I have my system running now at 400fsb 333NB strap (8 multiplier) which put my memory at 1601MHz. I jumped it up to 425 and the memory went to 1700MHz. I will post my setting a little later as I want to ask the question about the fsb/dram ratio, it is set to 1:2 per CPU-Z. How does one go about changing this? As I increase the FSB I do not want to overclock the memory to far.
