  • Page 8 Introduction The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI bridge device that supports an AGP port. The main purpose of the AGP port is to provide fast access to system memory. The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32- bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side band addressing.

    Hardware Installation SW2: CLK RATIO X3.5 X4.5 X5.5 X6.5 The CPU is a sensitive electric component and it can be easily damaged by static electricity, so users must keep it away from metal surface when the CPU is installed onto mainboard. Note: We don’t recommend you to setup your system speed to 75, 83, 112 or 133MHz because these frequencies are not the standard specifications for CPU, Chipset and most of the peripherals.
