thanks. Your MSR_CORE_PERF_LIMIT_REASONS seems to indicate that the pcode is clipping you after the microcode update. But just to be extra sure it's not a software problem, can you please update the microcode and do this:

# turbostat --msr 0x199

And paste the output.

One last paranoid check is to install the microcode directly from the intel site, just to make sure there's nothing wrong with the packaging.
