<aside> ⚠️ This guide is basic, it is meant for people who have rarely visited their BIOS. There are indeed more comprehensive guides that cover far more features to be disabled, but as someone who has read those guides, these are the settings that have given the people I have worked with the most gains with the least amount of trouble. Thank you.

Optimizing your BIOS can lead to a lot of performance gain in any game, but before we continue ensure you have adequate cooling and a stable system currently.

Normal options to disable:

  1. Intel SpeedStep / AMD Cool'n'Quiet: These technologies adjust the processor's clock speed and voltage dynamically to save power when the system is idle or under light loads. Disabling them ensures that your CPU runs at its maximum clock speed at all times.
  2. C-States: C-States, or CPU sleep states, allow your processor to enter lower power modes when idle. Disabling them will prevent thermal throttling by keeping the processor at a consistent performance level.
  3. Intel Turbo Boost: This technology increase the CPU's clock speed temporarily when under heavy load. Disabling them prevents your CPU from potentially overheating due to increased power draw, but it may also limit peak performance. (Set a Static Overclock on Intel)
  4. Enhanced Intel SpeedStep Technology (EIST) / AMD PowerNow!: These settings allow the CPU to dynamically adjust its clock speed and voltage based on workload. Disabling them ensures consistent performance but may increase power consumption and heat output.
  5. Spread Spectrum: Spread Spectrum is used to reduce the electromagnetic interference (EMI) generated by the system. Disabling it may slightly improve performance but might not have a significant impact on thermal throttling.

SCEWIN

NOTE: These are settings that I have done for people, I will not recommend anything I have not done for people myself.

AMISCE is a command line tool provided by American Megatrends (AMI) for modifying BIOS settings. AMISCE allows you to create or modify the Setup Configuration Data (SCD) file, which contains BIOS settings, and write the modified settings back to the BIOS.

Moving forward from that we can talk about SCEWIN, SCEWIN is an extension of that program which allows us to output and input changes to our BIOS Settings from Windows, and even allows us to change hidden settings we would be otherwise locked out of.

All of the settings I recommend below I will attach the source documents to, I have applied these settings on many systems including some well known aimers such as MattyOW, Cartoon, and others. Some versions of the program won’t support your BIOS, I will attach two, one that is the latest and one that I have found as the most compatible. Some BIOS’s are unwritable using this method, so it won’t work. You have to test and find out, import changes, restart, output, see if the changes are present. If the file does not export, please try one of the other versions and travel in REGEDIT to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system

and ensure “EnableLua” is set to “0”
