NEMIX RAM 32GB DDR4 3200 CL22 2Rx4 ECC RDIMM memory upgrade

SKU CH-637M-42P3K

32 GB DDR4 3200 ECC registered RDIMM with CL22 latency for Gigabyte WRX80 server motherboards

  • Total capacity32 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 32 GB capacity expands server memory headroom
  • DDR4 3200 speed delivers high data throughput
  • ECC registered design protects data integrity
  • 2 V operation reduces power draw
  • 288-pin RDIMM form factor fits compatible Gigabyte boards

Capacity and role

This 32 GB DDR4 ECC RDIMM is built for servers and workstations that require registered memory with error correction. It targets system administrators and integrators upgrading Gigabyte WRX80 platforms where stability outweighs raw speed.

Sustained-load behaviour

Rated at DDR4-3200 with CL22 timings and 1.2 V operation, the module maintains consistent throughput during prolonged compute tasks. The 2Rx4 organisation and registered buffer help the memory controller manage heavy multi-threaded workloads without signal degradation.

Build and connectors

The 288-pin RDIMM form factor fits standard DDR4 server slots and relies on major OEM DRAM from Samsung, Micron or Hynix. No heat spreader is included, so airflow in the chassis must handle thermal dissipation. Buyers needing unbuffered UDIMMs or non-ECC modules for consumer boards cannot use this part.

Questions about this item

Does the 1.2 V DDR4 3200 module run hot or noisy in a 24/7 server?

The RDIMM operates at standard 1.2 V with no heat spreader, so thermals depend on chassis airflow; it has no moving parts and produces no audible noise.

What motherboard slot and firmware support are required for this ECC RDIMM?

A 288-pin DDR4 RDIMM slot and a platform that enables ECC registered memory — the Gigabyte WRX80-SU8-IPMI is a validated example.

Can I mix this 32 GB 2Rx4 stick with older 1Rx8 DDR4 modules?

Mixing ranks and organisations is not recommended; the board will likely down-clock to the slowest module and may disable ECC or multi-rank features.
