This article covers crucial 16GB DDR5-5600 SODIMM CL46(16Gbit) CT16G56C46S5.

Overview

The Crucial CT16G56C46S5 is a 16GB DDR5-5600 SO-DIMM memory module designed for laptops and mini PCs. With a data rate of 5,600 MT/s and a CAS latency of CL46, this stick delivers standard DDR5 performance while maintaining reliable operation at 1.1V. As an entry-level DDR5 upgrade option, it suits users moving from DDR4 systems who want to experience the higher bandwidth and improved efficiency of the latest memory technology. This single 16GB module can be paired with an identical unit to run in dual-channel mode, further boosting memory bandwidth for demanding tasks. Crucial backs the module with a limited lifetime warranty, offering peace of mind over years of use.

Compatibility Guide

The CT16G56C46S5 uses the SO-DIMM form factor (260-pin) and is compatible only with laptops or small-form-factor PCs that have DDR5-capable memory slots. The module operates at the standard JEDEC voltage of 1.1V and includes an onboard PMIC (Power Management IC), so no manual motherboard adjustments are required. Before purchasing, verify that your laptop’s memory is socketed and not soldered to the motherboard. For best results when using two modules, try to obtain sticks from the same production batch.

Product Info

Crucial, a brand of Micron Technology, is known for reliable memory products. The CT16G56C46S5 launched in late 2022 and remains widely available through major online retailers. Pricing on Japan is approximately ¥35,800 (subject to fluctuation), placing it in the standard range for DDR5 SO-DIMMs. The limited lifetime warranty covers manufacturing defects for the life of the product, adding long-term value. In the market, this module occupies an entry-level position for DDR5 notebook upgrades, offering a straightforward path to faster memory performance.

Best Use Cases

Light users who want to quickly upgrade their DDR5-capable laptop for snappier multitasking and faster application loading. Users planning to eventually reach 32GB but starting with a single 16GB stick to spread the cost. * Casual gamers and content creators who need reliable DDR5 memory in a portable form factor for moderate workloads.

Things to Consider

This SO-DIMM module will not fit in desktop motherboards; it is strictly for laptops and mini PCs with SO-DIMM slots. With a CAS latency of 46, the module’s access time is higher than low-latency DDR4 kits, so raw memory responsiveness may not be drastically better in some scenarios. Running a single stick limits the system to single-channel memory bandwidth, which can reduce performance in bandwidth-sensitive applications like integrated graphics or heavy multitasking. For optimal throughput, we recommend purchasing two identical modules to enable dual-channel operation. Finally, market prices for DDR5 fluctuate; consider comparing with alternative models if latency is a priority.
