What makes you think this cannot similarly be applied to the single ( even after a hardware modification )

Indeed. I am tired of all this BFL and ZTEX and other FPGA junk in the GPU forum.

I won't be buying any FPGA any time soon so might as well move it out of the way for now.

Thanks !

what you got there?

Are you sure that you prefer CursesUI over WebUI+StderrLogger with ANSI coding enabled?

That's strange. I use RG7Miner too and so far (~18 hours of continuous mining on ABCpool) I never got anything that resembles the "sleeping mode" you describe. What pool are you on? Maybe it has something to do with them? Maybe it has something to do with your connection? Is it stable enough? Maybe the pool was under some sort of ddos attack when your boards displayed that error?

[edit] - I managed to replicate your error by turning off the board then turning it back on without stopping the miner. Every share after that was invalid until I stopped and restarted the miner. Maybe there's some sort of power interruptions on the supply line and your board turns off briefly.

I am still running my 5 instances of RG7Miner. I get the HW Error about the nonce that didn't produce a valid hash once in a while, that's clear now. But overnight had had two units fail with (almost) endless loop of HW Errors of this type. The strange thing is that after a while there was on single valid one again, then again lots of errors, then a single valid one again, etc...

Restarting the miner (Ctrl-C, up, enter) gets them going again. Happened a couple of times now. Possibly always on the same 2 Icarus units, but I am not sure yet it's not even been 24h (I have three instances running at 604 minutes now).
