As I said in my original post, you may have had luck with Crucial ram yourself, but if you do a bit of a search on line you will find plenty of compatibility issues with the new MB and Crucial sticks. In my case, the MB ran great, but I had that intermittent black screen when trying to wake the MB from sleep. So, if you rarely put your MB to sleep, you might not even know that your ram is incompatible. I didn't mean to imply that Crucial was the only brand that is still showing incompatibilities with MB, many ram brands still are showing problems. So beware. Crucial stands behind their product. I picked sticks guaranteed compatible with the new MB, and they were not. These are not "defective" chips; they are incompatible ones. If you are buying ram be absolutely certain you are buying from someone you can return it to, and test it for a couple of weeks, especially waking from sleep before you can be certain the chips you have are actually 100% compatible. Personally I'm surprised we are still seeing incompatibilities especially with a big "reliable" brand like Crucial. There's frankly no excuse.
Mine sleeps all the time. I barely ever shut it down. You can find people complaining about anything on the internet as people barely ever go online to say "yup, it just works."
Anyways, this isn't really a Crucial thing, it's an Apple thing. They set the timing limitations too strict.
