Capacity and form factor

This is a 64GB dual-channel kit built from two 32GB DDR4 SO-DIMM modules. Each stick uses a 260-pin layout and runs at 2666MHz with CL19 latency. The kit is designed for notebooks that accept unbuffered, non-ECC memory.

Before ordering

Verify that your laptop supports DDR4 SO-DIMM modules and has two free slots for a dual-channel configuration. Confirm the motherboard can address 32GB per slot and operates at 1.2V. Check whether the BIOS recognises 2RX8 organisation without a firmware update.

Build integration

The two modules populate a standard dual-channel pair, leaving no additional slots occupied on a typical two-slot board. Unbuffered operation means no registered buffer delay, and the 1.2V rating keeps power draw within normal DDR4 limits. No ECC function is present, so the kit suits standard consumer workloads.

Questions about this item

Does the 64GB kit include both 32GB modules or must the second stick be bought separately?

The kit contains two 32GB modules, giving a total of 64GB in one package.

Should I choose the CL19 2666MHz version or a different latency for my notebook?

This kit runs at CL19 and 2666MHz; select it when your system specifies DDR4-2666 with that latency.

What does the 2666MHz rating mean once the memory is installed in a laptop?

It indicates a maximum data rate of 2666 MT/s, delivering PC4-21300 bandwidth when the platform supports it.
