48GB DDR5 5600 SO-DIMM

This Crucial DDR5 Classic module delivers 48GB of laptop memory at 5600 MT/s with CL46 latency. It uses the 262-pin SO-DIMM form factor and runs at 1.10V. The stick is unbuffered, non-ECC and has no heat spreader. It is sold as a single-channel unit for straightforward capacity upgrades.

Suits 12th and 13th Gen Intel Core

The module is validated for 12th and 13th Gen Intel Core and AMD Ryzen 6000 Series laptops. It is not for systems that require ECC or registered memory. It is not for users who need a matched multi-channel kit. It is not for platforms that do not support DDR5 SO-DIMMs.

48GB single-module capacity

The 48GB capacity on one SO-DIMM lets you reach high memory totals with fewer slots. This is the decisive spec when your laptop has limited slots or when you want maximum capacity without populating every socket.

Questions about this item

Should I choose the 48GB DDR5 5600 CL46 module or a lower-capacity kit for my laptop?

This single 48GB module fills one SO-DIMM slot and leaves the second slot free for a matching stick later, while a two-stick kit uses both slots immediately.

What does the DDR5 5600 rating mean for actual throughput in a laptop?

The module runs at 5600 MT/s with CL46 latency, delivering the PC5 44800 bandwidth rating your CPU's memory controller can utilise.

Does the 262-pin DDR5 SO-DIMM interface limit the speed compared to desktop DIMMs?

The 262-pin SO-DIMM form factor carries the same DDR5 5600 signal; the laptop's memory controller, not the pin count, determines the maximum stable rate.
