Just upgraded my system. Comes with original boxes and and manuals. I had this cpu running at 4.4ghz water cooled. Prime 95 would get it to around 70c, gaming around 60c. The bios is set to the stable OC it has. How ever I would suggest resetting bios. I've had it up to 4.6ghz as a test to see if I won the silicon lottery. But it wasn't stable past 4.5ghz. dropped it to 4.4 for daily use. It works great, if you have a psu and ram you can test it. But there's no need to as it came out of my rig yesterday. I'm sure I have a cooler somewhere if you need a temp one.
