Hi,
use dumpnorth to dump the northbridge, and compare your settings to the
original BIOS settings.
I have used dumpnorth in my code and got the REGISTER back.
Original BIOS settings means setting of some other BIOS other then LinuxBIOS. Is it possible to get the DRAM register values from Othe BIOS. I have AOPEN bios for my system.

I have checked my DDR SDRAM register programming and initialization progams with specification. It looks ok to me. If you want I can send it for reference.

I think you've got something wrong in your DRAM programming.
