Is the High Performance Mode in Windows affecting CPU power saving settings in BIOS?
Hello! Your setup with a 5960x overclocked to 4.5 ghz at 1.3v, manual settings on the Asus X99 Deluxe, and high performance mode in Windows seems to be achieving the desired speed. It appears enabling high performance mode alone is sufficient, but you might also want to check if disabling certain power-saving features in the BIOS could help maintain optimal performance. Let me know if you need more details!
In addition to selecting the high performance mode in the Windows power plan scheme, you should disable Intel speed step and the C wait state option in your BIOS. Ensure that the CPU receives sufficient cooling through the cooling solution. As long as you are certain the CPU is adequately cooled, it is advisable to set a safe shutdown temperature value in the BIOS for the CPU. Also, enable fan warning error reporting in the BIOS and configure it to a reasonable level for any fans connected to the CPU cooler, whether an air cooler or a fan paired with a water cooling loop. This will prevent any downclocking of the CPU core speed and safeguard the CPU in case of a fan failure.

If you are using an air cooler or a fan paired with a water cooling loop for the CPU, this will prevent any downclocking of the CPU core speed. It also safeguards the CPU in scenarios where a fan fails, whether it's an air or water cooling system. This measure protects the CPU and the water pump within the cooling loop.
