Thank you for choosing AOpen AK73(A)-V / AK73-V. The AK73(A)-V / AK73-V is AMD®Socket 462 motherboard (M/B) based on
the ATX form factor featuring the VIA Apollo KT133A chipset. As high performance chipset built in the M/B, the AK73(A)-V /
AK73-V can support AMD®Socket 462 series Athlon™ & Duron™ processor and 200/266MHz (EV6) system bus. In the AGP
performance, it has one AGP slot and supports AGP 1X/2X/4X mode and pipelined spilt-transaction long burst transfer up to
1066MB/sec. According to different customer’s requirements, SDRAM and VCM (Virtual Channel Memory) can be applied to the
AK73(A)-V / AK73-V and the maximum memory size can be up to 1.5GB. The on-board IDE controller supports Ultra DMA
33/66/100 mode and the transfer rate up to 100MB/s. Further flexibility can be achieved by taking advantage of the
Communication and Network Riser (CNR) card option that allows audio and modem configuration on a single baseboard design.
Besides, the on-board AC97 CODEC chip (Optional) provides high performance
and magic surround stereo sound to let people enjoy working with AK73(A)-V /
AK73-V. Now, enjoy all features from AOpen AK73(A)-V / AK73-V.

About “Optional” and “Upgrade Optional”…
When you read this online manual and start to assemble your computer system, you may find some of functions are “Optional”,
and some are “Upgrade Optional”. This is because all of AOpen motherboards include many amazing and powerful features;
however, some of these are not frequently used on daily operation. Therefore, we define some key features as optional to meet
different requirements. Functions that can be upgraded by users, we define them as “Upgrade Optional”. The other optional
functions that may have been built on the motherboards and you cannot upgrade by yourself, we call them “Optional”. If needed,
you can contact your local distributors or resellers to purchase “Upgrade Optional” components. Also you can visit AOpen official
web site: www.aopen.com.tw <http://www.aopen.com.tw> to get detailed information.

Feature Highlight
CPU
Supports AMD® Socket 462 Athlon®& Duron®600MHz~1.4GHz with 200/266MHz EV6 system bus designed for Socket 462
technology.
Chipset
The VIA Apollo KT133/KT133A chip incorporated a VIA VT8363A north bridge is in charge of the host bus interface and memory
bus control. The memory bus control supports two and four-way interleaved of PC-100 and PC-133 SDRAM DIMM and VCM up
to 1.5GB. The north bridge provides one 32bit PCI bus running at 33MHz.
Memory
The three 168-pin DIMM system memory sockets support up to 1.5GB of PC-100/133 compliant SDRAM (Synchronous Dynamic
Random Access Memory), VCM (Virtual Channel Memory) and PC-100/PC-133 DIMMs. You can install 32, 64, 128, 256 and
512MB SDRAM DIMM module into each socket.
Expansion Slots
Including five 32-bit/33MHz PCI slots, one CNR and one AGP slot. The PCI local bus throughput can be up to 132MB/s. The
CNR (Communication and Networking Riser) slot provided from AK73(A)-V / AK73-V can support CNR interface for a
Modem/Lan/Audio card.

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
procedure requiring ESD protection.

This motherboard supports AMD Athlon & Duron Socket 462 CPU. Be careful of CPU orientation when you plug it into CPU
socket.
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.
3. Press down the CPU socket lever and finish CPU
installation.
Note: If you do not match the CP
