Ok I flashed my 9800np to a 9800 pro and since then I can't oc the cpu as much. Something else: when I'm in kazaa (downloading patches, demos and perfectly legal stuff of course ), the system is extremely slow, especially inside kazaa. Drop down menus take a couple of seconds to appear and when I drag the mouse over the options it is also very slow. At that point I'm suspecting the psu to be at its limit. So I flashed my card back with the original bios and now kazaa is perfectly fine. I haven't tried ocing more yet though. The reason I think the psu is at its limit is because what the 9800 pro bios does is increasing the voltage to the gpu and the memory, thus increasing the speed of the card, thus demanding more juice to the psu. So, do you guys think a more powerfull psu would cure the problem ? Do you have anything else to suggest ? I do not think it is dying, I just think it can't provide that much power.
