These are part of a new generation of DDR5 modules that add a clock driver to the module itself, rather than relying entirely on the clock signal coming all the way from the CPU's memory controller. That is expected to significantly change the game for DDR5 overclocking, and expectations based on the limitations of configurations lacking the clock drivers may not be accurate. I expect we'll see 6+ months of firmware tuning before we have a clear picture of what each platform is ultimately capable of, but early on the focus will be on Intel platforms.
