Well, today my 2100 AIUHB arrived, and also today.....It died. Thats right, I have just killed this brand new chip in under 12 hours flat. I still havent a clue as to why the chip fried. I was burning in at 2406mhz, 2.0v, and just chatting on MSN, then all of a sudden i get this horrid screaming noise in my speakers, and my computer locks up. 5 seconds later I smelt that evil smell of a burnt core. Immediatly my heart fell into my shoes as I knew i had just toasted the thing. Why on earth it just all of a sudden blew like that I dont know. Was almost like a light bulb, just running fine for hours then POP. So, Im in the dumps pretty bad right now. Im going to reorder another one tommarow and this time take it much easier on it. I think ill keep the voltage at 1.85v and under to stay safe. Either the chip didnt like the 2.0v or the temperatures, which according to the surface temperature wasnt but 39c. My cpu Core temperature was pushing 68c though, and I think that was my problem. That is very odd to me though to have my motherboard diode report 39c and the core be at 68c. Either way, Ill definantly be taking it easier next time. Let this be a caution to all you guys out there pushing your voltage to 2 and higher, as you could just end up with a dead chip all of a sudden. Why Mine decided to go so quikly I dont know, Ive seen guys with worse cooling than me pushing 2v on the Vcore and it seems to run fine. Maybe I just got a faulty chip, dunno. There goes $100 for about 5 hours of overclocking fun....lol. Atleast i didnt damage my brand new motherboard in the process.
