This motherboard supports 4X AGP. AGP is a bus interface designed for high-performance 3D
graphic and supports only memory read/write operation. One motherboard can only have one AGP
slot. 2X AGP uses both rising and falling edge of the 66MHz clock, the data transfer rate is 66MHz
x 4 bytes x 2 = 528MB/s. 4X AGP is still using 66MHz AGP clock but the it has 4 data transfers
within one 66MHz clock cycle, so that the data transfer rate is 66MHz x 4 bytes x 4 = 1056MB/s.
