The parameters are of course all at their defaults when you start the mainboard up for the first time, and you can try the Auto Overclock System (AOS).

Choosing from three variants, you can overclock the system by 5-10% with the V6 Tech Engine, by 15-25% with the V8 Tech Engine, and by 25-30% with the V12 Tech Engine option. AOS works indeed, but is not very interesting for overclockers. For example, when I chose the V12 Tech Engine option, my Intel Core 2 Duo E6300 was overclocked from the default 266MHz FSB to 285MHz FSB only.
You get much wider opportunities if you specify the parameters manually (Manual Overclock System – MOS).

Here’s a list of adjustable parameters:
- CPU Voltage: can be increased by 0.787V above the default value stepping 0.012V
- FSB Termination Voltage: 1.2-1.5V stepping 0.1V
- (G)MCH Voltage: 1.25-1.55V stepping 0.1V
- Memory Voltage: 1.9-2.6V stepping 0.1V
- System Memory Frequency: 533, 667, 800MHz
The DRAM Configuration subsection is where you control the memory timings:

It’s handy that you can adjust necessary timings independently of the others. You can change just a few of them, leaving the rest at their defaults.
The last item in this section is called Integrated Memory Test. When you enable it, MemTest86+ v.1.65 is run after the POST to check memory for errors before booting the OS.
So, I have no complaints about the options offered by the Overclock Navigator Engine. Everything is easy to work with. The next section – CMOS Reload Program – is of some interest, too.

This section allows to save current BIOS settings and load them again later as necessary. This feature is available on mainboards from Abit, ASUS and DFI, but Biostar surpassed them all – the mainboard allows saving as many as 50 different profiles with settings!

I checked this feature out and it did work, but my patience and imagination were not enough for all the 50 entries. These entries do not vanish if you clear the CMOS, but they do when you update the BIOS.
The last BIOS item is called Integrated Flashing Program. This sound like a good option, but the program works only with floppy diskettes and cannot save the previous version of the BIOS. Its usefulness is thus rather limited.
