Channel B stopped working

[Arlotami]

Specs-

Ryzen 7 3700x

16 GB  - 8x2

X570 gigabyte aorous pro wifi

 

Issue-

I had the ram installed in 2a and 2b slots and suddenly the stick in 2b stopped showing from yesterday.

 

I moved it from 2b to 1a and i see 16 gb now but its single channel..

 

Things i tried-

Reseating the ram.

Reseating the cpu.

 

Then i changes the cpu to a ryzen 3 apu and put the ram back in 2a and 2b, both showed up just fine.. at this point i was ready to accept that for some reason one of the memory channels in my 3700x is shot..

Just for kicks i installed the 3700x into a asrock b450 pro (this is the pc i took the r3 apu from) with 16 gb in 2a and 2b and both show up.

 

I am completely lost as to whats happening here installing 3700x back into x570 still does not show anything on channel b.

 

Any ideas/comments?

2A and 2B are the correct orientation per the manual...... Did you read it??

Yes they are in the correct orientation, i have had the system running since September last year, the issue started recently.

Time to RMA the board (X570) Your diagnostic was spot on. Cpu works in another board, Cpu is fine.
