My understanding was that dual-channel needed at least PC3200 RAM (400 
MHz); the difference in price is probably due to the fact that if you're 
not running in dual-channel mode most mobos fall back to PC2700 speeds 
(333 MHz), so if you're not running dual-channel there's no point in 
buying the more expensive PC3200 RAM.  The fact that you need 2x sticks 
of identical RAM for dual channel does not add as much to the price as 
the difference between PC2700/PC3200.
