Hello,

1) Confirm your memory kit part number

2) Does the issue persist with Optimised Defaults? (No XMP or any parameters changed after clearing the CMOS

When I clear CMOS not modify anything default ram speed 2666 it boot up but When I enable the DOCP  default to 3200 not posting this happen to me 2weeks ago

Have you updated the UEFI? Reset to optimised defaults and use EZFlash to update

Yes  I'm on the latest 4002 bios

Last night I try 2666 to 2933 it boot up when I try 3000 negative this maybe a sign of faulty ram slot? 

This month my motherboard is 3yrs old at time of my purchase  is this still cover my warranty?

Sounds more like DRAM instability, but your case is a bit strange. Your original post said "stopped overclocking". Can you confirm if the DOCP profile was working and what changed leading up to the issue?

[ryzen23]

i can confirm that DOCP profile is working when i place the ram to slot 2&4 i can play for hours with this settings

Then you’re all set. Adding additional modules or combining memory kits is not supported. DIMM slots A_2 and B_2 are the correct slots for two DIMM configuration.

I can overclock on that slot for 2years almost 3years then suddenly Not posting maybe time to upgrade
