Stress Test Scenario

[no_spam_for_me]

Because neither 'System Tuner Pro' nor 'CPU Temperature' are able to determine the CPU Temperature, I have to find another way and I find it and that's what I have done during the hole day

For CPU usage at 100% I use
'StabilityTest (ROOT optional)' => classic test

https://play.google.com/store/apps/details?id=com.into.stability

I determine the values every ~1 second.


First 15 minutes (starting the 'classic test' after ~1/2 minute):

The SoC runs at 4 cores at 1.8GHz for ~14 minutes till it reaches 105°C. Unbelievable!
Then it begins to throttle. But not at 4 cores, no no, only at ONE core to 0.816GHz. Yes, the other 3 cores are at 1.8GHZ... and not all the time the one core throttles to 0.816GHz and not even the same one...


The next both 15 minutes:

During this time the SoC sometimes also throttles at TWO cores but not really often. Here an example:

104  816000  103 1800000  104 1800000  104  816000
104 1800000  104  816000  103 1800000  105 1800000
104  816000  103 1800000  104 1800000  105 1800000
103  816000  102 1800000  103 1800000  105 1800000
103  816000  102 1800000  103 1800000  104 1800000
103  816000  102 1200000  103 1800000  103 1800000
104 1800000  103  816000  102 1800000  103 1800000
104 1800000  103 1800000  104  816000  103 1800000
103  816000  103 1800000  103 1800000  104  816000
105 1800000  105 1800000  105 1800000  106 1800000
103 1800000  104 1800000  104 1800000  105 1800000
103 1800000  102 1800000  101 1800000  103 1800000
103 1800000  104 1800000  105 1800000  103  816000

Post Stress Test cool down (the next 15 minutes (stopped the 'classic test' after ~1/2 minute)):



All done at 106K4...

Good test..

Hold on,the Max cpu frequency is 1.6G right now..If you want the real 1.8G or 1.9G or even 2.0G..I can modify to you

Very Interesting

Be interesting to know whats the watts/amps are doing to the power pack when the device is under the pump.
Especially with a few peripherals plugged in doing there thing and wi-fi etc.

Could you do any other activity on the device while it was pumping out those High numbers.

Cheers

i would like to take that offer but i like to have the 6330 drivers with it......
can you pm me...

It seams to be able to manage multitasking like a charm...

and believe it or not, but at the moment the stress test is running (1.8GHz @ 4 cores) AND I'm watching a video with the stock player
(class10 SD at NTFS and MKV (x264,1080P, 19.1 Mbps))

BTW: without full load these are the values at stock player (after short cool down time)

Well If you have not let the smoke out yet, then it all looks good if not great.

If you would like to build these kernels I will also do a stress test for the first both 15 minutes...

I also thinking about a way to monitoring during graphical i/o (2D / 3D)... maybe I will find a way...

When I came home today I found that the R89 was extremely hot. All 4 cores was at 100% and CPU frequency 1.8GHz for no apparant reason.

I did record it with my phone:
http://youtu.be/AquX-4aP89g

This "unwanted" stress test could have been going on for upto 16 hours and still all 4 cores at 100% at 1.8GHz.

That is an excellent result.

Good thing those holes were added.
