Pros: Potentially large RAM upgrade. Great discount. If it works, it is a great deal.

Cons: If it does not work, it is a waste of alot of money. Delivery was a little slow, but this is partially due to making the order on a friday evening.

Overall Review: When I recieved the memory I was excited to try it out. When I installed both sticks my laptop would not boot. I have a toshiba satellite l505d-s5965 and recently upgraded to windows 7 64-bit just so I could install this RAM. However, when I keep one of my original sticks in and add one of the new 4GB sticks it boots, but it will not boot on the new memory alone, not on 4GB or the full 8GB. Crucial showed that this RAM is compatible. It also seams like the RAM I recieved looks different than the images on this site. Did I get the right RAM? I am not sure what I should do about all of this.
