Server memory kit

This NEMIX RAM kit provides 64GB of DDR5 server memory across four 16GB registered DIMMs. Each module operates at 6400MHz with a CAS latency of 52 and runs at 1.1V. The 288-pin ECC RDIMM design targets enterprise platforms that require registered, error-correcting memory.

Suited for registered DDR5 platforms

The modules are built for servers and workstations that accept DDR5 6400MHz registered ECC RDIMMs with a 1Rx8 organisation. Systems that only support unbuffered UDIMMs, non-ECC memory, or earlier DDR generations cannot use this kit. Buyers needing consumer desktop memory should look elsewhere.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous operation in multi-socket servers. The 1.1V operating voltage helps limit heat output when all four DIMMs are fully populated under prolonged workloads. Stability is preserved across extended compute tasks without the error accumulation seen in non-ECC configurations.

Questions about this item

What motherboard slot and DDR generation do I need for these 288-pin DDR5 6400MHz ECC RDIMM modules?

You need a server motherboard with DDR5 RDIMM slots that support 288-pin registered ECC memory at 6400MHz (PC5-51200) and 1.1V operation.

Can I mix these 1Rx8 registered ECC sticks with older unbuffered non-ECC DDR5 DIMMs in the same system?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the memory controller requires identical module types across all populated channels.

How do I confirm the kit is running at the rated 6400MHz speed and CL52 latency after installation?

Check the BIOS memory information or a tool like CPU-Z; it should show DDR5-6400 (PC5-51200) with CAS latency 52 at 1.1V for each 16GB module.
