Is DDR2 good enough for a Minecraft Server?

Its doubtful. Depending on the server, playercount, and chunks loaded 8GB will not be enough (let alone the slower speeds of DDR2).
If you are aiming for such a high player count you should have more overhead RAM.

Another thing to consider is the processor being used, if it only support DDR2 its probably not great.

Do you think low end DDR3 would be enough?
