48GB DDR5 5600MHz laptop upgrade

This 48GB DDR5 5600MHz SO-DIMM module targets users who need more capacity for multitasking and demanding workloads on a laptop or all-in-one system. It delivers 48GB in a single stick running at PC5-44800 speeds with CL40 latency.

Check DDR5 SO-DIMM slot and voltage

Before ordering, confirm your system accepts 262-pin DDR5 SO-DIMM memory and supports 1.10V operation. The module is non-ECC and unbuffered, so it must match the motherboard memory controller requirements for that configuration.

Standard DDR5 thermals and power

Operating at the standard 1.10V DDR5 voltage, the module runs without a heat spreader and relies on the laptop chassis airflow for cooling. Power draw stays within the DDR5 specification for a 48GB unbuffered SO-DIMM at 5600MHz.

Questions about this item

What comes in the box and do I need anything else to install it?

The box contains one 48GB DDR5 5600MHz CL40 SO-DIMM module. No extra parts are required if your laptop has a free 262-pin DDR5 slot.

Should I choose the 48GB module or a 16GB kit instead?

Pick the single 48GB module when you need maximum capacity in one slot; choose a 16GB kit if your system only supports 16GB per slot or you prefer dual-channel with two sticks.

What does the 5600MHz rating actually give me in daily use?

The 5600MHz speed (PC5-44800) delivers the standard DDR5 data rate at 1.10V, so your laptop runs at its rated memory bandwidth without overclocking.
