Need overclocking advice.. HELP!

[FlyingHamster]

My 2 x 256mb of Twinmos pc3700 43D ram came in today. I tried everything I could to reach my goal (240 fsb) but could not even get close. Im having trouble getting to even 11x220.

I have done no mods to my board, Im using the 10b bios (I think, it says 6A61BA1BC-10 in bios), and have a Zalman NB32J on my nb and a copper heatsink on my sb. My mobo is about 2 months old and has a plastic lever on the cpu socket. if anyone could do the vmem mod for me I would love them 4ever.

My question is simple, what do I need to do to hit 240 fsb? should I flash my bios? reformat perhaps? and most importantly, what should my settings be in my bios? Im not sure what to set in the SoftMenu, nor in Advanced chipset features. what should be enabled and disabled?

I was hoping that with this new setup I would be able to hit at least 240x10. Any suggestions are greatly appreciated..
