How to run a 200 fsb in ga-7vaxp?

I've got the said mobo with an athlon XP 2400 Trh (running 133 FSB) and 512 Mb of crucial pc2700 memory. Just got my hands over a kit of 1Gb of Geil golden dragon memory. I know that I won't obtain all from this memory without a dual channel mobo (nforce2). With my previous memory a I just only get to a fsb of 140 before locking up my computer (I know too that this mobo is not a great overclocker). Has someboy experience with this mobo and can tell me how to get to and fsb of 200? Could I lower the multiplier to 10 (now it's 15x133) and set fsb to 200? thanks
