I have two types of ram in my computer right now. Different brands and different speeds. I think one brand is PNY and the other is Samsung. One is PC3200 and the other one is PC 2100 or PC 2700 not 100% sure. How could i make the ram run at max potential using dual channel mode. My motherboard does support it. Its an Asus A7N8x Deluxe. Which ram should i put in first? Do i just need to put 1 stick of ram into slot 0 and the other stick into slot 2?
