Capacity and form factor

This 32 GB DDR5 SO-DIMM uses the 262-pin layout and runs at 4800 MHz with a CL40 latency. It is an unbuffered non-ECC module built for laptops, notebooks and all-in-one systems that accept DDR5 memory. The stick operates at the standard 1.10 V and has no heat spreader.

Build integration

The module slots directly into any compatible DDR5 SO-DIMM socket without extra cables or brackets. Its single 32 GB density leaves additional slots free for future expansion where the platform supports more than one module. Systems limited to a single slot gain the full capacity in one step.

Thermals and power

At 1.10 V the module draws minimal power and runs cool enough for thin chassis designs. Passive cooling from the motherboard and case airflow is sufficient under normal workloads. No active cooling or additional voltage headroom is required.

Questions about this item

Will the 4800 MHz DDR5 speed hold under sustained heavy workloads?

The module runs at the JEDEC-standard 4800 MT/s PC5-38400 rating with CL40 latency; it has no heat spreader, so prolonged loads may cause the memory controller to throttle if the laptop chassis cannot dissipate the extra heat.

How much heat and power does a single 32 GB stick draw during all-day operation?

At the standard DDR5 voltage of 1.10 V the module draws minimal power and produces little heat, but without a spreader it relies entirely on the laptop's internal airflow to stay cool during continuous use.

What must my laptop already support for this 262-pin SODIMM to work?

Your system needs a DDR5-compatible SO-DIMM slot, a memory controller that accepts 4800 MT/s PC5-38400 unbuffered non-ECC modules, and BIOS support for 32 GB single-rank or dual-rank 2Rx8 density at 1.1 V.
