ASRock 775XFire-eSATA2 Motherboard Review :: BIOS and Overclocking

ASRock uses an American Megatrends Incorporated BIOS for its 775XFire-eSATA board with a few modifications to support the ASRock overclocking features. The BIOS is broken down into the Main, Advanced, H/W Monitor, Boot, Security and Exit submenus. The Main menu is where the System Date and System Time are located. Here you also find the BIOS Version, the Processor Type, the Processor Speed, the Cache Size, the Total Memory and what DIMM Slots are populated by memory sticks.

The Advanced Menu is where the main overclocking features of the board are present. This is split off into CPU Configuration, Chipset Configuration, ACPI Configuration, PCIPnP Configuration, Floppy Configuration, SuperIO Configuration, and USB Configuration.

BIOS Chip

The CPU Configuration is where you overclock the CPU. The board has no multiplier control, meaning overclocking is done strictly through the FSB of the CPU. The range of FSB frequencies is from 100 MHz to 300 MHz in 1 MHz increments. In practice I was unable to overclock the 3.8 GHz Pentium 670 much beyond the default setting, but the CPU is highly clocked as it is. Memory timings can be set in the Chipset Settings menu. DDR2 memory can be set here for either 400MHz or 533 MHz. Memory voltages can be set from High, Middle, and Low, without specification as to the exact voltage. VDDQ can be set from High, Low Auto, and VTT settings can be set from High or Low.
