61  Alternate cryptocurrencies / Mining (Altcoins) / Re: Number 9! Ninth altcoin thread. Back to the moon Baby! on: August 05, 2020, 03:43:23 AM
Haven't posted here in a long time.  I've been mining non-stop since 2017 and for the last year plus, just with my GPUs (55 total, mostly 1080Ti's) and with my 50Kw of solar, that is covering my power cost 100%.

Phil all those GPUs you sold me way back when are all still going strong!   Grin
62  Alternate cryptocurrencies / Mining (Altcoins) / Re: What to do with limited free solar power? on: July 02, 2020, 11:59:18 PM
I have a 50kW solar system that allows me to run about 10 GPU rigs (56 GPUs total), that gives me a decent profit.  The mining rigs consume about 8kW 24/7.

This table shows my monthly solar production and mining rig consumption.  In the winter time all my rigs are in my house keeping it nice and warm to the point I don't have to run my heat pump at all.  In the summer I keep all the rigs in my shop building.  They use a little more power since I have to run some fans to keep the air flowing:

MonthJanFebMarAprMayJunGrand Total
Solar Production kWh3,9524,3715,4016,6356,3427,12433,825
Total Usage kWh6,1006,1006,1006,2006,2166,52737,243
Grand Total kWh-2,148-1,729-699435126597-3,419


This table shows my monthly "earnings" from solar (my power cost is $0.12 per kWh) and the cost of running the rigs.  So as you can see, in the summer months, the solar generates enough energy to cover the mining rigs 100%.  In the winter, the rigs heats my house 100%, so I would have had to spent that ~$200/month to heat the house easy.

MonthJanFebMarAprMayJunGrand Total
Solar Production $ $474.21 $524.51 $648.09 $796.22 $761.00 $854.93 $4,058.97
Total Usage $ $730.00 $730.00 $730.00 $740.00 $745.91 $783.29 $4,459.20
Grand Total $ $(255.79) $(205.49) $(81.91) $56.22 $15.08 $71.64 $(400.23)

My rigs have all been on Zcoin 100% of the time, so my earnings are pretty easy to calculate:

MonthJanFebMarAprMayJunGrand Total
Zcoin1631391932092362541193
Value (@ $4.25) $694.05 $588.63 $819.37 $886.65 $1,001.37 $1,080.60 $5,070.66

So in essence, I don't pay for the electricity needed to mine, and have had pure profit for the first half of 2020 of $845 a month.

The solar and mining rigs were paid for a long time ago as I have been running since 2017 and was able to sell off quite a bit when bitcoin hit close to $20k.

And AM just keeps restarting the miner.  It has been mining MPT (Zcoin) for the last 6 months with no issues.

Thanks for the details. Can you please try the following:
1) Go to the Options dialog, Statistics Provider section, where you can uncheck "Keep coins even when no longer listed by provider".
2) Save the changes and go to the Coins tab in the main window. Click the "Update now" button and wait a few seconds. Did this remove the older RVN entry?

[/quote]

That removed the old entry and the Exchange Balance now shows the balance for RVN.

Thanks!

Hi Patrik,

On the new feature to show Exchange balances, I'm having an issue with a couple of holdings I have on Bittrex.  They both show N/A for the dollar value.

One coin is RVN and I think the reason is that AM still think this coin is tied to X16r.  That changed to X16rv2 after the fork.  Don't see a place in AM where I can change it.  I was able to change down along the bottom of the AM window where I can keep tabs of 15 different coins.

The other coin is BURST which I know is pretty obscure, but is carried by CoinGecko, so perhaps adding them as a Statistics Provider would take care of it?

EDIT: I was able to fix the BURST coin issue by adding it as a custom coin and pulling the value from CoinGecko.

