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.

商品問答

What is the CAS latency of these DDR4 2666MHz modules under sustained workloads?

The modules run at CL19, which is the rated latency for the 2666MHz speed grade.

How much power does the 1.2V kit draw when the system runs all day?

Each 8GB module operates at the standard DDR4 voltage of 1.2V, keeping power draw low for continuous laptop or NAS use.

Does my laptop need 260-pin SO-DIMM slots to install this 8x8GB kit?

Yes, the kit uses the 260-pin DDR4 SO-DIMM form factor required by compatible laptops, all-in-ones and NAS units.
