What happens if I disable C states?
The more C states you have enabled, the more aggressively your CPU can throttle down its power usage when it is idle. When it detects computer activity (a hardware interrupt), it will throttle back up to C0 (full power state). If you disable C states, your CPU will be in C0 state all the time.
What is disable C state?
Disabling C-States will prevent your processor from going into a low power state and will significantly increase idle power consumption.
Should I disable global C state?
Global C-states being off has the most impact, but has the potential to stabilize Live USB/CDs of most Linux distros. If you run a lot of distros, this is what you should choose. zenstates.py only disables C6, allowing inactive cores to downclock more to provide more “budget” to the single loaded core.
What is the C state?
C-states are states when the CPU has reduced or turned off selected functions. Different processors support different numbers of C-states in which various parts of the CPU are turned off. … Processors may have deeper C-states that are not exposed to the operating system.
What states start with C?
C
- California.
- Colorado.
- Connecticut.
What is Package C state limit?
Package C State Limit:
Specifies the lowest C-state for the processor package. This feature does not limit the processors to enter any of the core C-states. This default setting is “No Limit”, all C-States supported by the processor are available. If set to “C0”, no package C-state support.
How do I disable C1E in BIOS?
Disable CPU Power Management
- During the boot process, press the Delete or Entf button (depending on your keyboard layout) to enter the BIOS.
- Switch to -> Advanced CPU Configuration -> Advanced Power Management Configuration.
- Change Power Technology to Custom and Energy Efficient Turbo to Disable.

Should I disable SpeedStep?
While it is safe to disable speedstep, it is not something I would recommend doing. Speedstep increases or decreases CPU frequency based on CPU load, and it can be a saver of electricity and also reduces heat and noise of the PC, by slowing down the CPU when it is not being stressed.
What is CFG lock in BIOS?
CFG-Lock is a setting in your BIOS that allows for a specific register(in this case the MSR 0xE2) to be written to. By default, most motherboards lock this variable with many even hiding the option outright in the GUI.
Should I enable C1E?
If you are not going to enable C3, C6, C7 then you should enable C1E if you want to reduce heat and power consumption. Best to enable all of them for maximum savings. Many people recommend that when overclocking that you should disable the C states.
How do I check my CPU C-state?
Method 1
- Method 1. By booting with the kernel command line argument processor. max_cstate=0 the system will never enter a C-state other than zero.
- You can add these variable in your grub2 file. Append “processor.max_cstate=0” as shown below.
- When we set a tuned profile with force_latency=1.

What is NX mode in BIOS?
NX Mode: Similar to Intel eXecute Disable (XD), AMD BIOS calls it No eXecute bit (NX); a technology used in processors to prevent execution of certain types of code.

It’s basically virtualization. With SVM enabled, you’ll be able to install a virtual machine on your PC…. let’s say you want to install Windows XP on your machine without uninstalling your Windows 10. You download VMware for example, take an ISO image of the XP and install the OS through this software.
Should I disable core performance boost?
The maximum boost speed is attainable using the Precision Boost feature that uses AMD’s algorithms to increase the CPU’s frequency when it needs it. Disabling Precision Boost means that the processor can no longer boost its frequency, so it is never running at a higher frequency than its base clock speed of 3.6GHz.
