Things are more complicated though if you read through the 2nd link.
»www.tomshardware.co.uk/intel-dts···460.html

I found the info in this ongoing thread.
»forums.anandtech.com/messageview···thread=y

I also have a Q6600 GO with a VID of 1.325 and have it OC'd to 3GHz with stock voltage. My cooler is a Xigmatek S1283 which gives me idle temps of 36,35,30,34 and load temps of around 54C when using an unmodified Core Temp 0.99.2. Ambient is around 72F.

I also have calibrated Speedfan and Realtemp (not TJMax) and they seem to agree with the lower numbers that Core Temp shows. I'm sure things will change once the temperature monitoring programs decide what to do with the new TJ Max numbers.

Mr.DKS.....I RESPECTFULLY disagree with all 3 of your conclusions, please consider the following information.

Said by DKS...I would be very surprised if you were running at 100% load without thermal throttling at that speed.
-I have several friends who run at 3.6 for 24/7 without thermal throttling. Although I cannot reach that clock, I have 3 machines running 24/7 FULL LOAD between 3.3 to 3.4ghz for periods of 1 to 10 months.
Um... no, I'm not wrong. you won't see thermal throttling because the chip temp isn't 100c. The load raises the chip temp too 10C, which induces thermal throttling.

Said by DKS...You can't tell if thermal throttling is in play unless you run the Everest stress test, though.
-Indeed you can spot thermal throttling with almost any distributed computing program. Easy to spot when the "time to completion clock" begins to stall out. ONLY 1 out of 3 of my machines will thermal throttle at anything over 3.3ghz. The other 2 machines will just shut-down in rejection of a too-high overclock.
Again, thermally induced throttling is irrelevant to the overclock. It is related to load and cooling. Remember, it's thermal overclock.

Said by DKS...But you can't turn off thermal throttling, I don't think. It hits 99C and it's automatic.
-I agree that thermal throttling is probably some internal chip function, but no way do I think it is related to 99 degrees centigrade. Did everest say that? My one machine that thermal throttles does so at the same 48-50c. At least according to speedfan, which is relative to compare these 3 machines.
Yes, it's related to the temperature of the chip. And yes, Everest tells you that in the chip specs. It's called Tjunction Maximum and it's 100C.

For an excellent discussion of chip temps and what Intel's specs are for the Q6000 series, see here: »download.intel.com/design/proces···5594.pdf

You also asked about cooling, so here are some facts...
1-Q6600@3.0-asus with tuniq tower for 6 months 24/7, max temp 50c.
2-Q6600@3.4-gigabyte with artic freezer7 for 10 months 24/7, max temp 54c.
3-Q6600@3.33-gigabyte with tuniq tower for 6 weeks 24/7, max temp 50c.
Ambient is a constant 73-76F. All 3 cases are the same.
You have good cooling. I'm not sure of your point. All I'm saying is that thermal throttling can be seen when proc temps exceed 100C. Which is the Intel spec.

It certainly makes sense that thermal throttle "SHOULD" initiate at a certain temperature; however,"ONLY" machine 1 will thermal throttle at anything over 3.3ghz and NOT at a higher temp.

In conclusion, I'm thinking that it must be batch number related? I cannot provide the batch number because I only recorded 1, possibly 2, and don't remember which is which.

Sorry for the hi-jack, but just my 2 cents worth, hope it helps :)
I disagree. It is related to proc temp (Tjunction Max). You can change any parameter you want and as long as you don't hit Tjunction Max of 100C, you won't see evidence of thermal throttling.

I think you should be running it at a lower rate or get better cooling.

I was able to get Everest to run finally from a live cd, and I get no CPU throttling nor do my temps get anywhere near 100.

Oh btw, the VID on this CPU is 1.25v. Which makes it an even bigger mystery why the CPU is unstable at any FSB greater than 356.

So does it query the same sensors that Core Temp does? It seems rather odd that your temps are nearly 50 C higher than mine. What is your ambient temperature and what are you currently running the chip at? I think I remember you are using a stock HSF, right?
