8GB DDR5 4800 SODIMM Upgrade

This 262-pin DDR5 module delivers 8GB at 4800 MT/s with CL40 latency and 1.10V operation. It uses unbuffered, non-ECC architecture and major-brand chips for broad laptop compatibility. The stick is a direct replacement for Crucial CT8G48C40S5 and CT2K8G48C40S5.

Suits laptops with a free DDR5 SODIMM slot

Owners of notebooks or all-in-one PCs that accept standard DDR5 SO-DIMMs can add capacity with this single 8GB module. Systems that only support DDR5 at lower speeds, that require ECC or registered memory, or that have no user-accessible memory slot will not be compatible.

Speed rating: DDR5 4800 (PC5-38400)

The module runs at 4800 MT/s with a CL40 timing profile at the standard 1.10V DDR5 voltage. If your platform demands a different data rate, a lower CAS latency, or a voltage outside the DDR5 baseline, this part will not meet that requirement.

Questions about this item

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

Align the notch on the module with the slot key, press firmly until the side clips click, then verify 4800 MHz in BIOS — many forget to seat both clips fully.

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

No scheduled maintenance is required; if errors appear, run a memory test and replace the stick — DDR5 includes on-die ECC for background correction.

What limit appears first when this CL40 1.10V module runs sustained workloads?

Thermal throttling can trigger before bandwidth limits, as the 1.10V unbuffered design relies on the laptop's cooling to dissipate heat during prolonged use.
