They did get back to me last night, asking what kind of demand I'd have. Haven't heard any more yet but hopefully they're willing to work with someone who'll have to start small (my chips budget right now is only five figures) and snowball instead of dumping in a quarter million dollars up-front or whatever.

Yes, I am interested in samples and dev resources. Depending on what IO bus they use, it might not be difficult to re-tool my current projects to a new chip and it could very well be worth it if the chip's 30% better than what I have now.

I wonder how long it typically takes them to respond to inquiries, because I've heard nothing yet.

Definitely interesting. Gonna follow up on that, thanks for the lead Fuzzy.

Yeah I hear you man, if only that incredibly common problem were answered in the FAQ section of the first post.

...oh wait



Or maybe if it was solved in the README file, like the error message specifically states the user should check?

...oh wait



Don't accuse "the big guys" of not giving you enough info. Rather, start paying attention.

300ghz, or 300GH/s? Because there's a big difference between those two and one of them shouldn't be possible without having broken cgminer first.

I'm guessing the white light stays lit on that stick. This generally means one of the ASICs has died and you should seek warranty replacement (assuming it's not the result of abuse).

Maybe 500 jobs temporarily for re-tooling the location, but to keep 500 people occupied maintaining a facility it'd have to be a couple hundred megawatts of machines.

I wonder what they're going to do about the billion-degree heat? South Texas is too hot for their high-density miners for about half the year.

Has zero effect on your hashing hardware. All this does is lower the pool traffic. You don't send lower-value shares, but the shares you do send are weighted higher to make up the difference in your payout calculations. If you set the number too low, the pool automatically increases it to mitigate traffic. Usually set to around half a dozen shares sent to the pool per minute so the pool knows you're still connected and active, but not enough to appear spammy.

Nope, hence why there's no mention of them in the original post, original post's update or the update post. Pay no attention to stuff from three months ago. The R808 is gone and it's not coming back.

Gosh I hope not. I'm finally starting to relax a bit.

Made, or taken? Because some can see trading pumped shitcoins for something with real* value as "selling magic beans". If you're not creating value, you're taking it from somewhere else, hence why mining bitcoins and mining alts to trade for bitcoins are philosopically quite different.

*based on utility as a widely-accepted means of exchange for goods and services

Eyeboot does make pretty solid stick-minering hubs. All my test stations are Eyeboot hubs, and that's not a compensated endorsement. A few minutes of searching will turn up a number of other recommendations for the 10-port neighborhood. The most important thing to consider is total available power; secondary to that will be harder to verify, and that's the strength of the internal power wiring. USB2 versus USB3 will mostly be a matter of compatibility with your controller, because the sticks themselves are USB2 devices but operate at approximately zero bandwidth compared to the USB2 spec. Power is the limiting factor in most setups.

So, Laura's had to go back into treatment. As it happens, I have some 2Pac Factory Seconds available again. It's a coincidence though, and we were all hoping she'd never be in this situation again.

If these don't sell, they'll be stripped for usable parts and recycled. So I'll sell them for $10 over the value of usable parts and that extra $10 will go to help her cover costs, same as always. Current going rate is $16 plus shipping. Once they're gone, they're gone.

Doesn't seem like it's helping the time to market if they're not gonna be shipping units for three months anyway. Making a case is a heck of a lot faster than making enough 7nm ASICs to put in it, and getting them installed on the boards.

Canaan's machines are better thought out in pretty much every way. If I'm remembering right, Canaan was started by the engineers left in the rubble of Avalon ripping off most of its customers and skedaddling with all the money. Putting more engineers in charge of a product instead of bean-counters is probably a good way to go if you want something to actually work well.

You mean like literally everyone was doing before the S7 became popular? And like Canaan still does?

The narrow tube design with heat sinks packed in like cotton balls is a lazy way to put way too much power in a tiny box. A tiny box nobody's asking for. A tiny box that substantially reduces system reliability (not just by baking the crap out of your silicon, but by relying heavily on overtaxed mechanical components like high-speed fans and assumptions about ambient conditions - these would die rapidly without chilled, dust-free air), in a time when breakeven returns will take a year longer than the warranty period.

It doesn't really take boldness. Just takes common sense, a little bit of extra R&D and prioritizing providing durable quality hardware to the customer over making immediate large profits.

I wondered about that.

I also wondered - why make a machine for which that's necessary?

It's true. All the software is free and you can get a PICKit clone for like $20.

Workin' on it.

If everything's working correctly, you should be seeing WU of about 1.53 per MHz.

gvb, your HW is very high so the voltage is probably too low. But it sounds like your USB available power is keeping you from being able to turn it up further. At 212.5MHz you should see 23GH and WU around 325 but I think your error rate is keeping that from happening.

It's one half the value shown. Each chip gets half the total voltage.

Frequency is a command-line argument, so you have to close cgminer, change the startup command and re-run it.

Most people don't really need to measure the voltage directly if you're only making a relatively small change to the frequency. Just keep a watch on your HW, and if it starts to go up, you need to turn the voltage up a bit. Righty-tighty, which is to say a clockwise rotation will increase the voltage.

The heat and noise are both a factor of power density, which also has an adverse effect on longevity. Home mining's biggest issue is manufacturers who think it's appropriate to stuff multiple kilowatts into a cracker box.
