DRAM errors would be issues with the RAM. I would make sure the RAM is secure in each slot, you can also try 1 stick of RAM at a time in each slot and see if that makes any change
Does this occur with each stick of RAM in those two slots?
You can try restoring your BIOS to default/factory optimized settings and try again and see if that would make any change.
Have you tried using a single stick of RAM to see if the system will post while only one stick in place?
When you open BIOS, when you select Save & Exit, there should be an option to Restore Defaults.
