Capacity and fit

This is a 16GB DDR4 SO-DIMM built for laptops that accept 260-pin modules. It runs at 2666MHz with CL19 latency and a standard 1.20V supply. The unbuffered, non-ECC design suits mainstream notebooks and compact workstations. Buyers needing registered or error-correcting memory should look elsewhere.

Sustained workload behaviour

The module operates at the JEDEC-standard 2666MHz data rate under continuous load without requiring a voltage increase beyond 1.20V. CL19 timing provides predictable latency for multitasking and background services. Stability is validated through extended stress testing rather than brief benchmarks. Systems limited to lower memory speeds will clock the module down automatically.

Build and daily implications

Samsung DRAM components are assembled on a standard green PCB with gold edge contacts for reliable slot insertion. The low-profile height fits thin-and-light chassis where taller modules would conflict with the keyboard deck or cooling assembly. Dual-rank 2Rx8 organisation helps populate two-channel controllers efficiently. No heatsink or lighting is included, keeping weight minimal for portable devices.

商品問答

How much heat and power does this 1.20V 16GB DDR4 module generate during all-day use?

The module runs at the standard DDR4 voltage of 1.20V and is unbuffered, so power draw and heat stay within normal laptop SO-DIMM limits for continuous operation.

What must the laptop already provide for this 260-pin SO-DIMM to work?

A free DDR4 SO-DIMM slot that accepts 260-pin unbuffered non-ECC modules at 1.20V.

Will this CL19 2666MHz stick down-clock to match slower DDR4 memory already installed?

Yes, DDR4 modules automatically negotiate the highest common speed and latency supported by the memory controller.
