Ln2 cooled, was keeping it between -120° & -130° with voltage at 1.568 (vdroop to 1.468). Using stock voltage with cold it was maxing core at 1350 at 1.3V, same card maxed at 1237 1.3V on water. They like colder.
What does the ULPS actually do, disabling disables the ultra low power state I'm guessing? Haven't played with that one.
SonDa5, the different shader count on the card might not like the new bios that wants to use those extra shaders.
