4GB DDR4 SODIMM for Laptops

This 4GB DDR4 260-pin SODIMM module upgrades compatible laptops, notebooks and all-in-one systems. It runs at 2400 MHz with a CAS latency of 17 and operates at the standard 1.20 V. The unbuffered, non-ECC design targets everyday computing and multitasking workloads.

Straightforward Slot Installation

Installation requires opening the memory compartment, aligning the 260-pin key with the slot, and pressing firmly until the retention clips engage. The most common issue is a loose fit caused by not seating the module fully, which prevents the system from recognising the memory.

DDR4 2400 Bandwidth Ceiling

The PC4-19200 interface caps maximum throughput at the rated 2400 MT/s, so faster DDR4 modules will downclock to this speed when mixed. Systems limited to lower DDR4 frequencies will also restrict the module to the slower supported rate.
