[gofish]

I got these as a gift and am in need of some real help please.

Asus A7n8X Deluxe MOBO
2- 512 Kingston 400 DDR Ram
Anthlon 2100XP
Leadtek Graphics Card w/ vivo

I have the installed all in a new case with 3- fans.

I have no idea what to set up in bios to get the most out of the speed I would like and can achieve.

Any suggestions to this newbie?
