Triflexer :
can overclocking damage anything (ill probably google it)? also do u think this is a good ram (srry bout all the random questions). http://www.memoryexpress.com/Products/MX55746
It can if not done correctly. Overclocking anything increases the speed of the component typically creating additional heat and can cause instability. However if done correctly, it's pretty cool and not very difficult.
For gaming purposes, faster RAM doesn't really do much. There are a handful of games that may see a 5-10% increase but most games you won't see any benefit. Faster RAM helps in other applications. Same with overclocking a CPU.
