Hello everyone,
what's a good price for the S9 14TH/s today?
Is 3500$ honest?

Thankyou!

I mean no disrespect, but why in the world would anyone pay a $1,000.00 premium for a machine with no warranty?

You need 220v for consistent and correctly operating miners. Anything else is pretty much a waste of your time and money.

243  Bitcoin / Mining support / Re: s9 stops hashing at pool after awhile.... on: February 23, 2018, 05:44:31 AM
Hey,
I have an s9 that hashes great for a few hours (anywhwre from 3 - 8hrs), then the pool I'm at stops receiving.  Not just momentarily either, this last time it stopped for 3 hours (didn't check it for awhile...).  The gui on the s9 shows it's still hashing away just fine, and it shows all pools alive.  Once I reboot the machine, it hashes fine for awhile and then stops.  I use 3 mainstream pools (viabtc, slushpool, and Nicehash) and it doesn't hash on any of them for more than a few hours before conking out.

I'm using an APW3++ PSU on 220v, so power shouldn't be an issue.

Any thoughts?

Sounds like network connectivity issues. The miner GUI allows for some very basic troubleshooting. You should take advantage of that the next time you think it drops.

Some other things to check, what's the temp? Are you 110v or 220v?
244  Bitcoin / Mining support / Re: How many amps to my home for 75 S9s? on: February 23, 2018, 05:42:19 AM
Wow - so probably over 500 amps to my home. I know it may vary, but is that normally possible for a residence?

By the way, I can't thank you enough for this analysis...

This is exactly why I recommended you find out how much you can get *before* ordering anything

...

If it were me I'd give them static IPs and just be done with trying to do DHCP reservations. Also, as mentioned, port forwarding is a really, really bad idea. This could be part of your issue as well. I'd probably pick up a router that does VPN and reuse/sell that wireless one.

How is that router connected to the colo's networking? Wired, wireless?

Just looked at it, I like the idea of a DEX, but there's pretty much nothing happening with LCC.

Fair enough, I did not realize it was so recent. Sent over 10 coins to play with Smiley

249  Bitcoin / Mining support / Re: Antminer S9 changed eu stratum pool itself and not others? Strange... on: February 22, 2018, 07:01:20 PM
thank you,

I precise I know how to configure my miner ( basics )  Wink

Ok it can feel to be a dumb question, but it's hard to explain in no native language.

As I wrote below, I think it's not a hack problem, because it does not swap to an other person pool but to my other pool choices, and I wonder why since my others miners are configure the same on the same pools, with same ports; and they stay stable on first pool choice.  





-Some s9 miners could loose pool connection more or less than others ?  Huh

-Someone know what lines I could check to know if it's due to an issue  in the kernel log ?


thank you very much


Gotcha. First thing that comes to mind is a bad patch cable or a bad switch port.

It's true that I have a little bit of everything as patch cables ( not all the same, did with what I had in stock ) and my 8 switch port is : D link DES 1008D

No idea if it can be check ( network issues ) by any way else than change cables or buy an other switch ?

Change the cable and switch port from a working miner. That should help you narrow it down.

251  Bitcoin / Mining support / Re: Port Forward Antminer s9 with TPLINK MR3420 on: February 22, 2018, 04:10:37 AM
Hi
I tried forwarding s9 ports but it's not working. Tried many options as well.

I am applying following settings:
Service port: 8080
Internal port:80
IP address: 192.168.5.101 (my miner address)
Protocol: All
Status: Enabled

When I open my browser and put my ip. 203.10.10.1:8080 it simply do not work.

Please suggest.



are you to get the port forwading work? i think i stuck with same issue as yours.

This is an absolutely terrible idea, do not do it.
252  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: February 22, 2018, 03:56:43 AM
I started mining LCC to HODL, not to sell.  The lack of a market this early on in its development concerns me not.  It could be argued that no market makes them cheap, just as much as no market makes them expensive.

Lets see how these turn out.  Only time will tell.

In the meantime, I'm happy to give my miners to the project.

Fair enough and I wish you luck. I am just very leery of this whole setup, althought BCash is still around so you may end up laughing all the way to your bank/wallet Smiley

I also have to give a big I told you so to the people who said I was wrong that folks would find a way to use SHA256 miners if BTC ever died!
253  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: February 22, 2018, 03:18:27 AM
With 2 x S9's I mined about 9 LCC during 24hrs.

