Windows does not start if the RAM frequency is higher than 2666 MHz, why?

Question

Windows

I bought a new motherboard Gigabyte z590m. The maximum frequency of the RAM in it is 5300 MHz
. My Radeon RAM has a frequency of 3200.
But for some reason, the system does not even start if you set the frequency in the BIOS to more than 2666

Please help, I don’t want to take it to the store. And then again choose the motherboard

Answer 1

Make sure that you set the frequencies exactly through the xmp profile of the RAM. And check the Gigabyte website to see if your memory is on the recommended list.
In addition, the processor must be with the letter K at the end. If not, it may all be in vain.
