So I just upgraded my RAM and wanted to take advantage of the new 3200MHz speed that I could utilize. I normally just turn on the XMP profile in the BIOS, and everything works out, however, I noticed that whenever I did use the XMP profiles, my PC would no longer boot, and finally, I saw this was because I guess my MoBo has some sort of max voltage of 1.2V for the RAM sticks. The RAM I just got with the XMP profile enabled tries to use 1.35V so I think that is the issue. I did not want to run at my old 2666Mhz speed so I just changed the speed to 3200Mhz and everything appears to be fine, but I am just wondering am I losing any kind of benefit or performance from only turning up the speed and not using the XMP profile? (I noticed that with the XMP profile it shows various different timings and also the fact that when enabled it uses 0.15V extra volts).
