Now that I have shown the more mundane options in the BIOS, it's time to look at where the enthusiast spends most of the time on a board like this. The Advanced tab contains all of the settings the enthusiast needs to get the most from the board.
The Jumperfree section is where the processor and memory specific settings are made. The default settings leave just about all of the options set to auto. The good thing is that the base settings are pretty good right out of the box. There are several options available to the user here. You can use auto to load optimal settings. Manual for manual settings, Standard to load the non-optimized options, or the N.O.S. (Non- Delay System overclocking) option to allow the system to make changes based on system load.
I have chosen to show the options available when set to manual mode. Why you ask? This will allow me to show the options the enthusiast wants to know about. This is OverclockerClub.com, you know. Setting CPU ratio control to enabled allows the clock multiplier to be adjusted down or up based on the limitations of the processor installed.
The northbidge strap can be adjusted from 200 to 333 FSB. Making adjustments here can help or hinder your overclock. The FSB frequency is adjustable from 200 to 800 FSB. Incredible if it can be achieved.
If you are looking for the last bit of bandwidth and clock speed, you can look at adjusting the PCI-E frequency. Adjustment are from 100 to 150. The DRAM frequency is tied into both the processor FSB and northbridge strap settings.
DRAM command rate can be set to Auto, 1 tor 2T. Setting DRAM timing control to manual gives the user full control of the memory's primary and secondary timings.
Moving down further, the voltage options are available. Processor voltage can be adjusted from 1.100 to 1.70. Not as high as some other enthusiast boards out there, but still enough to get the job done for most people. The voltage reference can be adjusted within a narrow range to keep the enthusiast from going too far off base. Finally, someone has managed to have an option available to help eliminate the droop in CPU voltage that most boards are plagued with. Options are auto, enabled and disabled.
The rest of the voltage options have varying effects that can only be tested on each individual system. The voltages are there to get the most from your hardware. Memory voltage has a maximum of 2.5 vdimm. This is lower than some other company's offerings, but will keep you from throwing 3.0 volts to the memory.
