Kingston KF556C40BB-16

Overview

The Kingston KF556C40BB-16 is a 16 GB DDR5 desktop memory module designed to enhance system responsiveness for demanding applications, modern games, and multitasking. Running at 5600 MHz with a CAS latency of CL40, it offers higher bandwidth and improved efficiency compared to DDR4 memory. This module supports Intel XMP 3.0 for easy performance tuning and defaults to a stable 4800 MHz speed for straightforward installation.

Key features

• Intel XMP 3.0 certification enables quick and reliable overclocking through preset BIOS profiles without manual timing adjustments
• Plug and Play operation starts at JEDEC-standard 4800 MHz, making it simple for first-time builders to get their system running immediately
• On-die error-correction code (ECC) continuously maintains data integrity, enhancing stability during long creative sessions, large data processing, or competitive gaming
• Low-profile heat spreader efficiently dissipates heat, helping to keep memory temperatures low even in compact or airflow-restricted cases
• Operates at a power-efficient 1.25 V, balancing performance with reduced energy consumption
• Single 16 GB module leaves room for future memory expansion by keeping additional DIMM slots free

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
