hi. i have some trouble with overclock.
in my original firmware autofreq firmware

Code:

Chain# Frequency(avg) GH/S(ideal) GH/S(RT)
6 634.47 4,550.34 4,570.80
7 634.61 4,551.01 4,495.66
8 612.85 4,400.00 4,387.96
Total 627.31 13,501.36 13,454.41

then i install 650m firmware my chain 6 give a wrong hashrate. over 15k and some chips in chain 5-8kth.

in old autofreq bitmain add some fixes

Code:

Check Chain[J6] ASIC RT error: (asic index start from 1-63)
Check Chain[J7] ASIC RT error: (asic index start from 1-63)
Asic[13]=11336.400000
Check Chain[J8] ASIC RT error: (asic index start from 1-63)
Done check_asic_reg
Chain[5] Chip[62] middle Temp=80
Special fix Chain[5] Chip[62] middle Temp = 85
Chain[5] Chip[32] middle Temp=72
Special fix Chain[5] Chip[32] middle Temp = 69
Done read temp on Chain[5]
Chain[6] Chip[62] middle Temp=81
Special fix Chain[6] Chip[62] middle Temp = 81
Chain[6] Chip[32] middle Temp=72
Special fix Chain[6] Chip[32] middle Temp = 67
Done read temp on Chain[6]
Chain[7] Chip[62] middle Temp=77
Special fix Chain[7] Chip[62] middle Temp = 81
Chain[7] Chip[32] middle Temp=64
Special fix Chain[7] Chip[32] middle Temp = 62
Done read temp on Chain[7]

and all chip work well. and giving at total 13.5th

how can i fix bad chip hesh in fixed firmware or apply special fix chain?
i want to some overclock but i cant...
