Macbook Pro (mid 2009) crashes after RAM upgrade
I just upgraded the RAM memory from 2x2GB ram to 2x4GB on my Macbook Pro mid-2009. A few minutes after startup with the new memory the screen freezes for 2 seconds, then the Macbook restarts. When it turns back on, it says "Your computer restarted because of a problem. Press any key or wait a few seconds to continue starting up."
If I remove one of the two new memory sticks and only run with 1x4GB the Macbook runs without crashing or any problems. Why does it crash with 2x4GB memory?
The new memory is "Macmemory corsair ddr3 cmsa8gx3m2a1333c9".
I also get this crash report when starting up;

I would strongly recommend to use compatible memory, at least.
As per Apple Support, it is 1066 MHz memory
Processor and memory
- ...
- 4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 memory; two SO-DIMM slots support up to 8GB
Also, I used to have such a 13 Inch '09 Macbook, I'm pretty sure it was MacBook5,5, and it was equipped with 8GB of RAM and 500GB SSD; it worked just fine.
