This article covers Crucial RAM 16GB DDR5 5600MHz (5200MHzまたは4800MHz) デスクトップメモリ CT16G56C46U5 ブラック.

Overview

The Crucial CT16G56C46U5 is a single 16GB DDR5-5600 desktop memory module built by Micron's in-house engineering. Designed for modern platforms such as Intel 13th Gen Core (Raptor Lake) and AMD Ryzen 7000 series, it runs at up to 5600MHz while being backward-compatible to 5200MHz and 4800MHz. This module targets users who need reliable, affordable DDR5 memory for everyday multitasking, light content creation, or as a starting point for a dual-channel upgrade later. With a standard 1.1V operating voltage, it remains cool even in compact builds.

Compatibility Guide

The CT16G56C46U5 is a 288-pin UDIMM designed for desktop motherboards with DDR5 support. It works seamlessly with Intel XMP 3.0 and AMD EXPO profiles, allowing easy downclocking to match CPU/motherboard limitations. The module is single-rank (1Rx8) and non-ECC, so it is intended for standard consumer platforms. For peak memory bandwidth, two identical modules should be used in dual-channel configuration; a single stick halves the effective bandwidth. Always check your motherboard's QVL list for confirmed compatibility, though Crucial's compatibility tool is also available on their official site.

Product Info

Released as part of Crucial's standard DDR5 lineup, the CT16G56C46U5 offers 16GB capacity at 5600MHz with CAS latency 46. It is a non-ECC, unbuffered module running at 1.1V. Market positioning is firmly in the mid-range segment – it prioritizes cost-effectiveness and broad compatibility over extreme low-latency performance. Crucial typically provides a limited lifetime warranty (registration may be required). Pricing places it among the more affordable DDR5 options, making it an attractive entry point for DDR5 adoption.

Best Use Cases

Budget DDR5 Builds: If you're assembling a first DDR5 PC and need to keep costs down, this single stick lets you start with 16GB and add a matching module later for 32GB dual-channel. Productivity & Light Creative Work: For tasks like web browsing, office applications, and even 1080p video editing, 16GB at 5600MHz offers snappy responsiveness. The low voltage means less heat, benefiting silent or small-form-factor builds. Upgraders on a Tight Budget: Users who already own a DDR5 motherboard but are running on lower-speed DDR5 (e.g., 4800MHz) can drop in this module to gain a moderate speed boost without replacing the entire platform.

Things to Consider

This is a single-module kit; to achieve dual-channel memory bandwidth you must purchase two identical sticks. While CL46 is standard for DDR5-5600, competitive gamers may prefer tighter timings (CL30–CL34) found in premium kits, though those come at a higher price. Also, some early DDR5 motherboards may not stable run 5600MHz out of the box; updating the BIOS is recommended. If your workload consistently exceeds 16GB (e.g., heavy 3D rendering, multiple VMs), consider starting with a 32GB kit instead.
