The AI Tweaker section of the BIOS is where all of the hardware specific settings can be adjusted. For a board that is not targeted specifically toward the gamer and overclocker, one look into the BIOS sums up the capability to adjust just about anything that impacts performance. Extreme Tweaker 2 is a process where the adjustments can be made in small steps, whereas in the past, large jumps were the only option available. Voltage adjustments can be changes in increments of .02 volts rather than the .05 commonly seen. Time to dig a little deeper into what makes the P5E3 tick.
The top of the page starts out with the AI Overclock Tuner. Manual, Auto and X.M.P. are the options. CPU ratio setting is dependent upon the CPU that is installed. The FSB strap can be left at Auto or set to one of four options to maximize performance based on the FSB speed you happen to be running.
CPU clock frequency can be adjusted from 200MHz to 800MHz. PCI-E can be tweaked from 100 to 180. Memory speed is dependent on the core clockspeed you have chosen to run. 2000 and 1600 are available if your CPU can handle to 500MHz FSB clock speed needed to get there. Command rate for the memory can be set to 1 or 2T. So far, this board likes 1T.
The number of memory timings that can be tweaked are just incredible. The settings can be set to auto or manual. Manual is, of course, for the tweakers.
AI Clock Twister and AI Transaction Booster can affect system stability as well as increase performance. Both items can be manually adjusted to help reach the maximum overclock or maximum performance of the hardware that is installed.
The bottom of the AI Tweaker page has the voltage options. The available items adjustment include the standard CPU, memory, northbridge voltage, but there is actually much more to be looked at with the P5E3. CPU voltage can be adjusted to 2.1 volts, memory can go as high as 2.78 volts, CPU PLL volts to 2.78, Northbridge to 2.21 volts. The voltage is there if you need it and want to play on the extreme side of the fence.
One more thing that can be adjusted is the Load Line Calibration. This option is effectively used to help minimize the vdroop that many boards exhibit. Auto, Normal and Performance are the available options.
After seeing how extensive the BIOS options are, I am eager to see how the board performs.
