361  Bitcoin / Mining speculation / Re: Is this possible? on: January 30, 2018, 03:16:34 AM
Hi, I am new to this cyber mining.
Now there are all of these miners.
Looking for clients with cyber wallets ect.
I have one guy telling me he can take 580.00 0.05btc and turn it into $ 8,000.00 0.7btc within 48 hrs!
Is this even possible?

No
362  Alternate cryptocurrencies / Mining (Altcoins) / Re: What are you mining right now ....and why? on: January 30, 2018, 02:57:27 AM
When ZCL was up I was mining it, now everything except for one ZCL "donation" rig is on ETH. I agree though, if you find a coin that you believe in mine it! It's nice being part of a community. I really think privacy coins are going to be the rage in 2018 and I liked ZCL hence my choice, but right now I mutinied and went for a bit of ETH to hedge my BTC losses Smiley


363  Bitcoin / Group buys / Re: USA Group Buy - Antminer S9 on: January 29, 2018, 09:44:41 PM
Thank you for the feedback.    Let me explain a little more..

It is pretty clear why there has not been a group buy in some time, who wants to give their money to a black hole, and hope that a S9 comes in 1 - 3 months?

I also have operating businesses (retail stores).   I have a professional license issued through the State of Texas.  I am not looking to take anyones money.

I am based in Dallas, Texas, and what I want to know is there enough interest for people to place money into a trust / escrow  account, which not a single money is released until the full purchase price of 200 units is reached, and at that time, payment can only be made to Bitmain.

I would do it on a first come first serve basis.  No minimum.  

Would there be interest in such an buying pool.   It would have to be USA and Canada only.   If there is interest, I can share more information.  

I just spent 2 hours at 9 pm and 3 am clicking the refresh button on shop.bitmain.com and wasted a lot of time.  There has to be a better way!

I would be in personally for the first 20 units.  So 180 to go..

  

I am in Fort Worth and might have another interested party. Who would you be using as the escrow?
364  Bitcoin / Mining speculation / EMF,Some Observations on: January 29, 2018, 12:48:01 AM
Jabby brought up EMF in an earlier thread so I thought I would perform some tests. Now these are very non-scientific backyard DIY observations, and no claims are made by me one way or another as to the safety of this equipment. I am just passing on what I saw using a cheap EMF meter. So if you get cancer or grow a 3rd arm IT'S NOT MY FAULT!

The meter I used is here http://amzn.to/2Grg8ov

Alright, so I started roughly 20' away from my 3 miners (2 S9s and 1 S7 all running new Bitmain APW3++). Zero readings on my meter.

10' No reading on the meter

1' from an S9 Jan batch 13.5 TH/s



6.5" From an S9 Jan batch 13.5 TH/s



Right up on the miner



After that I tested some household items.

Regular fan ~12"



Regular fan ~5"



Right up on the fan motor



Breaker panel



Breaker



Brother printer!



Pioneer Stereo Reciver



TV



Microwave running



So I feel that yeah, if you blanket yourself in Antminers it's bad Smiley But more than a foot or so and you do not have to worry. As an anecdote the meter started flashing harmful when I was outside my garage near a power line...

Never mind. I just realized what I was going to do isn’t going to work.

But there is specific guidance from Bitmain when using 2 PSUs.
366  Bitcoin / Mining support / Re: Antminer S9 Not Powering On on: January 28, 2018, 03:56:11 AM
Is the cooling fan for the PSU moving? And you've checked your breaker for the outlet?

Stupidly obvious I know, but 1st rule of troubleshooting; rule out the easy/obvious stuff Smiley

No fan / leds. No signs of life,,
Breaker all good, psu does turn - antminer does not.

Found this, be careful!

Awesome man - thank you! Will check this right away..

Also someone in another thread just said that the S9 will not post at 110V with apw3++ without sufficient wattage .. is there any truth to this?

I saw that, now I've never tried 110v, but the AP3++ will provide power on 110v (up to 1200W). And because you removed hashboards and still no joy I think it's something else. ***BUTT** I would wait for more experienced folks to chime in about that Smiley

I have an used GTX 970, so I want to assemble a desktop for mining, but I don't know what the requirement for CPU to mine the altcoin. I appreciate if someone can give me some suggestions. I hope I put this thread in the right section.
 

May I suggest the altcoin mining thread

370  Bitcoin / Mining support / Some PDU Part#'s on: January 28, 2018, 01:29:45 AM
I know a lot of folks pick up PDUs off eBay, so I thought I'd post some search fodder for the new folks. Surely someone will search before posting right? Yeah I'm optimistic Smiley

Anyway what got me looking around is that most PDUs are not very well suited for ASIC miners. You might buy a 30A PDU, but look at it carefully. Most of the time each bank of outlets is protected by a 15A breaker. So 2 S9s will put you over the 80% derating recommendation and pretty close to the cap, I haven't measure S9 inrush. Use something like a Pangolin M3 and you're down to 1 miner per outlet bank.

