16 GB DDR4 2400 module for desktop and NAS

This 16 GB DDR4 2400 CL17 UDIMM is built for desktop PCs, workstations and compatible NAS systems. It runs at 1.2 V and uses the standard 288-pin unbuffered non-ECC layout. The module matches the specifications of QNAP part numbers RAM-16GDR4A0-UD-2400 and RAM-16GDR4A1-UD-2400.

JEDEC and RoHS compliance with lifetime warranty

The memory is 100 % JEDEC-standard and RoHS compliant, making it a warranty-safe upgrade for supported platforms. OWC backs it with a limited lifetime warranty and an advanced replacement program that includes free technical support. Every unit is tested in-house before it ships.

Suits DIY upgraders; not for ECC or registered slots

This kit suits anyone adding 16 GB of standard DDR4 to a desktop or NAS that accepts unbuffered non-ECC UDIMMs at 2400 MT/s or 2133 MT/s. Systems that require ECC, registered or load-reduced DIMMs cannot use this module.

商品問答

Will the 1.2 V DDR4 modules need any voltage adjustment or replacement over time?

The 1.2 V JEDEC standard voltage is fixed; no adjustment is needed and the modules are designed to last the system's lifetime.

What limits sustained throughput on these CL17 2400 MT/s sticks?

The CL17 latency at 2400 MT/s sets the maximum sustained bandwidth the memory controller can achieve.

How much heat and power do the 16 GB unbuffered DIMMs produce during all-day use?

At 1.2 V the modules draw minimal power and run cool enough that no heat spreader is required.
