Guys, I've tried various ways with little success so far. With hybrid mode of course. Auto, per core and all cores. Cool n quiet disabled. Had the most success on all cores getting as far as windows momentarily and with no voltage added, but I get 2 or 3 windows error message boxes popping up as it gets to my desktop, and then it reboots before I get a chance to open cpu-z to see what it says. I also get a short buzzing noise when or just before it gets to windows, like its coming from the motherboard perhaps. Also, it sometimes shows a messed up screen of colours momentarily just after saving settings in bios. I've tried undervolting it from 1.34v to 1.3v and I had to reset cmos with jumper pin because I couldn't get to bios. I've tried increasing the cpu volt from 1.34 to 1.4v. Should I do something with any of the NB voltages, if so which ones? NB cpu vid, NB voltage, or even SB voltage? This is my screen after I changed the cpu voltage to 1.4. I'm on stock cooler till aftermarket arrives and so I need to watch temps carefully with any voltage increases. Cheers.
