Dimension Scores
The 5600MHz speed is standard for DDR5, but the CL46 latency is on the slower side compared to higher-end DDR5 kits.
It offers broad compatibility with 12th and 13th Gen Intel Core and AMD Ryzen 7000 Series processors, supporting both XMP 3.0 and EXPO.
User feedback indicates limited overclocking headroom beyond the advertised XMP/EXPO profiles.
Crucial is a Micron brand, backed by 42 years of memory expertise and rigorous testing at component and module levels.
Best For
- Users running memory-intensive applications like 4K video editing or large data processing.
- Gamers seeking higher frame rates and reduced lag in demanding titles.
- Desktops with 13th Gen Intel Core or AMD Ryzen 7000 Series processors requiring 64GB of RAM.
- Workstations needing to run multiple applications simultaneously without performance degradation.
Not Recommended For
- Users prioritizing the absolute lowest latency DDR5 for competitive gaming.
- Laptops, as this is a UDIMM desktop memory kit.
- Budget-conscious users who do not require 64GB capacity or DDR5 speeds.
Watch Out For
- The memory's CL46 latency is considered slower than other DDR5 kits, which might affect performance in latency-sensitive applications.
- Some systems may not achieve the advertised 5600MHz speed, potentially downclocking to 5200MHz or 4800MHz, requiring BIOS adjustments.
- Overclocking potential is reported as limited, so don't expect significant speed gains beyond XMP/EXPO profiles.
- Absence of heatsinks could be a concern for users pushing their systems in poorly ventilated cases, despite the low 1.1V operating voltage.

What Buyers Say
Users frequently highlight this Crucial 64GB DDR5 kit as a cost-effective way to get into DDR5 with high capacity, often noting it works without issues right out of the box. Many appreciate the straightforward installation and the performance boost for multitasking and demanding applications. While the CL46 latency is a recurring point of discussion, some users find the real-world performance difference negligible for their use cases, especially when capacity is the priority.
“Needed 64GB for my video editing rig, this Crucial kit just worked, no fuss, and my projects render way faster now, even if the timings aren't the absolute tightest.”
Common Praise
- Provides a substantial 64GB capacity for heavy workloads.
- Works immediately after installation without needing extensive configuration.
- Offers a noticeable performance improvement over DDR4 for multitasking.
- Compatible with both Intel XMP and AMD EXPO for easy setup.
Common Complaints
- The CL46 CAS Latency is higher than some other DDR5 kits.
- Not much room for manual overclocking beyond the rated speeds.
- Some systems might downclock the memory from 5600MHz to 5200MHz or 4800MHz.
- Lacks aesthetic features like heatsinks or RGB lighting.
Ownership Tips
- After a few weeks, the system feels much snappier with multiple applications open, especially virtual machines.
- Enabling XMP in the BIOS was necessary to hit the advertised 5600MHz, otherwise, it defaulted to a lower speed.
- The modules run cool even under load, likely due to the 1.1V operating voltage, so the lack of heatsinks isn't an issue.
- No stability issues encountered after extended use in a Ryzen 7000 system.
Frequently Asked Questions
Is this RAM compatible with my 12th Gen Intel processor?
Yes, this Crucial 64GB DDR5 RAM kit is compatible with 12th Gen Intel Core processors, in addition to 13th Gen Intel Core and AMD Ryzen 7000 Series CPUs.
Can I use this RAM in a laptop?
No, this memory is a UDIMM (Unbuffered Dual In-line Memory Module) designed specifically for desktop systems and is not compatible with laptops.
Does this RAM support Intel XMP and AMD EXPO?
Yes, this Crucial DDR5 RAM supports both Intel XMP 3.0 and AMD EXPO profiles on the same module, allowing for easy optimization of speeds.
What is the CAS Latency of this memory?
The CAS Latency for this 5600MHz kit is CL46.
Will this RAM automatically run at 5600MHz?
The RAM is rated for 5600MHz, but you may need to enable Intel XMP 3.0 or AMD EXPO in your motherboard's BIOS settings to achieve this speed. It can downclock to 5200MHz or 4800MHz if your system doesn't support the higher speeds.
Buying Guide
When buying RAM, you're looking for a balance between capacity, speed, and latency that fits your CPU and motherboard. For DDR5, higher speeds are generally better, but latency (the CL number) also matters; lower CL numbers mean faster response times. Make sure your motherboard supports the specific DDR5 speed and capacity you're buying. You'll also need to enable XMP (for Intel) or EXPO (for AMD) in your BIOS to get the advertised speeds.
Capacity (64GB)
This is how much data your computer can hold in active use. 64GB is a lot, like having a massive desk to spread out all your work, making it ideal for heavy multitasking, video editing, or running complex simulations without hitting a bottleneck.
Speed (5600MHz)
This indicates how quickly the RAM can transfer data. Think of it as the speed limit on a highway; a higher MHz means data can move faster, leading to quicker application loading and smoother system responsiveness.
CAS Latency (CL46)
This is the delay between when the CPU requests data from the RAM and when the RAM delivers it. A lower CL number means less delay, like a shorter wait time at a traffic light, which can be important for tasks where every millisecond counts, such as competitive gaming.
UDIMM 288-Pin
This describes the physical form factor and pin count. UDIMM means it's for desktop computers, and 288-pin is the standard for DDR5 desktop memory. It ensures the RAM physically fits into your motherboard's slots.
Alternatives
If this kit doesn't fit, consider DDR5 kits with lower CAS Latency (e.g., CL30-CL36) for maximum gaming performance, or kits with higher speeds (e.g., 6000MHz or 6400MHz) if your motherboard and CPU support them and you prioritize raw bandwidth.
