4GB Dual Vs. 6GB Single Channel


I'm not very technical in terms of making computers, and parts etc. I had a friend help me make this computer and I have a RAM question.

460GTX Graphics
i5 2500 CPU
6GB of Kingston HyperX 2000

1) In windows it is only showing that 4GB of my RAM is there (Control Panel -> System etc.). Since my mother board is a dual channel one is it not possible for it to show all 6GB?

2) If I can get the 6GB to show, would 4GB run in dual channel or 6GB run in single channel (I'm assuming 3 sticks must be run in single from browsing these forums) be better from a gaming point of view?

Cheers for help

    1) it should show 6GB in single channel
    2) Dual channel is faster than single channel and for gaming there is very little gain from 6Gb over 4GB.
