The EPoX AF570+ uses the Phoenix Award BIOS with a few modifications for EPoX. The BIOS is split into Standard CMOS Features, Advanced BIOS, Advanced Chipset Features, Integrated Peripherals, PC Health, Power BIOS. So let's cover each setting separately.

Main BIOS screen


The Standard CMOS Features has the Time Date, IDE Master Slave, Drive A and amount of Memory. The first thing to do with the system is to set the correct time and date as different areas have different time zones. The amount of memory is a good indicator as to whether your installed memory is correctly identified or not.

Advanced BIOS


The Advanced BIOS area of the BIOS is where you can set the Removable Device Priority, the HDD Boot Priority and the CD-ROM Priority if you have multiples of each. This is also where you can set the Primary Display Adapter to either PCI Express or PCI Slot, depending on what the graphics card is installed into. The last item on the Advanced BIOS settings is the First Second and Third Boot Device.

The Advanced Chipset Features is where the HyperTransport Speed and Bus Bandwidth are set, from 1x-5x and 8bits up and down or 16 bits up and down. The major Submenu in this area is the DRAM configuration menu. Here you can set the Memory Timing, the CAS Latency, and the RAS to CAS Delay, the Row Precharge time and more. You can also set the Spread Spectrum for the CPU, PCIe, SATA and HyperTransport to enabled/disabled.

The Integrated Peripherals menu has the Chipset IDE devices, the Onboard Devices and the Legacy Devices sub menus. The Chipset IDE Devics menu has the UDMA enabler for the motherboard, the Onchip IDE controller enable/disable, and the SATA RAID enabler. The onboard devices submenu has the options for the USB, the P80 LED that shows the CPU temperature, and the High Definition Audio.

PC Health


The PC Health screen is where the important stats for the CPU temperature, Voltage and fan Speed are located. CPU, System, and Thermal Stick temperatures are measured. CPU/Power and System fans speeds are measured here as well. Finally, the Voltage of the CPU, DIMM slots and Chipset are monitored in the PC Health area of the BIOS.

The Power BIOS is where you do your overclocking. The CPU Overclock Frequency can be set from +0MHz to +250MHz in 1 MHz increments. The PCI Express clock frequency can be set from 100-145MHz in 1MHz increments. The CPU Clock Ratio can be set from x4 to x10. CPU Voltage can be set from 0.0125V to +0.5750V. Chipset Voltage range is from 1.5V-1.7V in 0.1V increments. HyperTransport Voltage ccan be set from 1.30V to 1.60V. DIMM Voltage range is from 1.2V to 1.5V. The memory clock is also set here from DDR2 400, 533, 667, 800MHz.

nTune


The board was an interesting one to overclock. By lowering the multiplier and increasing the FSB I was able to overclock the 5000+ CPU to 280MHz FSB. Using the nTune utility from NVIDIA to tune the system resulted in a overclock of only 2% for the CPU. However, the PCI Express bus clock was adjusted +14% with nTune and the 7900GT oveclocked to 564MHz for the core using nTune.
