BIOS: MSI has chosen to use a bios from American Mega trends that are very recognizable because of the blue colour. The bios on the MSI motherboard has been split up into the usual categories, like Standard CMOS, and Advanced BIOS features.
In the Hardware monitor section, it's possible to keep an eye on the RPM speeds of the fans you've got installed on the motherboard. At my present OC of 2730 MHz we get a temperature of about 35-38 degrees with stock cooling. This might not be accurate though because the bios often use its own temperature probe and not the CPU's own.
Moving on to the Cell menu, it contains all the options for overclocking the internal parts of the motherboards. You're presented with some standard OC options like D.O.T.3 1- 3 and AutoExpress. D.O.T.3 provides the opportunity of overclocking the PCI-E speed in 3 steps. If you've set all 3 to ON, it will be overclocked according to the chosen in D.O.T.3-1 when the CPU load is 20 %, and D.O.T.3-2 when CPU load is 50% etc.
Unfortunately the AutoExpress feature isn't documented in the electronic or hardcopy of the manual. Something that isn't unusual.
You still have the "regular" OC options like regulating the bus speed from 200 MHz to 600 MHz. HT ratio can be changed from x1 = 200Mhz to x13 = 2600Mhz, which probably isn't something you should hope for. If you own a Black Edition processor without multiplier lock, you will be able to change the steps in half-steps. I haven't tried it myself, and I recommend checking out MSI's website for CPU compatibility before trying.
Processor voltage can be changed from 1.277v to 1.537v, but this depends on the CPU you use, and it is changed in intervals of 0.037v. Memory voltage can be changed from 1.8 to 3.10 in intervals of 0.2v. The Northbridge can be changed in intervals of 0.025v from 1.125 to 1.525v. Finally the Hypertransport voltage is changed in intervals of 0.025 from 1.175 to 1.525. This should provide rich opportunities for frying you RAM etc.
