Hmm... my FSB is 445, though I certainly can't get much out of going x10. I'm not really talking to you, jake, I just didn't think getting past 400 was such a marvelous feat at x8 as the other guy was saying. Would love to crack 3.6 24/7 stable but I'm not sure it's worth it when I've already been given a gift of a batch number and riding out 3.56 I'm not exactly bottlenecked.
Check the database on the forum here, under the Intel section.. you wont see many submissions for the E2xxx's much past 380mhz FSB..let alone 400+.
You guys should feel good to have such wonderful CPU's.
- I might have been happier with my E2160/2180 and 2200..had any of them run stable beyond 400mhz. *le' cry 'le whine*
