Hey Squid, Thanks for having a look for me.
I've gone through and double checked my bios settings. Power Supply Idle Control was set to Auto, but it is now set "typical current idle" if I read that FAQ correctly.
As for the RAM, here's what is in the machine: https://nemixram.com/128gb-4x32gb-ddr4-3200-pc4-25600-ecc-udimm-memory/
While there isn't an XMP profile present, I will go ahead and let everything to set on what it decides to boot at (Auto). For what it's worth, it did pass 4 passes of memtest86 with simply setting the Frequency to 3200MT.
I'll let you know how things go, thanks again for the suggestions!
