Check the BIOS settings for the PEG-ASPM configuration on the ASUS Q87M-E.
The settings you described control how the system handles PCIe devices in ASUS Q87M-E.
- **Disabled**: The PEG feature is turned off completely.
- **ASPM Loops**: Activates or deactivates ASPM during boot, allowing it to manage PCIe devices.
- **ASPM LOs**: Enables low-power mode for PCIe devices, reducing power consumption.
- **ASPM L1**: Engages full ASPM functionality, offering maximum performance and power efficiency.
Choosing these options affects device management, power usage, and boot behavior.
Active-state power management is a system designed to reduce power consumption for PCI Express devices when they are not actively transmitting data. It mainly works by managing the power of the serial link, turning it off when no traffic is present. The configuration options include L0, which keeps all transactions active with minimal latency and energy use; L0s, offering a slightly slower but more energy-efficient standby mode; and L1, providing higher latency for even lower power consumption (optional). When both L0s and L1 are enabled, the system balances responsiveness with savings.
