Biostar TA770 A2+

3. The BIOS

The familiar Phoenix - Award Bios appears upon booting up the system, customized by Biostar of course. The most interesting tab here is the " Overclock Navigator Engine."

The PC Health Status settings are also very helpful, offering detailed information about the temperatures, voltages and fan speeds.

In the overclocking Navigator Engine tab, we can control all the major functions of the board. There are three pre-defined overclocking steps, (V6 Tech - 10%~15%, V8 Tech - 15%~25%, V12 Tech - 25%~30%). For our tests, we select the "Manual Overclock" setting.

The CPU voltage can be set at +0.012V reaching up to +0.787V, in predefined steps . This however isn't very practical, since in order to calculate the actual CPU voltage you should sum your current voltage selection with the base voltage setting.

Memory voltages start from 1.95V and can go up to 2.90V.

The available HT Voltage settings also start from 1.250V and reach the 1.525V

More voltage settings for NB/SB; the motherboard can set to 1.150V~ 1.400 in steps of 0.02/0.03.

Entering the DRAM tab brings us in front of tons of different settings. According to the type of memory you have installed, you can set up the DDR/FSB divider from 1:1~1:2 (only with Phenom processors).

Lastly, the FSB can be typically set from 200~600MHz.
