STM32F7 internal SRAM Access

I am using STM32F746IG. This has 320KB RAM - 64KB DTCM + 240KB(SRAM1) + 16KB(SRAM2)

When my program uses 64KB, all the data is stored in DTCM and it all works fine. But when exceeds 64KB, data is stored in SRAM1(internal SRAM) and program no longer works. I have all code in flash (0x08010000). I assume access to internal SRAM is always enabled. Is there anything to be enabled, when RAM requirement is more than 64KB?
