Actually comtech, you're forgetting one part of it. (someone already said this) Everything will run just fine at 133MHz EXCEPT the AGP. There is no 1/2 multiplier for AGP on the 440BX chipset, so your AGP port will be running at 89MHz at the least. (the spec is 66MHz) If I knew this when I bought my BE6-II, I wouldn't have gotten the CPU with a 133MHz bus. (I don't like overclocking. I just want it to work =) So, now I'm running my 800MHz CPU at 600, just to keep my bus speed at 100. The thing that actually caused me to do this was when my video started getting screwy on bootup. So, I bought a new video card and clocked the FSB down to 100. But then I noticed that there had been some thermal paste on the video card connectors. Oh well.. =)
