I have a Asus a8n sli delux mobo 939 with a amd x2 4400 oc to 4600. I recently purchased this ram http://www.monarchcomputer.com/Merc...duct_Code=140363&Category_Code=Unbuffered_OCZ and it should be running at 500mhz right? i put the voltage up to 2.9 but according to 3d mark o5 my ram is only running at 333.0mhz How do I fix this?
