This article covers crucial デスクトップ用増設メモリ 32GB(16GBx2枚)DDR5 5200MT.

Overview

The Crucial CT2K16G52C42U5 is a DDR5 desktop memory kit designed for mainstream users. It offers 32GB of total capacity in a 2x16GB configuration, running at 5200MT/s with a CAS latency of CL42. This places it firmly in the entry-to-mid-range segment of the DDR5 market. Compatible with Intel 12th through 14th Gen Core processors (LGA1700) and AMD Ryzen 7000 series (AM5) platforms, this kit provides a cost-effective way to adopt DDR5 memory. Crucial, as a brand of Micron, is known for reliable, JEDEC-standard memory modules that work out of the box without tweaking. For users building a new DDR5 system on a budget, the CT2K16G52C42U5 delivers solid performance at a reasonable price point. It's a straightforward, no-frills option that prioritizes stability and compatibility over extreme speeds.

Compatibility Guide

This memory uses the standard 288-pin UDIMM form factor, which fits any desktop motherboard with DDR5 DIMM slots. Key compatibility points include: Socket support: LGA1700 (Intel) and AM5 (AMD) Memory standard: DDR5-5200 (PC5-41600) Form factor: UDIMM (288-pin) Voltage: 1.1V (standard DDR5) Since this kit operates at JEDEC standard speeds, it does not require XMP or EXPO profiles to reach 5200MT/s. Simply install the modules in the recommended slots (usually A2 and B2 on a 4-slot board) and the system will automatically run at the rated speed. Note that mixing this kit with other DDR5 modules may cause the system to run at the lowest common speed.

Product Info

The Crucial CT2K16G52C42U5 was released in late 2022 and is widely available through major retailers like . It comes with a limited lifetime warranty from Crucial, reflecting the brand's confidence in its reliability. Market positioning: This is an entry-to-mid-range DDR5 memory kit. The 5200MT/s speed is the baseline for DDR5, and CL42 latency is standard for this speed tier. It's not aimed at overclockers or enthusiasts chasing the lowest latencies, but rather at users who want a dependable, affordable DDR5 upgrade. Capacity: 32GB (2x16GB) Speed: 5200MT/s Latency: CL42 Voltage: 1.1V * Form factor: UDIMM (288-pin)

Best Use Cases

First-time DDR5 builders will appreciate the plug-and-play nature of this kit. Since it runs at JEDEC standard speed, there's no need to enable XMP or EXPO in the BIOS — just install and go. This makes it ideal for pre-built systems or users who prefer a hassle-free setup. Budget-conscious gamers and content creators will find the 32GB capacity sufficient for modern titles and productivity software. The cost savings over faster DDR5 kits can be redirected toward a better GPU or CPU, which often yields more noticeable performance gains. Stability-focused users, such as those building a home server or a workstation for non-overclocked tasks, will benefit from Crucial's reputation for reliability. The JEDEC-standard operation minimizes the risk of memory-related crashes or instability. ## Alternatives
A direct competitor is the Corsair Vengeance DDR5-5200 32GB kit (CMK32GX5M2B5200C40). It features a slightly lower CL40 latency and a more aggressive heat spreader design. However, the Crucial kit is often priced lower and its simpler design reduces the chance of clearance issues with large air coolers. Another alternative is the Kingston FURY Beast DDR5-5200 32GB kit (KF552C40BBK2-32), also with CL40 latency and a heat spreader. Kingston offers a strong compatibility guarantee program. The Crucial kit, being a Micron product, may have an edge in raw component quality and is frequently available at a more attractive price point.

Things to Consider

The 5200MT/s speed is on the lower end of DDR5 capabilities. For gaming, especially with Ryzen 7000 CPUs that benefit from 6000MT/s, you may leave some performance on the table. If you're chasing every frame, a faster kit is worth the extra investment. CL42 latency is standard for 5200MT/s, but lower-latency kits (CL30-CL36) exist at higher speeds. Applications sensitive to memory latency, such as certain simulations or database workloads, may show a difference. For general use and gaming, the impact is minimal. This kit does not support XMP or EXPO profiles, so overclocking beyond 5200MT/s is not guaranteed. If you plan to manually overclock your memory, look for kits with higher speed bins and tighter timings. Finally, if you're considering populating all four DIMM slots, be aware that DDR4 and DDR5 both suffer speed degradation with four modules. For 32GB, a 2x16GB configuration is optimal. If you need 64GB later, consider a 2x32GB kit instead of adding another 2x16GB kit.
