Should I disable C states

Knin3 · 9 May 2025 at 19:14

Om trying to fix a fault with outlast trials, fatal error, read on a forum disabling c states helps n fixed it for one person. Anyhoo ive got 2 options, c state and enhanced. Ive just disabled c state but stopped short with enhanced bcus of a scary warning by the bios. I just see on another forum someone mentioned to enable c states but disable enhanced. Please if anyone has any help I would really appreciate it

Thankyou

You should not need to disable C-States, because ultimately if it fixes the issue your CPU / motherboard are not fully stable at low load.

That said, as a troubleshooting step, there's nothing to be worried about. It won't do any harm.

Generally: yes, there's no harm in it. But, be aware it can impact (increase) power consumption of the CPU in idle/light load.

Can you tell us your motherboard please? I don't know what "enhanced" means without reading the manual.

My guess is that it means the CPU is allowed to reach deeper sleep states, which is why it had a warning (because that can cause issues with some systems and power supplies).

From what I can gather in the manual, it is just a deeper sleep state. You can safely disable both.

If your CPU is not stable with C-States enabled, I'd want to check for other symptoms, e.g.:

If its faulty why are you trying to do everything to "fix" it rather than doing an RMA?

For the amount they cost I would be sending it back for a replacement
