EPoX includes a very interesting BIOS with their board. The first screen at boot is normally the BIOS bootup screen. EPoX decided that the following information would be useful as well as the CPU, the drives, and the memory test: CPU temperature, the CPU fan speed, CPU Voltage, +5V voltage, System Fan Speed, System Temperature, DIMM Voltage, 5VSB Voltage, Power Fan Speed, Chipset Voltage, +3.3V, and Battery Voltage.

The BIOS itself is the standard Phoenix Award Workstation BIOS with a few modifications. The HyperTransport multiplier can be manually set from 1x-5x or to Auto. The DRAM configuration screen in the BIOS allows you to change 1T/2T Memory Timing. CAS Latency (tcl), RAS to CAS (tRCD), Min RAS#active time (tRAS), Row Precharge time (tRP) and Row precharge time (tRP). One thing EPoX includes in the software bundle is USDM (Unified System Diagnostic Manager). This application monitors Fan Speed, Temperature, and Voltages in Windows without needing to go into the BIOS.

Overclocking options on the board are situated in the Power BIOS settings section. From this location you can change the CPU frequency from 200MHz (default)-400MHz in 1MHz increments, change the PCIE clock from 100MHz-145MHz in 1MHz increments, Real Time Turbo mode with a DEC number from 0-31 and Memory Frequency with settings from 100-200MHz in 33MHz increments. If you have an unlocked FX chip, you can change the CPU multiplier from 5-25. On my 4000+, the choices were 5-12x (the default ratio). CPU voltage can be changed from the default 1.55V-1.8V in 0.05V increments. DIMM voltage can be changed from 2.5V-3.1V in 0.1V increments. Finally, chipset voltage can be changed from 1.5V to 1.8V in 0.1V increments. I was able to overclock the 4000+ we use to 2.7GHz successfully, a 15% overclock.
