Once you get past the basic settings in the BIOS, it's time to dig a little deeper into the Extreme Tweaker section. Unlocking the potential of this board is accomplished under this tab. The Extreme Tweaker section contains all of the settings that the PC enthusiast needs to maximize the performance of the board.
The default settings of Auto will allow the installed hardware to perform at the expected levels you would get with no tweaking. 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. CPU ratio control is used to adjust the clock multiplier up or down based on the limits of the installed CPU.
FSB strap setting can help or hinder performance and ultimate clock speeds when overclocking. DRAM Frequency is adjustable in a narrow range based on the clock speed of the installed processor and the clock speed the processor is manually se to run at. DRAM Command Rate allows for Auto 1t or 2t. 1t of course offers the best performance.
DRAM timing control can be set to Auto or Manual. The manual setting allows the memory timings to be tweaked for the best system performance.
Manual adjustment of the CPU frontside bus frequency is adjustable from 200 to 800 FSB. The room is there to play if your hardware is capable. Additional bandwidth on the PCI-E bus can be gained by adjustments to the PCI-E frequency.
The voltage options on the Blitz are substantial enough that voltage tweaking should be the least of your worries. CPU voltage up to 1.90 volts and memory voltage up to 3.04 volts! That's double the DDR3 specification! There is also the ability to manually offset voltage to the memory, and t he loadline calibration feature allows the voltage droop on the CPU to be minimized.
The rest of the voltage options have varying effects on the maximum overclock and system stability. Each voltage will need to be tried on your particular combination to get the most from your hardware.
