Ryzen 5800x3D not boot with Ram in dual channel

Hello,

I have issue with booting PC with Ram in dual channel.  In single channel memory is working. With old procesor 2600x both Rams are working in dual channel. New procesor 5800x3d came from RMA and still the same issue. 

I got MSI 550B Tomahawk, Rams (G- Skill trident Z 2x8GB 3200MHZ or Kinstone Fury beast 2x16GB 3600 MHZ)

I loaded last version of Bios for my motheboard, set memory voltage to 1,35V.. Also CPU SOC Voltage to 1,06250V. Not help.  Switch off XMR profile, underclock rams and etc.

Also try all slot for rams, I only able to start PC in First slot A1. (5800x3d)

I put back my 2600x Dualchannel is running. 

Do you have any idea how to fix this at 5800x3D? 

Many thanks for advice.
