I'm less concerned about a well-established outfit with a several-years business record not sharing its tax ID than I am with it refuting the claim to be a distributor. He left it open that maybe they were a distributor and he just hadn't heard about it, but why is that potential huge lie less of a concern than whether or not BitmainWarranty/Myrig is real?

What am I missing?

Yes that's normal because you're using the wrong software. Read the first post. There's no reason to expect a version of cgminer two years older than this stickminer would support this stickminer.

The fix is figure out which chip is hosed and replace it. Generally a manufacturer warranty thing. If you bought from a reseller who's not a low-down dirty deceiver he'll probably take care of you.

Ah, so you would fall under the "only if your hub sucks" clause wherein powering on the second stick causes a bit of a voltage sag and something trips.

That's the kind of thing I'd expect someone who knows as much as you seem to to have figured out on his own in about five minutes.

You're not thinking the S9, are you?

You sure it's not reading from the SO-8 TMP75 in the center of the board using I2C via the TSCL and TSDA lines on the cable connector?

Dang, where was this a year ago?

Only if your hub sucks.

The zombie issue happens more frequently when your ratio of speed to volts is too high. As VH says in the first post, in the troubleshooting section, about Zombies - either increase voltage or reduce speed.

Wow, all the numbers y'all are throwing around make me glad to be self-sufficient.

$8k just to surface-mount pipe in some new outlets from an existing panel? Sounds about like a one-day job, so no more than a hundred bucks plus materials. That bid is almost twice what it cost me to do a 400A three-phase upgrade to my shop, including the panel and breakers, new pulls to the pole and the hosting room and new per-shelf subpanels.

You also need to consider not just the wiring, but the junctions. Solid wire can handle a lot more power than a bad junction. And since outlets are daisy-chained where power to the final outlet on the loop goes through every outlet inbetween, there's a lot of potential failure points. If you have to use 110V outlets on 14AWG wire, please use the first one in the chain.

Testing in the last week, latest Minera would run at most about 6 hours before locking up the Pi and dying. The Raspbian Lite setup is at 3 days 16 hours uptime without blinking.

I mean, the miner's blinky lights have been blinking quite a bit. Because the Pi is running steadily. USB traffic should be about equivalent to four 2Pacs at 250MHz, or ten stock sticks.

Dang, if only the first post had a Troubleshooting section with a bullet point about Zombies...

It's fine if you didn't read all 78 pages. But nobody should ever post an issue here without having first read Page 1.

If it's a DPS-800 or an HP Common Slot, my board will work with it. I've tested them on HP-CS from 750W to 1500W.

Cables are no problem.

I could conjure up a few of those on short order. Not a lot, but I've got some on a shelf somewhere.

No, I haven't worked with that supply in some years. I'd check with Optimizer.

I'm cooking up a fresh batch of my Dell 750W boards in a few weeks. Two of those will load-balance to put up 1500W from 120V for a hundred bucks.

So it always reads low on the one chip, even after plugging it in with a good high voltage (1.4 or so) across both?

I'd try increasing the voltage a little bit. How to do so is referenced in the first post.

Bitshopper should get a shipment by the end of next week, so he may list stock again.

I now have an official sales rep, so as soon as I have general stock I'll re-open sales with some stock queued for small direct sales. Probably 90% of them will still go to resellers, but there will be a weekly reservation just for small orders.

Strange. I've not used either of those power supplies, but my whole shop is wired up on 208V (from a three-phase wye) and I've never not had a PSU work. At least six different server supplies and four different ATX supplies and three versions of Bitmain's PSUs all work just fine.
