X13SRA-TF BIOS overclocking function and XTU setting

Overclocking can be accomplished using Intel XTU software as well as through the BIOS. For high-core processors like the w9-3495X, it is recommended to adjust the overclocking setting using the By Core Usage method. For voltage, maintain the Adaptive setting to allow the motherboard to manage it.

To access the overclocking function on the X13SRA-TF, enter the BIOS interface and locate the Overclocking feature in the advanced settings. This can be used to make overclocking adjustments for the processor, mesh/ring, uncore, voltage, and more.

For power management, set the BIOS to Maximum Performance, configure the current limit to the maximum value of 1FFF, and adjust PL1 and PL2 to 800.

Since the highest wattage of the available test platform power supply is limited to 1000W, this setting represents the upper limit of the current platform power supply wattage. The air-cooled radiator can effectively manage the temperature of the w9-3495X with this configuration.
