Same memories (RAM) dont work as dual channel?

[cnseref00]

I just finished building my first pc. I have 8 + 8 Hyperx Fury 3600 mhz 17 cl rams. I bought them from the same seller but not as a "dual kit". The specs are all exactly the same, YET THEY DON'T WORK AS DUAL CHANNEL. As you see in the screenshots, they are both placed correctly (on A2 and B2 on motherboard). I checked slot and replaced them again. The result is the same. I changed clock speeds on the motherboard to 3000hz and 2400hz, nothing changes.

 

motherboard is: Asus prime b500m-a wifi

 

ryzen 5 5600 cpu

amd rx 6750 xt gpu

if the memory is in slot A2 and B2, it's either operating in dual channel, or not operating at all.

 

Where in the screenshots shared do you see that the memory is in single channel? Everything checks out to me.

But I don't see "dual" writing anywhere. And it says "single" in the ranks bubble at cpu-z. See for exemple the task manager:

Make sure to use the quote button so we can see your responses.

 

Single and dual rank has to do with how the ram dimms themselves operate, for more info have a look at this video:

it features a brief explanation towards the beginning of the video

 

As for what else is shown, in the Memory tab of CPU-Z, I see "2x64 bit" under "channel #", DDR4 is one 64 bit bus per dimm, so 2x64 bit would be dual channel

It's in dual channel according to cpuz memory tab.

 

That's 2x 64bits = dual channel.

 

Single rank means memory chips on one side of the memory stick.

If it's dual, then it's okay. My bad... Thanks a lot
