new firmware update posted today one of the changes is increased voltage to 760 This is the fix you all are looking for so I suggest anyone with flaky performance on there C1's do this update. I pushed my voltage up to match the new update and my miner is running even better then it was a 745 volts
both of mine came from the factory at 250/0725. Is the new firmware supposed to be running at 250/0760? Did you modify the frequency as well? What exactly was the problem this solved for you?
Is there a frequency to voltage table somewhere? I can't seem to find anything published on the frequency/voltage pairs.
It also appears that changing the voltage does not change the startup script for cgminer and it still starts with 0725 as the voltage./usr/bin/cgminer --bitmain-dev /dev/bitmain-asic --bitmain-options 115200:32:8:7:200:0782:0725 --bitmain-checkn2diff --bitmain-hwerror --version-file /usr/bin/compile_time --queue 0 --api-listen --default-config /config/cgminer.conf
edit: I guess it changes cgminer.conf and sets the voltage there to 0760. After about 10 minutes, one of my asics x'd out, so I reset it to 0725 for now.
thanks!
