As Ron said, Without docs you have a very hard road ahead.
The following JEDEC document may help you somewhat understand what is
going on. It pretty heavy reading though.
Free but you have to register with the jedec site to get to the downloads.
DOUBLE DATA RATE (DDR) SDRAM SPECIFICATION:
The mfg datasheets and app notes for the ram chips on your DIMM may also
help you understand what you need to do to make the ram talk.
