Capacity and fit

This is a single 32GB DDR5 SO-DIMM built for laptop and all-in-one systems that accept 262-pin modules. It targets users who need more memory for multitasking and heavier workloads without replacing an entire kit.

What to verify first

Check that your device supports DDR5 at 4800MT/s and uses unbuffered non-ECC SO-DIMMs running at 1.1V. The module is a 2Rx8 rank configuration, so confirm your motherboard can address that organisation and that a free slot is available.

Build integration

The stick plugs directly into a standard 262-pin DDR5 SO-DIMM socket and draws power at the JEDEC 1.1V level with no heat spreader required. It leaves other slots open for additional upgrades and adds no height clearance concerns in thin chassis.

Questions about this item

Does the 32GB DDR5-4800 SO-DIMM ship as a single stick or a kit, and is any extra hardware required?

The listing is for one 32GB module (1 x 32GB). No additional parts or accessories are needed — just an available 262-pin DDR5 SO-DIMM slot.

How do I decide between the 32GB module and the Kingston KF548S38IBK2-64 64GB kit it replaces?

Choose the single 32GB stick if you have one free slot and want to add 32GB. Choose the 64GB kit (2 x 32GB) if you need 64GB total or want dual-channel performance from a matched pair.

What does the 4800 MT/s speed and CL40 latency mean for everyday laptop use?

At 4800 MT/s (PC5-38400) with CL40 timing and 1.10V, the module runs at standard DDR5 JEDEC settings, giving stable, plug-and-play bandwidth for typical workloads without manual tuning.
