OWC 16GB DDR4 2666 ECC SODIMM 2x8GB CL19 1.2V memory upgrade

OWC 16GB DDR4 2666 ECC SODIMM kit

This 16GB kit contains two 8GB DDR4 2666 ECC unbuffered SODIMM modules built for ASUSTOR AS6504RD, AS6504RS, AS6508T, AS6510T and AS6512RD systems. It targets NAS owners who need error-correcting memory for data integrity in micro-server or point-of-sale workloads. Buyers who need non-ECC memory for consumer laptops or who require higher capacities than 16GB should look elsewhere.

Installing the 260-pin modules in compatible

The modules follow the standard SODIMM form factor and seat in the memory slots without tools. Because the kit is JEDEC-standard and ROHS-compliant, it meets OEM specifications for a warranty-safe upgrade. Installers must ensure the chassis is powered down and discharge static before handling the sticks; the only common issue is forgetting to press both retention clips fully until they click.

Sustained operation at 2666MHz with CL19 latency

Under continuous load the ECC circuitry detects and corrects single-bit errors, helping maintain data integrity during long file transfers or database tasks. The 1.2V operating voltage keeps power draw low in always-on NAS enclosures. Backward compatibility with 2400MHz and 2133MHz systems allows the kit to run at lower speeds if the platform requires it.
