The issue at hand isn’t really needing a golden sample CPU to run those speeds as much as it is needing the board to play nice with the memory and sub timings. I experienced this first hand with my previous Z690 board. I had decided to upgrade to a DDR5 board and decided to go with the Gigabtye Z690 Gaming X after having the DDR4 version of the same board and not having any issues with it. To my surprise the DDR5 variant couldn’t even run my DDR5 at it’s rated 6400Mhz speed without needing to go into the BIOS and manually set a bunch of timings and voltages. This is in contrast to the DDR4 version running perfectly fine no tinkering needed.
I returned the Gigabyte board and opted for an ASUS board and my same CPU (which as a middling rating of 68) was able to boot and run just fine by enabling XMP at 6400Mhz. No further fiddling required. I’m able to even run this kit at almost 7000Mhz by tinkering with it a bit.
The point I’m trying to make is that it isn’t the CPU as much as it’s the boards themselves. Even DDR5 7000Mhz only requires a 1750Mhz memory controller clock in gear 2. And virtually any CPU can do that with ease. It’s not till you cross the 1900-2000Mhz memory controller speed that you start depending on your CPUs imc quality. That’s around the 7600Mhz DDR5 range where it’ll start to matter for the CPU.
