Server memory kit

This NEMIX RAM kit supplies 576GB of DDR5 server memory across twelve 48GB registered DIMMs. It is built for enterprise platforms that require error-correcting code and registered buffering. The modules operate at the standard 1.1V for DDR5. This product is not for desktop or laptop computers.

Capacity and headroom

The twelve-module configuration delivers 576GB total capacity with each DIMM organised as 2Rx8. CAS latency is rated at 52 cycles at the rated speed. This density suits virtualisation hosts and large in-memory databases. Systems with fewer than twelve slots or lower per-slot limits cannot use the full kit.

DDR5 6400 interface

The modules run at DDR5 6400, also designated PC5-51200, using 288-pin registered connectors. Bandwidth and timing are fixed by this JEDEC standard. Platforms limited to lower DDR5 data rates or unbuffered DIMMs will not support these modules at their rated specification.

Questions about this item

Will the 12 modules of 48GB DDR5 6400 ECC RDIMM work alongside slower DDR5 modules I keep in the server?

Mixing speeds forces all DDR5 slots to run at the slowest installed module rate; for full 6400 MT/s performance replace every DIMM with this 12 x 48 GB kit.

How can I confirm the kit is running at 6400 MT/s with CL52 after installation?

Enter the server BIOS or run a hardware utility such as CPU-Z; the memory tab should show DDR5-6400, CAS 52, 1.1 V and 2Rx8 organisation for all 12 slots.

Does the package include only the 12 RDIMMs or are heatsinks, cables or a USB key also supplied?

The box contains exactly 12 registered ECC RDIMMs (288-pin, 2Rx8, 1.1 V); no heatsinks, cables, software media or other accessories are included.
