The AX4BS Pro / AX4BS-V provides an AGP 4x slot. The AGP 4x is a bus interface targeted for high-performance 3D
graphic. Recently, there are more memory modules on the AGP card. Hence, the AGP card needs more power to drive these
chips. 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 4x mode, 66MHz x 4bytes x 4 = 1056MB/s.
Warning: This motherboard supports
1.5V 4x AGP only; please DO NOT
Insert 3.3V AGP cards to prevent your
motherboard from serious damage.
