Beat you to it
Much different method though... keeping a special sensor on the back cool allows the device to dynamically open up the PL1 value up to 25 watts continuously. This special control that the SP4 has over PL1 via hardware might affect any special BIOS adjustments... what do you think?
I don't like having a fan either, that's why I'm asking, is this method really working?
I think you need to do what the OP said, follow all that procedure to modify the firmware and then "for disabling Package power limit lock, type: setup_var 0x27 0x0". But I haven't tried. Anyone else tried?This method is not working for me. I have played with both XTU and Throttlestop. I can control the thermal TDP by limiting the clock boost, but the 4650U has some sort of TDP power limit (as opposed to the thermal limit). When I play borderlands (CPU+GPU), the system draws more than some amount of average TDP power and the system throttles down the performance.
In throttlestop the TDP level 1 and 2 are hard coded at 11 and 25W, respectively. I can't seem to change this value. But I think this is the source of the performance issues in my SP3. Has anyone figured out a way to modify these 2 values?
Where can I download the file from the first message?
I have the same issue with TDP throttling with my SP3...
Thanks
