Ram timings: Is there a difference between 9-9-9-24 and 9-9-9-24-2n

[carl1864]

So is 9-9-9-24 and 9-9-9-24-2N the same or different?

I have a Asus Ma785TD-M EVO motherboard, with 2 2gb sticks of g.skill ripjaws DDR3 1600mhz model F3-12800CL9D-4GBRL. The sticker on my ram says that its timing is 9-9-9-24, however their specs on the website say it is 9-9-9-24-2N (although that same page is showing the specs of 3 different sets). So I don't know if one of the sources is wrong, or if its the same thing or what.

I want to add 8 more GB of ram (2x4gb). I found a set of the same brand of gskill ripjaws model F3-12800CL9D-8GBRL which has 9-9-9-24-2N timings. Would that be fully compatible even though their is a possible discrepancy with whether my current ram is 2N or not?

I also found a pair of Corsair vengeance for the same price which is only listed as a straight 9-9-9-24, model CMZ8GX3M2A1600C9B.

I need some memory soon, and am confused which to buy.

Those rams should work fine together, the only difference is the size of the modules (4GB and 8GB kit). The 2N could be referring to the command rate (usually 1t, 2t)
