I have 4 4gb sticks of g skill ddr4 ram for my asus maximus viii hero. In my mobo user guide, it says the order of dimm from left to right should be A1, A2, B1, B2. How do I know which RAM stick is which? They all look the same to me.

I don't think it matters.

You're going to populate all four slots so it doesn't matter what RAM sticks go where

Alright, but just out of curiosity, how do I tell which is which?

The thing here is if you only had 2 sticks you would want them on different letters to enable dual channel, but you are filling all slots so it doesnt matter just place them and be happy.

the A and B are the memory channels. Ram doesn't have a specific channel (unless you were mixing ram, but you're not) so it doesn't matter which goes in which

Channel lanes are usually indicated by the letter:  A = 1st;  B = 2nd;  C = 3rd; etc.
The position in the lane is indicated by the number: 1 = 1st; 2 = 2nd; etc.
If you had 3 channels with each having 4 slots,  You wouldn't want to organize 3 identical sticks as A4, B2, C1.  Some Mainboards won't even allow you to do it.  It creates extra latency and uses extra computing power if your system has to sort this out.  It can cause all sorts of other timing problems.  So in an example of 3 lanes with 3 matching sticks with 4 slots per lane, you'd either choose A1, B1, C1   or  A1 A2 A3.  Having even number of stick across the channels provides more efficiency, so that's usually the best option.  However, always check the manufacturer's recommended setup or the consult the manual.  There may be a specifically more efficient way, or they may have equally working configurations, IE: B1 B2 B3   or C1 C2 C3, etc.
