Re: [GUIDE] BitFury Miner Support/Tuning

Okay, i made changes to settings, problem not solved...

And this is what i get...:

speed:2592 noncerate[GH/s]:96.651 (2.014/chip) hashrate[GH/s]:100.665 good:6751 errors:1585 spi-errors:1 mis$
4: 864 30.695 34.045 2144 339 0 1
8: 864 31.897 32.481 2228 849 0 0
C: 864 34.059 34.140 2379 397 1 0

Voltage still 0.3V

I measured resistors,
R01F: 2,120K ohm
R02F: 2,120K ohm

..so Ti chipis broken...?

1) switch to autotuning. clearly setting manual tuning to 54 across every chips is working terribly based on your 15-30% error rates.
2) R02F is quite high at 2.12K(ohm). try using the pencil mod to reduce it to 1.85K(ohm) and see what happens. If lucky, this is the issue and youll see the voltage rise to >0.6V. If it does, maybe the wrong resistor was placed and you should see if it can be changed for something in the 1.65-1.8K range

1. As you can see, m-board don't even detect BANK1 h-card(s). It is autotune mode now, but no help..
2. If I do pencil mod that, that will broke h-card warrantly...?

pencil modding is techincally messing with the warranty, but a tiny marking of pencil lead is not very hard to clean off and, unless you seriously manage to do it wrong, shouldnt cause anything worse then putting a bit too much voltage that in turn turns off the chips until you restart the miner (after dabbing away a fraction of the graphite with a fingertip)

try pulling out and re-inserting the board. i had a board dissapear the other day (after almost a week in place) and pulled it out, checked the connector and reinserted it. works fine again. I think if there is vibration from fans or weight from heatsinks it may be possible it simply isnt seated perfectly with all the connectors making contact.
