How did you manage to get PBO to boost to 5.2Ghz? What BIOS revision are you on? I'm right underneath you on the 5800X rankings, and I'm on air, so I doubt I could boost to 5.2GHz SC, just curious how you were able to achieve it, as auto OC maxes out at +200, but I've seen ASUS mobo's with the option to go higher.
