Those settings verify and for the life of me I cannot go higher then 45x. Whatever I do when I start to benchmark at 46x+ it immediately shuts down. Even if I put the core voltage at 1.3 1.4 1.5 no matter what it shuts down within 1 second. I don't see any thermal throttling. I can't tell if it's the VRM shutting down or what's going on. I have tried no xmp , lower cache settings, 1.8-2.1 input. Speed step on and off, blck at 125 and lower multiplier, nothing works.
Any ideas as to why it is shutting down when going beyond 45x?
Note when doing 46x at 1.269 volts it BSOD and I am thinking the voltage was too low but when I raise it to even 1.299 it shuts down. I can't tell if it's a bios issue when the voltage goes to high or what. I don't see any temps over 75 so far.
