ECS A790GXM-AD3 Reviewd3bruts1d , ajmatson - May 10, 2009
I can never stress enough on how important the BIOS of a motherboard is. I have seen some of the best boards brought down by a very weak BIOS. I am going to take you through the BIOS of the ECS A790GXM-AD3 motherboard in sections, so that you can get a better look at what is available for you in your tweaking and overclocking adventures. When you first boot into the BIOS, you are presented with a menu screen. This main screen allows you to easily navigate your way through the BIOS without having to waste time finding what you need. If you saw the review of the ECS A790GXM-A then this BIOS might look familiar to you. That is because it is the same exact BIOS (American Megatrends version 2.62) for both boards.
The Standard CMOS section is where you can change the time and drive options for hard drives and floppy drives.
Advanced Chipset & Integrated Peripherals:
In the Advanced Chipset section there are options to enable CrossFire mode and change what display device is started, such as the onboard video or a PCI Express card. In the Integrated Peripherals section there are options for SATA mode for RAID or hot swap ability, LAN devices being enabled or not and the IRQ for the serial port.
Power Management & PCI/PnP Setup:
In these sections you can change the power states of the motherboard and how a motherboard reacts to being woken up by devices. You can also set the system to allocate an IRQ to the onboard video if needed.
PC Health Status:
This section of the BIOS allows you to monitor the health of the system such as the temperatures, speeds, and voltages of the devices on the board. You can also set Smart Fan functions which adjust the fan speeds based on the temperatures of the board and CPU.
