BIOS Features
Abit’s BIOS have long been mimicked and imitated, and always they seem able to come up with new features and options for gamers and enthusiasts alike.
This is the initial BIOS screen you get when entering the OC Guru section of the BIOS. You can see there are all types of options for modifying properties of the processor and various voltages.
Here we see that the external clock (FSB) can be modified anywhere from 100 MHz to 400 Mhz for overclocking purposes.
Processor core voltages can go as high as 1.925v…
FSB voltages can be modified as well here, up to 1.8v.
DDR2 voltages can be set up to 2.55v, well over the default 1.8v that DDR2 uses!
And again, the DDR2 bus voltage can be bumped all the way up to 1.8v like the FSB bus.
The north bridge voltage is able to be increased to 2.10v.
Finally, a separate north bridge voltage, called the NB 2.5v, can be modified up to 3.0v. I am not positive on the purpose of this additional voltage setting on the chipset, but I am guessing it is regarding the overclocking potential of the 925XE.
