AI Verdict
A 16GB DDR5 5600MHz CL46 UDIMM that provides basic DDR5 functionality for 13th Gen Intel Core and AMD Ryzen 7000 Series systems.
This 16GB DDR5-5600 CL46 module is a functional choice for users building or upgrading a DDR5 system on a budget. Its 1.1V operation and broad compatibility with current Intel and AMD platforms make it accessible, but the CL46 latency is a known compromise for its price point. It's a 'get-the-job-done' option rather than a performance-focused one.
If you need better performance, look for DDR5 modules with a lower CAS Latency (e.g., CL30-CL36) at 5600MHz or higher speeds like 6000MHz.

Cons
- CAS Latency of 46 is considered slow for DDR5-5600 memory in the current market.
- Lacks an integrated heatsink, though user reports indicate it stays cool.
- Single 16GB module, requiring a second purchase for dual-channel operation and 32GB capacity.
- Not designed for aggressive overclocking beyond its rated XMP/EXPO profiles.
Dimension Scores
The 5600MHz speed is standard for entry-level DDR5, but the CL46 latency is high compared to other 5600MHz modules, impacting overall responsiveness.
Offers broad compatibility with 13th Gen Intel Core and AMD Ryzen 7000 Series processors, supporting both Intel XMP 3.0 and AMD EXPO on the same module.
Designed to run at its rated 5600MHz with XMP/EXPO, its 1.1V and CL46 timings suggest minimal headroom for further manual overclocking.
Benefits from Micron's 45 years of manufacturing expertise and includes on-die ECC for long-term stability, tested at component and module levels.
Best For
- New desktop builds requiring DDR5 compatibility with 13th Gen Intel Core or AMD Ryzen 7000 Series processors.
- Users prioritizing cost-effective DDR5 memory for general computing and light gaming.
- Systems where a low 1.1V operating voltage is preferred for power efficiency.
- Upgrading a single 16GB stick in a compatible DDR5 system for increased capacity.
Not Recommended For
- Enthusiast users focused on achieving the lowest possible memory latency for competitive gaming or specific workloads.
- Overclockers aiming to push memory speeds significantly beyond advertised XMP/EXPO profiles.
- Users needing 32GB or more who plan to use four DIMMs on an AM5 platform, which can lead to speed reductions.
Watch Out For
- The CAS Latency of 46 is high compared to other 5600MHz DDR5 kits, which typically offer CL36 or CL40.
- Using four DIMMs on an AM5 motherboard can potentially reduce the stable operating speed to around 4800MHz.
- Absence of a heatsink might be a concern for some users, despite reports of it running cool.
- While compatible with Intel XMP 3.0 and AMD EXPO, users might need to manually enable these profiles in BIOS for rated speeds.

What Buyers Say
Users frequently highlight this Crucial DDR5 module as a cost-effective entry into the DDR5 ecosystem, particularly for new builds. Many appreciate its straightforward installation and reported stability, even without a heatsink. The most consistent point of discussion, however, revolves around its CL46 latency, which is recognized as a trade-off for its budget-friendly price, making it less appealing for performance enthusiasts. It's often seen as a 'no-frills' option that gets the job done without breaking the bank.
“Needed some DDR5 for my new Ryzen 7000 build and this just worked, didn't want to spend a ton, so the CL46 is whatever, it's fast enough for what I do, no fancy lights but who cares.”
Common Praise
- Provides a cost-effective way to get DDR5 memory into a new system.
- Installs easily and works without issues once XMP/EXPO is enabled.
- Maintains stable operation even under heavy workloads.
- Runs cool despite the absence of a dedicated heatsink.
- Compatible with both Intel and AMD platforms using XMP 3.0 and EXPO.
Common Complaints
- The CL46 CAS Latency is notably higher than other DDR5-5600 kits.
- Lacks aesthetic features like RGB lighting or a heatsink, which some users prefer.
- Not suitable for users looking to manually overclock aggressively.
- Some users found the timings were not explicitly listed on retail sites, leading to confusion.
Ownership Tips
- You'll need to go into your BIOS to enable XMP or EXPO to get the full 5600MHz speed, otherwise it might run slower.
- Even without a heatsink, the module doesn't get excessively hot during typical use.
- It's a single rank (1Rx8) module, which can sometimes impact performance slightly compared to dual rank modules in specific scenarios.
- If you buy two single sticks for 32GB, ensure your motherboard and CPU can handle 4 DIMMs at 5600MHz, especially on AM5, to avoid speed reductions.
Frequently Asked Questions
Is this RAM compatible with my motherboard?
This RAM is compatible with desktop motherboards that support DDR5 memory and 288-Pin UDIMM form factor. It's optimized for 13th Gen Intel Core and AMD Ryzen 7000 Series processors.
Do I need to do anything special to get 5600MHz speed?
Yes, you will likely need to enable Intel XMP 3.0 or AMD EXPO in your motherboard's BIOS settings to achieve the advertised 5600MHz speed. Otherwise, it might default to a lower speed like 4800MHz.
Can I use this with DDR4 memory?
No, DDR5 memory is not backward compatible with DDR4 motherboards or memory slots. You must have a DDR5-enabled system.
Is 16GB enough for gaming?
For most modern games, 16GB of DDR5 RAM is sufficient. However, for very demanding titles, heavy multitasking, or future-proofing, 32GB is often recommended.
What does CL46 mean?
CL46 refers to the CAS Latency, which is the number of clock cycles it takes for the RAM to respond to a request from the CPU. A lower CL number generally indicates faster response times, so CL46 is on the higher side for 5600MHz DDR5.
Buying Guide
When buying RAM, you're looking for a balance between speed, capacity, and latency. For DDR5, higher speeds like 5600MHz are a step up from DDR4, but latency (the CL number) also matters. A lower CL number means quicker data access. You also need to ensure the RAM is compatible with your CPU and motherboard, specifically checking for DDR5 support and whether it's a UDIMM (for desktops).
Speed (MHz)
This is how many millions of transfers per second the RAM can handle. Think of it like the speed limit on a highway; a higher number means data can move faster, leading to quicker application loading and smoother multitasking.
CAS Latency (CL)
This is the delay, measured in clock cycles, between when the CPU requests data and when the RAM actually delivers it. Imagine it as how long it takes for a delivery truck to start moving after you place an order; a lower number means less waiting.
Voltage (V)
This is the electrical power the RAM uses. Lower voltage (like 1.1V) means less heat generation and lower power consumption, which can be beneficial for system stability and energy efficiency.
UDIMM (Unbuffered DIMM)
This refers to the type of memory module for standard desktop computers. It means the memory controller is directly on the CPU, offering faster access but without the error correction features found in registered (RDIMM) memory used in servers.
Alternatives
If this module doesn't fit your needs, look for DDR5 RAM with a CAS Latency of CL30-CL36 for better responsiveness, or consider kits running at 6000MHz or higher if your budget and system support it for increased raw speed.
