I tried setting the bclk to 155 and raised the voltage up to 1.15 and, no chance, still booting to black screen.
I'm not looking for something too high since I only have a noctua nh l9i for cooling right now (i'm pretty limited in space)
150 bclk with everything enabled. C-State, SpeedStep...
I can push it a bit further by setting my multiplier to 21 and it seems to be stable too (somehow)
Currently, I'm using the igpu, maybe I need a dedicated gpu to get higher right?
