▶ CPU PCIe Lanes Configuration Configures the PCIe lanes from CPU for adapting multiple PCIe devices usages. ▶ PCI Latency Timer Sets latency timer for PCI interface device. ▶ Max TOLUD Sets the maximum TOLUD (Top of Low Usable DRAM) value. ▶ Above 4G memory/ Crypto Currency mining Enables this item to allow more memory address configuration space (requires 64 bit OS) with another optimized setting for better device compatibility and it might slightly affect the efficiency of PCIe-based devices. [Enabled] Allows you to utilize more than 4x GPUs. [Disabled] Disables this function. ▶ Re-Size BAR Support Enables or disables the Resize BAR (Base Address Register) support. It is only available if the system supports 64-bit PCI/ PCIe decoding. If the system supports 64-bit PCI/ PCIe decoding, please enable this item for compatible PCIe devices. ▶ Native PCIE Enable Enables or disables the PCIE native control. ▶ Native ASPM If enabled, the native ASPM will be controlled by OS. If disabled, the native ASPM will be controlled by BIOS. ▶ PCIe/PCI ASPM Settings Sets PCIe/ PCI ASPM (Active State Power Management) state for different installed devices. Press Enter to enter the sub-menu. ▶ PEG 0 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. ▶ PEG 1 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. ▶ PEG 2 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. ▶ PEG 3 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. ▶ PCI Express Root Port 1 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. ▶ PCI Express Root Port 5 ASPM Sets PCI Express ASPM (Active State Power Management) state for power saving. 14 BIOS Setup
