I got an m3 lite and was playing sonic rush, Finished level one then all the sudden I got the two white screen after a little while it came back with Fail to write to SDRAM, System must shut down. I reboot and open another game, and while loading it came back with the same error. I since reformat the microsd and rewrite all my games... I will have another play with it later tonight and see if the same error came up. I got 5meg free on the microSD at the time of the error, so I'm not sure if we have to leave a certain amount of spare space on the microsd. Has anyone seen this error before?