Thanks
Awesome Miner should automatically list RVN as X16rv2 because this is how it's being reported from WhatToMine.com and CoinCalculators.io. Can you please check on the Coins tab in Awesome Miner?
It's also possible to override the algorithm via the Options dialog, Statistics Provider section, where you will find the 'Override coin algorithm' setting that can be used if needed.

CoinGecko provides some coin details like exchange rate but they lack coin properties like Difficulty and more that is required by Awesome Miner to fully calculate the profitability.

Patrik,

When I go to Options/Coins, RVN is listed twice.

Same on the Coins tab and one is showing Algo as X16r and the other instance is showing it as X16rv2.

I can hide the RVN entry associated with the X16r algo, but apparently the Exchange Balance feature is still pulling from the wrong entry despite being "hidden".

Under Statistics Providers I added an entry that maps RVN from X16r to X16rv2, but that still doesn't do the trick on the Exchange balance tab.

Is there a way to just permanently delete the outdated RVN coin entry?

I got 3 rigs with 1060 3GB cards in them (8 + 8 +7).  They have been turned down for 6+ months now.  Should have sold them back then but the thought of putting 23 GPUs back in their original boxes and shipping them one by one seems like a lot of headache.  I started the rigs back up the other day just to see what they would do.  The 8 GPU ones did about $2.60 per day and after power, about $1.35.  The 7 GPU rig was at $1.23 net per day.  So I shut them back down.  This was on RVN.

16 of them are EVGA and 7 are Zotac.  If anyone is interested, I'll let them go for cheap, like WELL under 100 bucks a pop.
69  Alternate cryptocurrencies / Mining (Altcoins) / Re: Still mining burst? on: May 31, 2019, 12:27:44 AM
I used to mine it quite heavily with about 400 TB.  Still holding about 300k of Burst hoping that one day it will bounce back at least a little.

I re purposed some of the drives for media storage (large RAID 60 array), and the rest of the drives are still sitting in my racks in Supermicro 846 chassis'.
70  Alternate cryptocurrencies / Mining (Altcoins) / Re: Hive OS - new Linux GPU mining platform on: May 30, 2019, 07:27:34 PM
If I use Awesome Miner as my primary controller and install the Remote Agent on my Hive OS rigs, do I still need to "register" the rigs in the "Hive cloud", or can I get by with just entering a rig name and password in the init.conf file and never bother managing the rig(s) from the Hive web based service?

I realize that going this route, I won't be able to update the Hive OS version on each rig as new releases come out, but since Awesome Miner takes care of keeping the mining software updated, this is less of an issue I would think.  So whenever a new Hive OS image comes out, that would be when I would update the rigs and of course I can run the nvidia-driver-update command as explained in the previous post to keep the video drivers current.

Thoughts?

Hi,

With fan control, is the a fan/temperature curve you are referring to here? For example that you define 50C -> 40% fan, 60C -> 65% fan, 70C -> 87% fan and so on?

Correct.  I set a max temp and the fans will speed us as much as they need to in order to not exceed the max temp.

Installing Remote Agent on HiveOS should work fine, I think there are a number of users running this combination and would probably be my recommendation if you want to get started fast. Did you get any specific error messages?

It has been a while since I tried HiveOS and I don't recall the exact error.  Might have since been resolved.  That said, with more than 3 miners, there is a monthly cost per rig.  nvOC is free (the version I run).  I run the Premium Edition of AM, and I'd rather not have to pay for another mining platform on top of what I already have.  I'll probably just stick with Win10 on my rigs, controlled by AM, although maintenance can be a pain sometimes. 

Quote
The automatic download feature is currently favoring the CUDA10 miners in most cases. Although you manually can point to a different version, I do have plans to make it easier to make this selection in Awesome Miner. The goal is to be able to say that you favor CUDA 9.2 and then Awesome Miner will automatically download those versions where available.

That would be an awesome feature!  (pun intended, lol)

There are currently no plans to have a complete mining OS in the near future.

Understood.

Hi Patrik,

What linux OS do you recommend for the linux remote agent?

