Four green DDR5 server memory sticks with black heat spreaders and gold contacts

NEMIX RAM

NEMIX RAM 64GB (4 x 16GB) DDR5 6400MHz ECC RDIMM server RAM

SKU CH-F9RW-P2HXN

Four 16 GB DDR5 registered ECC modules at 6400 MHz with CL52 and 1.1 V for server memory upgrades

  • Capacity64GB (4 x 16GB)
  • SpeedDDR5 6400 (PC5 51200)
  • CAS Latency52
  • Voltage1.1V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 64GB total capacity from four 16GB modules
  • DDR5 6400 speed rated at PC5-51200 bandwidth

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.
