I'm on Viper, and no matter what I choose in Kernel Tuner or the ViperXL Tweaks, both cores are always on. When I'm in the Kernel Tuner app and press the button to turn the second core off and then check the Viper Tweaks, it still shows it as being on. If I switch it to only one core in there, and then go back, it's switched back to two cores. I wanted to try with just using one core because I think using both may be why my phone gets so hot.
Also, the setting of the frequency on the second core doesn't stick. It always stays at 2.1 and 192. If I set the max lower when I go back into the menu its right back to 2.1ghz.
