Athlon: 600MHz~1.4GHz
Duron: 600MHz~1.2GHz
AthlonXP: 1500+(1.33GHz)~2800+(2.25GHz)
Chipset
The VIA Apollo KT400 consists of the KT400 V-Link DDR Host system controller and the VT8235 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 VT8235 V-Link Client controller is a highly integrated PCI/LPC
controller. Its internal bus structure is based on 66MHz PCI bus that provides 4x bandwidth compare to previous generation
PCI/ISA bridge chips. The VT8235 integrated Client V-Link controller with 266/533MB/s bandwidth between Host/Client V-Link
interface, providing a V-Link-PCI and V-Link-LPC controller.
Ultra DMA 66/100/133 Bus Master IDE
Comes with an on-board PCI Bus Master IDE controller with three connectors that supports six IDE devices in three channels,
supports
Ultra DMA
66/100/133, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 4, and supports Enhanced IDE devices.

provides 10/100 Mbps Ethernet for office and home use.
Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 8X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR)
card. The
AGP video cards support data transfer rate up to 2.1GB/s. As AK77-8X Max includes one AGP expansion slot for a bus
mastering AGP graphic card, For AD and SBA signaling, AK77-8X Max can support 133MHz 2X/4X/8X mode. Of six PCI slots
provided, AK77-8X Max supports five master PCI slots for arbitration and decoding functions and one slave PCI slot.
Accelerated Graphics Port (AGP)
slot provided from AK77-8X Max can support CNR interface for a Modem/Audio
specification provides a new level of video display sophistication and speed. The
Memory
With VIA Apollo KT400 chipset, the AK77-8X Max can support Double-Data-Rate (DDR) RAM. The DDR RAM interface allows
zero wait state bursting between the RAM and the data buffers at 333/266/200 MHz. The six banks of DDR RAM can be
composed of an arbitrary mixture of 64, 128, 256, 512MB x N DDR RAM and maximum up to 3GB. The AK77-8X Max allows
DDR RAM to run at either synchronous or pseudo-synchronous mode with the host CPU bus frequency (333/266/200MHz).

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards,
and other components. Always observe the following precautions before you install a system
component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout
any procedures requiring ESD protection.

When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Manufacturer Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many
amazing and powerful features, in some situations, these powerful features are not used to every user. Hence, we changed
some key features as “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade
Optional” components, and again you can visit AOpen official web site: http://english.aopen.com.tw/

This motherboard supports AMD® Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into
CPU socket (with CPU Overheat Protection function implemented, the system will be automatically power off when the
temperature of CPU reached 97 degree, but works on AthlonXP CPU only).
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the
CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into
the socket.

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the annoying problem of high CPU
operation temperature at the same time. In order to prevent accidental failure of CPU fan, which could cause the burning down
of the AthlonXP CPU, we, AOpen, have meticulously developed a new technology, named, O.H.P. (Overheat Protection)
Technology to protect them. Thanks to the intelligent monitoring design of AOpen O.H.P. technology, user can now finally set
their mind at ease even when fan failed to work without fearing the possible damage of CPU.
Under the circumstances that CPU fan is running properly, AthlonXP temperature should be way below the highest temperature
limit of 97℃. However, if CPU fan accidentally becomes
malfunction or improperly installed, the CPU temperature
would rocket abruptly, and you may find your system
hang up or crying over the smoking CPU if you haven’t
installed AOpen O.H.P. previously. With AOpen O.H.P.
technology applied, the specific thermal detection pins
AthlonXP CPU would sense voltage difference when
processor is overheated with fan failed, and the overheat
protection system would immediately send out a signal to
abort your system by cutting CPU electricity before any
damage is done. Unlike other manufacturers who use
BIOS or software to control the power supply of CPU,
AOpen O.H.P. Technology is purely hardware-controlled
the minute after system boot-up, and occupies no system
resource. We are pleasant to phase in this practical
function on all AOpen AMD series motherboards to
protect customer’s valuable hardware and personal data.

This motherboard provides keyboard / mouse wake-up function. You can use JP28 to enable or disable this function, which
could resume your system from suspend mode with keyboard or mouse installed. The factory default setting is set to
“Disable”(1-2), and you may enable this function by setting the jumper to 2-3.

This function is dedicated to overclockers. The CPU core voltage of this motherboard is adjustable 1.1V to 1.85V by 0.05V
stepping. But this motherboard can also automatically detect CPU VID signal and generates proper CPU core voltage.

Warning: Higher CPU core voltage may be
able to increase CPU speed for overclocking,
but you may damage the CPU or reduce the
CPU lifecycle.

Warning: Supposed you have had adjusted CPU

new CPU. Please use <Home> key or Clear CMOS
to restore the default setting when changing a new
CPU, because the system will still implement the
previous CPU setting on the new one.
Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the
default setting or you can wait the AOpen “Watch Dog

will auto-detect hardware again.
