Mixing dfferent desities of DDR3

[bc7009]

I currently have two 1GB sticks of Crucial DDR3 10600 installed. I want to add two 2GB sticks (also crucial) to increase my total amount of RAM to 6GB. The modules that I'm looking at buying have the exact same voltage and CL as those that I am currently using. The memory FAQ on this forum says that this should not be a problem, but the crucial website says that mixing densities will disable dual channel compatibility. Who is right?

Some additional info-

Here are the modules that I currently have: http://www.crucial.com/store/partspecs.aspx?IMODULE=CT2KIT12864BA1339

And I want to add two of these: http://www.crucial.com/store/partspecs.aspx?imodule=CT25664BA1339

They will work in dual channel mode.

Thanks, I just didn't want to blow $80 on RAM to not have it work properly.

Note that even if they didn't work in dual channel mode, the performance difference wouldn't be huge: http://www.tomshardware.com/reviews/PARALLEL-PROCESSING,1705-11.html?xtmc=dual_channel_single_channel&xtcr=5
