CPU
Supports AMD
®
Socket 462 Athlon™ & Duron™ 600MHz~1GHz+ with 266MHz EV6 Bus designed for Socket 462 technology.
Chipset
The VIA Apollo KT266 consists of the VT8366 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 five PCI slots provided, AK77 Pro supports all five master PCI slots with
arbitration and decoding for all integrated functions and LPC bus; while AK77 Plus supports four master PCI slots for arbitration
and decoding functions also and one slave PCI slot.
Expansion Slots
Including five 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 AK77 Plus / AK77 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 AK77 Plus / AK77 Pro includes one AGP expansion slot
for a bus mastering AGP graphic card, For AD and SBA signaling, AK77 Plus / AK77 Pro can support 133MHz 2X/4X mode.
