CPU
Supports AMD® Socket 462 series CPU with 200MHz and 266MHz EV6 Bus designed for Socket 462 technology.
Athlon: 600MHz~1.4GHz
Duron: 600MHz~1.2GHz
AthlonXP: 1500+(1.3GHz)~2000+(1.667GHz)
Chipset
The VIA Apollo KT333 consists of the KT333 V-Link DDR Host system controller and the VT8233A 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 VT8233A 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 VT8233A integrated Client V-Link controller with 200/266MB/s bandwidth between
Host/Client V-Link interface, provides a V-Link-PCI and V-Link-LPC controller. Of three PCI slots provided, MK77-333 supports
all three master PCI slots with arbitration and decoding for all integrated functions and LPC bus.
Ultra DMA 66/100/133 Bus Master IDE
Comes with an on-board PCI Bus Master IDE controller with two connectors that supports four IDE devices in two channels,
supports Ultra DMA 66/100/133, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 4, and supports Enhanced IDE devices.

Expansion Slots
Including three 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 MK77-333 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 1056MB/s. As MK77-333 includes one AGP expansion slot for a bus mastering AGP
graphic card, For AD and SBA signaling, MK77-333 can support 133MHz 2X/4X mode.
Memory
With VIA Apollo KT333 chipset, the MK77-333 can support Double-Data-Rate (DDR) SDRAM. The DDR SDRAM interface allows
zero wait state bursting between the SDRAM and the data buffers at 200/266/333MHz. The four banks of DDR SDRAM can be
composed of an arbitrary mixture of 64, 128, 256, 512MB or 1GB DDR SDRAM and maximum up to 2GB. The MK77-333 allows
DDR SDRAM to run at either synchronous or pseudo-synchronous mode with the host CPU bus frequency (200/266/333MHz).
On-board AC97 Sound
MK77-333 uses the AC97 CODEC Realtek ALC201A chip. This on-board audio includes a complete audio recording and
playback system.
LAN Port
On the strength of RealTek RTL8100BL LAN controller on board, which is a highly-integrated Platform LAN Connect device, it
provides 10/100 Mbps Ethernet for office and home use.

Four USB Connectors (1.1)
Provides two ports, four USB connectors for USB interface devices, such as mouse, keyboard, modem, scanner, etc.
1MHz Stepping Frequency Adjustment
Provides “1MHz Stepping Frequency Adjustment” function in the BIOS. This magic function allows you adjust CPU FSB
frequency from 100~166 by 1MHz stepping, and lets your system can get maximum performance.
Watch Dog Timer
Includes AOpen “Watch Dog Timer” function that can auto-reset system in 4.8 seconds when you fail to system overclocking.
Power Management/Plug and Play
The MK77-333 supports the power management function that confirms to the power-saving standards of the U.S. Environmental
Protection Agency (EPA) Energy Star program. It also offers Plug-and-Play, which helps saving users from configuration
problems, thus making the system much more user-friendly.
Hardware Monitoring Management
Supports CPU or system fans status, temperature and voltage monitoring and alert, through the on-board hardware monitor
module and Aopen Hardware Monitoring Utility.
