Have you been able, or even looked into, what Bitmain did to limit speeds on the Z11e and Z11j?  I have had all three, and from what I can tell, there are the same number of chips, boards, and power, but they somehow throttle the Z11J and Z11e.  I have used eFudds firmware on them before and I can increase the frequency and squeeze a bit more out of them, but only at their throttled speeds.  Ideally, I would like to turn the Z11e into a Z11.  

I am not someone who can really dig into this, but if it is software limited (Or on the chip somehow?) I would certainly pay to be able to turn a 75k sol/s Z1e into a 135k Z11...

Thoughts?
