It's at least conceivable that an E4300 BSEL-modded to 1066MHz FSB might give you access to the 2.5x/3.0x memory multipliers, no?

Given Gigabyte boards' previous reactions to the BSEL mods I'd imagine it's not nearly a sure thing--might not even POST at all--but it seems like it might be at least a reasonable possibility.

In any case, an impressive board, especially with the potential for future BIOS feature improvements.
