The memory kit is available in a standard version without heatsinks and RGB backlight, which many users will find advantageous.
The new memory kit is rated at DDR5-6400 and uses one JEDEC profile at CL52-52-52 1.10V. This means that the motherboard uses this profile, and we don’t have to set anything in the BIOS or enable any additional profiles. As you can see on the screenshot, our motherboard sets timings at CL52-51-51. It doesn’t matter much, as the memory kit is fully stable and also overclocks pretty well at the default 1.10V voltage.
The Crucial CUDIMM is available only as a two-module, 32GB kit. We must wait a few weeks to see a higher-capacity version. Crucial is the first manufacturer to release CUDIMM to the retail market, and surely, they won’t stop at one option.
Below is the list of timings at the 6400MT/s profile on our test rig.
As mentioned, the clock driver is supported only on the latest Intel Z890 motherboards, and Crucial adds info on the package. It’s not sure when other platforms will support it.
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 higher frequencies out of the box. Crucial plays safe, and it’s enough for most users. The programmed profile is not slow, but the competition offers much higher frequencies, and Crucial also has more interesting options in the Pro Overclocking series.
We will look closer at the package and memory modules on the next page.
