I've got an Asus P5N-EM HDMI motherboard. When I run CPU-Z, it says my Memory is Single Channel. Currently, i have 2x2GIG Kingston DDR2 ram modules installed.
These are the screenies from CPU-Z:
Note: Both slot #1 and slot #3 have the same data.
Should I be trying to go dual channel? Should I care?

Looking at your board it appears that Slot#1 and Slot#2 (colored black?) should be used for the memory -- this ASUS board has 3 memory slots instead of the usual 4 and they are organized differently. Alternate is not right here.
A good article discussing Dual-Channel RAM,
Everything You Need to Know About Dual Channel
Finally, this is described with more words in the article,
If you have a motherboard with 4 slots, and you own two similar memory sticks compatible with your board, it is critical to place them on the correct two slots (usually alternate slots). The board is wired to use them in dual-channel mode correctly on these placements. Suitable slot pairs are usually colored the same to remind you about this.
So, YES, you should care. You have the right memory (DDR two matched units) and you are running single more just because of incorrect memory placement.
