yea sergio is right, LLC level 2 raises the voltage under load, i mean it could be fine, but its better to use LLC level1 for 24/7.

And the CPU PLL stock is being a bit overvolted, you can decrease it a bit, it might help, 1.6v-1.8v is usually the sweet spot, its a bit more useful when going subzero. You can also try raising it and see if that helps, you just gotta experiment.

The reason i say set BLCK control to enable, is b/c you have no clue what BLCK its going to set. Sometimes even a few mhz can hurt your OC.
