Thanks for testing.  Can you be sure the 2201 Mhz setting works
properly.  Perhaps you can set dev.cpu.0.freq=2201 then 1600 and be sure
it has approximately correct CPU performance.  One test I use is:

  dd if=/dev/zero bs=128k count=N | sha256

where "N" is some number that takes about 10 seconds to complete.
