You normally get two 4 GB sticks to get to 8 GB of RAM, the 8 GB module will NOT work in a 2009 or 2010 MBP, only in 2011 and later MBP models.

It either works, or it doesn't. Try swapping the stick back and going back to the original configuration. If it boots back up with it, get a refund or RMA on your ram.

If it doesn't, quietly make a genius appointment. But if they suspect you screwed up the machine while putting in the ram, kiss that applecare buh-bye.

Oh, I didn't notice the specs in your signature. Take the ram back and get two 4 gig sticks like the previous poster suggested.

It might boot up, but then crash.

Not many vendors sell 16GB (2x8GB modules) kits. One is a no-name brand and the other is name-brand.

I tried the name-brand version and did memory tests (like how ANYONE should do when buying an expensive upgrade that might impact system stability). RAM tests failed during the third pass, and the system got 10C hotter. And the wrist area got hotter as well.

Many people reported the same problem.

So I lived with 8GB (2x4Gb modules). I'd love to run 2 VMs and still use Photoshop, but one VM at half the virtual RAM will do.

The 2012 model, with 16GB preloaded, is probably the most reliable deal, if one needs that much RAM. And assuming the 2012 model really runs that much cooler...

Assuming you're putting it into the MBP in your signature, it won't work. Your 2009 MBP can have a MAX of 8GB RAM. Using an 8GB RAM stick won't work properly in your computer. You could go get two 4GB sticks and it should work fine, but that's the best you can do. See if you can return the 8GB stick or sell it.
