Summary: Authentic memory. Arrived in sealed new container. Computer runs twice as fast now. I'll update this if anything changes. Be aware with RAM you'll want to closely match what you have. If you get a slower speed of ram, yes it will work. But your computer will slow down the other slot to equalize it. Please use crucial memory scanner to verify what you have already. I'd advise physically verifying too. Besides you're gonna open it up anyway why not practice.
Summary: It has been for me a sweet deal every time I've gotten something from Amazon Warehouse. The price is right and the product is as described. This ram chip has been no exception. I stuck it in and booted up and all is well. Good quality product at a good price is something that I like.
Summary: I purchased this for my Mac Mini... turns out it rejects it. So of course I was angry, since I checked and double checked to see if it were compatible with my Mac Mini. After cursing for a few moments... and wiped away the tears, I realized I have another computer! DUH! The PC laptop was to slow for Graphic Art/Web Development... after I put this baby in, she turned into a beast!
