Hey there!

The question would be regarding my 2x8 HyperX 2666Mhz RAM, that I'm currently using with XMP profile in a H370M Pro4 mobo from ASRock.
I'm changing to a B660M PRO RS, which supports up to 4800 DDR4.
I have zero experience with motherboards that have a higher frequency support than my current memory's.
I'm guessing it will default to 2666 Mhz if I enable XMP on the new mobo, since that's how much the memory is capable of.
However, my concern with the usual excitement before arrival is, wouldn't the XMP profile "OC" it to a higher Mhz than the memory can actually take and potentially even kill it?
Might be a dumb question, I might not even have to use XMP on the new mobo to get the most out of the RAM, I'm just genuinely curious, since I don't want to damage anything.
I hope I explained it adequately.

Thanks in advance for every answer!

Have a nice day

Thank you for the answers!
One more question that I'd have:
If I were to get something like a 3733 Mhz RAM in the future, would it default to that, or would it run at 3733 after enabling XMP?
Would I perhaps have to manually tweak it?
