Pros
- Achieves 6400MHz speed with tight CL30-38-38-76 timings.
- Supports both Intel XMP 3.0 and AMD EXPO profiles for simplified overclocking.
- Includes advanced on-die ECC for improved stability during operation.
- Features a built-in Power Management IC (PMIC) for optimized energy consumption.
- Equipped with a premium aluminum 1.88mm heat spreader for effective thermal management.
- Illuminates gaming setups with vibrant RGB lighting controllable via Lexar RGB Sync.
Cons
- Some users reported needing to manually enable XMP instead of EXPO to reach advertised 6400MHz on certain AMD motherboards.
- Requires a motherboard and CPU that fully support DDR5 6400MHz speeds for optimal performance.
- RGB lighting customization relies on Lexar RGB Sync software, which may have varying user experiences (no specific complaints found, but a common point of friction for RGB RAM).
- The 1.4V operating voltage is slightly higher than some standard DDR5 kits, potentially generating more heat (though mitigated by the heat spreader).
Dimension Scores
The 6400MHz speed combined with a CL30 latency is among the fastest available for consumer DDR5 memory.
Support for both Intel XMP 3.0 and AMD EXPO standards ensures broad compatibility with current generation platforms.
Designed with XMP 3.0 and EXPO, it's optimized for its rated 6400MHz CL30 speed, with some potential for minor tweaks beyond that for enthusiasts (though not explicitly advertised for further overclocking).
Features like on-die ECC, a built-in PMIC, a 1.88mm aluminum heat spreader, and a lifetime limited warranty contribute to its stability and longevity.
Best For
- PC builders targeting high-refresh-rate gaming with Intel or AMD platforms.
- Users seeking fast memory for demanding applications like video editing or 3D rendering.
- Systems designed for Intel XMP 3.0 or AMD EXPO profiles to achieve advertised speeds.
Not Recommended For
- Budget-focused builds where 6400MHz CL30 performance is not a priority.
- Systems that do not support DDR5 memory modules.
- Users who prefer a stealthy, non-RGB aesthetic for their PC build.
Watch Out For
- On an AMD B650E motherboard, one user had to use XMP instead of EXPO to get the RAM running at 6400MHz.
- The 1.4V operating voltage is higher than the 1.1V base DDR5 standard, requiring adequate case airflow for sustained performance.
- While the heat spreader is 1.88mm thick, the overall module height is not specified, potentially causing clearance issues with large CPU air coolers (no specific user reports found, but a common RAM concern).

What Buyers Say
Users report this 32GB 6400MHz CL30 DDR5 kit delivers on its advertised speeds, with one reviewer noting it as 'some of the fastest RAM' they've tested. The RGB lighting is generally well-received for its aesthetics and manageable size, avoiding clearance issues with CPU coolers. While generally compatible, a specific instance on an AMD B650E board required enabling XMP instead of EXPO to hit the 6400MHz profile. The memory is also noted for its competitive pricing compared to other high-speed DDR5 options.
“Dude, this RAM just *flies* at 6400MHz, my games feel so much smoother, and the RGB actually looks sick, not some cheap glow. Totally worth it, even if I had to poke around in the BIOS a bit for EXPO.”
Common Praise
- Achieves advertised 6400MHz speeds consistently.
- RGB lighting provides a visually appealing aesthetic without being overly large.
- Offers competitive performance for its price point.
- Positive performance in both gaming and application benchmarks.
- Includes a robust 1.88mm aluminum heat spreader for cooling.
Common Complaints
- One user on an AMD B650E motherboard had to manually select XMP instead of EXPO to reach 6400MHz.
- The 1.4V operating voltage is slightly higher than some DDR5 modules, potentially requiring careful system cooling.
- Specific height dimensions are not readily available, which can be a concern for builds with large CPU air coolers (no specific user complaints found, but a common concern for RAM).
Ownership Tips
- The RGB lighting remains consistent and bright even after extended use.
- The heat spreaders effectively dissipate heat, keeping module temperatures stable during heavy loads.
- System stability is maintained even when running demanding applications for hours, thanks to features like on-die ECC.
- The Lexar RGB Sync software is generally straightforward for customizing lighting effects.
Frequently Asked Questions
Is this RAM compatible with my Intel or AMD motherboard?
Yes, this RAM supports both Intel XMP 3.0 and AMD EXPO profiles, making it compatible with a wide range of modern DDR5 motherboards. Always check your motherboard's Qualified Vendor List (QVL) for specific 6400MHz support.
What does CL30 mean for performance?
CL30 refers to the CAS Latency, which is 30 clock cycles. A lower CAS Latency, combined with a high frequency like 6400MHz, indicates faster response times and better overall memory performance.
Can I turn off the RGB lighting?
The RAM features RGB lighting controllable via Lexar RGB Sync software. While not explicitly stated, most RGB software allows for disabling or customizing lighting effects.
Does this RAM have error correction?
Yes, it includes advanced on-die ECC (Error Correction Code) which helps improve stability and reliability by correcting data errors in real-time. This is not the same as full server-grade ECC memory.
What is the physical height of these RAM modules?
The exact height is not specified in the product data, but one review mentioned the modules are 'not too large'. They feature a 1.88mm aluminum heat spreader.
Buying Guide
When buying RAM, you're looking for a balance of capacity, speed, and latency that matches your CPU and motherboard. More gigabytes (GB) mean you can run more programs simultaneously without slowdowns. Speed (MHz) and latency (CL) work together: higher speed and lower latency generally mean faster data access for your processor. Ensure your motherboard supports the RAM's speed and that your CPU can utilize it effectively.
Capacity (32GB)
This is how much data your computer can actively work with at one time. For modern gaming and most productivity tasks, 32GB is a comfortable amount, preventing your system from constantly swapping data to slower storage.
Speed (6400MHz)
This is how many cycles per second the memory can perform. Think of it like the speed limit on a highway; a higher number means data can potentially travel faster between your RAM and CPU.
Latency (CL30)
This is the delay, measured in clock cycles, before the RAM can deliver data after a request. Imagine it as the time it takes for a car to accelerate to the speed limit. A lower CL number means less delay, making the RAM feel more responsive.
XMP 3.0 / EXPO
These are pre-configured profiles that automatically set your RAM to its advertised speed and timings with a single BIOS setting. Without them, your RAM might run at a slower, default speed, like driving a sports car in first gear.
Alternatives
If this kit is too fast or too expensive, look for DDR5 RAM with speeds around 5600MHz to 6000MHz and CL32-CL36 latency. If you need more capacity, search for 64GB (2x32GB) kits at similar speeds.
