128GB DDR4 ECC SODIMM kit
This OWC kit supplies 128GB of DDR4 memory in four 32GB modules for laptops, all-in-one PCs and NAS units that accept 260-pin SO-DIMMs. The ECC unbuffered design targets systems that can use error-correcting memory for data integrity.
Sustained-load behaviour
Rated at 2666MHz with CL19 timings and 1.2V operation, the modules maintain JEDEC-standard performance during extended workloads in compatible micro servers or NAS devices. Backward compatibility with 2400MHz and 2133MHz platforms allows the kit to run stably at lower speeds when the host system requires it.
Deciding specification
The 260-pin DDR4 ECC unbuffered form factor is the single detail that determines whether this kit fits; systems needing non-ECC, registered or a different pin-count memory cannot use these modules.

Questions sur cet article
How much power does the 1.2V DDR4 2666MHz CL19 kit draw during continuous all-day operation?
The modules run at 1.2 V with a CL19 latency; DDR4 at this voltage is designed for low power draw in laptops and NAS units, though exact wattage depends on the host system's memory controller and workload.
What must my laptop or NAS already support to use this 260-pin ECC SODIMM kit?
The system needs four DDR4 SO-DIMM slots, 260-pin connectors, and a memory controller that accepts unbuffered ECC modules at 2666 MHz (PC4-21300) with 1.2 V operation.
Will these 32 GB sticks down-clock reliably if I keep my older 2400 MHz or 2133 MHz modules installed?
Yes — the kit is backwards compatible with 2400 MHz and 2133 MHz speeds, so it will run at the lowest common frequency when mixed with slower DDR4 modules.
