I do not know the Yopy, but since you mention changing row/column values, I guess you might have replaced 2 128Mbit-SDRAMs with 2 256MBit-SDRAMs.
In this case, apart from MDCNFG, you might also need to halve the refresh-rate (value in bits [15:4] of the MDREFR-Register) to account for 8K of refresh-adresses rather than 4K with the 128Mbit types.
