Hey just a quick one - I feel I am missing something here. Maybe someone can enlighten me.

I have an S3 B1, running the following...
antMiner_S320140826.bin
cgminer 4.6

Load is nice and low - but the hash rate seemed to be below what I am seeing on other S3's  - so I was trying to push it a bit beyond to see if I could 'encourage' a few extra GH/s from it.

So SSH'd in and added the following -

option  'freq_value'    '1406'     #256.25M
option  'chip_freq'     '256.25'
option  'timeout'       '15

:wq -> reboot - but it is still showing as 250 in the gui - can anyone confirm if the new 'Advanced Settings' tab under 'Miner configuration' will over ride the manual entries I made in the asic-freq file?

Also - while I am at it...

I have such wide variance in the hashrate of the S3's anyone any suggestions on coaxing the slower ones towards 500. 2 of them are consistently at 505+ but some just seem determined to go slower - like sub 440 and even down as far as 400. Have tried playing around with freq's and FW and different PSU's etc. Has anybody had any solid results with checking/re-applying the thermal paste or even just re-seating the heat sinks, as I have not gone down this road yet?
Thanks
