Targeted Server Memory Kit

This NEMIX RAM kit provides 64GB of DDR5 memory in a matched set of four 16GB modules. It is built for ASRock WRX90 WS EVO motherboards that require registered ECC DIMMs. System integrators and IT professionals handling mission-critical workloads will find the specification aligned with enterprise stability requirements. The registered design and error-correcting code suit multi-socket server boards rather than consumer desktops.

Build Integration Requirements

Each module uses a 288-pin DDR5 RDIMM form factor and operates at 1.10V with a CL40 latency. The registered buffer reduces electrical load on the memory controller, freeing the platform to populate all slots without signal degradation. Installation follows standard server DIMM procedures; the kit assumes the motherboard firmware supports the stated speed and rank configuration. Buyers needing unbuffered or non-ECC memory for consumer platforms cannot use this product.

Sustained Load Behaviour

Modules are stress-tested under load before shipping to verify reliability during continuous operation. The 1Rx8 organisation and Samsung, Micron or Hynix chipsets deliver consistent throughput at the rated 4800MT/s data rate. Error-correcting code detects and corrects single-bit errors in real time, preserving data integrity during long compute runs. Systems without registered ECC support will not benefit from these protection mechanisms.

Perguntas sobre este artigo

Does the CL40 latency become the bottleneck during sustained server workloads?

CL40 is the rated CAS latency for this DDR5-4800 kit; under continuous load the latency figure itself does not change, so the limit you hit first will be the 4800 MT/s transfer rate rather than the timing.

How much heat and power does the 1.10 V registered kit produce when running all day?

Each 16 GB module operates at 1.10 V without a heat spreader; registered DDR5 at this voltage typically draws only a few watts per DIMM and runs cool enough for standard server airflow.

What motherboard features must already be present for this 288-pin RDIMM kit to work?

The board needs DDR5 RDIMM slots, registered ECC support, and validation for 4800 MT/s operation — the ASRock WRX90 WS EVO is the platform this kit is built for.
