Advanced Chipset Features Field AMD Cool 'n' Quiet AMD-V Memory Hole Remapping Primary Video UMA Frame Buffer Size Description Select whether to enable the AMD Cool 'N' Quiet Technology. This technology allows a compliant OS to dynamically adjust the system voltage and core frequency for reduced heat and noise emission. Select whether to enable the AMD-V Technology. This technology allows a single platform to run multiple operating systems in independent partitions. When enabled, some or all of the memory between the 2 GB and 4 GB limits to addresses above 4 GB. This is a workaround for the PCI hole or PCI memory hole which is a limitation of 32-bit hardware and 32-bit operating systems that causes a computer to appear to have less memory available than is physically installed. Note: This feature is useful for systems running on 64-bit OS and those 32-bit systems that support the Physical Address Extension method. When a GPU expansion board is installed, you have the option to select which graphics controller to activate. Note: When this field is set to Auto, the graphics controller priority sequence is: PCIE, Onboard, then PCI. When a GPU expansion board is installed, you can select how the system video memory (frame buffer) is allotted.
