Capacity and compatibility

This 16GB DDR4 module targets NAS and desktop upgrades where non-ECC unbuffered memory is required. The single stick fits 288-pin UDIMM slots and matches QNAP part RAM-16GDR4-LD-2133 for direct replacement.

Speed and voltage limits

DDR4 2133 at CL15 sets the practical bandwidth ceiling at PC4-17000 while the 1.20V operating voltage keeps power draw within standard desktop limits. No heat spreader is present, so airflow across the PCB handles thermal load.

Build and daily handling

Major OEM chips from Samsung, Micron or Hynix are assembled without LEDs or a spreader, keeping the profile low for tight NAS bays. The bare green PCB means installers should hold edges only and avoid flexing the module during insertion.

Questions about this item

Will this module fit my QNAP NAS that specifies the RAM-16GDR4-LD-2133 part number?

Yes, the supplier lists this module as compatible with that exact QNAP part number.

My motherboard has four 288-pin DDR4 slots — can I add this 16 GB stick alongside my existing memory?

The module is a standard 288-pin DDR4 UDIMM, so it will physically install in any DDR4 slot; check your board manual for maximum capacity per slot and total system limit.

Does the CL15 timing at 2133 MT/s require any voltage change in the BIOS?

The module operates at the standard 1.20 V, so no voltage adjustment is needed; the system should apply the correct timing automatically.
