ApertureScience:
I now have error messages regarding DramDqPullUpStrength and DramDqPullDownStrength. Im considering putting the old ram chips back and maybe diong a complete reball of U370.
ApertureScience:
I remeasured all 75Ohm termination resistors and some seem to measure around 38Ohm. So probably two lines shorted together. I took off all associated ram and no change. So complete reball of U370 it is.  Now waiting for some BGA stencils and solder balls.
rainbow:
Hi ApertureScience,
have you fixed the issue reballing U370?
Thank you
