Thank you for choosing AOpen AX34-U motherboard. The AX34-U is Intel®Socket 370 motherboard (M/B) based on the
Micro-ATX form factor featuring the VIA Apollo Pro 133T chipset. As high performance chipset built in the M/B, the AX34-U
motherboard can support CPU for Intel®Socket 370 series Pentium®III (Both Coppermine & Tualatin are supported) &
Celeron™ processor and 66/100/133MHz Front Side Bus (FSB) clock. 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 1056MB/sec. According to different
customer’s requirements, 32, 64, 128, 256 and 512MB SDRAM DIMM modules can be applied to the motherboard and the
maximum memory size can be up to 1.5 GB. 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 Audio/Modem Riser (AMR) card
option that allows audio, modem on a single baseboard design. Besides, the AX34-U motherboard has an AD 1885 AC97
CODEC chipset onboard for provides high performance and magic surround stereo
sound to let people enjoy working with it. Now, enjoy all features from AOpen
AX34-U motherboard.
