Eric, Currently, duplicate ram in auto.c make the 4 ranks works. ( the MB that I'm using is EVT version. The HW engineer just did some rework to meet the production version).
Also I want to mix the 2 ranks and 4 ranks memory by change raminit.c, but it does not work. Please check the diff, maybe I miss sth. YH
