[. . . ] The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side band addressing. When the 2x-data rate is used, the port can transmit data at 533MB/sec (66. 6*2*4). The read-queue can be used to pipeline reads ­ removing the effects of the reads-latency. Side band addressing can be used to transmit the data address on a separate line in order to speed up the transaction. 1-6 6BXA 2. · CPU · SPEED SPECIFICATION - Pentium® II / Celeron processor 233 ­ 633 MHz.

M 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. Whether your system can run under 75, 83, 112 or 133MHz properly will depend on your hardware configurations: CPU, SDRAM, Cards, etc. 3. 6. CMOS RTC & ISA CFG CMOS SRAM The mainboard contains RTC & CMOS SRAM on board. They have a power supply from external battery to keep the DATA inviolate & effective. [. . . ]
