Capacity and compatibility

This 16GB DDR4 SODIMM module operates at 2666MHz with CL19 latency and 1.20V standard voltage. It is built as a direct replacement for the Crucial CT16G4SFS8266 part number. The unbuffered, non-ECC design targets laptop, notebook, and all-in-one systems that accept 260-pin DDR4 memory.

Build integration

The module fits any 260-pin DDR4 SO-DIMM slot and draws power at the standard 1.20V, so no special voltage handling is required. Because it is unbuffered and non-ECC, it works with mainstream consumer platforms that do not support registered or error-correcting memory. Verify your system's maximum supported speed and capacity before installation to ensure the module runs at its rated 2666MHz.

Capacity headroom

A single 16GB stick doubles the typical 8GB baseline and gives comfortable headroom for multitasking, browser-heavy workflows, and light content creation. Systems limited to one slot or a 16GB maximum will reach their ceiling with this module. Buyers who need more than 16GB total or who require ECC error correction should look for a different configuration.

商品問答

What is the CAS latency of this DDR4 2666 MHz SODIMM?

The module runs at CL19 latency, which is the standard timing for DDR4 2666 memory operating at 1.20V.

How much heat does a 1.20V DDR4 SODIMM produce during continuous all-day operation?

At the standard 1.20V DDR4 voltage, heat output is low; the unbuffered module relies on passive cooling inside the laptop chassis.

Does my laptop need a 260-pin DDR4 slot to accept this 16GB module?

Yes, it requires a 260-pin DDR4 SO-DIMM slot; the module is non-ECC and unbuffered, matching standard laptop memory sockets.
