8 GB DDR4 2400 SO-DIMM

This 8 GB DDR4 2400 SO-DIMM module provides a straightforward capacity increase for laptops that accept 260-pin unbuffered memory. It suits owners of compatible notebooks who need more headroom for everyday multitasking and standard productivity workloads. The single-rank 1Rx8 organisation keeps the electrical load light on the memory controller. Systems limited to 1.20 V DDR4 operation will recognise the JEDEC-standard timings without manual adjustment.

Sustained workload behaviour

At the rated 2400 MT/s speed and CL17 latency the module delivers consistent throughput during extended sessions such as large spreadsheet recalculations or background compilation jobs. The 1.20 V operating voltage helps maintain thermal stability inside confined laptop chassis when the memory controller runs continuously. Unbuffered signalling avoids the extra cycle penalty that registered designs introduce under prolonged access patterns. The PC4-19200 bandwidth ceiling remains steady rather than throttling after a short burst.

Upgrade context

This module replaces an existing 4 GB or 8 GB DDR4 SO-DIMM when the platform has a free 260-pin slot or when the current stick is the only one installed. The jump is worthwhile when the system currently swaps to storage during typical workloads or when the manufacturer specifies 2400 MT/s as the maximum supported frequency. Buyers whose laptops require ECC or registered memory cannot use this unbuffered non-ECC part. Systems already populated with faster DDR4 that down-clocks to 2400 MT/s will not gain additional bandwidth from this module.