So I took my own advice and threw 4 s9's towards mining LCC and after a 24hr pull I was able to get 32.5 LCC. Current price of LCC is $5.44 so each of my s9's are currently making $44.20 per day. With LCC slow block start the blocks are not even hitting their max of 250 LCC per block yet they are only up to about 175 per block right now. One of my units even hit a block of 159 LCC which would have been over $800 if I was solo mining. If LCC holds it's price it is currently much more profitable to mine then BTC.

It might show to be more profitable, but good luck selling it. YoBit's wallet is down so you cannot move any LCC to it to sell, luckily the price has rebounded somewhat. Who knows what the price will be once you can deposit LCC, and who knows if any good exchanges will pick it up.

Happended today again... Undecided

As it take time ( for me I don't know if it's usual ) for my miners to reach the max Hashrate ( it can easely take up to 30m or more ) I can miss blocks and hash score...

Apparently you are not sure how to correctly configure your miner. You can put up to 3 pools in the miner so if a pool has connection issues you can swap to either another pool or another connection to that pool. For instance you could have US Slushpool and EU Slushpool. If connection goes down your miner would swap over to the EU connection.

It's there so you CAN KEEP HASHING... So read up on how to properly operate your miner and then find out why you're dropping connections to your main pool. Also learn to properly secure your miner, maybe change the password and look over your pool settings.

So I looked at their website and I do not see anything for mining equipment. Do they fully understand what you're wanting to host? In my day job I work with some fairly large hosting providers, and most of them shy away from mining equipment. Mainly due to the HUGE power consumption and heat output. Servers aint got nothing on ASICs.

Yeah, he knows what I want to do. He was even helping me decide between colo and self hosting. I had like a 30-minute conversation with the guy today on the phone - super nice. He's sending me the proposal tomorrow, so I'll know more then Smiley



Then you're on to something.
256  Bitcoin / Mining support / Re: Antminer S9 Cooling - Refrigerator / Cabinet on: February 21, 2018, 04:28:07 AM
There are a lot of ways to skin this cat, but a fridge is not going to work due to the CFM that runs through these things. Best to vent the miners out of the garage or building and put in some extra A/C. One option for you might be to build a shed or buy a used shipping container to house the units. Vent them outside and install some good A/C. I have mine in a small "mother-in-law" type house with a couple portable 14,000 BTU A/C units installed with miner exhaust being vented through the floor to the outside of the building. I am in the South as well, and this solution works fine for me. If I did not already have the little house, I would buy a used shipping container - they are cheap, well constructed, secure, and easy to modify for special projects like this.

Yes, shipping container is definitely a possibility. Insulated properly and with really strong airflow even in the South I believe it would be a great hosting space. But back to the initial question, I think I would look at simply insulating the walls between the garage and bedroom better. Heck even putting up cheapo Harbor Freight moving blankets on the garage side would most likely reduce the noise quite a bit.

I am lucky, the way my house is built the guest bedroom is against the garage wall and is very far back. Standing at the garage entrance door, but with the door closed is about 60dB. That's really the only portion of the house you can hear the miners.

Thank you for the reply.  I will PM you, I am in the DFW area..

I did look at your post on ducting - and yes I will take your advice and first focus on the heat waste issue - getting the hot air that these units kick out somewhere else..   I will do that first, and then address the incoming cool air issue when needed, which is likely 2 months away..

But other main issue I want to address is the noise.   Of course my bedroom wall where my bed is against, the garage is on the other end.  With sheetrock in between I can still hear the humming of the miners (even with some ducting).   2 miners was not bad, 6 is a little noisy..

So I am thinking of putting them in an enclosed cabinet for noise, which still having adequate in and out air flow.   Anyone try this?

Definitely PM me. My buddy and I found the perfect building with the perfect landlord just West of downtown Fort Worth it's clean, in a nice area, has plenty of power, the guy doesn't care what we do with the interior, etc. Problem is (and this is a good problem) it's too big @ 5,000 sq/ft! So we cannot justify the lease @ $2100.00 a month right now. We both want to slowly ease in to mining at a larger scale.

Yeah - I found a place down in Tampa that will host them and service them for $135/month/device. Legit data center (https://www.synergyisp.com/)...I'd get badge access, can tour, VPN, etc.

It was just the year long lease they wanted otherwise I agree 100%. Maybe I can negotiate...

135 plus electricity right? Or that all in? The other poster said 35.00 which is crazy Smiley

It's 135 for everything (elec. + hosting services)

That's a damn good deal. Almost too good, I would definitely travel there and inspect the setup. Right now at .057 kw/hr not counting delivery fees etc I am at $57.46/month for one S9.
