Fair point. I was highlighting that 3000 is the lowest spec AMD suggests, and it’s funny they market these boards with such restrictions while targeting the latest Ryzen models. Regarding the "Voodoo magic," tuning RAM manually can be tricky, which explains why some users managed to get it working despite the manufacturer-imposed limits. It seems the issue often lies with the wrong RAM or motherboard, as AMD advises a minimum of 3000MHz DDR4 dual channel memory for their Ryzen series.
It seems to be off topic and possibly inaccurate. There are many board and RAM pairings capable of exceeding 4000MHz, with around 3600MHz often cited as the optimal range based on testing. I’m not sure what you mean by this. Yes, you can run RAM at advertised speeds using automatic configurations. If that fails, it might be due to user error or incompatible hardware. The wiki isn’t very useful here. With proper equipment and understanding, you can significantly overclock RAM. It’s unclear why the wiki is relevant to this discussion—there are calculators available that could help more effectively.
What are your computer specifications? Which XMP profile are you currently using? It's common for two profiles to function differently, and one may require adjustments. For more details, check the AMD documentation here: [link]. They also suggest a minimum of 3000MHz, so please confirm if this aligns with your setup.
Is this a flawed board layout or a memory controller not suited for 4 sticks? Also, having two sticks might help resolve the issue.

I recall hearing about all that in the initial press releases. Asrock is the only one featuring this table on their boards. I’m curious if it’s mentioned in the CPU user manual, but I’ve noticed the same for Zen and Zen+, so it makes sense this isn’t the issue here.
I'm using a 3900X + GB X570 Aorus Xtreme with 4x XPG D60G DDR4 3200 RAM. It's set to 3334Mhz, though I think I previously enabled XMP in BIOS and later updated it to the latest AGESA 1.0.0.4 F10a version. I also manually adjusted the frequency to 4.475Mhz at 1.375v. I haven't experienced any BSOD or issues when I first connected the board after turning on the XMP profile. The other user has an Aorus Master that should match mine closely.
