TBH my primary goal was to have stable SR for stock frequencies, as those who OC usually are aware of what's "under the hood". So far this seems achieved and I am happy .
Well, seems there is no option left, but to export sysfs entry for MPU similar to sr_dsp_boost, so on devices like yours a liitle voltage boost to be given to MPU for OC frequencies. But that will be in the next release.
