16 GB DDR4 ECC UDIMM for NAS and servers
This 16 GB DDR4 2400 module runs at PC4-19200 with CL17 latency and 1.2 V operation. It is an unbuffered ECC DIMM designed for workstations, servers and NAS systems such as Synology RackStation units. The single 288-pin stick provides error-correcting memory for data-critical workloads.
Suits ECC-capable platforms needing 2400 MHz
Systems that require registered or load-reduced DIMMs cannot use this module. Builds without ECC support in the chipset or CPU will not benefit from the error-correction feature. Non-ECC consumer desktops and laptops should look for standard unbuffered DDR4 without ECC.
Verify motherboard accepts DDR4 2400 ECC
Check that the platform supports 288-pin DDR4 at 2400 MT/s with ECC and unbuffered operation. The module is backward compatible with 2133 MHz buses. Confirm the number of available slots and the maximum capacity per slot before ordering.
