In your bios, there is a "memory remap" setting. You may need to set this to "enabled" It's under "Advanced menu" -> "Uncore configuration"

You may also try re-seating your RAM.

This (some RAM not recognized) could also happen if any pins on your CPU are bent (they sometimes get bent while you install them).
