stability failure I would say. If I set it to 3.8 or 3.7, when I look in CUPID it still says only 3.6 and I find that very strange. I've oc'ed my Ram to 750mhz now but still no change. However if i go in to my Nvidia tools to overclock, if i set the cpu to 3.8 my screen will just freeze and i cant do anything. I've tried higher voltages, but still no change. My temprature's never go above 60% either.
