32GB DDR4 2666 Module

This 32GB DDR4 2666 CL19 UDIMM targets desktop PCs, workstations and NAS systems needing a JEDEC-standard memory upgrade. It runs at 1.2V without ECC or a heat spreader and matches the QNAP RAM-32GDR4S0-UD-2666 specification exactly.

Simple DIMM Installation

The 288-pin unbuffered DIMM fits standard desktop slots and requires no tools beyond opening the chassis. Backward compatibility with 2133MHz and 2400MHz systems reduces the risk of speed mismatch. The most common issue is mixing modules with different latencies or voltages, which can prevent the system from posting.

32GB Single-Module Capacity

A single 32GB stick provides substantial headroom for multitasking, large-file editing and virtual machines on platforms that support this density per slot. Capacity limits appear when the motherboard or NAS firmware caps maximum memory per channel or total installed RAM below the module size.
