Just bitmain, after getting scammed by syan and almost by a few others, I find it hard to trust anyone. I took a chance with lightfoot and he is a straight up guy, but has no chips to help me get my board going.

Bitmain offered no inside USA help, even after I offered to pay for the repair, they still wanted me to ship the whole unit back to China

Bitmain was requiring me to send the whole miner to China and other people claim it takes at least 8 weeks to get it back,  plus the chip is bad because of my own fault and really shouldn't be under warranty.
Like I said before, I would be more than happy to pay you $100 for a working chip if you want to scrap your board so I don't have to. Its not gouging when people are willing to pay it happily.

I have a 2 month old S9 that lost a chip, lightfoot has it and posted a pic of it above, since I cannot get a replacement chip, I am considering paying him to remove the 62 working chips so I can sell them for $100ea. Would there be any interest in this? I know if someone was offering to sell me a working chip for $100, I would jump on it.

Hey lightfoot, my account won't let me send more that 1 pm an hour, please text me on the number I pm'ed you a few weeks ago.  My zip is 74008.
Thanks,
Dave

I have been mining the SHA256 for 3 weeks now. In the past 24 hours I am only getting 21.5 DGB per Terrahash per day. Is that in line with what others are getting?

If it's not dust or high room temp causing the problem then...
My guess is you guys are using 120 volts, switch to 240 volts and you will see less drop in 12v thus never seeing the higher amp draw that causes this.

Is the burn still going? Is that what you are counting down?
