vddobrev: This solution works really well for me! I hope there aren't any issues with doing this but it seems to me like the best solution yet.

Good to hear! You can always play with "i.-4...U\":9000, i.e. if 11000 seems high, you can try 9500. Anything above 9000 will not throttle in tablet/tent/stand.

Hey Vddobrev, could you specify what exactly did you change.
Did you change all those 9000 for 11000 ?

No, only for Haswell U skus, in bold below:

 

Original:

echo "StandardMode\\PackagePowerLimit"="\"i.-3...U\":90​00;\"i7-3...XM\":35000;\"i.-3...Y\":9000;\"i.-4...​U\":9000;\"i7-4...MX\":37000;\"i.-4...Y\":9000;\"2​...U\":9000;\"3...U\":9000;\"2...Y\":9000;\"3...Y\​":9000;9000;" >> "%TEMPFILE2%"

 

Changed:

echo "StandardMode\\PackagePowerLimit"="\"i.-3...U\":90​00;\"i7-3...XM\":35000;\"i.-3...Y\":9000;\"i.-4...​U\":11000;\"i7-4...MX\":37000;\"i.-4...Y\":9000;\"2​...U\":9000;\"3...U\":9000;\"2...Y\":9000;\"3...Y\​":9000;9000;" >> "%TEMPFILE2%"

 

However, you can also give a smaller than 11000 thermal limit, for example:

 

echo "StandardMode\\PackagePowerLimit"="\"i.-3...U\":90​00;\"i7-3...XM\":35000;\"i.-3...Y\":9000;\"i.-4...​U\":9500;\"i7-4...MX\":37000;\"i.-4...Y\":9000;\"2​...U\":9000;\"3...U\":9000;\"2...Y\":9000;\"3...Y\​":9000;9000;" >> "%TEMPFILE2%"

If you know, could you explain how we can tweak this so that we can get some throttling but not as much as Lenovo forced upon us?

 

For example I have DPTF turned off completely and yes the machine does get hot but I need the power so i've accepted it.  Above you said that Lenovo has set this setting to 9000 which others have found to limit the CPU to 25% of output.  You recommend the Intel recommended setting of 11000, yet state "anything above 9000 will not throttle".  Why not just disable it completely then?  I didn't see the difference.

 

Is there a value in this configuration that would allow the CPU to limit some power but not as much as Lenovo's setting?  ie. 9000 = 25% power is too restrictive; 11000 = no restriction, is the same as disabling completely, which gets hot.  Is there a setting for say 75% power?  9200 perhaps???  Is that even a vaild value??

Yes, any value between 9000 and 11000 is valid, you can experiment. I should have said "any value above 9000 does not throttle that much, or throttles less" ;)

Ahhhh gotcha so for sake of stating the obvious 9000 is the crappy OEM throttling which others state is roughly 25% of max power and 11000 would be no throttling (????) and any value in between would be a variaton there of, right?  

 

I think that helps a ton.  Thanks so much  :smileyhappy:

vddobrev- Thanks so much. I reinstalled the DPTF drivers reenabled in the BIOS and set to 10000 to start. Still my high quality videos lagged, then I tried 10700 and they got better but still a little lag. Updated to 11000 and everything ran well. I think even at the 11000 setting there is still some throttling capability but it's not enough to matter since I had to run 3 applications along with the video to see even a little lag. And generally if I'm watching these movies I'm not doing that much else so it really shouldn't interfere.

You are welcome! What bothered me most is that I bought a Yoga 2 13" for my daughter, with an i-3 4030, and it performs much faster in tablet mode than my Yoga 2 Pro with an i-5.

 

That was the reason I digged in to find this solution.

Does anyone know where the KonaDPTF9w.bat file is located for the Yoga 2 Pro?
