64 GB ECC UDIMM kit for NAS servers

This NEMIX RAM kit provides 64 GB of DDR4 ECC unbuffered memory in a matched set of four 16 GB modules. It runs at 2666 MHz with CL19 latency at 1.2 V. The modules use 288-pin UDIMM form factor and are built with major OEM DRAM chips.

Suited for ASUS Lockerstor NAS upgrades.

The kit is designed for compatibility with ASUS Lockerstor AS-16GECD4-U NAS units and similar systems that accept unbuffered ECC UDIMMs. Builders whose motherboards require registered or load-reduced DIMMs cannot use this memory. Systems needing higher densities per slot or non-ECC modules should consider other configurations.

2666 MHz DDR4 speed rating

The decisive specification is the DDR4 2666 (PC4-21300) speed grade. A motherboard or NAS that only supports lower DDR4 frequencies will still run the modules, but at the slower supported rate. Verify that your platform accepts unbuffered ECC UDIMMs at this speed before purchase.

商品問答

What motherboard slot does this 288-pin DDR4 kit require?

A standard 288-pin DDR4 DIMM slot running at 1.20 V is required for each of the four 16 GB modules.

Will this CL19 DDR4-2666 kit run with slower DDR4 modules I already own?

The kit operates at 2666 MT/s CL19; the motherboard will clock all installed DDR4 down to the slowest module’s speed and loosest timings.

How can I confirm the ECC function is active after installing the 4x16 GB kit?

Check the BIOS memory information page — it should show 64 GB total with ECC enabled, and the OS should report correctable error counters.
