Hello, I am building a new PC in a month or so and am looking to get the ASUS P6X58d mobo and obviously the Noctua NH-D14. My question is what is the best ram I can get for this build and will let me use all my ram slots. I will be willing to go with 2 different brands if it means better performance and am new to OCing so I am not sure if I can oc the ram if I do that? My budget for all 12gb is in the $350-$400 range. Thanks!
