NEMIX RAM 8GB DDR4 3200 ECC UDIMM

This 8GB DDR4 ECC UDIMM operates at 3200MHz with CL22 latency and 1.2V power draw. It uses a single-rank 1Rx8 configuration built with major OEM chips from Samsung, Micron or Hynix. The module targets QNAP NAS devices and compatible server or workstation boards that accept unbuffered ECC memory.

288-pin DDR4 slot fits standard unbuffered ECC

Installation requires a motherboard with a 288-pin DDR4 slot that supports unbuffered ECC UDIMMs at 1.2V. No heat spreader is present, so airflow from case fans or CPU coolers passes directly over the chips. The single module leaves remaining slots free for future capacity expansion.

Sustained load stability from factory stress testing

Each module undergoes rigorous stress testing under load before shipment to verify reliability in continuous operation. ECC functionality detects and corrects single-bit errors during extended workloads. The 1.2V rating keeps power draw consistent across long sessions without thermal throttling concerns.

Questions about this item

What is the CAS latency that limits timing tightness under sustained load?

The module runs at CL22, so the CAS latency is 22 cycles at 3200 MT/s.

How much power does the stick draw and does it need active cooling when running continuously?

It operates at 1.2 V without a heat spreader, so power draw stays low and passive airflow is sufficient for all-day operation.

Which motherboard slot and memory type must the system already provide for this UDIMM to work?

The board needs a 288-pin DDR4 slot that accepts unbuffered ECC UDIMMs.
