Hey Ideas,

Have a look HERE, it explains a lot of this stuff. Also it has a lot of comments and arguments after it, this may explain a bit of it to you.

are u planning on getting ram? if so then how much do u want and what mobo do u have?

ecc and registered is for server mobos and you dont use them for regular desktop computers so you want to make sure that those say no.

and the lower the timings the better
