In reading what RAM is supported by a motherboard, what do the following mean? "By JEDEC" and "by A-XMP OC MODE." What do these terms mean, and how do I ensure that the RAM I choose is compatible with whatever these terms are?

1866/ 2133/ 2400/ 2667Mhz (by JEDEC)
2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466 MHz (by A-XMP OC MODE)

Thank you for your help!

What it really means is the JEDEC is what the CPU is officially rated for, but many boards can handle higher end ram, and it GENERALLY works fine with a CPU that's supported by that motherboards chipset.
For example, Ryzen 1k series is only officially rated for 2667 mhz, but actually performs extremely well with 3000/3200mhz memmory, even higher but it's not really cost effective at that point.

Do you need to do anything special to run RAM that is beyond the JEDEC recommended frequencies? 3000mhz RAM in my example above, for example.

I did try Google, btw, thank you. It's not interactive. I'd rather ask humans.

As opposed to the fake people on the rest of the internet? Seems like just laziness to me.
