Yeah but, unfortunately, it does not surprise me. I had to rma my first 6700k as well and it overclocked better than the one I received. (The new one does work though, I will give you that.)

+JNavy89GT - What temps do you get with your stress testing please?

I have never killed a CPU so I never knew what the symptoms were. I have killed everything else though....

Glad that he figured it out.

And for the record, I WAS WRONG.
 
I think I've only had 2 prior to this and that was probably 200-300 cpus of samples. Well, that is go bad for reasons other than chipping corners of duron/atlon, heatsink popping off and frying cpu(before thermal shutdown safety) etc...
 
temps on the Asrock were good. load temps with case off were 50's C, and with case on high 60's C with the i3. The i5 only ran for a few posts/boots prior to fail and I don't remember temps really other than they seemed fine. With the Gigabyte board, the temps are higher. Much higher. I think the boards are just different in calibration though, so I'm not sure which was right. I'm getting 70-80's C load temps now with the 6600k. I am going to get a Corsair AIO cooler to see if that helps. If not, then it's either the board reads high, or my chip has a crappy TIM between cpu and plate.
 
Man, be careful with that. I had an ASRock 1150 ITX board, can't remember the model. I used it with a Xeon initially for an ITX build and it did the same thing you were describing. Booted fine a few times and then it would turn on/spin fans with nothing else. I tried an i5 in it from the local Fry's, and after two boot cycles it did the same thing. The board itself was bad, and ended up killing two CPU's, two sticks of RAM, a GPU and an SSD. I would hesitate to use any boards of any brand that were involved with multiple bad CPU's. If this were my situation I would return all of it and start fresh. Good luck.

Well, with the new 6700k replacement I received, the load temps are 80C running IBT at stock settings. However, if I set VCore to 1.28 and LLC to High, it runs at a load of 62C which tells me there is something funky with the mainboard firmware. Also, I can do an Asus suite burning test and a IBT test at 4.5GHz and 1.32V, LLC High and it never crashes. However, P95 almost instantly fails well it does not fail at the stock settings with manual vcore and llc set. Something tells me there is some other setting or settings that need to be played with because even at 1.35v, P95 still fails. (Could be that I am on a pre P95 firmware fix but, I am probably not going to bother with P95 anymore.)

That's not what it tells you. IBT runs CPUs at unrealistic workloads which generate more heat than you'd ever see in the real world. Intel Burn In Test can be used for stress testing, but is in no way indicative of how your CPU will actually behave when oeverclocked. Prime95 1.28 and newer have issues with stability on the Skylake / Z170 platform. You need to update the BIOS and go to the latest Prime95 version if you want to use it.

Nah, I was referring more to the fact that the mainboard is running the cpu is higher than needed settings at stock with everything on auto. That did not happen with the first 6700k although it had a bad memory controller where this one works as it should otherwise. Thank you though for the comment.
 
I wonder where are all the guys (real technicians) that keep insisting on replacing PSU huh. Glad You got everything figured out, JNavy89GT.

I killed a Q9450 by droping a screw driver on the motherboard, blew a mosfet and killed the cpu. Also received a DOA brand new out of the box athlon 64 3000+ clawhammer.

Ah, death by screw driver, have not done that in a while. :D
