GA7N400P2 DDR DS vs SS for Dual Channel ??

I've read through existing posts...
Some say Dual Channel is no big deal.
According to chart in manual, to use dual channel with 4 sticks of RAM, 1&2
can be either DS or SS but then 3&4 slots MUST be SS! The designations SS /
DS don't seem important to the merchants selling RAM, so it's hard to find
single sidded 512MB DDR according to my experience. **Is anyone running all
4 slots with DS DDR RAM and if so, is the dual channel feature
functioning?** There are enough language barrier problems in this manual to
definitely question whether it means what it says!