I have been running nvOC 19-2 which is a free and has easily configurable GPU power and clocks, as well as excellent fan control.

I tried a plain install of Ubuntu, but lost all the neat GPU control features of nvOC, but did get current CUDA 10 and latest drivers.

I also got a few rigs running HIVE, but I have not had much luck getting the remote agent installed on those.

Main issue I have with nvOC, is that I'm on CUDA 9.2.148, and this don't support a lot of the recent miners which are all expecting version 10.

Are there plans for the Linux version of remote agent to come with its own linux distro at some point?
73  Alternate cryptocurrencies / Mining (Altcoins) / Re: Tesla PowerWall 2 + 50 RTX 2080Ti GPUs on: March 27, 2019, 04:24:05 PM
As long as I produce as much as I consume during the course of a month, I'm only paying the power company $32/month for the base meter charge.

So if I consume say 200 kWh a day (which would be a constant draw of 8,333 Watts, enough to power 90 1660Tis 24/7), then my monthly power bill would only be $32 and I would not have to mess with batteries and their associated maintenance cost.  Of course in order to keep the power bill at $32/month, I would also need to produce an average of 200 kWh per day.  On cloudy days and during the winter I would produce less, so during months where that was the case, I'll have to pay the shortage at a rate of $0.12.

Still, if my average production is only say 100 kWh, I would have to pay the power company for the other 100 kWh, and my net kWh rate would be $0.06 which, while not free, it still pretty good.

My long term plan is to continue to add solar panels that are grid tied, until I reach a point where I can leave all my rigs running 24/7 and only pay the power company $32/month since I will produce as much as I consume.  If I turn on all my rigs and ASICs, I draw 20,000 watts, which is 480 kWh a day.  At $0.12 per kWh, that works out to about $58/day, or about $1,730/month.  I was doing that for many months back in the 2nd half of 2017 and the beginning of 2018.  It was not a problem since I was earning as much as $500/day and the power cost only represented a little more than 10% of that.

Fortunately solar panels continue to drop in price.  Right now I can get 360 Watt 72 cell panels for $170 each, which is $0.47 per watt.  In quantity, the cost goes down to about $150 a panel, or $0.42 per watt.

String inverters run about $0.10 per watt.  Racking is about $0.20 per watt, so the grand total comes to around $0.75 per watt.  So a 100,000 watt system would cost about $75,000 in material if you do all the installation work yourself.

Once you start getting past 50,000 watts or so, you are going to run into issues with a residential grid tied system unless you ensure you always have enough miners running to keep the power you push back into the grid below, say 20,000 watts.  I did have the POCO upgrade my transformer from a 25 kW unit to a 50 kW unit last year, so I'm good for now, but as I expand towards a 100 kW system there will be trouble if my Internet connection went down for example and all my rigs went idle.  But I'll worry about those issues when the times come.  Smiley
74  Alternate cryptocurrencies / Mining (Altcoins) / Re: Tesla PowerWall 2 + 50 RTX 2080Ti GPUs on: March 27, 2019, 01:03:04 PM
PowerWall 2 specs are as follows:

Usable Capacity: 13.5 kWh
Continuous discharge rate: 5 kW

So if you set the 1660Ti to draw 90 Watts, you can power about 55 of them from a PowerWall 2.  So that's about 7 rigs with 7 or 8 GPUs each.

Keep in mind that after 2.7 hours, you have completely drained the PowerWall 2 module since the capacity is only 13.5 kWh.

A single 1660Ti will draw 2.16 kWh a day (90 Watts * 24 hours), so if you are looking for how many 1660Ti's a PowerWall 2 can keep running for 24 hours, that comes to 6.25, or a single rig with 6 GPUs.

I'll say it again, using any type of off grid battery system for powering mining rigs is a really bad idea except for a tiny experimental setup.  Once you get into needing 100's of kWh a day to power your mining operation, a grid tied system makes much more sense.

