16GB DDR4 3200 Module

This 16GB DDR4 UDIMM runs at 3200MHz with CL22 latency and 1.2V operation. It is an unbuffered, non-ECC module built to JEDEC standards for desktop PCs, workstations and NAS systems. The 2Rx8 organisation and 288-pin layout match the QNAP RAM-16GDR4T0-UD-3200 specification.

DDR4 3200 Practical Limits

The DDR4 3200 interface tops out at the PC4-25600 data rate defined by JEDEC. Systems that only support 2133, 2400, 2666 or 2933MHz will clock the module down automatically. No higher DDR4 speeds or other memory types are supported by this module.

16GB Capacity Headroom

A single 16GB stick handles everyday multitasking, large documents and moderate creative workloads comfortably. Memory-intensive tasks such as virtualisation, heavy video editing or large in-memory databases will exceed this capacity and require additional modules.

Questions about this item

Should I pick the 16GB DDR4 3200 CL22 2Rx8 module or a different capacity for my desktop?

This module is a single 16GB stick running at 3200MHz with CL22 latency; choose it when your board has a free 288-pin slot and you need exactly 16GB of non-ECC unbuffered memory.

What does the 3200MHz speed actually deliver once the RAM is installed?

The module operates at 3200MHz (PC4-25600) with CL22 timing at 1.2V; your system will run it at the highest speed the motherboard and CPU memory controller both support.

Is the 288-pin DDR4 interface limited to 3200MHz or can it run slower?

The 288-pin DDR4 DIMM is backward compatible and will also run at 2133MHz, 2400MHz, 2666MHz or 2933MHz if the platform requires a lower speed.
