Side note: Do you really need to run at full power? 275mhz isn't that bad....
What do you mean "full power" .... -0.0366v stock setting?
If so, 275mhz at that voltage would cause no harm, extremely inefficient but harmless.
Its running -0.0366v or HIGHER at 325mhz on all dies in a single cube which is dangerously close to meltdown of those connectors.
