Should I enable or disable C-states?
C state is used for power saving and when you overclock you use the maximum power of the CPU, constantly. So you would not want to use c state. Disable both, also manual vcore always, adaptive might do some adjustments you don’t want to happen. First off an overclocked processor does not use maximum power constantly.
What is C state control?
C-states control the sleep levels that a core can enter when it is idle. C-states are numbered starting with C0 (the shallowest state where the core is totally awake and executing instructions) and go to C6 (the deepest idle state where a core is powered off).
What are C states Intel?
C-states are idle power saving states, in contrast to P-states, which are execution power saving states. During a P-state, the processor is still executing instructions, whereas during a C-state (other than C0), the processor is idle, meaning that nothing is executing.
