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. Memory Configuration CMOS Setup Utility - Copyright (C) 1985-2006, American Megatrends, Inc.

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.
Memory Configuration
► Bank Interleaving
Interleaving allows banks of SDRAM to alternate their refresh and access cycles. One
bank will undergo its refresh cycle while another is being accessed. This improves memory
performance by masking the refresh cycles of each memory bank.
However, bank interleaving only works if the addresses requested consecutively are not in the
same bank.
► Channel Interleaving
Dual channel (Interleaved) mode offers the highest throughput for real world applications. Dual
channel mode is enabled when the installed memory capacities of both DIMM channels are
equal. If different speed DIMMs are used between channels, the slowest memory timing will be
used.
► Enable Clock to All DIMMs
This setting is to control EMI.
When disabled, the system will turn off clock on the empty DIMM slots and to reduce EMI
(Electro-Magnetic Interference).
► MemClk Tristate C3/ATLVID
Enables the DDR memory clocks to be tristated when alternate VID mode is enabled.
► Memory Hole Remapping
This item is used to enable/disable memory remapping around memory hole.
PCI doesn't actually care much which addresses are used, but by convention the PC platform
