32GB DDR4 2666 SO-DIMM

This Patriot Signature Line module provides 32GB of laptop memory in a single 260-pin DDR4 SO-DIMM. It operates at 2666MHz (PC4-21300) with CL19 latency and 1.20V power draw. The unbuffered, non-ECC design targets standard notebook upgrades.

Suits notebooks needing a single 32GB stick

Buyers whose laptop only accepts two smaller modules instead of one large stick should look elsewhere. Systems limited to lower DDR4 speeds or different form factors cannot use this module. Platforms requiring ECC or registered memory are not supported.

32GB single-module capacity

The 32GB density in one SO-DIMM slot is the specification that decides fit. If the laptop’s chipset or BIOS does not recognise a 32GB unbuffered DDR4 module, the upgrade will not work.

Questions about this item

Does the 32GB DDR4 2666 SO-DIMM come as a single stick or a kit, and is anything else needed to install it?

The module is a single 32GB 260-pin DDR4 SO-DIMM. No extra parts are required; it installs directly into a compatible laptop memory slot.

Should I choose this 32GB CL19 module or look for a lower-latency version for my laptop?

This Signature Line stick runs at 2666 MT/s with 19-19-19-43 timings at 1.20V. Pick it when you need maximum capacity per slot; lower-latency kits usually offer less capacity per module.

What does the 2666 MT/s rating mean once the RAM is inside my laptop?

The memory operates at 2666 MT/s (PC4-21300) with CL19 latency. The system memory controller will run it at this speed or at the highest supported speed if the platform limits it.
