I suspect that acer is the make of your computer rather than the mobo.

In most cases if you are going to have two slots filled out of the four available they should be in the matching colours to enable dual channel.

It won't matter if you put them in the wrong slots because when you switch on your computer the boot up screen will show whether or not dual channel is enabled.

Will your motherboard utilise the faster speed RAM?

Do you have a 64-bit system with a 64 bit OS? - if not your OS will only see somewhere around 3.5 GB RAM, due to address space limitations.

Your motherboard manual should help in both cases, and in which slots to use to enable dual-channel working.
