Now I am curious about i7 and temps but more curious how actual seti crunchers are letting their machines run. I find posts on the net of people running at 100C and claiming no errors but that seems crazy to me. Right now with my overclock to 3.8 with HT off I run around 53C but with HT on I hit 68C which scares me. Everyone on the OC boards seem to think these temps are fine...

Mine sits between 54-59 deg C. According to a couple websites they should be fine at anything less than 75-80 deg so you should be fine.

You speak about Core or CPU temp?


Max. CPU temp for Core i7 920 -> 67.9 °C
[http://processorfinder.intel.com/details.aspx?sSpec=SLBCH]
[http://processorfinder.intel.com/details.aspx?sSpec=SLBEJ]

So I wouldn't go higher than ~ 58 °C CPU temp if 24/7 crunching.


Or, Core temp..
You have the prog CoreTemp?
If you would stay around Delta to TjMax. ~ 20 °C it would be also well.



BTW.
Just curious.
If you have all stock, no OC - which is the CPU speed without HT ?
With HT -> 2.67 GHz
Without HT -> ?

---

My i7 920 HT on not Oced runs at 57°C with the 4 cores running at 77°c each.
The 3 GPU's run at around 80°c.
This is a 24/7 cruncher.

Here are mine in F (ballpark of 72C - perhaps running a little hot):

---

Thanks, looks like I am in a decent range, these chips seem to handle heat as well as they overclock. Best overclocking chip I have ever had.

My i7 is the 2.8ghz one. It is in a dell studio 8000 so i would assume it has a completely stock fan/heatsink. I use the program speedfan to see temps and it says the core 0/1/2 etc. are all at 55deg. cel.

---

Running at 2.67 GHz, not overclocked.
Temps change,so took screen shots in Celcius and F.

Note: The heatsink/fan is a CoolerMaster V8

78C with standard cooler
Another one 80C with extra cooler and oc to 3GHz.
Close to 90 on my notebook.
All at around 20C ambient.

Now I am curious about i7 and temps but more curious how actual seti crunchers are letting their machines run.

What does the Intel specification say for your particular i7 model?

I looked all over intels site but couldn't find it. I don't think I am technical enough. Thats why I decided to go with real life machines that are actually doing the same things my machine would be doing. I've seen 100C and even 115C that people claim to have gotten from intels site but I couldn't find it. Then they have different measurements for different spots on it or something....just thought real life was better and I am adventurous, as long as I'm close to others I will go ahead. The way I mess with seti you should be able to imagine what I put this machine thru and so far rock solid hasn't skipped a beat!

Trouble is, what people do and what they should do aren't always the same.

I found this page on the i7-920, and it says 67.9 degrees C is the maximum for that particular model.

I found it by googling "intel i7 thermal."

While I appreciate your pointing out that someone has their own ideas on this subject, I'm not particularly interested in someone else's opinion.

The manufacturer (Intel) has done the work in the lab, and they publish specifications. If you exceed those specifications, you are inherently in a state of sin.

You may do what you wish.

Hiamps asked "what is the maximum temperature" and Intel publishes their recommended maximums. If he's running hotter, and he knows that, he can choose to take the risk, or he can add cooling.

One can't make an informed decision without information.

My i7-975 "notebook" crunchies 24/7 at 93 degrees C - 201F.

I have a PIII-M "notebook" that has been cruching 24/7 for over 8 years that runs in the same temp range.

Both rigs are stock OEM notebooks (with no extra fans) and temps measured with SpeedFan and CPUID HWM Pro.

Hey guys, I thought I wrote about CPU and Core temps..
I read a lot about this CPU & Core temp stuff..

AFAIK, Intel say officially only the max. CPU temp. (I posted the URLs of both 920 steppings)
Nothing about max. CPU-Core temp.

The CPU-Core temp isn't a real temp.
This is a value of calculation from the TjMax. temp.

If you would stay ~ 10 °C under the max. CPU temp which Intel say, then you would be well for 24/7 crunching. From what I read and do.

I read a lot about the Delta to TjMax. temp stuff (because I have since some years a QX6700, one of few first in Germany ) and AFAIK, if you are ~ 20 °C - it would be also well.
This is an option (enable in the settings) in CoreTemp.
I take WB's example..
CoreTemp say: TjMax. = 100 °C (for the 920)
Detected temp of the CPU-Cores = 65 - 68 °C
So Delta to TjMax. is 35 - 32 °C.
> than 'my' recommend ~ 20 °C. So he run very well.


This is from what I read and I do with my equipment.
If you agree - O.K., if not - it's not my hardware..
(Sure you can go higher with the temps, if stock you could be stable but the life will be shorter. If you OC, you get earlier an unstable system.)


BTW.
hiamps, I'm little curious about the stock CPU speed if HT off at a/your Core i7.
You have experiences about this and your 920 @ stock speed & HT off?
If no, maybe others which have a Core i7 could post their CPU model and GHz speeds (with)/without HT?

---

Well Ned I guess I can go higher than I thought. According to RealTemp at 66C I have 34C before I reach TJ max. So I guess I have nothing to worry about and I have a great overclock....Now I am still interested in how hot other i7's are running seti.

I will have to read up on how to save my bios so I can set it back, changed way too many things that I know nothing about...(ducking from Ned)

Ohh.. then better not to do it..

Normally (in my BIOSs) in the (1st) overview should be a point like SAVE & EXIT .
[EDIT: Maybe you have the possibility for to save one or two user settings.]


BTW.
You have the possibility of reading CPU and Core temp simultaneously?
So we could compare the CPU and Delta temp of the Cores (and 'my' recommended > ~ 10 °C CPU / > ~ 20 °C Core)
