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, SDRAM, 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. Of six PCI slots provided, AX37D Plus supports four master PCI slots with
arbitration and decoding for all integrated functions and LPC bus, and two slave PCI slots; while AX37D Pro supports five master
PCI slots with arbitration and decoding functions also and one slave PCI slot.
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 AX37D Plus / AX37D 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 AX37D Plus / AX37D Pro includes one AGP expansion
slot for a bus mastering AGP graphic card, For AD and SBA signaling, AX37D Plus / AX37D Pro can support 133MHz 2X/4X mode.