Yesterday my 128 panel array produced 183.4 kWh and the peak output was around 26 kW from around 1pm to 2pm.  If I was to use PowerWall 2's, I would have needed 14 of them to store that energy.  Instead, I just pumped it all into the grid and now have 183.4 kWh of credit with the power company that I can pull back out at my leisure.  So no upfront cost for PowerWall modules, and no worries about maintenance down the road.
75  Alternate cryptocurrencies / Mining (Altcoins) / Re: Tesla PowerWall 2 + 50 RTX 2080Ti GPUs on: March 20, 2019, 12:40:49 PM
Uh, 150 solar panels @ say 300w each will generate 45,000 Watts at noon on a sunny day during the summer.  So during that brief moment each day (in the summer months only), you can power 225 GPUs that consume 200 Watts each.

So unless you farm is floating in space with sun 24/7, you will only see a fraction of that power on an annual basis.

I currently have 128 panels with a total output of about 34,000 Watts at noon on a sunny day during the summer.  Last month I generated a total of 2,151 kWh from this array.  There were 28 days in February, so that works out to an average production of 77 kWh per day, or 3,200 Watts per hour.  That in turn translates into 16 GPUs @ 200 Watts.

During March, I have had a few days where I generated 175 kWh, which translates to around 7,300 Watts on a 24 hour average, or enough to power 36 200W GPUs.

Not sure why you want to go off grid.  It is MUCH more economical to be grid tied, especially if your POCO offers net metering.
76  Alternate cryptocurrencies / Mining (Altcoins) / Re: 8th Alt coin thread. Or what to do now that asics are all over the place. on: March 05, 2019, 12:20:14 PM
When you guys sell rigs, do you typically box the GPU's back up and sell them individually, or do you sell the rigs whole?

I got 3x 1060 3GB rigs that I will be shutting down permanently soon.  2 of them have 8 GPUs and the 3rd one has 7.  It would be much easier to do 3 transactions instead of 23, but I have a feeling I would take a big loss selling the rigs whole vs. individual cards.

With patience, I should be able to sell each GPU for $100-110, but I doubt anyone would pay ~ $1k for a 8x 1060 3GB rig (with mobo, , CPU, PSU, etc).  Besides, by selling only the GPU's, I'd still have the base system for loading up with new 7nm GPU's in a few years, should mining become a thing again.

You are never going to ROI. Sorry to tell you. Prices are going to be flat if not worse for about 2-5 years. And i expect prices to go even lower, ETH below 50 and never pull back. Watch my comments in this forum. I was one of the first here to say i was stopping my machines. 7 months later ETH network hashrates have reduced from 270.000Gh/s to no more than 145.000Gh/s, or even lower.

Considering the amount of equipment you have 23$ a day makes 700$ a month at best of profit. Your equipment seems to be very expensive. if i were you, i would be very worried about the future, because i'm sure you invested a lot on mining and the situation is not good for you.

While I don't quite share your dire outlook that prices will be flat or worse for 205 years, I do think they will be flat until 2021ish.  I purchase the solar system before I got into mining, and once I started mining, I expanded it from a 20 kW system to a 35 kW one.  My cost was about $1 per kW since I did all the work myself.

As for the mining equipment, it mostly RIO'ed before the market tanked in early spring last year as I purchased most of it back in the summer of 2017 and enjoyed the great returns of late 2017 and early 2018.

I have:

25x 1080Ti
14x 1070Ti
16x 1070
23x 1060 3GB

The 1060 3GB cards are mining BEAM under Linux and earning about $3/day after power.  That works out to about $0.13 per card, so barely worth even running them.  The higher end cards do somewhat better on GRIN, but it's value has started to slide, hence the reason I'm converting to BTC as I go.

