If changing memory settings to XMP, my motherboard sets the turbo to sync to all cores which is 3.9GHz on all cores and then my vcore is 1.171v during idle and a bit lower during load due to Vdroop, with vcore on Auto. CPU core temps reached 65C during Intel Burn Test at the Very High setting. Is 1.171v too much for my CPU running at an all core turbo of 3.9GHz? If I get an error in a program or a BSOD should I first blame it on my CPU if it's running at 3.9GHz on all cores?
