Connecting AGP 8X Expansion Slot
This motherboard provides 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.
Warning: It is
strongly recommended
not install a 3.3V AGP
card, which is not
supported by SIS 661FX
chipsets on this
motherboard.
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.
