msi b450 tomahawk max ms-7c02 rev 1.0

[Davemack69]

Have a msi b450 tomahawk max no boot dram led lit.
I don't have any voltage on data lines to ram slots my working board has around 0.38v on data lines this is with no ram installed on both boards.
I have a tested in diode mode and data lines read same on both boards.
I have schematic and have tested voltages on all rails concerning the dram.
Have I lost a voltage somewhere on a buck convertor or is cpu in sleep state maybe?
Any ideas?
