My CPU officially needs a spot of LLC to be fully stable now. Never overclocked except for running PBO for a while, no manual fuckery otherwise. It's about 5 years old and has seen a lot of use.
I don't know exactly how much extra voltage is going in but if it gets unstable again at these settings, I might have to call it there. Here's to another 3+ years at least.
really fucking happy if this fully fixes it though, I thought I was going to have to buy a new cpu or motherboard to sort it out, which I'd really rather not do
