Ah, yes, the Super Secret Menu, where my scroll wheel is backwards. Here's an album of various things that seemed relevant:

No sign of short duration power limit, long duration, or cpu current limit. Could be because I'm on a laptop and it has to account for AC and DC power? *shrugs* I found the same 56x/52x values that XTU showed, but they weren't editable in BIOS, or at least they wouldn't save. different numbers
I'm currently testing with Turbo Mode disabled. It was the only thing that jumped out at me as something that could cause minor stability issues to FFXIV with 2 Pcores being 56x and the other 6 being 52x.
Also, while writing this, I rechecked XTU advance view. The two watt settings here are referred to as "short duration" and "extended duration" power limit. Would that be the short and long we're looking for?
Edit: Initial results of Turbo mode disabled: CPU is hold temps around 65-70ºC while playing, used to be sporadic between 70 and 93. The cpu cooling fan has NEVER been so quiet while gaming, I can actually hear the gpu fan. Holding steady at 60 fps. gpu has climbed to 90% usage sometimes but mainly in the 60%'s, not sure if it did before, paid more attention to the cpu before this. cpu usage is only at 15% at most. Did the 7.2 dungeon and desert lvl 100 dungeon for roulettes, same as yesterday. 4 crashes total yesterday within that time, 0 today.
I know that's not comprehensive results when it comes to a random crash, but I'm liking them thus far.
