Yeah good one, that's a really good vCore for that speed.
You where posting ~1.425v for @5Ghz before. What happen?
Have you discovered something new, that you can share. or you where pushing too much vCore without testing with less before?
EDIT:
Oh I see Chri$ch's point, he just posted while I was writing this. You are running the LinX at 50%, that doesn't mean stable.
