CPU
Supports Intel
®
Socket 370 Pentium III
®
& Celeron™ 533MHz~1GHz+ with 66/100/133MHz FSB (Front Side Bus) designed for
Socket technology.
Chipset
The VIA Apollo Pro266 consists of the VT8633 V-Link DDR Host system controller and the VT8233 highly integrated V-Link Client
PCI/LPC controller. The Host system controller provides superior performance between the CPU, DRAM, AGP bus, and V-Link
interface with pipelined, burst, and concurrent operation. The VT8233 V-Link Client controller is a highly integrated PCI/LPC
controller. Its internal bus structure is based on 66MHz PCI bus that provides 2x bandwidth compare to previous generation
PCI/ISA bridge chips. The VT8233 integrated Client V-Link controller with 266MB/s bandwidth between Host/Client V-Link interface,
provides a V-Link-PCI and V-Link-LPC controller. It supports five PCI slots arbitration and decoding for all integrated functions and
LPC bus.
Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 4X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR)
slot provided from AX37 Plus/AX37 Pro can support CNR interface for a Modem/Audio
card. The Accelerated Graphics Port (AGP)
specification provides a new level of video display sophistication and speed. The AGP
video cards support data transfer rate up to 1066MB/s. As AX37 Plus/AX37 Pro includes one AGP expansion slot for a bus
mastering AGP graphic card, For AD and SBA signaling, AX37 Plus/AX37 Pro can support 133MHz 2X/4X mode.