Now I am sure there's folks running these 15A/bank PDUs with no issues, but it's too close for me. By doing some digging I found APC part # AP6031A (Dell branded Dell AP6031), which seems perfect for ASICs. 30A total (24A derated), 4 outlets @ 12A each derated. The form factor of this PDU is also a lot smaller so you don't have giant PDUs with a bunch of wasted outlets.

Thought I'd share.

371  Bitcoin / Mining support / Re: Can someone with S9 Experience view my Miner Status.. I'm concerned :( on: January 27, 2018, 02:49:21 AM
Thanks Raymond.

Is there a link or manual that explains the different categories and what they actually mean or refer to?
What are potential limits for these various categories?

Other then keeping temps in not above the 70s and having all zeros in the ASIC Status I'm pretty green.

full link to image: https://ibb.co/ftNMtb

There's really isn't, I wish there was. Search this forum, you'll find that it's safe to run these things quite a bit higher than 70* Celsius. Honestly as long as it's hashing pretty close to its specified rate and not running more than 80C (my limit, others run quite a bit higher) or so just leave it be and let it make BTC Smiley
372  Bitcoin / Mining support / Re: Can someone with S9 Experience view my Miner Status.. I'm concerned :( on: January 27, 2018, 02:31:15 AM
Hey guys. New to mining so I'm not sure if these very large values are concerning or not.



Not sure if this image will show... it might be "you need to post a bit before you can" situation.

If it is and you cant see the screen shot my most concerning value is DiffA# on Pool 0 shows = 2,748,234,968

Chain 6 HW# is = 8495

Temps for all three chips are as follows = 72 (chain 6 chip), 66, 66
Fan 3 = 4,320
Fan 6 = 5,160

It has been running for 10 days 1 hour.

If someone can help me understand that be great. Thanks.


You're fine.

373  Bitcoin / Mining support / Re: THD filter???/ on: January 27, 2018, 02:13:07 AM
For the service?  They are working up an estimate.  Hopefully I won't owe anything after all of the new service credits (50% up front, 50% after one year...$100/kw).  I have to pay for the labor, ditching, wire, CT enclosure, and meter can and everything else on the customer side.  I'm hoping they will accept 4 200A fusible disconnects and 4 200A 3R panels with 4 50A outlets on each.  After I get the jigawatt dealer on my side then I have to convert the code man.

I have an electrician friend who will pull the permit and I'll probably do some of the labor.  All in I expect to pay $5-10k materials and labor.

Gotcha, thank you for the breakdown. I just meant the THD filter Smiley
374  Bitcoin / Mining support / Re: Antminer S9 fan direction on: January 27, 2018, 01:26:38 AM
Antminer S9 13.5 TH Version, Januar Batch
Controller Board Modell 1.20

Hardware Version: 16.8.1.3
Logic Version: S9_V2.54
BMminer Version: 2.0.0

Don't know if this helps, but here's what my Jan S9 shows



Also in the Kernel Log my fans are also labled 2 and 5

Checking fans!get fan[2] speed=4320
get fan[2] speed=4320
get fan[2] speed=4320
get fan[2] speed=4320
get fan[2] speed=4320
get fan[2] speed=4320
get fan[5] speed=5880
get fan[2] speed=4320
get fan[5] speed=5880
get fan[2] speed=4320
get fan[5] speed=5880

Maybe you could start with one fan off just long enough to see which one reports RPM in the kernel log? Don't burn it up!!!

378  Bitcoin / Mining support / Re: Can't Login Antminer S9 on: January 26, 2018, 10:06:12 PM
Synchrouk I just purchased a windows 10 computer and Windows Edge will not let me log into the Antminer GUI. I can get to the password prompt, enter in the correct password, then the computer returns "401 Unauthorized" I've tried dozens of times and tried messing with settings. Still nothing. I just reset the computer to factory defaults and plan on returning it, but I may try to download the chrome browser if that worked for you.

Are you using a laptop? Sometimes there's different weird versions of numlock/10 key. I'd open up notepad and type in it to make sure you're not getting any weird characters. Chrome is also a good idea.

For goodness sake whatever you do, change the default password and do NOT directly connect it!

Looks like a very good design. I was planning to switch from 4" to 5" but after seeing this will go with 6". How is shroud attached to the fan?

It uses the 4 screws that hold the fan to the body.
