Before we try increasing voltages I need you to answer some questions about your ram...
Have you been running with xmp enabled or disabled? If enabled, I would try with xmp disabled, but manually set to 5600 MHz instead of 6000 MHz with timings & voltages set to what your ram sticks say on the side of the modules first to see if that helps.
Tried that suggestion and it still hung. I am now using AMD XMP and trying it out so far it did NOT hang so far.......keeping fingers crossed.
