i repaired the pin. installed it on the socket on the mainboard and installed the rams. same issue happened.
so it has nothing to do with the pin i guess.
maybe its about incompatible ram? or is this really a defective cpu?
is there anybody out there facing the same problems?
Since you replaced the Motherboard and still has the same issue than most likely it is the CPU that is defective.
Best way to eliminate the CPU is by installing it on another compatible Motherboard and see if Dual Channel is recognized. Or install a different CPU on your current Motherboard and and see if Dual Channels work.
If possible maybe you can burrow a CPU from a friend or family to test your motherboard.
You can open a AMD Warranty Request from here: https://www.amd.com/en/support/kb/warranty-information/rma-form
If you CPU is still under 3 years since you last purchase it, AMD Warranty is still in effect.
no i have nobody who can burrow me another cpu. we have still lockdown here every computer hardware shops are closed. nobody is around i only can online buying new motherboard. i purchased another ram (hyper x predator 16gb 2666) who is listet in the qualified list from asus prime b350 but i faced the same issue. no dual channel mode. but i think i ve gone a long way with this amd ryzens.
i do not have the money to buy another hardware all the time and the cpus are almost 3 or 4 yrs old and i do not have warranty at all.
i think i will buy another platform and hope i will no longer have such issues like that. of course i ll buy complete other bundle (board, cpu, rams)
purchased another Mainboard with a B450 chipset. i put it together with the 1600er Ryzen 5 and 2 moduls 8GB Hyper X Predator 2666 and the computer is working with it now. so dual channel mode is now working and i am totally happy.
no failures at all right now.
so the cpu was not defective it was probably the mainboard. the ram is qualified in asus list and it runs perfect now.
its a Asus Prime B450-Plus Bios Vers. 2202 AGESA Combo-Am4 188.8.131.52 07/14/2020
i hope this will help others facing the same problems.
It is hard to believe you went through two defective Motherboards.
You mentioned that you installed the Ryzen on a different Motherboard (2 DIMM Slot instead of 4) with the same exact problem which suggested that the CPU was defective. Which through me off.
Now you again got another new Motherboard and everything is working. Really strange.
Anyways you might as well marked you last reply as "Solution" since it fixed your issue and to let other Users know what you needed to do.
Good troubleshooting and take care.
yes i have 2 motherboards with chipset a320 (which has only two dimm sockets) and the other one is a b350 (which has 4 dimm sockets) but they both had problems with the rams and the ryzen 5 1600.
now i bought a prime b450-plus (4 dimm sockets) and the dual channel mode with the hyper x 16gb 2666mhz and the ryzen 5 1600 is working without any failures. i am writing this with this system now. and i am online since a couple of hours including gaming and other things like surfing, video watching - no freezes or crushes. its working perfect.
. maybe its a limitation from the 300er chipsets. while b450 is working well. the ryzen 5 1600 is not defective. i am so glad.

maybe it had something to do with the chipsets of the two 300er chipsets boards (while a limitation ? ). idk.
but i am glad to switch the board to one with b450 chipset. first i thought to buy one with x370 but instead i go buy this b450 and that was maybe the best choice.
so to all others having the same issues: make sure u checked the dimms in the qualified lists from the motherboards manufactory. (in my case asus). I recommend using RAM that the processor also supports, such as the ryzen 5 1600 dimms to 2666 or ryzen 5 2600 2999 and so on. I think then you don't have to worry, because I find the oc rather unnecessary because in my opinion that doesn't really matter that much speed.
