So I bought some new parts to upgrade my pc as listed:
MSI x670e gaming wifi ( i have latest BIOS update )
Ryzen 7 7800x3d
Kingston FURY Beast White DDR5 64GB (2x32GB) 6000MT/s - KF560C36BWEK2-64
I can only start windows with 1 ram at A2.
Can't start with dual channel A2 + B2.
Already tried A1 + B1.
Both rams work solo on A2.
Both rams fail solo on B2.
