within the BIOS.
[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]. (GfX0-PCI Express
x16 graphics card; IGfX-onboard VGA; PCI-PCI graphics card.)
► Surround View
SurroundView is the ATI technology that provides multi-graphics controller display capabil-
ity for both the ATI PCIe-based graphics card and the ATI integrated graphics processor
(IGP). Enabling SurroundView does not impact display modes (resolution and color depth) or
performance. The display mode of each output is controlled independently by the graphics
controller connected to it.
1. When using a non-ATI PCI Express (PCIe) graphics card, SurroundView is not supported.
The integrated graphics processor (IGP) is automatically disabled, and the system memory
allocated to the IGP is freed for other use.
2. When installing an ATI PCIe graphics card, SurroundView is disabled by default. Enabling
SurroundView in the BIOS enables the integrated UMA graphics controller, which in turn
makes available up to two additional graphics outputs. When enabling the integrated UMA
graphics controller, system memory will be reallocated.
► 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.
