Actually, my Haswell-E still boosts to its overclocked speed just fine at 4300. The issue is that PMDrvr.kext is unstable for the system. When I enable EIST and use PMDrvr.kext, I get the best geekbench scores as I believe that enables the cores to throttle up and down far more responsively to load. However it causes the system to crash under load in Adobe CC 2018, especially Premiere Pro and After Effects. This is despite its stability in Prime95. My guess is that the voltage movement isn't as responsive at sometimes the CPU gets caught in a moment of high speed but unsuitably low voltage that then causes it to hang. This behavior occurs even at stock speeds, so I believe my conjecture is likely right. Without PMDrvr and EIST, my geekbench scores are significantly lower. So I'd rather force it to run full throttle all the time to get the desired score and performance. The chip is sufficiently cooled, so there are no concerns there. Please PM me if you have a solution that you don't wish to publish publicly.
