I found that we did not turn on the fast raster when we decide the slow raster size last night. So I take two quick third arm run 41042 and 41043 to check this. With a 2x2mm fast raster on, the slow raster will see some hot spot when it reach 1.05V. So I recommend we run with 1.0V slow raster with fast raster on when we go to production.
