Macbook Pro 10.6.8 RAM Upgarde to 8 GB

I bought a macbook pro 10.6.8 a long time ago and It's working wonderful. I couldn't be happier how fast it is comparing to any other windows computers that I have used in the past. As mather of fact, I have 2 Desktop and 2 Laptops.

I'm a programmer / Web Designer and a Social Media Expert and I was hoping someone can actually enlighten me with some advices regarding this type of mac when it comes to upgrades.

I use a lot of Adobe Programs those days and or some Video Production that require a lot of memory. I was happy with everything untill I decided to upgrade my RAM to 8 GB. Right now those are my computer specifications:

I decided to go ahead and buy 8GB or RAM from Amazon. I was very excited when I got them and decided to finally upgrade and this is what happend:

If I pull out the 2 memory sticks of 2GB each and remplace them with the new 4GB Stick each the computer froze. It restart and does not get pass the gray screen with the thing spinning for about 2 minutes before it froze.

If I only pull out one (1) Memory stick of 2GB and remplace it with 4GB, the computer works fine and it restart with no problems and I get 6 GB. After doing the Memtest, everything seems to be functioning properly. But the computer is not any faster nor I see any difference at all.

The only combination that does not function is if I use both 4GB RAM each then as I said it froze. I even called CORSAIR " The place I bought my RAM from and explain to them the ptoblem and they end up sending me another version of the 4GB but it's still the same problem " Frozen ".

A guy I've been talking to had the same issue and end up using 16GB and he told me that his Macbook pro works perfect with the combination of two (2) 8GB RAM together. Doesn't make any sens to me but it still works.

If anyone has encounter a similar problem would you please comment? Thank you all very much!
