Socket LGA1700 will work with 12th, 13th, and 14th gen, although 13th and 14th gen may require a BIOS update if it’s an earlier production model.

The upcoming 15th gen will be a new socket, so it won’t work on this motherboard.

Set PL1 and PL2 in the BIOS

I’d keep MCE off to enforce the stock power limits and make sure its not doing black box stuff to the voltage. For testing purposes, you can manually do everything MCE does.

Do you have MCE enabled? It’s usually enabled by default on Asus boards if using the AIO_PUMP 3-pin header, and can cause this type of behavior with cranked up voltages. Just booting up my stock 13900K with MCE enabled resulted in >1.6v until I promptly disabled it.

Screenshots would be helpful, otherwise this is all subjective. Can you also post screenshots for Cinebench R23?

You can get four DDR5 sticks working without any issues. However, you will have to significantly reduce the frequency to get it stable.

If you need 64 GB, you should consider getting a 2x32 or 2x48 GB kit, as 2x dual-rank sticks are easier than four sticks.
