The Cell Menu section of the BIOS is where all of the performance adjustments can be made. The voltages for the CPU, System Memory and many of the motherboard components can be adjusted as well as the memory sub timings and much more.
The first section of the Cell Menu includes the CPU related options. D.O.T. (Dynamic Overclocking Technology) can be enabled or disabled. When enabled, the D.O.T. feature can be used from within the Windows environment with the Dual Core Center utility. EIST is one of the power saving features that Intel now uses with its processors. Disabling it is recommended when overclocking. Adjusting the CPU frequency will result in the reported frequency increasing based on the clock multiplier used. In this case the clock multiplier of the CPU is eight, with a core clock speed of 333MHz that results in a processor speed of 2.66GHz. 800MHz is the maximum adjustable speed. With 600+ FSB being reached with some Wolfdale processors, this level is not as unrealistic as was once thought.
The advanced DRAM Settings are accessed by entering this menu. There are several sub menus that can be accessed under this tab. Memory Z is used to view the SPD programming in detail. Once into the menu the additional memory sub timings can be viewed and adjusted. These adjustments can be made down to the single DIMM level.
The FSB DRAM ration can be left on auto so the BIOS can choose the best possible option for the occasion. Other options are available if you are adventurous enough to push your system memory to its limits. Once adjusted, the result can be viewed in the window below the option window.
Clockgen tuner allows for additional low level voltage and skew adjustments. This can help with reaching or stabilizing an overclock. Adjust PCI frequency has three adjustments, Auto, 37.5 MHz and 42MHz.
The voltage options that MSI has given the enthusiast are pretty substantial. CPU voltage to 1.9 volts, DRAM volts to 2.77 volts, MCH volts to 2.62v, FSB volts to 2.47v. The GTL reference voltages can be adjusted up or down to help stabilize your overclock or enable you to push even further.
