161  Bitcoin / Mining speculation / Re: Rumor that Bitmain is going belly up! can't pay its chip builder! on: December 10, 2018, 10:20:15 PM
Ill cherish the day when there are 10's of millions mining bitcoin on their 100 watt machines, and could care less what what it costs to mine since a single light bulb wont make a dent in their power bill, and this causes all centralized mining farms to go belly up.

THATS the true vision of Bitcoin, and anyone that disagrees does not get it.

You sound pretty delusional if you ever think this is going to happen. Where there is profit to be made, people will turn up to make that profit. It is incredibly naive to think you can put the genie back into the bottle at this point.

Cheap ass power supplies dont always regulate their fans, i have seen plenty that are 100% fan speed all the time
163  Bitcoin / Mining speculation / Re: Will btc difficulty go sideways for rest of the year? on: December 05, 2018, 06:17:50 PM
I have run into three separate situations where I was buying gear from " Hosting " facilities and or Colo set ups. Each time I was shocked at how little these operations knew about basic cooling and infrastructure. Their "floor costs" or infrastructure costs were astronomical. I believe a lot of these miners that are for sale on the secondary market in US and Canada are coming from these poorly planned build outs, that just threw large amounts of capital at them without understanding the metrics of the operations. Even at the most basic level. I believe there are still many more to follow. Not only did "fast money" over speculate BTC itself, it went "All In " on Colo, Reselling of Gear and every other facet of this business. I suspect the shake out will continue until all the Wheat is separated from the Chaff.

You hit the nail on the head here. As someone who has been doing this at an industrial level longer than most I have seen soooo many poorly designed and poorly ran datacenters pop up and die a horrible death shortly after. The only way to survive in this industry is to run very lean in all phases of operation at all times regardless of profits or how well the market is doing. What i have always done is ride the waves up by reinvesting and expanding when times are good so that when things are on the downturn you can survive by the sheer size of your operation. Most people getting into this game make a few major mistakes. Mistake 1 is build costs, the way to build is leaning on the secondary market. Electrical infrastructure has not changed much in the last 50 years, a transformer is a transformer. As an example, I picked up used 480/208 step down transformers for pennies on the dollar used while I watched other places pay tens of thousands of dollars for brand new equipment where im paying maybe 10% of what they are for used equipment that functions just as well. With over 20mw of power in use I have not had a single used transformer fail. Another thing I consider a mistake is buying PDUs new. These can easily run into the high hundreds per piece new, whereas I have over 3000 active PDUs and none of them cost over $100 thanks to the secondary market.

The second big mistake is in operational costs.

I know of 5mw datacenters with 20 technicians on staff and even with all that they still are lucky to keep a 90% uptime. I have done the exact opposite, I have a small team for a very large space but we have created efficient processes and monitoring tools in house to greatly augment the efficiency of our team. With an average of 12000 machines online I can claim (with proof) we keep an over 99% uptime with a staff of less than half a dozen. Only by keeping operational costs as low as possible and reinvesting as much as possible on the upswings can you survive here stateside. When you factor in insurance and taxes and tariffs and everything else, overall costs can stack up quickly and most people starting these datacenters with the dream of lining their own pockets will never have a sustainable business model. You survive by stacking and saving and being prepared for the volatile market conditions that are guaranteed to happen.

Its showing you have zero fans from that screenshot which will cause all kinds of odd problems. Im not sure how you have an uptime over a few minutes with no fans reporting in

You should post about what you did to fix it, you never know who might stumble upon the post and need the help.
167  Bitcoin / Mining speculation / Re: Anybody here suing Bitmain on: December 03, 2018, 06:19:22 PM
This is so stupid.

Why is only bitmain being sued? What about every other miner manufacturer in existence?

When you violate a law you cant just claim ignorance, why is a customer claiming ignorance a reason to sue?

