► PCIEx16 Slot Clock
This option is used to adjust the speed of PCI Express slot. It may enhance the graphics card
speed.
► Auto Detect PCI/PCIE Clock
This option is used to auto detect PCI/PCIE slots. Setting values are: [Auto], [Disabled]. When
selected [Auto], the system will turn off clock of the empty PCI/PCIE slot to reduce EMI (Elec-
tromagnetic Interference).
► PCI Latency Timer
This item is used to set the PCI latency timer. The value is in unit of PCI cycle for PCI device
latency timer register. Setting values are 32, 64, 96, 128, 160, 192, 224, 248.
This feature controls how long each PCI device can hold the bus before another takes over.
The larger the value, the longer the PCI device can retain control of the bus. Low values for
the PCI Latency Timer will reduce the effective PCI bandwidth while higher values means
every PCI device will have to wait longer before they can get access to the bus, but when they
do get access, they can conduct their transactions for a longer time. Normally, a default value
of 64 cycles is set. Some PCI devices may not agree with longer latency times so if you start
facing problems like stuttering sound or a less responsive system, reduce the latency. Higher
values will actually reduce performance as too much time may be allocated to each PCI device
to the disadvantage of other devices on the bus.
► Allocate IRQ to PCI VGA
[YES]: Assigns interrupt request (IRQ) to PCI VGA card if the card requests IRQ.
[NO]: Does not assign interrupt request (IRQ) to PCI VGA card even if the card requests an
IRQ.
