Hmm...I haven't had any problems with my Slocket. I just had to set a jumper that forced 100Mhz+ FSB on it, and it hasn't given me any problems. I have a 700 Cb0 and I've run it all the way up to 933 perfectly stable, although I have recently backed it down to 840 because I was having some issues in higher detail graphics modes, probably because of my memory mostly.
I'm running 133 FSB with PC100 memory. The common line is usually it isn't good for anything above 124FSB, but by some miracle I got my machine going at 133Mhz FSB with PC100, go figure.
