I have only removed caps from dead motherboards, and it was always a messy process. I suggest trying everything on another board first to make sure you won't run in to problems.

I'm just afraid that in your attempt to go even higher (270fsb ) you might kill the board. I've done it plenty of times. Fast... faster... faster... dead.
Are we talking voltage increases too, or did you just kill it by OCing? And are you sure it wasn't BIOS corruption?

I guess I'll stick to my measly 266FSB for now. This was my goal for a while now, and I hit it, so I'm quite satisfied.

270 is definately within reach, since I can consistently POST at 275fsb (d18) at a mere 1.8v VDD... So it would appear the sky is the limit.
