Video flickering using DMA Controller with D5M on DE2i-150

I'm having trouble when using DMA Controller to buffer video stream captured from D5M on DE2i-150. 


The video will get flickering if I buffer video over 320x240x16bit resolution. However, 160x480x16bit resolution works fine. 


I think the problem associates with the RAM, both SDRAM and SSRAM. I can't find a configuration for these RAMs to get it work. 


I wish to make it works at 640x480x16bit resolution.
