Yes, maybe different FSB has same for you, but not for me. A quick multi change to lower cpu speed @ same FSB and no problem. If it was voltage, setting 1.52 @ lower cpu speed would create same behavior..in my board it does not, ergo it can only be current. As to why the current induces this behavior is the only question, and due to the "EPU" that no other board "HAS" (at least does not install driver for this), I think we can call it case closed, and must await updated driver for "EPU". I didn't spend the last 24 hours on this for nothing, thanks. ;) :lol2:
