Capacity and fit

This 16GB DDR4 SO-DIMM uses the 260-pin layout standard for modern laptops. The dual-rank 2Rx8 organisation fits a single memory slot and runs at the JEDEC 3200 MT/s rate. It is intended for notebooks that accept unbuffered non-ECC modules at 1.2V.

Sustained operation

The module operates at the standard 1.20V DDR4 voltage, so power draw and thermals remain consistent during extended workloads. CL22 latency is applied continuously rather than only in burst conditions. The PC4-25600 rating reflects the steady-state transfer ceiling.

Build and daily use

SK hynix packages the ICs on a green PCB with gold edge contacts rated for repeated insertion cycles. The unbuffered design means the memory connects directly to the system controller without a register buffer. No heat-spreader is included, allowing the module to fit tight chassis clearances.

Questions about this item

How much heat and power does this 1.20V DDR4-3200 module add when the laptop runs all day?

The module operates at the standard DDR4 voltage of 1.20 V, so its thermal and power contribution stays within the normal envelope for a 16 GB SO-DIMM under continuous load.

What must my laptop already provide for this 260-pin DDR4 SO-DIMM to work?

Your laptop needs a free 260-pin DDR4 SO-DIMM slot that accepts 1.2 V unbuffered non-ECC memory; the module is a single 16 GB stick with a 2Rx8 organisation.

Will this CL22 3200MHz module run alongside slower DDR4 memory already installed?

Yes — when mixed with slower DDR4 modules the system will run all memory at the lowest common speed and the loosest timings present, so this stick will down-clock to match.
