At 6.12G difficulty, is the Chili miner still making money on electricity, at say $0.13 / kWhr?

Yeah, it won't be until after 10B that you might want to tune it down. I should post up another FW here that limits the voltage to ~1V to get the power consumption down to the 130W range at the expense of a few GH/s. It's probably actually more profitable, and would extend profitability (@$450) for $0.13/kWh out to about 18B. I'll do that tonight for you guys.

A little late, but technically I haven't slept yet, so it's still tonight.

I just did a test with four random units, and I'm getting 119GH/s with 483W draw at the wall on 120V. HW error rates also look pretty nice, at 0.1%
I've updated the second post.

Hi Mr Teal
Will this cause a problem for the devices from Lucko, that were set up with the "SLOW RISE" software?

Any change in temp?

I fix broken miners. And make holes in teeth :-)

Thanks Mr. Teal. I'm about to start bringing down the speed of my 60gh Singles, probably in the next month or two. By shorting out the trimmer capacitors on the fluctuation line I have found that I can drop the voltage to the chips from 1.018 down to about .9 or so. Which will cause a Single to fail at speed 7 but will allow hashing at about 45gh at speed 1. The difference in power and heat though is very. very. substantial, should allow a few months more mining.

Shorting the middle pins just resets the MCU. The four LED code indicates that the main 1V power supply for the ASICs has had a failure or an issue turning on. When you say it would eventually go sick and go dead, how long is eventually?

It would mine for about 15 minutes then go sick. Another 10-15 minutes later it would go dead.

And thanks for the response.

Evening all, but specifically MrTeal. I've got a little problem with a chili and was hoping you (or anyone in this thread) had an idea.

I recently purchased a Chili that would mine at first but would eventually get sick and finally go dead (as reported by bfgminer). I did have to flash the miner when I first received it but that didnt help. This morning after it died again I powered it down, waited 30 seconds, powered it back up but now Windows wont see the device and LED's 5-8 are all stuck on. I've moved the miner to another machine and it does the same thing.

In reading this thread I found that MrTeal mentioned something to another user about shorting the two middle pins on the "prog" connector so I tried that. When I do that the LED's go out and windows see the com port device. When I remove the jumper windows no longer sees it.

Any thoughts?

Thanks for your time.

Was it a single Windows Update or several? What was it an update for? If it was only one update, I'd probably try uninstalling that single update to see if that made things work again. As much as I don't like this option, a System Restore to sometime last week might be worth trying too.

None of the above would explain why it won't work on multiple PCs but I'm using 2 Chilis on a Windows 7 x64 PC without any issues. One thing I'll say though is that I actually disabled auto-updates because I didn't want it restarting in the middle of the night and losing hashing time. I just check for and install them manually once a week or so but its a very bare bones PC with little more than mining software on it.

It was just one update - Dev is helping me too, Thank you so much Dev. I tried a system restore to last week, it didnt work sadly. I tried removing all the updates, I tried removing the driving currently on the miner, ive tried plugging the miner into another computer and even there it doesn't have the original normal information that it used to, that's what I don't understand. It acts normal but none of the normal information is there when you plug it in. When you try to program it with Chili flash on either computer, it doesn't show up on any USB port, so it won't let me reprogram it. Its frustrating because I know the computer notices it, it says "Downloading driver for new item plugged in" which always fails to download of course. then it just says unknown device and thats it. or "USB Composite device". It doesn't register as a ASIC Miner anymore.

If your room temperature is to high, then the power circuit may not be resetting.

If that is the case then try to get the chili temperature below 20c and try again.

I had a month ago a something similar issue, Tried first reinstalling FTDI drivers but solved replacing 4 port USB Hub connected to Chilli boards. But I use windows server 2008 so maybe is not same problem

Ok I went ahead and set the updates on manual so it won't do this again to me. I have tried something new that the Dev told me to do - he said to DL the FT_Prog and try to locate the device and install the driver there. No device was found - So he told me that points to a hardware issue :/ Gosh I hope I get this fixed. This might of just turned into a very expensive desk ornament/paperweight :/ Fuck me. When it rains it pours.

I have too one what has exact that error (one of Lucko ones) but it seems a chip is gone not a real board hardware issue. Lucko will fix it for me as this broken chip should cost not as much (about 10 USD or so).

Windows auto update often screws up the PC.
Set it to manual so that you can review and install when it's convenient for you, not microsoft.
