Stable XMP profile only sustainable while CPU is overclocked.

Basically this. If I enable the XMP Profile at stock clock speeds I BSOD in Windows, but if I overclock the CPU (currently 4.4 Ghz), it is totally stable.

So, should this concern me?

I also noticed that with the XMP profile the DRAM Voltage is 1.24, but according to the specs for my RAM it should be 1.35 at 3200 Mhz.

Memory controller is in the processor (IMC) so it also gets faster with OC together with caches. OC-ing memory wouldn't do any good without it's controller being OC-ed. It's up to BIOS to read XMP profile in RAM and set things accordingly. Maybe BIOS is to blame for not following XMP explicitly. You can try to adjust RAM voltage manually to 1.35v.
