Hello TechPowerUp forums!

Just a simple question is there any difference between single sided and dual sided ddr4 ram in terms of performance ? What you think guys maybe they perform exactly the same or not ?

I noticed that my new ddr4 ram has memory chips only in one side on ram pcb.

err...wtf !?

Single sided dimm
...
3. can have chips on both sides of the stick


Double sided dimm
....
2. can have chips just on 1 side of the dimm (if the chips used are built in 16 arrays = 16x16 -> 256Mbit/IC, )
