48GB DDR5 SODIMM for Laptops

This 48GB DDR5 module uses a 262-pin SO-DIMM form factor and runs at 5600MHz with CL40 latency. It operates at the standard 1.10V and is unbuffered non-ECC memory. The single stick suits users upgrading a laptop, notebook or all-in-one that accepts this capacity and speed.

Sustained load behaviour

DDR5 architecture and the 1.10V operating voltage help maintain stable throughput during extended multitasking or heavy workloads. Quality assurance testing verifies dependable performance over time. The module lacks a heat spreader, so system airflow manages thermals during prolonged use.

Upgrade context

This module replaces Kingston KCP556SD8-48, KVR56S46BD8-48, KVR56S46BD8K2-96 and 9905789-124.A00G parts. The jump is worthwhile when your system supports 48GB DDR5 5600 and you need more capacity than smaller modules provide. Buyers needing ECC, registered memory or lower voltage operation should look elsewhere.

Questions about this item

Does the 1.10 V DDR5 module run noticeably hotter or louder than standard laptop memory during all-day use?

The module operates at the standard DDR5 voltage of 1.10 V with no heat spreader, so it produces no more heat or noise than any other unbuffered SODIMM at this spec.

My laptop only has one SODIMM slot — will this single 48 GB stick work on its own?

Yes, this is a single 48 GB 262-pin DDR5 SODIMM rated at 5600 MT/s CL40, so it installs alone in one slot without needing a matched pair.

Will this DDR5 5600 CL40 stick downclock reliably in a system that only supports DDR5 4800?

The module is a standard JEDEC DDR5 5600 part and will automatically run at the highest speed the platform allows, including 4800 MT/s if that is the system limit.
