I'm working on the official announcement post, but yes it's a real product. The listing is legit; in fact, I'm sitting next to the guy who put it up. He's a newly minted reseller for UK and will have stock in hand in a few days.

Any version of cgminer compiled with Icarus (autogen.sh --enable-icarus) should be able to run this. But yeah the Block Erupter is ten years old, and about three orders of magnitude slower than current USB miners, which are over two orders of magnitude slower than standard industrial miners, so pools aren't really set up to register work volumes that small anymore. Cgminer stats would show you what's going on, but poolside? Kano's solo pool might be granular enough to handle 333MH/s on stats, maybe?

Another SHA coin with a much lower difficulty, you'd be a larger percentage of the network/pool and more likely to see stats. What's the project?

We're full up on resellers at the moment. You're not the only inquiry I've turned away lately, but we do appreciate the interest.

Technically the minimum spec of the R909 is at least 1.5TH from at most 100W, but actual performance should be closer to 2TH at around 80 watts.

Also, regarding editing the nonce range, that's not readily possible without altering cgminer code. Technically I think you can adjust this by hacking the chip addressing scheme during string initialization, which would adjust the range starting point for each chip, but you'd have to also adjust the work timing calculations to account for shorter cycle times per work unit so there's no duplicates, and I'm not sure but this might also affect the statistics calculations behind the displayed hashrate estimates.

Bumping this because I've heard from a few people in the last few days, it's still around and causing trouble.

That step you mentioned is a couple steps which compile the cgminer. What error are you getting? Without knowing what is failing and where, there's not much to help with. Are you doing "dash oh two" or "dash zero two"? Because it's a capital O, not a zero. That's a common/easy mistake that causes the compiler check to fail.

Yes, MHz and GH correlate (until hardware limitations like heat or voltage cause problems) so if you want more GH you need to increase MHz.

It maaaaaaay be a custom job a little bit. Beefy fan on stock heatsinks though; 27 watts into each chip.

I'mma just leave this here

The power output limits of the hub are internal. If your input power can push more than about 12V/12A, the hub itself will be the limiter in how much juice you can deliver to sticks.

If you're going over about 8 amps, you need to use the 6-pin. The barrel is rated for 8A max.

Yeah let's take it to PM

If formfactors and power levels were standardized so swapping boards on waterblocks wasn't basically a customized rebuild with every successive generation - like how S3 waterblocks would fit on an S5 - it'd be a lot easier.

Saying "it's too difficult right now" should be a vote in the direction of "make this less difficult" rather than "don't do it at all" because, quite frankly speaking, bitcoin mining is turning into an ecological disaster and there really needs to be a way to head that off. Harvesting waste heat for other projects would really help. To do something like heat water for sous vide brisket or desalination or a Turkish Bath, or heating air for greenhousing in cold climates or whatever else - it's worth doing, and just because the infrastructure isn't trivial right now doesn't mean it should stay that way. The effluent of shortsighted gain has been wrecking the planet for quite long enough, and recycling energy is a good way to counter that.

Also, and I'm with Phil on this one - brisket. Brisket, guys.

If Merch wimps out on the warranty, it's a Merch problem. I'm interested in seeing this one since it's the first "magic smoke" failure report I've heard in the wild, so if nothing else, you can send it back to the factory for repair.

Heat desalination uses partial vacuums to reduce the boiling point. By decreasing the pressure in consecutive stages, you can heat water once to 80-90C and it'll boil off in one stage, then boil off again in the next, all the way to the last (lowest temperature/pressure) stage.

Where on the board did the magic smoke come from?

Could do desalination as well. A lot of desalination plants are set up next to industrial facilities to utilize waste heat.

If it's measured as pulling the same amount of power but it's hotter, the problem is not the stick, it's your cooling.

Okay but the BM1387 was used on the S9. S5 was BM1384, the chip in the original Compac and the 2Pac.

Standard boost is 4 midstate, lowboost is 2 midstate. Changes the packet size and timings and I forget why exactly but it worked a bit better on whatever janky USB subsystem Windows uses.

For a while I was pulling in 0.5BTC/week with Antminer S1. I had started pretty much with nothing and reinvested or made side money doing repairs and built up a 2TH mine, then switched from "turn ridiculous profits" to collecting interesting gear and traded most of them out for an S2, an A1 Dragon and other cool stuff. The Dragon outlasted everything else, and I bought a second one later not just for the collection but as a heater for the office. It actually had a failed board, which was really weird. I think I pulled the PSU from it for a computer that was still in use about a year ago; pretty solid.

The S4 was a pretty decent machine, tidy and not a lot of noise. S4+ however, went backward in efficiency and reliability. I was consulting for a guy and steered him away from those machines, but his MO was to always do the opposite of what I recommended so he went all in and had a 20% failure rate within the first few weeks. Our working relationship did not last long.
But when I think about cased miners, I pretty much always think about the S4 first because its dimensions and design was just really good.
