Right, but if an *unauthorized* seller jumped the gun, he could easily get blacklisted and never be able to purchase from them again.

Without finding someone else's name to put on the account, I mean.

Canaan also doesn't build bottom-dollar gear and sell for 400% markup whenever it's convenient. By "bottom dollar" I mean built as cheaply as possible, spec'd too high for reliable long-term use and shipped with a mediocre warranty.

Bitmain is entirely self-serving. Sure they make hardware available to the masses, but they're in direct competition with their own customers and have little qualm about openly ripping off the entire world. The whole Cash shenanigan didn't help matters at all.

Well how about that. Yet another good reason to add to my list of "never sell shares or take investments". Why would a lawsuit in any way solve that problem? After the initial offering, isn't share price determined entirely by market speculation?

Also, 21e6 really seemed, from the beginning, to have very little idea what they were doing (or how to do it right). I believe at one time they mined a significant share of the network, but their chips were lackluster and the one "product" was basically a single large-scale ASIC duct-taped to a Pi with about a $300 price tag and no real purpose other than to sound cool to people who didn't know any better. If I remember right, they were one group pushing for Bitcoin blockchain-as-a-service microtransactions (in an already cluttered network) doing entirely-non-currency things, which is pretty counter to reason.

Anyone who says they're doing it with BM1387 is lying outright. That'd be operating the chips at roughly 1GHz, which they're probably capable of doing but not at 0.05J/GH - probably more like 0.12J/GH to push that speed and definitely not with air cooling.

The first step to addressing a warranty concern is, talk to the person you bought it from.

Yep, probably still got some.

Sounds like the common factor is your hub. It's probably weak, or at least has weak wiring for internal 5V distribution. When a new stick is plugged in, the current draw to light it up probably causes a sag on the internal 5V that trips up one of the three sticks.

Or there's some signal issue with your hub that's misbehaving with multiple USB2 devices (which these are).

Have you looked around to see if other people had problems with that model hub?

Plenty of ideas, but it's not too helpful without knowing what you've done to get there.

Is your kit plugged in backward? Did you disconnect the 18-pin cable to the control board?

What is the third stick? Your previous post makes it sound like you have two 2Pacs and one of something else.

Not really sure what that question means. The point of GPUs, and then FPGAs, and then ASICs, is that you don't need the CPU to mine.

More likely a faulty RF pin on chip zero.

What I mean is:

zero energy - Utilizing carbon-neutral renewable energy sources does not mean zero energy is required.

stake mine Bitcoin - this is impossible. "Mining" and "acquiring" are two different processes. Bitcoins are only created by proof-of-work hash mining. Any other means of acquisition is a form of purchase or trade, sourced by actual miners.

on any pc or cellphone - but it sounds quite a bit like any "work" is being done from your solar-powered server farm, not the end customer's devices.

I guess that the process starts on April 24th is probably factual.

Nothing in that article convinces me that anything in the title of this post is technically true.

Spoofing the tach signal is almost trivial. I could conjure that circuit up over a weekend and have 'em mass produced within probably six weeks. The real question, which this is the first time I've heard of it, is if the S9's controller actively monitors power draw on the fans. If that's the case you'd want a dummy load of some kind, which becomes non-trivial since those fans can pull 30-40W at full tilt. If the whole thing is immersion-cooled, a dummy load becomes easier to pull off because passive cooling requirements are relaxed.

You could probably run it off dial-up.

My 100KW datacenter is connecting roughly 70 machines to probably a dozen different pools on three different algorithms and uses less than 1mbit of traffic. Not sure of the exact numbers offhand, but it's pretty low.

Also make sure your soundproof box isn't heatproof or your miners will start to bake pretty fast. Also when considering your battery backup, recall that the miners will be pulling about 100 amps each.

Yeah well, Windows 10 sucks.

DOA? That's weird. They're tested thoroughly before shipping out. PM me to discuss options for resolution.

The temperature sensor is under the heatsink, in the exact center of the chips region of the board. That way it measures the chip temperatures more accurately than if it was on the other side of the board like a lot of miners do.

There's no "expected temperature" for any speed, because the temperature will depend on ambient temperature and voltage setting. If the temp sensor hits 80C, the miner stops mining until it cools down to below 70C.

Future versions will probably have the temperature sensor tied into a USB-connected controller so cgminer can give you temperature readings like big miners do.

Flippin' twit.

No, it's a permissions issue and I believe the solution is covered in the first post.
