OWC 32GB DDR4 3200 UDIMM

This 32GB DDR4 3200 CL22 module is a non-ECC unbuffered DIMM built to JEDEC standards. It targets desktop PCs, workstations and compatible NAS systems needing a straightforward capacity increase. The 288-pin 1.2V design matches OEM specifications for reliable integration.

DDR4 3200 backward compatibility limits

The module runs at 3200MHz PC4-25600 with CL22 latency and will downclock to 2133MHz, 2400MHz, 2666MHz or 2933MHz when the platform requires it. Maximum throughput is bounded by the DDR4 3200 interface and the memory controller of the host system. No heat spreader is fitted, so airflow in the chassis manages thermals.

Replaces QNAP RAM-32GDR4S0-UD-3200 and T0

This stick is a direct replacement for QNAP part numbers RAM-32GDR4S0-UD-3200 and RAM-32GDR4T0-UD-3200 with identical specifications. The upgrade is worth it when the device supports 32GB per slot and the workload benefits from the added capacity over smaller modules. OWC testing aims to meet or exceed the original manufacturer specs.

Perguntas sobre este artigo

Should I choose the 32GB DDR4-3200 CL22 module or a different capacity?

This module provides 32GB in a single 288-pin UDIMM running at 3200MHz with CL22 timing; select it when your board has a free slot and you need that exact density.

What does the 3200MHz rating deliver once the DIMM is installed?

The memory operates at DDR4-3200 (PC4-25600) with CL22 latency at 1.2V, giving the bandwidth and timing specified for desktop, workstation and NAS platforms.

Which interface does the 288-pin UDIMM use and what speed ceiling applies?

It uses the standard DDR4 288-pin unbuffered interface and will run at 3200MHz or down-clock to 2933MHz, 2666MHz, 2400MHz or 2133MHz depending on the system.
