in my tests, 0780 & 4f81 yielded the same result - so I think they are both very close, if not 400mhz
I can confirm that my overnight test seems to be a success... averaging 197GH @ .59% HW ... which is higher than the 375mhz setting, but lower than 400mhz
I dont know what the exact equation is for figuring out hashrate based on clock but the numbers match up with 512*mhz = mh/s
Based on that equation, 5e82 seems to clock in right around 384mhz
Also, if someone wants to experiment w/ the xx83 ranges ... I imagine the values will start in the 6x83...
I now figure out the HEX.
400MHz = 0780, = 4F81 and also = 5F82, but 0780 and 4F81 are preferable,
as it comes with the config and don't know whether 5F82 will do any harm.
387.5 MHz = 4F01 and also = 5E82, you may try 4F01, it should be OK (may give different HW error, but same MHz)
So I tried something like 412.5 MHz '5001', and again very high HW errors 4.x% (~ 425MHz's HW error).
I think I have good-enough cooling, it might be the hardware stuff for the error, so I went back to 400MHz then.
Did u just figure out those particular ones or do you know what the actual "pattern/equation" is?
