It really doesn't seem as if the BE6 has any more FSB settings than the BX6 II - they are just different. For Celeron overclockers as well as P2 overclockers that don't have a hope of going beyond 124 MHz, the BE6 will be a nicer alternative. But for those P3 overclockers, the slightly more advantageous FSBs of the BX6 II could mean the difference between 20 MHz or more in overall clock speed. It even affected me. However, I have no such option with the BE6 and am left to hang at 558 just like everyone else.
Stability is solid and the price is quite competitive.
Bad Stuff Finicky. That's how I'd describe the board to an overclocker. It probably will work, but it may be interesting getting it to. Also, since the FSB settings are different, it may be an unpleasant surprise to an overclocker used to a particular speed. The 3 DIMMs make this a bit more like a BH6 II rather than a true upgrade to the BX6 II, but that's only likely to affect the more picky.
