Blacklabs, please don't misunderstand me buddy, but you really should post your questions here, in this thread.

You're restricting yourself to my knowledge alone by sending PMs to me. I'm certainly not the last word in PC technical help.
Now, if you say that you built the computer yourself, from scratch, then you shouldn't need a manual. You should know your PC more comprehensively than I know mine. Besides, the parts you ordered/purchased to build the PC with, all come with their own manuals. I have yet to purchase a computer part that doesn't have some type of nomenclature associated with it, even if it's just printed on the box.
No, you shouldn't have to upgrade your MoBo in order to add more RAM but, you should be more specific in your questions/replies. The info I'm getting from you is very vague. Please post your questions here so that others may assist you also.
