The Pro OC memory kit’s white version has the exact specifications as the black one. Both are available in the Crucial store and all large online stores worldwide.
The new memory kit is rated at DDR5-6400 and uses EXPO and XMP profiles at CL38-40-40 1.35V. The regular SPD profile has 1.10V. We wish to see it available at higher capacities, but they are available only as a two-module, 32GB kit. It’s still enough for most users, but more often, we can see that 48GB kits are a better choice if we run multiple applications at once. I’m sure we will see higher capacity kits soon, as Crucial always starts with the lowest and still the most popular one, which is 32GB for the DDR5 series.
DDR5 is mature enough that most available motherboards don’t have problems with RAM compatibility. The Crucial RAM works perfectly with all motherboards we use in redaction and overclocks above the rated specifications. In the last reviews, we used AMD motherboards, as 6000-6400MT/s is perfect for Ryzen processors, which are not scaling well past the 1:1 IMC:RAM ratio. Since we presented overclocked Crucial Pro Overclocking memory in the last reviews, we decided to check the new series on the latest Intel motherboard with the Z890 chipset.
Below is the list of timings at the XMP-6400 profile on our test rig.
All our motherboards with the recent BIOS had no problems with stability or compatibility. Below is an AIDA64 Stability Test. We can use various other stability tests. It’s still good to perform additional tests if we are overclocking to ensure the RAM is stable across multiple test patterns.
We wish to see tighter timings or frequencies that are out of the box. Crucial plays safe, and it’s enough for most users. The programmed profiles are not slow, but the competition offers much higher frequencies, even on the same Micron ICs used in Crucial Pro Overclocking modules.
We will look closer at the package and memory modules on the next page.
