3 within the BIOS. [UMA+SIDEPORT]-The SidePort is a 32-bit DDR memory interface that the integrated graphics can use either instead of or alongside the Athlon 64's memory controller. In this mode, the integrated graphics cores will request data from both the UMA space and SidePort memory. ► UMA Frame Buffer Size Allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance. This is a memory allocation method addition to the Unified Memory Architecture (UMA) concept, wherein a static amount of page-locked graphics memory is allocated during driver initialization. This fixed amount of memory will provide the user with a guaranteed graphics memory at all times, and will no longer be available to the OS. ► SIDEPORT Clock Speed This item will appear only when "Internal Graphics Mode" is set to [UMA+SIDEPORT], it used to adjust sideport clock speed. ► UMA-SP Interleave Mode This item will appear only when "Internal Graphics Mode" is set to [UMA+SIDEPORT], it used to set the UMA and sideport interleave mode. Setting values are: [Auto], [Coarse], [Fine]. The interleave Ratio/Size selected based on system configuration. ► Primary Video Controller This item allows you to select the priority of boot sequence from different display devices. Setting values are: [GFX0-IGFX-PCI], [PCI-GFX0-IGFX], [IGFX-GFX0-PCI]. (GFX0-PCI Express x16 graphics card; IGFX-onboard VGA; PCI-PCI graphics card.) ► AMD 780 HD Audio This item is used to set whether the HD Audio controller is enabled through the HDMI port on the rear panel. 36

[UMA+SIDEPORT]
-The SidePort is a 32-bit DDR memory interface that the integrated graph-
ics can use either instead of or alongside the Athlon 64’s memory controller. In this mode, the
integrated graphics cores will request data from both the UMA space and SidePort memory.
► UMA Frame Buffer Size
Allocates system memory for use as video memory to ensure the most efficient use of
available resources for maximum 2D/3D graphics performance.
This is a memory allocation method addition to the Unified Memory Architecture (UMA)
concept, wherein a static amount of page-locked graphics memory is allocated during driver
initialization. This fixed amount of memory will provide the user with a guaranteed graphics
memory at all times, and will no longer be available to the OS.
► SIDEPORT Clock Speed
This item will appear only when "Internal Graphics Mode" is set to [UMA+SIDEPORT], it used
to adjust sideport clock speed.
► UMA-SP Interleave Mode
This item will appear only when "Internal Graphics Mode" is set to [UMA+SIDEPORT], it used
to set the UMA and sideport interleave mode. Setting values are: [Auto], [Coarse], [Fine]. The
interleave Ratio/Size selected based on system configuration.
► Primary Video Controller
This item allows you to select the priority of boot sequence from different display devices. Set-
ting values are: [GFX0-IGFX-PCI], [PCI-GFX0-IGFX], [IGFX-GFX0-PCI]. (
