16GB DDR4 2400MHz desktop module

This single 16GB DDR4 2400MHz CL17 DIMM operates at 1.2V and uses a standard 288-pin unbuffered non-ECC design. It serves as a direct replacement for the Crucial CT16G4DFD824A module in compatible desktop PCs, workstations and NAS systems.

JEDEC and ROHS compliant build

The module meets JEDEC standard PC4-19200 specifications and ROHS requirements, ensuring a warranty-safe upgrade path. Backward compatibility with 2133MHz systems allows installation in older platforms without configuration changes.

16GB capacity for multitasking headroom

A 16GB module lets you open more applications and larger files simultaneously while reducing swap-file activity. The single-DIMM layout leaves additional slots free for future expansion when the platform supports higher total memory.

Questions about this item

Will this module fit a desktop motherboard that uses 288-pin DDR4 slots?

Yes, the stick is a 288-pin unbuffered DIMM built to the JEDEC DDR4 standard, so it seats in any desktop board with DDR4 slots.

Can I add this 16 GB stick alongside existing 2133 MHz memory?

The module runs at 2400 MHz but is backward compatible with 2133 MHz, so it will down-clock automatically to match slower sticks.

Does the memory require ECC support or a registered slot?

No, it is non-ECC and unbuffered, the standard configuration for consumer desktop motherboards.
