What is pss support in asrock bios?

In ASRock BIOS, **PSS support** (Processor System States support) is a feature related to Power Saving States for CPUs. PSS allows the processor to enter different power states (also known as C-states) to efficiently manage power consumption and heat generation when the CPU is idle or not heavily utilized. Here are some key points regarding PSS support: 1. **Power Management**: PSS enables better power management by allowing the CPU to reduce its voltage and frequency when full performance is not required, thereby saving energy and reducing thermal output. 2. **C-States**: These are various states of the CPU that indicate how much power it is consuming. The deeper the C-state (for example, C1, C2, C3, etc.), the lower the power consumption and performance. 3. **BIOS Setting**: In the BIOS settings, PSS support can usually be enabled or disabled. When enabled, it allows the operating system to utilize these power-saving states. 4. **Compatibility**: PSS support is typically found in systems that use CPUs designed with power-saving features, such as Intel's SpeedStep or AMD's Cool'n'Quiet technologies. 5. **Impact on Performance**: While PSS support is beneficial for reducing power consumption, there can be slight impacts on performance when the CPU is transitioning between states. When configuring BIOS settings related to PSS support, it's usually best to leave it enabled for regular use, especially in systems where power efficiency is a priority.
