OWC 4GB DDR4 2400 CL17 1.2V Non-ECC UDIMM desktop RAM

4GB DDR4 2400 UDIMM for desktops and NAS

This module delivers 4GB of DDR4 memory at 2400 MT/s with a CAS latency of 17. It uses the standard 288-pin unbuffered DIMM form factor and operates at 1.2V without ECC. The stick is a direct replacement for QNAP part numbers RAM-4GDR4A0-UD-2400 and RAM-4GDR4A1-UD-2400 and fits desktop PCs, workstations and compatible NAS systems.

Sustained throughput at JEDEC standard speeds

Rated at PC4-19200, the memory maintains its 2400 MT/s data rate under continuous workloads rather than only in short bursts. JEDEC compliance ensures stable timing at CL17 across extended sessions. Backward compatibility with 2133 MT/s platforms allows the same module to run reliably at the lower speed when required.

Low-voltage operation keeps thermals modest

At 1.2V the module draws minimal power, which limits heat output during normal use. No heat spreader is fitted, so the bare PCB relies on case airflow for cooling. The low voltage and unbuffered design also contribute to quiet operation without active cooling requirements.
