Server-grade DDR5 module

This single 32 GB DDR5 6400 MHz registered DIMM delivers error-correcting code protection for mission-critical workloads. It operates at 1.1 V with a CAS latency of 52 and uses a 2Rx8 organisation suited to high-density server platforms. The 288-pin form factor fits DDR5 RDIMM slots in compatible enterprise chassis.

Registered ECC architecture

On-board register buffers address and command signals to reduce electrical load on the memory controller. ECC circuitry detects and corrects single-bit errors, preserving data integrity during sustained compute tasks. The registered design enables larger memory populations per channel than unbuffered alternatives.

OEM DRAM foundation

Memory chips are sourced from major manufacturers such as Samsung Micron or Hynix, ensuring consistent binning and supply stability. The module targets server platforms that require DDR5 6400 registered ECC memory and is not intended for consumer desktop or laptop systems. Builders needing unbuffered DIMMs or non-ECC configurations should select a different product class.

Questions about this item

Will the Samsung Micron or Hynix chips on this DDR5 6400 module need replacement during the server's life?

The DRAM chips from major OEM suppliers are rated for continuous server operation and are not a scheduled replacement item; the module carries a lifetime replacement warranty from NEMIX RAM.

What limit appears first when this 2Rx8 registered DIMM runs at 6400 MHz under sustained load?

The CAS latency of 52 cycles at DDR5 6400 sets the timing boundary that the memory controller must meet continuously.

How much power does the 1.1 V DDR5 RDIMM draw when the server runs all day?

Each 32 GB stick operates at 1.1 volts, so power draw scales with the 32 GB capacity and the 6400 MHz data rate during constant use.
