I currently have my XP2000 tbred (not sure if it is an a' or b'). at 1.85 volts with the fsb at 149. How much higher can I go on the voltage before it is hitting the danger zpne? Is 2 volts too high? I have an SK-800 with a Thermaltake Smartfan II mounted on it so my cooling is pretty descent for air cooling. If you need to know anything else about my rig it is in my sig. Also, can any of you point me to a link or two to unlock this chip? My Appogee doesnt allow for the multi to be changed.
