Enabling XMP profile leading to troubles starting the PC = Possible Bad RAM module?

My RAM was running at 2133Mhz rather than 3200mhz, from a quick search I read to enable XMP profile. But it seemed enabling XMP profile caused troubles starting up. Does this mean the unit is faulty or is it normal to take a few tries to start up? Though the RAM is stable when used at 2133mhz.

I had tried enabling XMP profile a week or two ago and the PC went into a reboot loop for a while until starting in safe boot. I tried disabling XMP profile and it instantly was able to start up like normal again. It asked do you want to also apply settings to the processor(adequate processor cooling required), I don't remember but I think I may have chosen Yes. My processor isn't OC enabled as it's an i7-7700. I chose a Z motherboard to allow higher RAM speeds but choose locked CPU as benchmark results for games I play suggested 7700 would be sufficient & I won't need to overclock, but the open world games I like do benefit from fast RAM. By the time I need to upgrade I assume it's likely it'll be necessary to do a rebuild. I think this is when hex core/octa core become standard with all cores fully utilized, quad core being below recommended and GTX 1080 being below recommended GPU power.

I tried it again today except selected No as I was thinking that may have been why I couldn't start up the other time. This time it failed to start 1 time and then it worked.

Now I am planning when finances allow to outright replace this RAM anyways since it's only 8GB as the other module didn't work at all(Pretty sure can't RMA as I bought it in 2016 and built PC last month). If after buying and installing a new 16GB(8x2 DDR4) RAM set I still experience difficulties successfully starting with XMP enabled does that mean I would have potentially bad RAM module(s)?

If yes then I'd like to be prompt about going through the RMA process. I'd at least be able to use my current RAM in the meantime so I won't mind waiting.

Admirable
It shouldn't matter what CPU you have below DDR4 4000 since only than is the BLCK speed changed. Everything below that only changes the memory controller speeds to match the DDR, the best it can. If you are unstable at 3200, you may have to raise the VCCIO and or the VCCSA voltage to get the memory controller stable.

How do I do this? Even with my most recent boot, it seems like system thinks my RAM module is 2132mhz(maybe when it failed to boot with XMP enabled it auto-disabled XMP?)?
