Crucial CT2K32G48C40U5 64GB DDR5 4800MHz Desktop RAM

Name: Crucial CT2K32G48C40U5 64GB DDR5 4800MHz Desktop RAM
Brand: Crucial
SKU: CT2K32G48C40U5

Overview

The Crucial 64GB DDR5-4800 Desktop RAM Kit pairs two 32GB UDIMM modules to deliver a substantial memory upgrade for DDR5-compatible desktop systems. Operating at 4800MHz with CL40 timings, this kit meets the JEDEC baseline specification for DDR5, ensuring broad compatibility with Intel and AMD platforms that support the standard. The 1.1V operating voltage represents a meaningful efficiency improvement over DDR4's typical 1.2V, reducing power consumption and heat output under sustained workloads.

With Intel XMP 3.0 support, users on compatible motherboards can apply tuned memory profiles without manual BIOS configuration. The 64GB capacity makes this kit well-suited for content creators working with video editing, 3D rendering, and large project files, as well as power users who run multiple virtual machines or keep dozens of browser tabs and applications open simultaneously. As a Crucial product backed by Micron, the kit benefits from direct access to DRAM manufacturing and testing, offering a dependable foundation for systems stepping into the DDR5 generation.

Pros & Cons

👍 Pros

64GB total capacity handles memory-intensive workloads like video editing, large datasets, and heavy multitasking
DDR5 architecture provides higher bandwidth and lower voltage (1.1V) compared to DDR4
Intel XMP 3.0 support enables easy one-click overclocking on compatible platforms
Two-module kit runs in dual-channel mode for optimal memory throughput

👎 Cons

Requires a DDR5-compatible motherboard and processor — not usable in DDR4 systems
CL40 latency is higher than many DDR4 kits, though DDR5 compensates with greater bandwidth
4800MHz speed is the DDR5 baseline — faster DDR5 kits are available for users who want peak performance
No ECC support limits its use to consumer desktops rather than workstation or server applications

Frequently Asked Questions

How many modules are included in this kit?

This kit includes two 32GB DDR5 UDIMM modules for a total of 64GB.

Is this RAM compatible with DDR4 motherboards?

No, DDR5 uses a different 288-pin design and is not backward compatible with DDR4 motherboard slots. Your motherboard must support DDR5 memory.

Does this kit support Intel XMP 3.0?

Yes, it is Intel XMP 3.0 enabled, allowing compatible motherboards to apply optimized memory profiles automatically.

What voltage does this DDR5 kit operate at?

It operates at 1.1V, which is lower than typical DDR4 voltage, contributing to improved power efficiency.

Does this kit include ECC error correction?

This kit is non-ECC. While DDR5 includes on-die ECC at the chip level, this module does not support full ECC functionality required by server or workstation platforms.
