Hello there,i have an asus laptop and i was upgrading the ram from 4g to 8gb..So before i bought ram,i have checked some of applications like cpu z,speecy crucial,task manager etc,all shows that i have ddr3 ram on board..but after i bought and set it up,i see my ram on application but not in bios and windows settings...So i ask asus customer service and they said that my laptop supports ddr2....I dont know what to do now,can someone help me??
