NEMIX RAM 8GB DDR4 2400 UDIMM

This module is an unbuffered, non-ECC DDR4 desktop DIMM built for systems that accept 288-pin memory at 2400 MT/s. It targets users upgrading a QNAP NAS or a standard PC motherboard that specifies PC4-19200 speed and 1.20 V operation.

Capacity and headroom

The single 8 GB rank provides enough space for typical NAS services, light virtualization and everyday desktop workloads. Memory-intensive tasks such as large database caches or heavy video editing will exhaust the capacity and require additional modules or a higher-density kit.

Build quality and connectors

Chips are sourced from major OEM suppliers including Samsung, Micron or Hynix and each stick undergoes stress testing under load before shipping. The plain green PCB lacks a heat spreader or LEDs, keeping the profile low for tight NAS chassis, while the standard 288-pin edge connector ensures straightforward insertion into any compatible UDIMM slot.

Questions about this item

Will this module fit a QNAP NAS that specifies the RAM-8GDR4A0-UD-2400 part number?

Yes, the module is listed as compatible with that QNAP part number and uses the standard 288-pin DDR4 UDIMM form factor required by those NAS units.

Does the memory require ECC support on the motherboard?

No, this is a non-ECC unbuffered DIMM, so it works in standard desktop boards and QNAP NAS models that accept non-ECC memory.

What speed and latency will the module run at by default?

It operates at DDR4 2400 with a CAS latency of CL17 at 1.20 V, matching the PC4-19200 specification.
