Server Memory Kit

This NEMIX RAM kit provides 288GB of DDR5 capacity across twelve 24GB RDIMM modules. It is built for enterprise servers that require registered ECC memory running at 6400MHz. Workstations and consumer PCs that accept only unbuffered DIMMs cannot use this kit.

Installation Notes

Each module fits a standard 288-pin DDR5 slot and operates at the rated 1.1V without manual voltage adjustment. The registered buffer adds a clock cycle, so the memory controller must support RDIMMs; systems expecting UDIMMs will not post. Verify that the server board qualifies 2Rx8 organisation and the PC5-51200 speed grade before fitting all twelve modules.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors on the fly, preventing data corruption during continuous workloads. The registered design reduces electrical load on the memory bus, helping signal integrity when all twelve slots are populated. CAS latency of 52 is consistent across the kit, delivering predictable throughput for long-running database or virtualisation tasks.

Questions about this item

How can I confirm the kit is running at 6400MHz with CAS latency 52 after installation?

Check the BIOS or UEFI memory information screen; it should report DDR5 6400 (PC5-51200) speed and CL52 timings at 1.1V for each of the 12 modules.

What is included in the package and do I need any extra parts to install it?

The box contains 12 registered ECC RDIMM modules, each 24GB, 288-pin, 2Rx8 organisation; no additional components are required for a compatible server motherboard.

Which capacity version should I choose if my server supports up to 288GB total?

This single kit provides the full 288GB limit using twelve 24GB sticks, so no mixing of different capacities is needed.
