Which Ram Should I get?

the second is DDR, and the first is DDR2. Your board takes 4xDDR2 and 2xDDR it looks like. I would get dual channel DDR2 personally (this is not either of the choices you made), but if you are determined to get one or the other, I would still say DDR2 because it is faster, though timings aren't available for either.
 
Its not like DDR2 is a massive everyday performance penalty either so DDR2 definitely a safe route and will also be reusable (or greater chance) for future machiness
