Underclocked S1 (Pencil Mod)

[deathlordz]

Hey guys!!

 I recently underclocked my antminer S1 (pencil mod) for various reasons and I am getting some unexpected results. The miner is running around 100 GH/S with an error rate above 20%  and I am not quite sure why. I figured I would be able to run this bad boy around 140 GH/S with an acceptable error rate and I still believe it is very much possible(I must be overlooking something). Any and all suggestions are welcomed, below are the settings and adjustments I made.

Board One:
R3: 2.96 R66: 2.89 R38:2.95 R52: 2.93

Board Two:
R3: 3.01 R66: 2.91 R38:2.95 R52: 2.99

option 'freq_value' '0A81' #275M
option 'chip_freq' '275'
option 'timeout' '45'

I made some edits to the asic-freq file and got some better results  .

        option 'freq_value'     '0881'  #225M
        option 'chip_freq'      '225'
        option 'timeout'        '55'

Gives me around 120 GH/S with an error rate <1%.
