Now that we have a general idea of what you can accomplish in the BIOS, let's take a look at the Advanced Chipset Section again. This is where all the system tweaking will take place to overclock your computer. One thing I cannot stress enough, is take overclocking in baby steps. Never just rush in and pump the CPU and other components, or you may destroy your Windows partition, or worse, destroy your components. I encourage all to learn how to overclock, but take it slow to get it right.
The system clocks tab is where you can change the CPU Multiplier from auto to 4x - 8x (on my CPU), adjust the PCI-e bus speeds, and the speeds for the Southbridge and the Northbridge.
FSB and Memory Config:
This is where the tweaking really gets into action. Here you can have the system auto overclock your computer if you have EPP memory by telling it how far you want it to go, from 0% to 5% overclocked, and then expert. Expert allows you to manually change the CPU and Memory speeds, link them together via memory dividers, or unlink them to run them at individual speeds.
Here in the memory config you also have the ability to set the memory timings manually. This is great for either tightening or loosening the timings for better overall performance.
This section allows you to alter the CPU's thermal controls, Turn off Speedstep, and disable one or more of the cores of a multi-core CPU.
Now this is the tricky part. You want to be very careful what you pump into the components. XFX makes it easy to change the voltages you need giving you control over the CPU voltage, CPU Front Side Bus voltage, Memory voltage, Southbridge voltage, Northbridge voltage, and the voltage linking the Northbridge to the Southbridge.
NVMEM Memory Test:
This setting allows you to run a memory test on POST to verify if your memory is functioning properly. There are four settings: Off, Fast, Medium and Slow. The slower the test the more accurate it is.
Load and Save Voltage/Timing Set:
This nifty little feature allows you to save three profiles of voltages and timings for you to recall if you have to clear your CMOS or if you have different sets of RAM you use. Just set up the way you want your voltages and timings and save it to one of the three profiles. Then, if you have to, you can re-load it at any time.
