Ok just to tell you guys, I just found out today that the Twinmos that they are selling at newegg right now are not BH5. They are some other kind of chips. I know this because my friend maxed out at 225 fsb with 2.9 volts. He tried raising the volts but it didn't help. When I did a search, I found out that only the speed premium versions are BH5. Here is a link to the speed premium.
And also, shorty if you cant find the Twinmos, get the ocz value BH5. It should cost around 105 dollars, which isn't too different from the 100 dollars the speed premiums cost. Those are BH5 also.
