The AK76F-400N provides an
AGP
2X/4X/8X slot. The AGP 8X is a bus interface targeted for high-performance 3D graphics. AGP supports
only memory read/write operation and single-master single-slave one-to-one only. AGP uses both rising and falling edge of the 66MHz
clock, for 2X AGP, the data transfer rate is 66MHz x 4bytes x 2 = 528MB/s. AGP is now moving to AGP 8x mode, 66MHz x 4bytes x 8 =
2112MB/s. Please be noticed that the AGP expansion slot supports 1.5V AGP cards only. The system will be protected and not able to boot
up if a 3.3V AGP card is installed. The AGP slot voltage can be adjusted to 1.50V, 1.53V, 1.56V and 1.60V.
