I have changed the memory in my MacBook Pro December, 2010.

I have put 2 4GB Samsung Rams in it. The ram: 2X 4GB PC3-10600 DDR3 1333MHz 204 Pin SODIMMS

It started freezing when I use Lightroom and Photoshop or I watch movies on the computer. It usually freezes after 10-20 minutes after starting it. Everything runs smoothly until it freezes...

What did I do wrong?

Help!!!

Thanks!
Otto
 
You may have just got some bad RAM - it happens.

First check that the RAM is seated properly (pushed in all the way).
Second, test the RAM http://guides.macrumors.com/Testing_RAM.

If neither one of those is conclusive, put your original RAM back in and see if the problem persists. Then swap out one stick at a time.

I have put the original back and the Mac works without any problem!
The ones which I had a problem in my mac run smoothly in my friend's PC laptop!!!
Should I get a more expensive pair of rams... and try again?
 
If they don't work, send them back and get replacements or sell them to your friend. No need to buy more expensive RAM.

RAM price has little to do with quality, bad sticks happen, they are mass produced and quality assurance has gone down quite a bit lately.

Just exchange it for 8 GB of 1066 MHz RAM - that's what Apple specifies.
