I've tried looking through the forums and couldn't find a similar thread. Hoping someone has found a solution though. I've just upgraded my MacBook Pro 6,2 (new 15 inch i7) to 8GB of RAM *Cas 7 PC-8500 DDR3-1066 from Mushkin) It works fine, has passed all of the Rember tests but seems to have some kind of conflict with the Intel integrated graphics card. As soon as I'm running off shared Video RAM I get terrible tearing and static on my screen. When I switch over to the nVidia discrete graphics everything works fine. The strangest part is that once the computer has been awake and running for a few minutes everything seems to settle in and work properly. Doesn't seem to matter how many times I restart or clear the Parameter RAM. Every restart or wake from sleep throws the integrated graphics into hysteria. Any ideas? Anyone?
