Overclocking is extremely serious matter, please do not think im knocking you or mocking you but the knowledge you seek for your first question tells me that overclocking is not for you yet. Its not something you just do from instructions you find or someone has given you. Please take at least a month to research all the factors risks, and consequences. Tom's hardware has tons of good reads on overclocking and prob for the pieces you have. Its really fun stuff and gets you great performance but it wont matter if you fry something
. Besides your first overclock would start at your cpu then move to your ram.
