Connecting AGP 8X Expansion Slot
i865Gm-I / i865Gm-IL provide an AGP 8X slot. The AGP 8X is a bus interface
targeted for high-performance 3D graphic. Traditionally AGP used both rising and
falling edge of the 66MHz clock for 4X AGP, and the data transfer rate could
achieve 66MHz x 4bytes x 4 = 1056MB/s. Now AGP is moving to AGP 8X mode,
which is upgraded to 66MHz x 4bytes x 8 =2.1GB/s. The AGP slot can
automatically recognize an AGP or a Multiplexed Intel DVO Output depending on
which cards being inserted, such as AGP, or ADD (AGP Digital Display) cards. With
an ADD card implemented to this slot, Multiplexed Intel DVO output will provide
high-speed digital connection for digital displays or TV-OUT functionality.

Warning: It is strongly
recommended not adjust AGP/PCI
voltage/clock when you connect SATA
device. It is because when the
voltage/clock for AGP/PCI is adjusted,
the SATA clock cannot remain at
100MHz, and the
system will therefore
be unstable.
Warning: It is
strongly recommended
not install a 3.3V AGP
card, which is not
supported by Intel 865G
/ 865GV
chipsets on this
motherboard.
