16 GB DDR4-2666 SODIMM for notebooks

This 16 GB DDR4-2666 CL19 module uses the standard 260-pin SO-DIMM form factor and runs at 1.20 V. It is built for notebooks that accept unbuffered, non-ECC memory at this speed and latency.

Check your notebook manual for DDR4 SO-DIMM support

Verify that the laptop accepts 260-pin DDR4 modules at 2666 MT/s and does not require registered or ECC memory. The slot must be keyed for standard SO-DIMM thickness and operate at 1.20 V.

No accessories or software included

The module ships without a heat spreader, driver disc or utility software. Installation relies entirely on the notebook’s firmware detecting the JEDEC-standard timings of 19-19-19 automatically.

Questions about this item

Does the 260-pin DDR4 SO-DIMM arrive as a single 16 GB stick or do I need to buy a second module for dual-channel?

The KVR26S19D8/16 is a single 16 GB module; add a second identical stick if your notebook has two slots and you want dual-channel bandwidth.

My laptop only supports DDR4-2666 CL19 — is this the exact speed and latency combination I need?

Yes, the module runs at DDR4-2666 (PC4-21300) with CL19 19-19-19 timings at 1.20 V, matching that specification exactly.

Will the CL19 latency at DDR4-2666 actually improve responsiveness in my ASUS TUF FX504 compared to slower memory?

At DDR4-2666 CL19 the kit delivers the standard bandwidth and latency for that platform; real-world gain depends on the workload and whether the CPU memory controller can utilise the full 2666 MT/s rate.
