Any idea where to start ?

Nowadays $384 target price for that GPU is becoming hard to find ! it's running ~500 USD for same gpu on amazon !

Hello,

I'm designing a new service where i'm offering payment with any token, is this possible to manage through one geth wallet ? how can it be possible ?

Thanks !

All my rigs are running on wifi with a dedicated router and network for them, this is cheaper and cleaner than managing cables and switches.

Okay definitely lost on my saturday ... i've forgot to mod my bios !

Now am back to my 29 MH/s

I'm trying to overclock my new card using ohgodatool and i'm only getting 17MH/s for eth mining (16 MH/s before overclocking).

Here's my config:

• Card: https://www.msi.com/Graphics-card/Radeon-RX-580-ARMOR-8G-OC.html
• Ubuntu 16.04.3 LTS - 4.13.0-26-generic
• Claymore v10.3
• amdgpu-pro-17.40-483984
• ohgodatool overclocking: ohgodatool -i 1 --mem-state -1 --mem-clock 2100

What's going wrong there ? i guess this card is even capable of 25MH/s with no overclocking, why is it going down to 16-17 MH/s ?

I have swapped out ethos-distro, although it is a very good packed OS to start mining including all the tools you need in one place and the ability to manage everything remotely, i've encountered an issue where no support were given from the ethos chat, the issue were simple: ethos does not recognize any GPU on some rigs, but claymore is running with no problem when launched manually from ethos-distro ...

Not having a reliable support behind ethos-distro were a break point, decided to go build my own linux box with overclock/undervolt and a set of useful miners.

EthOs offered me a cool way to query their API for monitoring data, after going to Claymore on Linux i've discovered there's no remote monitoring API for it, so built my own API on top of Claymore and here's the result:



Updates:

• Some dust started to accumulate, now i have a planing for dust removal every 1 month, have to find some local help,
• Controlling 1000Watt rigs through a 10A (220V) relay board appeared to be a bad idea, the relays fried under current pressure, i'm looking for another solution, maybe static relays instead of mechanical ones.

Hey there !

I have one rig (A) with 1600 Watt PSU and only pulling 850 Watt from the wall with 6 GPUs running, another rig (B) with 1000 Watt PSU and pulling 1010 Watts from the wall with 6 GPUs running.

Can i disconnect power supply of 2 GPUs from rig B and plug them on rig A's PSU ? i will keep them running on on rig B's mobo (connected to mobo through powered risers from rig B PSU).

Is this doable ? am i risking to fry something ?

Checkout my setup with homemade smart plugs that can restart any rig anytime, here: https://bitcointalk.org/index.php?topic=2663409.msg27162143#msg27162143

I've made scripts to reboot the rig, but most of the times the OS were freezing and does not respond to a reboot order.

So finally fixed my issue here: https://bitcointalk.org/index.php?topic=2663409.msg27162143#msg27162143

Hello every body !

I've gone building my mining garage, now with 9 rigs x6 GPUs and expanding to to 40 rigs before mid February, every rig's consuming ~1000 Watt, so 40x1000 Watt is the maximum i can pull from the wall at this moment.

My target is being able to run an autonomous mining garage with a very minimum effort for on-site intervention, this garage is running 600km from my home, that's for getting colder weather (~3°C now and a max of 26°C in summer), so definitely on-site management will be a headache.

I'm considering the following considerations:

• All rigs are running Linux, i dont trust a Windows OS to be reliable for an industrial scale,
• Using Claymore or Ethminer,
• All my rigs must be reachable through a VPN connection, using SSH console,
• No AC must be used,
• Any air sucking fan, or any other fans must not work 24/7, they must be running only when a temperature threshold is met,

And from my background experience where i'm an IT architect and being passionate of software building, this garage is an awesome playground for me.

This is my in-house rig build:


It's an aluminium rig with a wood plate to host the mobo and the psu.

Temperature monitoring and fan control is done through this piece:


I've built 4 of it, a smart power strip embedding:

• Power relays to control power on 8 sockets (on/off)
• Energy sensors to monitor Volt/Current/Watt consumption on every socket
• A Raspberry Pi system that can make all the smart things with the strip

And at the end, monitoring all of this through a monitoring system, using Zabbix, here's the kind of dashboard i'm getting:


The monitoring system pushes me emails for any thing going wrong and can even make automatic actions like restarting or even shutting down some systems.

Hopefully i'll not have to travel 600km every weekend

Am sharing this experience for you so you can better your farm implementations, and do not hesitate to ask for any help !

J'habite au Liban et je penses à ouvrir une mine au quebec, est ce compliqué pour un touriste de louer un appart au quebec ? mon plan est de mettre en place mes mineurs, les brancher et les administrer à distance, je quitterais le quebec pour revenir au Liban.

And customs ? how will you deal with them for electronic parts ? cars ?? dont tell me your country does not have regulation on purchasing cars ...

You say you're gonna pay in BTC ----once the item is sold---- in your country, this means the good owner will rely on you for receiving, clearing the customs, reselling with a margin, with trust in every step ?

And what about customs in Algeria ? how will you manage this ?

In my case the card is off on Win10 with no mining activity at all.

Even when i have it as unique plugged card to the board, it's still not visible on Win10 and run on Ethos for some time then crashes.

When i plug it to another PCIe port the issue is fixed, can i confirm a malfunctioning PCIe port ? is it normal it run only on Linux (ethos) and for a random time ?

And PSU is a Corsair HX1000W ...

I'm running Ethos with a 6 GPU rig (RX 580 and Mobo is H81 Pro BTC R2.0).

After overclocking/undervolting, i get a satisfying hashrate at ~170 MH/s for 950 Watts (from the wall), GPUs are running under ~55°C temperature.

My actual problem is am getting the 6th GPU to go off randomly after a couple of hours, in claymore i get the following error:


I've gone investigating the issue, here's my results:

• Changed the riser, the cables and the power cable of the riser: still same issue
• On Win10, the system could not detect the 6th GPU ! i can only see 5 GPUs just on system startup and not after running couple of hours of mining like on Ethos
• Cleared CMOS, same result
• Undervolted and underclocked down to 24 MH/s, still same result

Any idea guys ?

Here's my actual testing results: https://docs.google.com/spreadsheets/d/1gYGcipErSIAVZE6D7dKoBn-EqzU_-kKrU-rT63Hz8QE/edit?usp=sharing


I'm running the tests now, so any suggestions are very welcomed

And what's the perfect balance (Watt / Hash) ?

I'm doing 31 Mh/s with these cards while pulling 150 Watts per card and that's too much (ethos / claymore) ...

I've seen guys reporting 75 to 90 Watts per card and i've never succeeded to even gain a 1W down.

What's the trick to undervolt this card ?
