[SOLVED] IS THIS REALLY A DDR4 ISSUE?

[TIMSONGS]

I just finished building this pc
Msi b450 tomahawk max
Ryzen 5 3600x
Saffhire pulse 5700 xt
Trident z royal gold 2(8GB) 3600
EVGA 650 gold psu

The machine only posts if I use only one stick (second slot and secured)… when I add the second stick in slot 4 it refuses to post…
I removed the cpu and inspected it and no bent pins. And reseats without issues.
Bios is updated, and posts normal speeds and temps and voltage…
I replaced the tridents with Corair Vengence 2(8GB) 3200…… same thing so it is not the ram… and I doubt it is the cpu especially after I inspected and reinstalled it
Could it be an issues with the mobo or am I missing something?

Latest bios update installed?

yea, the mobo came with the latest version, I double checked it... some people tell me it is the cpu (bent pins) but i double checked it under a powerful magnifying glass.. even checked the mount.. all looks good... even cleaned them with a little IPA and a fresh dab of thermal paste. i want to to be the cpu instead of the mobo. i dont think Amazon will refunds the mobo and the cpu.. I wil call MSI tomorrow (today is Easter afterall) and then Amazon... other than that i am thrilled with everything.... next time I will benchmark everything BEFORE I build.
i also have EVGA 650 gold psu
TY for you reply

Yeah, I think you've nailed this down to the motherboard since you had the same issue with 2x sets of memory and double-checked the cpu.
