Are these two RAM stick compatible?

Solution
When it comes to memory's there are a few things to keep in mind:

1. Always install memory sticks from one memory kit. They are matched together.

2. Always make sure that the chosen memory's is indeed supported by the motherboard and its processor.
Different types of memory's, different frequencies, timings etc. the memory stick with the lowest speed will always set the speed for the rest of them.

3. Very important that the voltage of the memory are supported by the processor; meaning that a memory stick with to much voltage let say 1.7V when the processor spec. clearly says 1.5V - will damage and shorten the processors life span.
