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 white version of the Pro OC series uses Micron D-die IC and Richtek PMIC, the same as the black version. Richtek delivers the most popular PMIC, which is used in most high-frequency gaming and overclocking memory modules. 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 1.5V VDD/VDDQ. However, it didn’t scale well past DDR5-7000, so I decided to lower the voltage and stabilize it at DDR5-7000 CL38.
Overclocking results are exactly the same for four of the memory kits tested in our redaction. Two were black, and two were white. All of them could make DDR5-7000 CL38-45-45 at 1.40V VDD/VDDQ. It’s a respectable result and already a significant improvement over the XMP/EXPO profile. The DDR5-7200 was benchable, but I couldn’t stabilize it at reasonable timings or voltages. The memory kit could post even at DDR5-7600 but couldn’t enter Windows. Considering that all kits acted in a similar way, I’m not sure if there will be one in the current batch that can be stabilized above 7000MT/s, but there is always a chance.
Below is the result made on one of the white Pro OC kits.
Regardless of voltages, it wasn’t possible to set CL32 at 6000MT/s+.The only well-performing alternative is DDR5-6400 CL34-38-38 1.40V. Results for this profile were slightly worse than those for DDR5-7000, but they should be easier to set on lower-series motherboards.
The same as in the previously reviewed Crucial memory kit, if we set tREFI at 65k or higher, we can count on about 5-8GB/s higher bandwidth (depending on the frequency) and 5-12ns lower latency. However, it’s much harder to stabilize RAM at high tREFI, so I left it at auto for comparison purposes.
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 the most popular memory range on modern computers. We still wish to see higher options like 6400MT/s, as the 6000MT/s is already not much more than standard.
