According to asus cpu-compatibility list, your cpu is already supported.
You might check the exact cpu-type and dual channel working with the cpu-z tool.
If dual-channel is not working try to change the ram-module positions and settings.

oder auf deutsch:

Laut ASUS Kompatibilitäts-Liste wird die CPU unterstützt.
Der exakte CPU-Typ und die Dual-Channel Funktion läßt sich gut mit dem Tool CPU-Z
auslesen/prüfen.
Falls der Dual-Channel Modus nicht läuft, hilft nur rumprobieren mit der Speichermodul-Bestückung.
