Overclocking
Disclaimer: Overclocking is never guaranteed, so the results may vary depending on certain conditions and various hardware configurations. I am not recommending overclocking if you do not know what you are doing. High voltages may damage hardware, and the warranty will not cover it.
The whole Crucial Pro OC memory series uses Micron IC, and the 6400MT/s kit is no different. One more thing shared in the whole memory series is a Richtek PMIC. It’s the most popular PMIC used in all overclocking series memory kits. Most motherboards are well-prepared for this PMIC and allow us to use voltages higher than specified.
The tested memory kit worked fine at more than 1.4V VDD/VDDQ. However, it didn’t scale well past DDR5-7000, so I kept the 1.40V voltage and stabilized it at DDR5-7000 CL40.
The overclocking results are similar to those we saw in the last Crucial Pro Overclocking memory review. The Intel Z790 or AMD motherboards are more optimized for this memory. Maybe it’s a matter of early BIOS, as it was easier to set 7000MT/s on the previously reviewed and lower frequency out-of-the-box memory kit.
Below is the 7000MT/s result.
Regardless of voltages, it wasn’t possible to set CL32 at 6000MT/s+.The only recommended alternative is DDR5-6400 CL34-38-38 1.40V, the same as in the 6000MT/s CL36 kit reviewed some months ago. Results for this profile were the same as those for DDR5-7000, but they should be easier to set on lower-series motherboards and better for AMD series.
The Crucial Pro OC RAM maintains the same high quality among multiple kits. It may not be the fastest or best overclocking memory, but it’s easy to stabilize and perfectly fits into modern computers’ most popular memory range. Even though we wish to see higher frequencies, the 6400MT/s is a good addition covering the optimal AMD Ryzen settings.
