My550e runs 787,1.7v,143fsb on a msi 6309, 128 megs mushkin athlon memory, with the bios set to enable spd, otherwise it turns unstable. The Alpha pal6035 is ducted to an 80mm pc power and cooling silencer fan blowing out the back of the Antec sx1030 case..If I was willing to endure more fan noise, it would probably run faster. Poking around the different forums, I've noticed very few complaints about 550e's not reaching 733, I suspect that they really are exactly the same as the 733eb, with a different label and a better price. I try not to criticize Intel's so-called marketing strategy, it makes all this inexpensive overclocking fun possible. ALPHACOWBOY-your p3v4x probably supports the RAM running at fsb-33, check the manual and the bios, try it to see how far your particular processor can go.
