128 GB DDR5 SODIMM kit

This OWC kit supplies 128 GB of DDR5 memory across four 32 GB modules. It runs at 5600 MT/s with CL46 latency at 1.1 V and uses the 262-pin SO-DIMM form factor. The modules are unbuffered, non-ECC and built to JEDEC PC5-44800 specifications for laptops, all-in-one PCs and compatible NAS devices.

Suited for high-capacity upgrades

The 4 x 32 GB layout fills four slots and targets users who need maximum memory for multitasking, large datasets or virtual machines. Systems with fewer than four SO-DIMM slots or those limited to lower total capacity cannot use the full kit. Buyers needing ECC, registered modules or speeds beyond 5600 MT/s should look elsewhere.

No extra accessories included

The package contains only the four memory modules. There are no heat spreaders, installation tools, software licences or cables. Installation relies on the host system’s standard SO-DIMM slots and the buyer’s own anti-static precautions.