Also with how long the auto tune firmware takes to get started, there is absolutely no merit behind the claims. It takes 10 seconds to update pool information.
168  Bitcoin / Mining support / Re: Strange problem with miners, help needed on: November 30, 2018, 08:45:00 PM
According to your kernel logs "bmminer not found, restart bmminer ..."
This might be the reason why the miner keeps rebooting. The only way that I know you can fix this is to reflash it with other firmware.

Can you try to flash it with this firmware Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz
Or downgrade it to "November firmware".

The November firmware is well known to cause many problems including the bmminer not found issue. I would NEVER recommend this firmware to anyone.
169  Bitcoin / Mining support / Re: Strange problem with miners, help needed on: November 30, 2018, 06:45:51 PM
Can you post the logs of the machines that keep restarting? That would help immensely in trying to troubleshoot the issue.
170  Bitcoin / Mining support / Re: Antminers doing better Accepted/Hour after a couple of restarts on: November 29, 2018, 09:37:49 PM
Yea I was more recommending testing on another pool for a day just to see if you see the same strange behavior, as it would give you a clue if it was poolside or something else.

I run my test miners on Kano.is pool personally, its an easy no hassle pool and you can set the difficulty in the console if you need to (which I have had to do in the past with ebit machines)
171  Bitcoin / Mining support / Re: Antminers doing better Accepted/Hour after a couple of restarts on: November 29, 2018, 06:11:08 PM
If you are using nicehash and your hashrate is being moved to different pools and pointed in different places the accepted shares is a pretty meaningless stat. Different pools have different difficulty targets which change the accepted shares. Hashrate will look like its going all over the place as you bounce around between ones. I recommended you getting on a stable pool to test for these reasons.
172  Bitcoin / Mining support / Re: Antminers doing better Accepted/Hour after a couple of restarts on: November 29, 2018, 04:49:40 PM
No i dont mean for profit, I mean as a control test to see if the miners act the same way on a standard pool, sorry I should have been more clear.
173  Bitcoin / Mining support / Re: Antminers doing better Accepted/Hour after a couple of restarts on: November 29, 2018, 04:10:32 PM
Try pointing your miners to a real pool and not that nicehash junk and see if they act the same way, which I doubt they will.
174  Bitcoin / Mining support / Re: Antminer s9 chip loss after cleaning on: November 28, 2018, 05:23:24 PM
It's interesting that they all don't have the exact same program inside  Huh, but I think the hex file for all of the boards are just fine.

The auto tune software runs tests to determine optimal settings for voltage per card and then applies them so I would think it is completely normal to see the differences you are describing per PIC.
175  Bitcoin / Mining support / Re: Step Up Converter Question on: November 26, 2018, 11:13:06 PM
This is a very bad idea for a number of reasons.

Reason 1: Unless you are paying $0.04/kwh you will be losing money running it.

Reason 2: Step up converters are not meant for a continuous 1500 watt load like you would be trying to apply and chances are it would burn up and be a possible fire hazard in your house.

Reason 3: You would be buying yet another piece of hardware and making an already nearly impossible chance at ROI completely impossible.

Sadly the T9+ is nothing more than a doorstop at this point, it never really had a chance to be successful.
176  Bitcoin / Mining support / Re: S7 problem on: November 26, 2018, 07:47:45 PM
First problem is your controller is not reading your hardware properly.

It is showing 48 chips per board which isnt possible. There are either 54 or 45 chips per board and neither will function with more than 3 chips not functioning.

I would check what firmware you are running and make sure it is the proper one for your boards.

What about a 30a 240 line? think I could squeeze two?

2 would be a minimum of 33 amps....I wouldnt recommend it

edit: I guess if you fed it a full 240v it might only draw 15 amps each, still way over the circuits continuous rating

1. You need to post this in the altcoin section, this is for bitcoin mining only so you will not get many useful replies.

2. The market is in free fall, it is hard to recommend buying new hardware at this point.

That is 1 unit per 20 amp circuit.  Damn

Yep, its currently pulling 16.7 amps, my poor PDU is flashing and begging for relief but its pumping out a steady 55.2 TH over the last 20 hours or so.
