RAM has to run at the speed of the slowest, so in effect, you have 4GB of DDR2-667. That will limit the FSB to 1333MHz. Lower the CPU multipler from 12.5x to 10x & raise the CPU freq from 200MHz to 333MHz. That will put the CPU at 3.33GHz. Do you you've gotta do to keep the RAM running at 667MHz.

You have to make sure the memory does NOT overclock. That's why I wrote - "Do you you've gotta do to keep the RAM running at 667MHz". I figured if you owned a board like that, you knew how to set it up.

Make sure both DOT Control & EIST are disabled.
Set the CPU FSB Frequency at 333MHz.
Set the CPU ratio at 9x **(this is a temporary setting)
Set the PCIe at 100MHz.
Set the PCI at 33MHz.
Disable all Spread Spectrum settings.
Set the FSB/Memory ratio at 1:2

The above settings will run the CPU at 3.0GHz at 1333MHz FSB with the RAM running at 667MHz. If you want to increase the CPU speed, simply raise the CPU ratio from 9x.

I know how to set it up, but some how the things that we've tried so far aren't work. I followed exacly your instructions, but the same exact thing happened. Reboots but not screen, not light on the key board, and I had to clear the cmos to have the system back. I also would like to tell you that I do appreciate your effort to have that thing overclocked. Please let me know if there is something else I can try.

As an experiment, use all the above settings except the CPU ratio....set the ratio at 7x. That will put the CPU at 2.33GHz. If you're able to boot into windows, the problem was most likely the CPU voltage setting. In that case, set the CPU voltage to 1.38v, then try raising the CPU ratio back to 9x.
