i'm sure this has been asked, but I just can't figure it out!

I have an E6600 with Kingston HyperX PC2 9600 and an ENERMAX 500W. I have DD water cooling on the cpu, and just bought two thermalright hr-05 and one thermalright hr-09 mosfet cooler. Before I got the thermalright pieces, I was running a p5w dh rev. 1.02G BIOS 2004 at max 340fsb stable either 1:1 or 2:3. This is at very high voltages: 1.6v cpu, 2.3v ram, maxed out the rest.
(I don't know much about MEMtest or other windows ocing software.)

Well, yesterday out of laziness I tried to remove the stock cooling's push pins without removing the board - and ended up breaking one of the MOSFETS!

I went to the market today and interestingly I found a P5W DH with a "1333 FSB effortless!" sticker on the box. I looked inside and found that it's 1.40G so I decided to try my luck with it.

Now, my question to all you 500+ fsb overclockers: What dividers and voltages can I use to go that far?!! Can it be done from the BIOS?

please help! This thread is overwhelming - if someone can point me to a relevant post here I'd appreciate it.
