I'm about to drop some bucks for a P4 Northwood system, and this topic has me curious. It's well understood that your 1.6a is "guaranteed" to his the magic 133fsb, and you can go from there, but how likely is it a 1.8a will be able to hit 133? It seems like SOME people are having trouble with it, but from scanning this board I can't seem to find a person who specifically posted about their 1.8a. Any of you have war stores to share?
Oh, and another thing that I?ve been wondering for a long time:
>>I am at 2.52ghz right now...140fsb, which only makes my pci 35.... To take a 1.6ghz and do the same you will need a 157.5 fsb and that puts pci at 39.3mhz...plus that really pushes memory unless it is good pc2700 ddr....
At extreme speeds you can drop the PCI multiplier down and run it at 31mhz or so, but is the problem the PCI bus is going too fast, or is just the fact it is out of spec causing the timing issues?
Thanks in advance,
