281  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: June 01, 2018, 01:02:36 PM
My point is your GPU ROI 4 times over since 2016 but had u just buy ETH instead, u would have made more like 50+ times over since eth was 10 dollars then..

I think they are always looking for new coins. They will probably have a miner for every algo one day lol.

I mine for a living.  I am my own employee.  My wife stays home to home school our son.  I trade and mine.  Those who don't have employment with someone else may not have extra funds to HODL coins since 2016 and may require revenue coming in to make ends meet.  Don't get me wrong, I've done well for myself in both mining and trading.  I'm simply pointing out it's not always as cut and dry as you make it sound.  

Everyone has different circumstances and can only do so much.  For instance, I know an individual in my town who is handicapped and cannot find a job with decent pay.  They do get a disability check monthly from the government but barely keeps him in a cheap apartment with utilities and food on the table.  He began mining in 2013 and has slowly built up his mining farm in his apartment to supplement his disability check and save a fraction of what he mines to HODL long term to hopefully see better days in a few years to come.  It's just not as cut and dry as you say.

The point I'm making is BITMAIN doesn't give a damn about the small guy.  The small guy is who they aim to push out; in favor of large scale operations to do business with.  Even then, the large scale clients of BITMAIN will ultimately be defeated in mining power.  

ASIC Resistant algorithms give the small guy incentive to get involved with a decent reward for themselves.  ASIC Resistant algorithms encourage new people interested in crypto to get involved in the space.  ASIC Resistant algorithms increase the size of "community" and attracts more to the space with GPU mining.  The advantages of GPU mining for the "community" far out weigh that of ASIC's dominated by one manufacturer.  Those advantages can be culminated into a list here but this is not the forum for such a post.

Just had mine delivered.  I cannot get it working with the ZEC pool's for Suprnova or Slushpool.  Error is something related to "extranonce"..

On Antpool, the "dashboard" after 20+ minutes shows nothing - so although am getting some shares accepted, I can't see assurance from Antpool's dashboard that they are being recorded..

The fact that this doesn't work on all pools is a bit disconcerning!

Well, looks like their so-called "testing" before shipment wasn't done very well.  Looks like you'll have to wait for a driver update to mine on other pools.  In the meantime, BITMAIN will earn more coins from you by forcing you to mine on THEIR pool.   Cheesy Cheesy Cheesy

Honestly I have my doubts this first batch will ROI without a rise in the coin value (unless you have cheap or free power). Maybe grab a coupon or two from a board member if you want to buy one.

I have heard Zencash may not fork, but I know BTG will, which is why I'm bummed I'm not mining it right now while I can.

Please do your research before stating a "rumor."

Can anyone pls comment on official ZEN statement on ASICs and changing algo to ASICs resistant, but in a short quick way.
whats the TLDR version?

Thanks.
Potential Equihash Algorithm Change Preparation

Modifying ZenCash to use Equihash-144-5 is doable, and the software development team has started identifying the specific work that would need to be done in order to create and test this change. It would be a Hard Fork change, and for optimal success of the Hard Fork, it would be best to implement such a proposed change as quickly as reasonably possible before too many ASIC miners take over the hashrate of ZenCash.

I have a nice cold basement that keeps cool even in this 90% heat.

This mining room is in my basement next to the garage.  I guarantee you if you had 38 rigs like myself, you would be FORCED to do something similar to what I'm doing in order to keep your rigs cool.  If you didn't your rigs would be shutting down a lot from getting too hot.  Not to mention how the excessive heat can shorten the lifespan of your rigs.

Here's a look at the wall with the door from the inside.  Please ignore the disorganized wiring.  It will be sorted out when I add two more Power Distribution Units and one more 16 port switch.  New electrical will be ran as soon as I can get the mining room enclosed and sealed properly.

287  Alternate cryptocurrencies / Mining (Altcoins) / Re: Lets Share Ideas of Ways to Manage Heat From Mining in a Home or Warehouse on: June 01, 2018, 11:32:05 AM
New 28 inch x 80 inch door installed.  I still need to install the door knob.  The old 30 inch x 80 inch door from the old mining closet was too wide for the space available.  So, I had to go with the 28 inch door.  The old door will be stored away in the garage or trashed.  I haven't decided yet.

