This article covers Crucial 64GB DDR5 RAM 5600MHz (または5200MHzまたは4800MHz) ノートパソコンメモリ SODIMM 262ピン Intel Core UltraおよびAMD Ryzen 8000以上に対応.

Overview

The Crucial CT64G56C46S5 is a 64GB DDR5 SO-DIMM memory module from Micron’s consumer brand, designed specifically for modern laptops and small-form-factor systems. Running at 5600MT/s with CAS latency 46, it targets Intel Core Ultra (and 14th-gen) and AMD Ryzen 8000-series platforms, offering the highest memory bandwidth available in mobile configurations today. With a single module capacity of 64GB, this stick enables tasks that were previously limited to desktop workstations—running multiple virtual machines, editing 8K video, or processing large datasets—all from a laptop. Micron’s vertical integration ensures exceptionally high reliability and validation. Pricing sits in the mid-to-high range for laptop memory, but given the 5600MT/s speed and 64GB density, it offers strong value against slower 4800MT/s alternatives. It’s an ideal upgrade for creative professionals and power users who need maximum multitasking headroom on the go.

Compatibility Guide

Form factor: 262-pin SO-DIMM, compatible with any laptop or mini-PC that uses standard DDR5 SO-DIMM slots. Memory standard: DDR5 only. Not backward-compatible with DDR4 slots or platforms. Supported platforms: Intel Core Ultra (100-series and newer), 14th-gen Core, AMD Ryzen 8000-series or later. Older chips (e.g., 12th-gen Intel, Ryzen 7000) may physically work but are not officially validated and may run at reduced speeds. XMP/EXPO: Fully supports Intel XMP 3.0 and AMD EXPO for automatic overclocking to 5600MT/s where the system allows.

Product Info

Crucial CT64G56C46S5 is built by Micron, one of only three global DRAM manufacturers with over 45 years of memory engineering expertise. Each module undergoes rigorous component and module-level testing. It carries a limited lifetime warranty and is readily available through major retailers like . In the market, it sits as a mid-to-high tier product, appealing to those who need the combination of high density and high speed without stepping into the premium RGB or heatsink-sealed territory.

Best Use Cases

Creative Professionals: Video editors, 3D artists, and photographers who regularly work with large files. 64GB allows smooth multitasking with multiple Adobe apps open simultaneously. However, pure gamers may find 32GB sufficient and can save money. Developers & Data Scientists: Running multiple containers, compiling large codebases, or handling big-data preprocessing. 64GB significantly reduces out-of-memory errors. For basic web development, 32GB is more cost-effective. * High-End Road Warriors: Users with premium laptops (e.g., Dell XPS, Lenovo ThinkPad P series) that have replaceable SO-DIMMs and need maximum performance on the road. The 5600MT/s speed pairs perfectly with recent Intel and AMD mobile CPUs.

Things to Consider

This is a SO-DIMM module and will not fit desktop DIMM slots. Always verify your system’s memory format before purchasing. 64GB is overkill for most users. If you mainly browse, stream, or game, 32GB (16GB×2) offers better value and lower latency. To achieve 5600MT/s, your laptop’s CPU and motherboard must support DDR5-5600. Otherwise, the module will automatically downclock to 5200 or 4800 MT/s. Mixing this module with a different brand or speed may cause instability. For best results, buy a matched pair or a dual-channel kit. ## FAQ
Q: Can I use this memory with an Intel 13th-gen Core laptop? A: Official compatibility lists Intel Core Ultra and 14th-gen or newer. A 13th-gen laptop may physically accept the module and run at lower speeds, but Crucial does not guarantee stability. For best results, pair it with a supported platform. Q: Does this work in a desktop PC? A: No, standard desktop motherboards use DIMM slots. However, some mini-PCs (e.g., Intel NUC, ASUS PN series) and ultra-compact motherboards use SO-DIMM; check your system’s documentation. Q: Can I install two of these for 128GB? A: Yes, if your laptop has two SO-DIMM slots and the CPU/motherboard supports 128GB. Most Intel Core Ultra and Ryzen 8000 laptops support that capacity, but always confirm with the manufacturer’s specs.
