Agp Aperture Size (Mb) - EPOX EP-BX3 Manual

EP-BX3
Passive Release: This option allows access from the CPU to PCI bus to be
active during passive release. Otherwise, the arbiter only accepts another PCI
master access to local DRAM. The default is Enabled.
Enabled: Enabled
Disabled: Disabled
Delayed Transaction: This option allows the chipset to use its embedded 32-bit
posted write buffer to support delay transactions cycles. The default is Disabled.
Enabled: Select enabled to support PCI 2.1 specification.
Disabled: Disabled.
AGP Aperture Size: The amount of system memory that the AGP card is
allowed to share. The default is 64.
4: 4MB of systems memory accessable by the AGP card.
8: 8MB of systems memory accessable by the AGP card.
16: 16MB of systems memory accessable by the AGP card.
32: 32MB of systems memory accessable by the AGP card.
64: 64MB of systems memory accessable by the AGP card.
128: 128MB of systems memory accessable by the AGP card.
256: 256MB of systems memory accessable by the AGP card.
Auto Detect DIMM/PCI Clk: Allows you to stop DIMM/PCI Clock drive when
the DIMM site or PCI Slot are not plug. This item may help reduce EMI.
The default is Enabled.
Enabled: Provides unused DIMM/PCI to stop.
Disabled: Provides the clock generator always driving.
Spread Spectrum Modulated: Allows you to active the Spread Spectrum
Modulation function for reduce EMI. (Note: When Enabled the item that perfor-
mance will be impacted). The default is Disabled.
Enabled: Provides the Spread Spectrum function from clock generator.
Disabled: NO Spread Spectrum function.
CPU Host Clock: Allows the external clock to be modified depending upon what
FSB has been selected. Should not be used to clock processor faster than it was
designed for. (See page A-11). The default is Default.
66MHz FSB options: Default, 66.8, 68.5, 75, and 83MHz.
100MHz FSB options: Default, 100, 103, 112, and 133MHz.
