ECS X48T-A Black Edition Motherboard Review :: BIOS and Overclocking
ECS uses a slightly modified version of the American Megatrends AMIBIOS.ECS has the standard AMIBIOS in most respects with Standard CMOS Setup, Advanced Setup, Advanced Chipset Setup, Integrated Peripherals, Power Management Setup, PCI/PnP Setup, PC Health Status and Motherboard Intelligent BIOS as submenus.  AMIBIOS chip Standard CMOS Setup is where the Date, Time, and drives are detected. SATA1-6, Esata, PATA Master, Slave and IDE BusMaster are all detected and enabled here. Advanced Setup is where the TM Status is detected, CPUID MaxVal, C1E Halt, Intel XD Bit, Virtualization, EIST, Quick POST, and Boot Device Priority is set. Here is also where the HDD boot priority is set. Advanced Chipset Setup is where the Memory Remap and HPET features are enabled. Integrated Peripherals is where you set the SATA Configuration, enable Onboard Audio, Intel Gigabit LAN, GLAN Boot ROM, Realtek GLAN, Realtek GLAN Boot ROM, Onboard IR, USB, Legacy USB and Onchip SATA2 Controller. Setting the HDDs to RAID allows you to set the RAID mode from the menu and do RAID 0, 1, 5, 10. The MIB or Motherboard Intelligent BIOS is where the overclocking of the motherboard and tweaking of the motherboard is done. Ratio CMOS setting is the multiplier of the CPU. To enable overclocking you need to set CPU Overclocking Function to enable it. This allows you to change the FSB of the Processor, PCIE, memory voltage and processor voltage. It’s pretty straightforward but there’s no automatic overclocking function as on some motherboards. I was able to overclock the 3.2GHz QX9770 to 3.52GHz using the MIB. One issue that might hinder some people is the lack of asynchronous memory timings. While the memory runs fine at default CPU frequencies, setting the CPU FSB too high will cause problems with stability due to the memory timings not being separate from the CPU timings. One other issue with the BIOS is one of the voltage steps being 0.05V when they really should be finer for the enthusiast. PCIe frequency range: 90-150MHz Contents:
