Unfortunately, disabling Static Read and Dynamic write Control doesn't change the situation. Prime95 still shows errors.
Why don't you check first if you underclock the the memory it also crashes. It might be very well possible that your CPU cannot reach the 450FSB you are trying to accomplish. Possible you need to raise CPU related settings in order to reach 450FSB; just underclocking the CPU alone will not be enough if the voltages necessary to get to 450FSB aren't set.
