I have a MacBook Pro 17" Mid 2010 which normally supports 1067 MHz RAM. I needed more memory and installed 2 x 4 GB RAM 1333 MHz modules which - as expected - also work with 1067 MHz.
After a couple of weeks the display started flickering and showed disturbances similar to television statics for a second and then returns to normal. A couple of weeks later this happens more frequently like every 5-9 minutes. It especially occurs when a secondary display is attached.
Could the RAM modules cause this or is my display card just dying?
This is how it looks like: video
