SDRAM over writing problem

[GMoha.1]

I'm using DISCO Board STM32F769I and use SDRAM in my application application

i note that when i write data more than 1023Byte the data is written in the next bytes as expected and also over write from the start of SDRAM (0xC0000000)

if there is any configuration make that problem happened ?

Like a rows or columns number is wrong. What does writing at 2048 and 4096 offsets do?

Who's initialization code?

I revised configurations and it was wrong configuration in columns number

i use configuration in system_stm32f7xx.c of
