System clock becomes slow in custom board imx6ul

We have a custom board based on imx6ul evk except that we are using lpdd2 ram. The problem is that if we use ondemand or conservative mode the system clock becomes very slow. For every 10 seconds update the board system clock updates only 3 sec. But as soon as we change board mode to performance mode the system clock works fine. In evk we didn't observe any such behaviour if we use ondemand or conservative mode in evk. The system clock works fine in every mode. What can be the possible reason for this behaviour in our custom board?
