failed module of the same type.

Mixing speeds in a single server usually forces all modules to the slowest rate, so keep your population uniform.

The module is available new and refurbished with 1 year or 3 years of warranty, and used with a 90 day warranty. Add UCS-MRX16G1RE5 to your list with the processor generation of your UCS server.
