16 GB DDR4 desktop module

This single 16 GB DDR4 UDIMM runs at 2400 MT/s with CL17 latency and 1.2 V operation. It is an unbuffered non-ECC stick built with major OEM DRAM chips for standard desktop and compatible NAS platforms.

Compatibility check before ordering

Verify that your motherboard or NAS accepts 288-pin DDR4 UDIMM modules at the PC4-19200 speed grade. Confirm the board supports non-ECC unbuffered memory and that a vacant slot is available for the 1x16 GB configuration.

Build quality and daily use

The module has no heat spreader, keeping the profile low for tight slots and allowing direct airflow over the chips. Gold-plated edge contacts on the 288-pin connector resist oxidation and ensure reliable seating through repeated upgrades.

Questions about this item

Will this module fit my QNAP NAS that calls for the RAM-16GDR4A1-UD-2400 part?

Yes, the supplier title lists that exact QNAP part number as compatible, so the 288-pin UDIMM will seat correctly in the NAS memory slot.

Does my motherboard need to support ECC for this stick to work?

No, this is a non-ECC unbuffered module, so it works in standard desktop boards and the listed QNAP NAS without ECC support.

What do the 2400 and CL17 figures mean for everyday use?

2400 MT/s is the data rate and CL17 is the latency; together they set the module at the standard DDR4 2400 performance level for general desktop and NAS workloads.