It took me a while to figure out how I'm going to finish the back side of the 48 inch wide rack with the old door leaning against it.  I plan to finish that this evening.  I also need to trim out the top and corners to seal them in to keep heat from escaping into the cool isle.

In case you're wondering, self tamping hex nut metal screws were used on the outside to screw the plywood into the metal racks.

Here's a look at two of the three fan frames completed with fans properly braced.  You would be surprised how all the fans want to fall out of their cube without bracing if I were to turn them all on.  Found that out the hard way.   Cheesy Cheesy Cheesy  The air pressure generated from all of them on pushes them out of their individual cubes.

289  Alternate cryptocurrencies / Mining (Altcoins) / Re: Lets Share Ideas of Ways to Manage Heat From Mining in a Home or Warehouse on: June 01, 2018, 03:28:39 AM
As you can see from the photo below, I have the sides of the racks covered with plywood.  Even the 48 inch wide rack on the left in the photo has it's sides covered.  I'm going to finish roughing in the frame and install a 28 inch wide door this evening.  I'll also install plywood on the back of the 48 inch wide rack this evening.  The door needs to be installed first because of the suction created from all the fans.  Hence, installing the plywood on the back of the 48 inch wide rack last; because of that suction.  I'm afraid the door would be more difficult to install if I installed it last because of the suction.

I need to purchase eight more fans to have on standby for the 48 inch wide rack for a future date when more rigs are hopefully added to the mining room.  Which means, if and/or when I add more rigs, I'll need to make a "fan frame" that holds eight fans for eight rigs in the 48 inch wide rack.

I'll install new electrical overhead to replace the temporary electrical you see running on the floor once the door and walls are completed.  Wire management will be saved for last.

I believe they CAN and WILL deliver.  Those who don't they can deliver will be left behind.

I love this, how crazy ideas work and in fact its not really crazy or stupid, its like a form of resourcefulness or gracefulness in batlling heat during mining. I love how he does this. And typically can help ideas to other on how to manage difficulties as such.

Thanks!

Much appreciated!

I wish the other thread on "Miner Photo Porn" was not deleted.  I had over 500 posts in that topic alone with close to 100 photos of previous mining rooms that started out small and got larger over time.  I've experimented a LOT with best possible way for heat management since 2014.  Even tried air conditioning.  Of course, that did not work either.  The amount of money one would have to invest to have enough air-conditioning to cool down this number of rigs would be very expensive.  I have 38 rigs in total.  I have several in my office that will be placed in this new mining room remodel.  I'm just looking forward to completing this so I can move on to other things.
What is the power consumption of you box fan ? and how many graphic cards card it blow air on/off ?
I bought on AliExpress a bunchload of 14cm fan that can be used for two cards and they use only 3w so a 12 card rig can be managed with 18w (but airflow is probably lower than with a box fan)

The particular one I own is the following:

Low:  27 watts (30)
Medium: 73 watts (75)
High: 119 watts (120)

I have mine blowing on 7 cards in 23 inch wide rig cases.

The amount of heat generated from 38 open air rigs needs these box fans for the room downstairs I have them in.  And the fans need to be properly sealed around the top, bottom and sides to keep heat generated by the rigs from getting sucked back around the bottom, top and/or sides of the fans and blown back onto the rigs.  If it's allowed to do this over and over again for a long time, the rig will only get hotter and hotter like a convection oven.  At least in my case with how many rigs I have.  You would probably be alright without sealing around the top, bottom and sides of the fans if you don't have a lot of rigs.

I purchased 40 of these fans.  I have 4 spares:  https://www.homedepot.com/p/Lasko-Weather-Shield-Select-20-in-3-Speed-Box-Fan-with-Thermostat-B20573/206441059

What is the hydro service you are running this on?  400amp 240v?

I'm running all of this on the same power grid as most everyone else.  My power company has both hydro and clean coal power generation.

Yes, I have 400 Amp service at my home.

