Kit configuration

This SK hynix kit delivers 16 GB of DDR4 memory across two 8 GB unbuffered DIMMs. The modules run at 2400 MHz with a CAS latency of 17 and operate at the standard 1.20 V. Each stick uses the 288-pin desktop form factor for straightforward installation in compatible motherboards.

System fit

The dual-channel pair suits mainstream desktop builds that need a reliable 16 GB baseline for everyday multitasking, office applications and light content creation. Systems requiring ECC error correction, registered buffering or speeds above 2400 MHz should consider alternative memory.

Ready to install

No extra cables, software licences or heat-spreader accessories are included in the package. The two DIMMs arrive ready to seat in the memory slots, so the only requirement is a motherboard that supports DDR4 2400 unbuffered memory.
