OWC 64GB DDR4 2666MHz CL19 8x8GB SODIMM 1.2V laptop RAM

64GB DDR4 SODIMM kit for laptops and NAS

This kit supplies 64GB of DDR4 memory across eight 8GB modules running at 2666MHz with CL19 latency. It targets owners of compatible laptops, all-in-one PCs, mini desktops, micro servers and NAS appliances who need the maximum supported capacity for heavy multitasking or virtualisation workloads.

Fits 260-pin DDR4 slots without a heat spreader

Each module uses the standard 260-pin SO-DIMM form factor and operates at the JEDEC 1.2V level, so it draws no more power than the factory memory it replaces. The low-profile design clears tight chassis spaces and leaves room for factory cooling solutions in compact systems.

Runs at 1.2V with backward speed compatibility

The modules are rated for 2666MHz at 1.2V and will automatically clock down to 2400MHz or 2133MHz when installed in platforms that only support those lower speeds. This JEDEC-compliant behaviour keeps thermals and power draw consistent with the original system specification.
