Crucial Pro Overclocking DDR5-6000 CL40 64GB (2x32GB)

Manufacturer: Crucial

The Crucial Pro Overclocking DDR5-6000 is a 64GB dual-module desktop memory kit built around the DDR5 standard, targeting systems that can take advantage of higher-frequency operation through profile-based overclocking. It ships as a 2x32GB configuration in a 288-pin DIMM form factor, making it compatible with standard ATX and mATX motherboards that support DDR5. The kit includes an integrated heatsink to assist with thermal management during sustained workloads, while omitting RGB lighting in favor of a straightforward, functional design.

Running at a tested speed of 6000 MHz with primary timings of CL40-40-40-80, the kit achieves a true latency figure of 13.3 ns at its rated frequency. The SPD base speed is set at 5600 MHz, with the full 6000 MHz profile accessible via Intel XMP 3.0 or AMD EXPO on supported platforms. Operating voltage is rated at 1.35V. The kit does not use Samsung B-Die and does not support ECC, and module height comes in at 41.4 mm, which may be relevant when pairing with larger CPU coolers.

Pros
  • Supports both Intel XMP 3.0 and AMD EXPO profiles, making it compatible with a wide range of overclock-capable platforms
  • Ships as a 2x32GB dual-channel kit, providing a total of 64GB which suits memory-intensive workloads
  • Includes an integrated heatsink to help dissipate heat during sustained operation
  • Operates at 1.35V, which is within the standard voltage range for DDR5 overclocking kits
  • The 41.4 mm module height is relatively compact, reducing the likelihood of clearance conflicts with large CPU coolers
Cons
  • CL40 timings are relatively loose for a 6000 MHz DDR5 kit, resulting in a true latency of 13.3 ns
  • Does not use Samsung B-Die, which may matter to users who specifically seek that chip type for fine-grained manual tuning
  • ECC is not supported, ruling it out for workstation or server environments that require error-correcting memory
  • No RGB lighting, which limits visual customization options for builds where aesthetics are a priority
Who is this for?

This kit is well-suited for desktop users running platforms that support Intel XMP 3.0 or AMD EXPO, as these profiles allow the full 6000 MHz speed to be activated without manual tuning. The 64GB total capacity makes it a practical fit for users who regularly work with memory-intensive applications such as video editing, 3D rendering, or large dataset processing. The integrated heatsink and standard 1.35V operating voltage also make it a reasonable choice for users who want a set-and-forget overclocking experience without additional cooling considerations.

Who is this NOT for?

Users who require ECC memory support — such as those building workstations or servers where data integrity is critical — will find this kit unsuitable, as it does not offer error-correcting functionality. Enthusiasts focused on aggressive manual overclocking may also find the kit limiting, since it does not use Samsung B-Die chips, which are commonly preferred for that purpose. Additionally, users building compact systems such as small form factor or NUC-style machines should note that this kit uses a full-size 288-pin DIMM form factor, which is incompatible with platforms requiring SO-DIMM modules.

Performance:

true latency 13.3 ns
memory speed (Tested Speed) 6000
memory speed (SPD) 5600 MHz
DDR memory version 5
CAS Latency (CL) 40

tRCD timing 40
tRP timing 40

The Crucial Pro Overclocking DDR5-6000 operates on the DDR5 standard with a tested speed of 6000 MHz, while its SPD base frequency is set at 5600 MHz. Primary timings run at CL40-40-40-80, covering CAS Latency, tRCD, tRP, and tRAS respectively, which places the true latency at 13.3 ns at the rated frequency.

General info:

form factor 288-pin DIMM
memory size (total) 2 x 32GB
has Samsung B-Die ✕
voltage 1.35V
height 41.4 mm
memory size 32GB

This kit uses the standard 288-pin DIMM form factor and consists of two 32GB modules for a total capacity of 64GB. Each module operates at 1.35V and stands 41.4 mm tall, which is worth checking against CPU cooler clearance. The kit does not use Samsung B-Die memory chips.

Features:

Intel XMP / AMD EXPO Intel XMP 3.0, AMD EXPO
Supports ECC memory ✕
Has an integrated heatsink ✓
has RGB lighting ✕

The kit supports both Intel XMP 3.0 and AMD EXPO profiles, allowing the rated frequency to be enabled on compatible platforms through the motherboard BIOS. An integrated heatsink is included to help manage heat during operation. The kit does not support ECC memory and does not feature RGB lighting.

Final Verdict

The Crucial Pro Overclocking DDR5-6000 is a straightforward DDR5 kit aimed at desktop users who want a substantial memory upgrade without the complexity of manual overclocking. Its dual-platform profile support via Intel XMP 3.0 and AMD EXPO means that reaching the rated 6000 MHz speed is as simple as enabling a BIOS setting, and the 64GB total capacity gives it genuine headroom for demanding workloads. The CL40 timings and absence of Samsung B-Die do place some limits on how far enthusiast-level tuning can realistically go, and the lack of ECC rules it out for data-critical environments. For users who prioritize capacity, ease of setup, and broad platform compatibility over fine-grained overclocking flexibility, this kit represents a well-rounded and capable option within the DDR5 desktop segment.