I have a total of nine (9) 240 Volt 30 Amp Power Distribution Units (PDU's) for the rigs and four (4) 120 Volt 20 Amp circuits for 36 x 20 inch box fans and two (2) x 30 inch intake and exhaust fans.
294  Alternate cryptocurrencies / Mining (Altcoins) / Re: Lets Share Ideas of Ways to Manage Heat From Mining in a Home or Warehouse on: May 29, 2018, 09:21:13 AM
Summer is on the outside, time to chill.
I am create yesterday box how tunnel and from one side screw 2 9sm fans from foxconn. Connect +to 12V - to 5V, its wroking silent but cant chill 3x RX550 AMD cards, i want buy variable resistance and search optimum fans speed.
If connect it to +12V noise is very high frm this fans

I've found [For the price paid for 20 inch box fans verses 120mm or 140mm computer fans] it is more cost effective to get 20 inch box fans.  I've also found 20 inch box fans to move more air for the amount of noise they generate verses 120mm and/or 140mm computer fans.

ALSO:  To get 5 x 120mm or 4 x 140mm fans for each rig and seal them in plywood with holes cut out would have required a lot more labor to cut out all the holes I would have required for 38 rigs.

And all coins that u mine via gpu, such as eth, has increased in value like 50-100 times over...

Which means I made the correct call selling all my S7's in February, 2016 to begin purchasing hardware for GPU mining.  I "knew" better than to invest my funds from S7 sells into the new S9 at the time.  I saw much more potential for increased revenue with GPU mining instead of BITMAIN (ASIC) Mining.  I also liked the concept of getting back to GPU mining to rid the community of one manufacturer who dominated the space; which resulted in centralized mining by big corporation(s).

Phillip, told the truth in his comment just below my previous comment.  Bitmain is looking for another coin to gain an "edge" once again.  They're hoping the Equiphash algorithm will give them the edge they seek.  Currently, it's not looking so well for them with BTG, EXPANSE, ZEN and Bitcoin Private all saying they will fork to remain ASIC resistant.  If ZEC also ends up changing their algorithm, it's not looking good for Bitmain.
296  Alternate cryptocurrencies / Mining (Altcoins) / Re: Shared Ideas of Ways to Manage Heat From Mining in a Home or Warehouse on: May 29, 2018, 02:37:22 AM
This one rack will be left alone because it is already placed where it will remain and already has a 12 box fan frame built and attached on the back of it:





OMG. This is awesome

Thank you very much!  Still a work in progress...

I'm about to get back to it.

Cheers

Those of you who paid top dollar for the S9 in December and January are beginning to wonder if my assessment is correct now, aren't you?

No because most of what you say is misinformed and ignorant.

Ill put any thousand of my S/T9s against your dumpy lil GPU rigs and we can compare profits.

No, you'll put your T9's against everyone else on a network hash rate that has more than doubled since January 1, 2018 [See chart below].  ROFL...  Good luck with that.  

I'm still mining with GPU's at a profit that I purchased in early 2016.  They have ROI'ed more than 4 times over.  Grin

298  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain launches the Z9 Equihash miner on: May 28, 2018, 07:48:32 AM

79 being ready to ship may imply that that’s what they will ship everyday. So to fulfill all batch 1 orders in approximately next 30 days means 79*30 ~ 2400 miners in batch 1. Let’s round it to 2500.

Sounds about right.

Hi dmwardjr,

I am now working on flashing. I wonder what settings I should use for the following cards for lowest power consumption. At stock setting, they are using 190-200W each. It's pretty high for me. I'm ok with 20.5Mh using stock setting but wanted lower power consumption.

Gigabyte 4Gb _ Hynix
Powercolor 4Gb_Elpida
XFX 4Gb_Elpida

I also could not find a modded Bios for my Gigabyte card on Anorak. If you have, please share.

Thanks.

I still have stock BIOS in my 380's.  I'm going to use AMD Global Wattman settings to make an ATTEMPT at better power efficiency once my mining room remodel is completed:  https://bitcointalk.org/index.php?topic=2865914.100
