21-1 Main Specifications PCB board size and form factor: 24.5 x 30.5cm, ATX type. PCB layer: 4 layers Supported CPUsCan support the latest 200/ 266MB FSB Socket-462 AMD Athlon XP (up to 2000+)/Athlon (up to 1.4GHz) or Duron (up to 1.2GHz) CPUs or higher speed. Chipset NorthbridgeThe VIATM KT266A system controller is a 200/ 266MHz System Bus. The DRAMcontroller supports DDR200/ DDR266 Double Data Rated (DDR) SDRAM; it complieswith AGP 2.0 specifications for 4X, 2X AGP modes and PCI 2.2 bus interface with supportfor 6 PCI masters. It was designed especially to deliver enhance AMD® Athlon XP/ Athlonor Duron processor system performance. Chipset SouthbridgeThe VT8233 PCI Super-I/O Integrated Peripheral Controller (PSIPC) support Ultra/DMA/100, which allows burst mode data transfer rates of up to 100MB/ sec; AC97 audio (usingthe on-board VIA VT1611A Audio Cadec); USB controller with root hub and four functionports. MemoryThis motherboard comes equipped with three Double Data Rate (DDR) Memory Modulesockets to support DDR 200MHz/ 266MHz-compliant (128, 256MB, or 512MB) DDRModules up to 3GB. AGP (Accelerated Graphics Port)This motherboard comes with an AGP slot with support for AGP cards for highperformance. The AGP 66MHz 4X mode is supported as well, further increasing systemperformance. PCI Expansion SlotsWith six 32-bit PCI (Rev. 2.2) expansion slots, which can support Bus Master PCI cards,such as LAN or Video-grabber cards (PCI supports up to 133MB/s maximum throughput),this motherboard is ready for the most demanding applications.
