48GB DDR5 5600MHz SODIMM

This 48GB DDR5 5600MHz CL40 SODIMM module upgrades laptops, notebooks and all-in-one computers that accept 262-pin DDR5 memory. It replaces G.Skill F5-5600S4645A48GX1-RS and F5-5600S4645A48GX2-RS parts with an unbuffered, non-ECC design running at 1.10V. Buyers who need ECC or registered memory cannot use this module.

CL40 latency at 5600MHz

The single specification that decides fit is the CL40 CAS latency at the DDR5 5600 (PC5-44800) data rate. Your system must support this exact speed and timing combination; a different latency or a lower DDR5 speed will not match the G.Skill modules this part replaces.

Thermals and power in normal use

Operating at the standard 1.10V DDR5 voltage, the module draws minimal power and generates little heat without a heat spreader. Typical laptop cooling handles the thermal load silently during everyday workloads.

Questions about this item

What does the 5600 MHz rating mean once this module is installed in a laptop?

The module operates at DDR5 5600, delivering a PC5-44800 data rate in any laptop that supports DDR5 5600 SO-DIMMs.

How does the DDR5 SO-DIMM interface limit performance in practice?

The 262-pin DDR5 SO-DIMM form factor caps the module at DDR5 5600 speeds and 1.10 V, so it cannot exceed that transfer rate in a compatible system.

What physical slot and clearance does this 48 GB stick require?

It needs a single 262-pin DDR5 SO-DIMM slot and has no heat spreader, fitting standard laptop memory bays.
