How to increase speed of sdram

I have made custom board using Tegra TK1. It is working fine but on 204MHZ DDR frequency. because i shmood it and test was passed on 204MHZ frequency.
Now i want to increase the speed of DDR, is there any way to do it so that i should pass the rest at higher frequencies?

Hi, you should be able to generate CFG of other frequency as described in App Note in shmoo package.
