DDR5 4800 SODIMM for laptop upgrade

This 8 GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10 V operation. It uses the standard 262-pin SO-DIMM form factor for laptops, notebooks and all-in-one systems. The unbuffered, non-ECC design matches the PC5-38400 specification. Buyers who need 16 GB or higher single-module capacity should look elsewhere.

Thermals noise and power at stock settings

DDR5 at 1.10 V draws less power than previous generations, reducing heat inside compact chassis. No heat spreader is fitted, so the module relies on the system's existing airflow. Silent operation is assured because there are no moving parts. Systems with constrained cooling headroom benefit from the lower voltage.

Compatible replacement for Corsair part numbers

The module is validated as a direct replacement for Corsair CMSX8GX5M1A4800C40 and CMSX16GX5M2A4800C40 kits. Rigorous testing ensures reliable performance at the rated speed and timings. Lifetime warranty and US-based technical support are included with every order. No additional software or accessories are bundled.

Questions about this item

How do I install the 262-pin DDR5 SODIMM in my laptop, and what step do people often miss?

Power off the laptop, disconnect the battery if accessible, open the memory compartment, align the notch on the 262-pin module with the slot key, insert at a slight angle, then press down firmly until both side clips click — the step many miss is not seating it fully so the clips engage.

What maintenance or replacement will this 8GB DDR5 module need over time?

No routine maintenance is required for this unbuffered non-ECC DDR5 SODIMM; if a memory error appears later, the module itself would be replaced rather than serviced.

What limit appears first when this CL40 4800MHz DDR5 runs under sustained load?

The CAS latency of CL40 at 4800MHz sets the timing boundary, and the fixed 1.10V operating voltage caps headroom before thermal or power limits become a factor.
