It's kinda a moot point now as I've read that my particular revision of 
the board supports only single-channel DDR, but in case you are 
interested, the motherboard manual is here:


And on page 7 you can see the mention of Dual Channel with doubles the 
memory capacity of the board.  It is also further discussed on page 11.  
On newegg.com, the dual channel memory is sold as 512MB (256x2) and is 
about 10% more expensive than two single channel 256MB chips. 

Kingston's website has an interesting whitepaper on the advantages of 
dual channel and the performance gains that can be had from it (kinda 
like what hyperthreading has done for processors)


Interesting, but apparently not something I need to worry about with 
this board :)
