8 GB DDR4 SO-DIMM for HP notebooks

This 8 GB DDR4-2400 SO-DIMM module upgrades compatible HP EliteBook, ProBook and ZBook mobile workstations. It runs at 1.20 V with CL17 latency and uses a 260-pin unbuffered, non-ECC design. The kit suits users who need extra memory headroom for everyday multitasking on supported HP platforms.

8 GB capacity with DDR4-2400 speed

The single module provides 8 GB of system memory at 2400 MHz (PC4-19200), which handles typical office workloads, web browsing and light content creation. Capacity runs out when running large virtual machines, heavy video timelines or memory-intensive data sets that exceed the 8 GB limit.

Low-voltage operation and RoHS compliance

At 1.20 V the module draws minimal power, helping to preserve battery life and reduce heat output in thin-and-light notebooks. The RoHS-certified, environmentally friendly build contains no hazardous substances, and the lifetime warranty reflects the manufacturer’s confidence in long-term reliability.

Questions about this item

Will this 8 GB DDR4-2400 SoDIMM run in my EliteBook 840 G4 alongside the factory 4 GB stick?

Yes, both modules are DDR4-2400 non-ECC unbuffered SoDIMMs at 1.20 V, so they will operate together at the lower common speed.

How can I confirm the module is running at 2400 MHz with CL17 latency after installation?

Open Task Manager or a tool such as CPU-Z; the memory tab will show 2400 MHz and CAS latency 17 if the system has trained the stick correctly.

Does the package contain only the memory module or are tools or adapters included?

Only the 260-pin SoDIMM is supplied; no screwdrivers, brackets or additional cables are provided.
