This is not a required step to build your home lab. It’s just an extra step that will give you a slight performance boost if you want it. Obviously you should know that modifying any of these BIOS settings can break your system and I nor Supermicro are responsible for it. I’m providing this as a reference on how I did it for my setup.

Overclocking the Supermicro
Reboot and enter the BIOS
Reboot the device either by sshing into esxi and typing “reboot” or by resetting the power button on front of the Supermicro. Upon reboot, press F11 to enter the Aptio Setup Utility BIOS screen. (I don’t have any screenshots of this, but it’s pretty straightforward.)
Modify CPU Settings
There are 2 settings that I adjusted to increase my clock speed.
- cTDP Control setting from default of 55W to 75W
- Determinism Slider from default of Auto to Performance
To modify these, navigate to the Advanced Tab, then select CPU Configuration. You will see the 2 options for cTDP and Determinism Slider, modify them to the settings listed above.
That is it. Save the settings and exit the BIOS.
