Native, True Quad-Core Processor – Improve overall performance
AMD Phenom™ FX Processors are the True Quad-Core Processors which allow cores to communicate on the same piece of silicon using Direct Connect Architecture with caches and core performance enhancements

Hyper Transport3.0 Technology
With Hyper Transport3.0 Technology, they system supports Socket AM2/AM2+ 940 Processor up to 5200MT/s

Integrated DDR2 Memory Controller –Support Dual DDR2 1066
Users are able to get a faster and better PC experience due to the Integrated Dual Channel DDR2 Controller with up to DDR2 1066 support which allows dramatic application performance improvements with greater system throughput and lower latency

For high-end gaming and Xtreme visual performance the abit AX78 is equipped with two PCI Express 2.0 x 16 slots (1x16, 1x4 bandwidth) supporting ATI dual graphics.

Clear the CMOS memory directly from the back panel, using abit's innovative new EZ switch. It is easy and convenient to go back to safe grounds if you are pushing your hardware to the extreme and experiment with risky settings.

abit's Silent OTES™ heatpipe technology dissipates heat from the chipset and conducts it to a highly effective heatsink. This fanless solution keeps your motherboard cool and quiet.

4 Phase PWM-better power switch efficiency, and power supply
4-Phase-PWMs are composed of high quality Japanese-made capacitors. Each phase is composed of one high-side MOS and two low-side MOS. This design brings the system with better power switch efficiency.  Also, with 4-phase-PWMs, the system is providing better power supply and increased stability.

PWM Heatsink-less heat, increased performance
With a dedicated heatsink on the PWM area, generated heat is efficiently dissipated, providing end-users with a more consistent and stable environment.

1 Phase PWM support DDR2 Memory
1 phase PWM which is also composed of high quality Japanese-made capacitors, delivering enhanced voltage stability to DDR2 memory.
