Temperature goes way above the set limit [SOLVED]

[jean]

Hi Tthrottle users.

I'm encountering a small problem.

I installed Tthrottle and it seems to be working fine : the graphics show the temperature increasing, etc.

I have also checked "Auto Active" .

However it doesn't seem to control the temperature: I've run Minecraft (which is a Java application that uses hardware-acceleration 3D libraries) and I see the temperature go way above the 80°C that I set up: it went around 110 degrees, and eventually crashed the computer. The same happened at every attempt.

It's not caused by the GPU-greedy piece of software itself, because I also tried with another specialized tool ("OCCT"), that is supposed to monitor the temperature AND run tests on your GPU and CPU to see if they are faulty. OCCT has a reputation of being good at preventing your GPU from frying during its stress tests. Yet, the temperature went around 110°C, and then the computer crashed and rebooted.

Did I gorget something? Is it an incompatibility with my hardware?
I've tried disableing the "smart fan" in the BIOS -- after that the fan rotates full speed and my computer sounds like it's going to take off. That slows down the temperature rise, but it always eventually reaches the critical point where the computer crashes.

So, what's going on? Is there another setting in TThrottle that I didn't see? Some subtle feature? (e.g. Tjunction temperature).

For the record: I have an Acer Aspire M5810 (exact model: FF7R), which contains a GeForce GT 220 and an Intel Core i5-750. There is only 2GB RAM.

[jean]

Forget all of the above.

There was just about 3 tons of dust in the GPU's fan... That's why the temperature was skyrocketting AND Tthrottle was unable to keep the temperature down (the fan was probably rotating at 100% speed permanently).

Sorry for polluting  the forum and thanks for your great soft!

Okay, I'm having a similar problem, and my laptop is brand new (i.e. no accumulation of dust in fan).  seti@home responds correctly to Tthrottle and ratchets back CPU usage as temperature goes up, but climateprediction.net completely IGNORES Tthrottle and runs at 100% on all the cores it is using.  (seti@home winds up shutting down almost completely, since the overamped climateprediction.net cores are heating everything up.)  I can't figure out a way to set a CPU usage maximum on climateprediction.net only without affecting other projects.

Windows 7 Ultimate x64
Intel Core i7-2760QM (four cores, two threads per core)
8GB RAM
NVIDIA NVS 4200M
Tthrottle 6.31
BOINC 7.0.28 (x86)

"Connect with BOINC client" is checked, no rules, CPU core set to 75C max.  Help!

When climateprediction.net is running, copy everything in the Programs tab: Number of matching Programs (Processes)
Maybe that shows why.

Most likely a wrapper, a program that start some other programs.

I see what you mean; it looks like the "XXX:" entries are the wrappers, that in turn spawn the "Child:" processes.  How do I rein these suckers in?

I will attach to the program and see if I can get the same kind of work.

The XXX means they are doing nothing at all, they only start the Child program.

Do you have "Auto active" checked?
What is in "Running Cpu" ?

Did you check what tasks are using the CPU.

[fred]

Can you try this:

Copy from C:\Program Files\eFMer\TThrottle\examples tthrottle.xml
into the folder C:\Program Files\eFMer\TThrottle.

Search for the <exclude>

And add/replace :

<exclude>
  <percentage>0</percentage>
  <debug>1</debug>
</exclude>

Restart TThrottle.

Still no work.....

[tkelley]

It's suddenly started behaving properly, before trying these things.  I'll keep an eye on it and do this if and when it starts misbehaving again.  Thank you so much for your great help and quick responses!

[tkelley]

Okay, it's misbehaving again. 

"Do you have "Auto active" checked?"  Yes!

"What is in "Running Cpu" ?" 
2% (when I scroll over the task tray icon, TThrottle says, "Temperature CPU: 85C - Run CPU: 2%  Temperature GPU: 62C - Run GPU: 1%"

"Did you check what tasks are using the CPU."
Yes, in Windows Task Manager, I can see hadcm3n_um_6.07_windows_intelx86 using 13% of total CPU capacity.  This is one entire thread (2 threads x 4 processors), running full out.  The SETI processes are all using less than 1% of total CPU due to the elevated temperatures caused by the runaway climate prediction process. 

Interestingly, now the XXX: entries are gone.  Here's how the processes look now:

Number of matching Programs (Processes): 9

Now I'll try the <exclude> thing.

[tkelley]

Okay, I put the edited tthrottle.xml file in the directory you specified, with the <exclude> language in it.  climate prediction is still running full out, 12.5% of total CPU, and all the SETI processes are ratcheting down to compensate.  In other words, no change.

One other thing to note:  the climate prediction process is flagged as "high priority" in BOINC.  This shouldn't matter, though, should it?  I can't imagine TThrottle would care.  And I think some other climate prediction processes that weren't "high priority" still behaved like this (though I can't be sure).

I have one task running on my machine

XXX: 0 (0%) - PID:1932 (3)   Slot:10   http://climateprediction.net/   hadam3p_pnw_q8vw_2043_1_008358811

climateprediction.net   6.09 UK Met Office HADAM3P Pacific North West   hadam3p_pnw_q8vw_2043_1_008358811_0

It throttles back nicely I can see a CPU load of 30% in BoincTasks.  It runs a load similar to Seti.

CPU:1 (-1%) Strange, not what it should be, something is not right.
So with -1% things don't work properly.

Can you exit and restart TThrottle and give me the everything (the text) in the Log tab.

[tkelley]

So far so good!  I'll post again if it goes off the rails.  Thanks for your help!
