What a difference a brand makes. I previously previously brought PNY memory from a different store. Put Both memory modules in my MacBook (mid 2010), the computer did not boot up. After several tests including putting the original memory back in, it was clear that PNY memory modules were defective.

After returning them to the store and getting my money back. I decided to try out the Corsair Memory as it was recommended by a friend. I after looking at several other sites for this memory I ended up getting it from Wallmart.com using the site to store option. (Unsurprisingly Walmart had the best price.) The memory arrived to the store 2 days before promised date.: ) This despite Hurricane Sandy hitting the Northeast last week. After installing this memory my MacBook booted right up.
