Hello, the link above shows the 5.35 oc I have.

Bios settings (bit more time to fiddle around) are

Core multiplier: 50

Avx offset : 0

Blck: 107

Vcore set to adaptive

Target voltage : 1.200

Offset voltage : 0 (Idk why but this gives 1.36 volts all said and done)

Ring ratio either auto or 47

Vdroop : disabled

IGPU: disabled

Enhanced C states enabled

Idle temp is 30°c (this is in a room ambient temp ~ 85°F)
At load peak on Ada64 after an hour or two 72°c on core #6 (seems to be my hot core) and 62 - 67 °c other cores.

Cooling is a single 480 radiator. Also I liquid cooled the vrm(s) otherwise they get above 113°c and begin thermal throttling. Just added a second 480 rad but am waiting on an rma for my ram (you can see in the link thar I am only running 3 4gb sticks one was doa)