As soon as spring gets here, I'll be selling the 1060's for sure although it will be a real pain to sell, package and ship them individually.  I do have original boxes for just about everything I have, including the shipping boxes from when I purchased them, but it is still going to suck.  The alternative is to just shut the rigs down and wait for better times, but I'm pretty sure 3GB cards will not be able to mine anything by then.  1060 3GB cards are still selling for $120 individually it seems, so it is still worth the effort I suppose to get rid of them while they still have some value.

I also have 5x Z9 mini's, 3x S9 13.5's and 2x L3+ ASICs.  They are all just sitting on the shelf now gathering dust.  The Z9's and S9's ROI'ed a long time ago.  I'm torn between selling the ASICs vs. just running them on when I have excess power to burn (I'm technically not allowed to put more than 20 kW back into the grid, so I use my rigs as "dummy loads" when I can exceed that limit by as much as 15 kW.)

Another "free energy" alternative I'm looking into is harnessing a river I have running through my property for power generation.  According to the usgs.gov charts, it flows about 100 ft3/s, which is PLENTY for me to generate whatever power I want.  Problem is that I don't have much drop, so I would need to dam it up at least 3 or 4 feet in order to deploy a low head turbine type generator.  While the ~750ft of properly line I have against this river is completely secluded (other side is as well), Virginia has pretty strict laws against man made dams on on rivers on the count of fish migrations, etc.  Still researching the possibility of diverting a portion of the flow for power generating purposes.  If I could get, say 10kW of 24/7 "free power", that would be pretty sweet, but realistically, expanding the solar farm is probably more realistic and cost effective.  Sorry for getting way off topic.  Smiley

As someone mentioned, mining during the cold months in the US does make things looks slightly less bad, as does having solar.  I track my consumption and production very closely.

Here's a snipped from my tracking spreadsheet:

My power cost is $0.1215, which is about average I think.  And at that cost, my net profit per day is a paltry $11.59 per day.

However, when you take into consideration the reduced effective rate the solar adds, the daily profit increases to an average of $18.36.  So ~$18/day plus free heat isn't THAT bad.

My rigs consume right around 255 kWh a day, and on a sunny day in February, the best I have managed is to generate 169 kWh.  My profit that day was $23.51.

So yeah, margins are very slim, but solar can improve the picture.  The above numbers completely ignore the cost of the mining equipment and the cost of the solar, which is my case is paid for.  If you include the cost of those, the ROI would be very long.  And come summer, unless things change, I'll probably only mine during during sunny days.

Yeah but we get credits from NJ that help so it evens out.

All the bad air from all the coal fired power plants running from Illinois to PA is the reason NJ does this...

Yikes, yeah that looks pretty bad!

Ok, so the credits are for the kWh's you produce, not just the up front cost of the panel themselves?  That would definitely make it more even.

Are you doing anything with SREC trading?  Looks like NJ has a good market for those as well.

I got an account with these guys:

Very cool project Phil!

Makes my 128 panel 35kWh setup look like a toy setup, lol.  I have had a few days here in February where I have generated 150 kWh in a day though, so I'm not complaining.

I couldn't help but note that you stated you pay the power company $0.13 per kWh but they only credit you back $0.04 for each kWh you put back into the grid.  Did I read that right?

Reason I ask is that here in Virginia, I have net metering and I pay $0.12 per kWh 24/7 year round, and when I produce more than I use, the power company credits me at the exact same rate ($0.12 per kWh).  Now I can't "cash out" it is just a bank of kWh that accumulates on my account, but since I consume more than I put back in the grid, generally speaking, that is not a concern.

So you have no option to just build up a bank of kWh with the power company during the day that you can then burn through at night?  I guess you would need enough mining equipment to make the 2 equal out.  Just seems unfair that they don't credit you at the same rate they charge you.  At least the $0.08 kWh deal to your neighbors make it a little but better.

But overall, you seem to have it all planned out and your business model is sound, it could just have been even better I think, if the power company credited you the kWh at 1:1.
