I don’t think that results in a failure to boot. Not to mention 64bit addressable space is like 16 QB (though I’m not sure all bits have traces since we’re still orders of magnitude away from being able to use all those bits).
4GB is the 32-bit address space. You could be right. My thought was that there wasn’t really a technical reason to not boot with more RAM than is addressable, but it’s certainly possible that BIOS/firmware or even the OS treated it as a fatal error.

It had reminded me of my old laptop which wouldnt boot if it had more then 4 gb of ram
It may have been 32 bit (dont remember the exact model and no longer have it) or it may have been due to mismatched sticks
