ECS A780GM-A makes use of a pretty standard AMI BIOS menu.
The main BIOS screen.
Standard CMOS Setup, which allows you to adjust the Date & Time and access drive information.
The Advanced Setup section lets you change system settings such as the Hyper Threading Frequency, boot device priorities and CPU throttling. The Hyper Threading Frequency can be adjusted from 200MHz to 1.8GHz or just left at the default AUTO setting.
The Advanced Chipset Setup provides for even more system alteration. You can alter Memory Frequency from 200MHz to 533MHz. You can change shared RAM size, which is the amount of system memory reserved for IGP (Integrated Graphics Processor). The amount of system RAM you can reserved ranges from 32MB to 1GB. This is also the menu in which you can manually set system RAM timings if you need to do so.
Next up is the Integrated Peripherals section. This is where settings such as the on-board IDE/SATA controllers, Audio, LAN, and USB are configured.
The PC Health Status section, which displays system temperatures and fan speeds. System shutdown temperature values can be set here as well.
The only option you can configure in the PCI/PnP Setup section is the initial display at boot.
Moving over to the Frequency/Voltage control menu in the BIOS we find more settings that can be configured such as CPU voltage, DIMM voltage and CPU Over-clocking function.
Now this is the strange thing about the board, ECS decided to list the voltage ranges in millivolts (mV). Also, the range goes from 0-63(+252mV) for the CPU, but makes no mention of what the starting reference voltage is. This places a lot of guesswork into the voltage adjustments by users seeking to overlcock the system.
Same story for the DIMM voltage.
When the CPU Over-clocking option is enabled, the board allows for a selectable range of up to 500.
