If the cpu needs to be ran below 85c why would intel set the tjmax to 100c?
Remember it is running completely stock

Out of curiosity, why can't you make any BIOS changes?

I can vouch for the Hyper 212. After I've installed it, temps went down to 55c idle and 70c under load (gaming). I'm running the 920 with hyperthreading on and on normal voltages.

People, whatever you think you know about CPU's, you're dead wrong when it comes to the i7-920. It's a beast that can't be tamed. TBH, Intel should have recalled all 920's for this temp flaw.

Sounds like you either got a crappy chip, or weren't using the right amount of TIM.
Not the case with my chip, I just have ambient temps 20c higher than normal, so my cpu temps are also 20c higher than normal...


EDIT:
No bios/ physical changes until thanksgiving when I go home.
I am in lubbock, this computer is in dallas.

EDIT EDIT:
BTW I have stopped folding on the chip for the time being, so everything is fine.
Thanks for the advice everyone

Should I be concerned about this?

You are throttling, and you should not be.

This is a concern.

Are you certain the system is clean, that the cooler is mounted/secured correctly, and that the fan is working as it should?

There is no difference in design between a Xeon and an i7 of the same architecture on the same socket. None. The biggest physical difference implied is the etching on the IHS.

I've owned at least two C0 Bloomfields and nearly a dozen D0s. There is no "temp flaw".

Even the hottest running C0 i7 920 samples will run 24/7, 365, on the stock cooler, at 100% load, and be well within safety limits, unless the builder/user has done something wrong.

You should not fold on it until you sort out why it's running so hot.

Yes, 100C is safe, but it would likely be running hotter if it was not throttling, and despite being "safe" right up to the TJmax, almost no correctly configured system should ever reach this.

Something is clearly wrong somewhere. Unless your closet is over 50C inside, the CPU should not be running as warm as it is.

Figured I'd add one of the cheapest and easiest ways you can shave off 10C easily is to lap your processor. Go to your local auto store and get various grits of sand paper 600 800 1200 1600 2000 and just shave away the crappy nickel plating and expose the copper. I lost 18-24C on my i7-920 across the board and my temperatures became more even across the cores (When viewed in the light my 920 was shaped like a bowl before I did this)

@Blameless, It actually wasn't "throtling" It was just swithching between stock and turbo to maintain 99c on the hotest core
That was my understanding of Xeon vs I7 as well, thanks for confirming
My closet is probably close to 40c, ~100f
this is not in a high airflow enthusiast case, so air temp in the pc is probably even hotter still.

@Dew, I have lapped a processor, I would not describe it was the easiest way to cool down a cpu...

It sounds like it was throttling. If the RealTemp - Thermal Status area shows OK then you're right, it wasn't throttling. It if shows LOG then that confirms that it was throttling. Some software doesn't notify you about throttling until after it has been happening for a while.
