DDR4 2400 MHz SODIMM for laptop upgrades

This 4 GB DDR4 module runs at 2400 MHz with CL17 latency and 1.20 V operation. It uses a 260-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The stick is built with major-brand chips and targets AMD and Intel laptop platforms.

Steady throughput for everyday multitasking

At the rated DDR4 2400 speed the module sustains PC4-19200 bandwidth during extended workloads rather than only in brief bursts. CL17 timing and standard voltage keep thermals predictable inside thin chassis. Quality-assurance testing on every unit reduces the chance of errors under continuous use.

Replaces HP 862397-855 when capacity is

Swapping an existing 4 GB stick or filling an empty slot adds headroom for browser tabs, office suites and light creative tasks. The upgrade is worthwhile when the system currently hits memory limits during normal use. Buyers who need more storage or a second module for dual-channel should look elsewhere.

Domande su questo articolo

How much heat and power does the 1.2 V DDR4 2400 module draw when the laptop runs all day?

The module operates at the standard DDR4 voltage of 1.2 V, so power draw and heat output stay low during extended use.

What must my laptop already have for this 260-pin SODIMM to work?

Your laptop needs a free DDR4 SO-DIMM slot that accepts 260-pin modules running at 2400 MHz.

Will this CL17 stick run stably alongside the original HP 862397-855 memory already in my notebook?

Yes, it is a compatible equivalent for HP part 862397-855 and uses the same DDR4 2400 specification.
