32GB DDR4 SO-DIMM laptop upgrade

This 32GB module uses the 260-pin DDR4 SO-DIMM form factor and runs at 3200 MT/s with CL22 timings. It is built for notebooks that accept unbuffered, non-ECC memory at 1.20V. The single stick adds a full 32GB of capacity in one slot.

DDR4 SO-DIMM speed and voltage limits

The module operates at 1.20V and is rated for 3200 MT/s with 22-22-22 timings. It will downclock to 2933 MT/s or 2666 MT/s if the platform only supports those lower speeds. Bandwidth and power improvements are tied to the DDR4 standard itself.

Single 32GB stick capacity constraint

This kit provides 32GB in a single rank, so total system memory depends on how many SO-DIMM slots your laptop exposes. Buyers who need more than 32GB must verify that a second slot is free and supported by the chipset.

Questions about this item

Should I choose this single 32GB module or a kit of multiple modules?

This listing is a single 32GB DDR4 3200 CL22 SODIMM. Adding a second identical module enables dual-channel bandwidth if your laptop has two slots.

What does the 3200 MT/s rating mean once the module is installed?

It runs at up to 3200 MT/s and can downclock to 2933 MT/s or 2666 MT/s if the system only supports those speeds.

What does the 260-pin DDR4 SO-DIMM interface cap in practice?

The 260-pin DDR4 SO-DIMM form factor fits standard laptop slots and operates at 1.20V, delivering PC4-25600 bandwidth at the rated CL22 timings.
