Story of a fried i5 2500k. Ouch!

I had overclock my cpu to 4.6ghz at 1.48v running extend stress test and was happy with the result though I was warned about the high vcore. Then I upgrade my graphic to the sapphire vapor x 280x and there was no display but there was display from the igp. So I thought my mobo is bad and get a new higher end mobo. Still no display! I have tried almost every idea I can find on the net until someone who look at cpu was able to point out signs of a fried and dying chip.
I had overclock my cpu to 4.6ghz and recently been running extended stress test with Ibt which put the vcore at 1.49. That probably fried my chip. As I hD bought another z77 mobo I decided to get a i5 3570k. Install the cpu and everything works out fine. This time round I was conservative with overclocking. At default the chip was idling at 0.89v and 1.07v when loaded running prime 95. I then increase the multi in bios to 40, leaving all else on default. The vcore went up to a max of 1.141v with temp at 56C.
My feeling is this time round I got a good chip and a higher end mobo does help.

  1. The 2500k is actually a pretty good overclocker. Just got to be careful of the settings of your OC. And yes a motherboard that is good quality helps a lot XD

    I was able to overclock my i7-3770K to 5.0 GHz with only 1.4 V and got 10.20 Cinebench R11.5 points: http://www.youtube.com/watch?v=DUoZDjGM9LM!

    Btw, I used the CPU at 5.0 GHz for 6 months and didn't have a single issue, but I decided to put the clocks back to their stock values, because I did not find a point at keeping it overclocked.

    this happened to me once; I cleaned the pins of the chip being careful with static electricity and it worked! try it.

    Too late. Like I said I had bought a 3570k to replace my 2500k. And I don't feel confident of putting it back into the system and definitely would not want to sell it to a unsuspecting buyer ! I will try to figure out how upload a pic of my burnt chip later
