How to enable dual channel memory?

[Fer DLC]

Hello , i just ran the user benchmark test and it said my ram is underperforming and that it's clocked at 1200mhz when the ram is supposed to be at 2400mhz. I don't know why this is but i went into my bios and it said i have single channel memory so now im wondering if its because of that. How can i enable dual channel memory? Do i just place one stick of ram into the first slot and the second one into the 3rd slot? There are 4 slots in total, my mobo is the Ab350pro 4 and i have 2x4 ddr4 2400

DDR# (DDR, DDR2, DDR3, DDR4), the DDR aspect stands for "double data rate" . So 1200MHz is actually x2 = 2400MHz.

Dual Channel is not the same thing,. If you have a matching kit of RAM, you populate whichever slots are designated on the board for Dual Channel operation (detailed in your manual).

Those are the correct DIMM slots for bank 0 so it should work. Dual channel isn't something you turn on. Its the kit you buy and should be paired by the company to be enough alike for it to work. Ryzen tho is a bit harder on RAM so you may need to get faster RAM to get the top speed 2667 plus dual channel. Most get 3200 to make sure they get 2667~2933. You should RMA tho as the RAM isnt working in dual channel as that is odd for a kit.

Try to swap them around to see it changes.

You need a matched pair of DDR4 DIMMs in memory slots DDR4_A2 and DDR4_B2 if you want dual channel mode.

Memory slots DDR4_A2 and DDR4_B2 are located at the end of each channel's memory bus. Filling these two memory slots first is recommended to prevent signal reflections on the memory bus that can cause memory errors/problems.
