Kit Contents and Purpose

This 16 GB dual-channel kit contains two 8 GB DDR5 DIMMs rated at 5200 MT/s with CL40 timings and a 1.25 V operating voltage. It is built for desktop builders who want a straightforward speed upgrade on a modern platform. The black unbuffered modules use standard 288-pin layout and single-rank organisation.

Platform Fit and Limits

The kit carries Intel XMP 3.0 profiles and is validated for Intel 600 and 700 series chipsets including B660, B670, Z690 and for AMD 500 and 600 series chipsets including B550, B650, X570 and X670. Builders whose motherboards only support earlier DDR generations or who need capacities beyond 16 GB should consider other options. Systems requiring ECC or registered memory are not supported.

Deciding Specification

The 5200 MT/s DDR5 speed with CL40 latency at 1.25 V is the single figure that determines whether this kit matches your motherboard’s qualified vendor list and your performance target.

Questions about this item

Does the KF552C40BBK2-16 kit ship as a complete 16 GB pair or must a second DIMM be purchased separately?

The kit contains two 8 GB DIMMs for a total of 16 GB, so no additional modules are required for dual-channel operation.

When should I choose the CL40 5200 MT/s version instead of a faster or slower DDR5 kit?

Select this kit when your motherboard and CPU officially support DDR5 5200 with XMP 3.0 and you want the standard 1.25 V voltage without manual tuning.

What does the 5200 MT/s rating actually deliver once the memory is installed in a desktop system?

The modules run at 5200 MT/s with 40-40-40 timings at 1.25 V when the XMP 3.0 profile is enabled in the BIOS, providing the rated bandwidth on compatible Intel 600/700 series or AMD 500/600 series platforms.
