Ah yes, I was confusing Mhz with MT/s, my bad. Thanks!
I'm not sure I follow, they share the same unit MT/s

Configured Memory Speed: 1600 MT/s
If the internet (and my own experience) is anything to go by then
"Speed" is the maximum speed reported by the memory module. The
"Configured Memory Speed" is the speed that the module does run at.
The actual speed is at least influenced by motherboard, CPU and BIOS.
Your motherboard according to the dmesg is a MSI MS-7B84, MSI B450M
PRO-M2 MAX for humans, and the CPU is a AMD Ryzen 3 2200G.
The motherboard can handle 3200 MT/s RAM, more if overclocked. The CPU
supports max 2933 MT/s [1].
I'd say the 1600 MT/s is really low, I'd expect at least 2400 to 2800
MT/s but you won't get 3200 unless you're patient to play around with
memory settings and test to see which setting is still stable.
What I don't know how big a difference Single vs Dual-Channel makes.
Do you get the same output if you boot up another OS (on a stick)?
My million year old Thinkpad Yoga 370 (running Linux atm), reports both
values at 2400, 1600 is low.

It's reporting itself as PC4-25600, which is 3200 MT/s with a nominal clock
of 1600 Mhz.
The most obvious explanation would be that somewhere along the line Mhz is
being reported as MT/s or vice-versa.
Are you sure that's not the case?
