Well, color me impressed. Just finished getting my 8320 stable at 4.4GHz with my new Sabertooth. Using the recommended Digi+ settings in the guide with a +0.025 vcore offset (1.392-1.404v under heavy full load). Similar speed and vcore settings on my 970 board would result in 75*C core and +80*C socket temps. Now I'm seeing 68-70*C core and 70-73*C socket (same cooling setup).
