Hey fellow miners.

I have decided to invest around 200k to build a mining farm (I have really cheap electricity). I am having a hard time finding good and in-stock equipment these days. Especially GPUs and motherboards. What are your preferred mining GPUs for late 2020? I was thinking 580 or 570 8GBs, but I could not get any seller with that amount of stock.

What would your recommendation be? Are there any other new mining specific GPUs out there, something similar to p104-100 for example.

Hello fellow miners!

I have found out this website https://www.wheretomine.com/. I thought about sharing it with you. What do you think about it? I like the fact that someone actually started that project and that it can help you to choose the best mining software.

My partner and I have recently closed or mining farm due to not being profitable anymore. Long story short - electricity price rised for around 30% - 40% in Slovenia in the past 2 years, we have had an old contract for two years which had eletricity price at 0.07€/kWh.

We are looking for a buyer who is interested in 75 rigs(6 slot and 12 slot motherboards).
We have been mining Raven and Ethereum most of the time.

Each rig is made from:
- 6x or 12x Zotac P104-100 flashed to 8 GB
- GA D3A motherboard
- 4GB ram
- Intel celeron G3900
- 6x or 12x USB riser
- 1600w 1st Player PSU
- 16GB SanDisk USB

We also add a lot of spare hardware like:
- 50x USB risers
- 10x 1600w PSU
- Electricity extensions
- LAN cables
- Bounch of 180cm x 90cm x 40cm racks that were used for rigs
- Smart swithces and normal switches

Price for one rig (6x GPU) is 1300€, if you buy all, we can go down to 1200€. That is the final price, which is fair for both parties.

If you have any questions leave a comment below or send me a PM.

I am facing a weird issue where all my back USB ports are dead. There has been a power loss and after that, the USB ports are not working anymore. The DVI output is working.

What have I tried:
- Reset BIOS -> did not help
- I used different ports -> did not help
- I tried with keyboard and USB -> still not working
- I luckily have a spare PSU to try with -> did not help

I am waiting for PS/2-USB adapter so I will be hopefully able to use my PC.

Anyone had a similar issue before?

Hey guys,

apparently, Bitmain released a new firmware that makes Antminer Z9 work with Nicehash. I was just considering buying one and would like to know if it actually works.

Can someone confirm that Z9 works normally on NH now?

Hey guys, does anyone know how to calculate raven mining profitability based on block time, block reward, difficulty, and hashrate without whattomine or any other calculators?

I tried this one that I found online, but apparently, it does not match. (block reward * 24.0 * 3600.0 /(difficulty * 2³² / hashrate))*exchange rate

Any help will be much appreciated.

Hey fellow miners!

I was googling CPU hashrates and I could not find any hashrates for CryptonightR. So it came to my mind that we could post our hashrates on this thread and eventually we should have a decent CPU hashrate database for future reference.

I will start with my AMD Ryzen 3 1300X, I also included CNHeavy and CryptonightV8 since I used Nicehash for benchmarking.

CryptonightHeavy: 20.6 H/s
Cryptonightv8: 55 H/s
CryptonightR: 56 H/s

As mentioned, does anyone run similar setup at home or in the office?

Can you attach a picture? How do you manage heat problem? Any advice?

Hello guys,

I have a problem running 3x RX 570 and 2x RX 480 together, when I run sgminer via Nicehash it crashes my rig. If i run only 1x 480 and 3x 570 it works normally.

i have tried running each card by itself and it works normally. I have 1000W Chieftec Navitas PSU. I have tried changing raisers with new ones and reinstall of drivers and all the basic stuff.

I have been running this kind of setup for few weeks and it has been working normally.

Did anyone had any similar problem?

Thank you for your time!

Hey, I have had problems with my rig for weeks now. I have asrock btc r2.0 mobo with 3x 1060 3gb and 3x p106-100 mining edition gpu.

First problem is that windows recognizes all gpu's, but when I run nicehash with, for example, EWBF miner it says "thread exited with code 30", then I restart nicehash and EWBF works fine with 5 gpu.
After few seconds one of the gpu's Sol/s starts to drop and stops at 0, others work fine all the time(except the 6th gpu, which I am still figuring why wont work even though it is recognized in device manager.

I have tried getting new raisers, reinstalling drivers with DDU...

Any help would be appreciated!

Hey,

I have been mining with my rig for quite some time without a problem. I am using 6 Sapphire rx 570 4gb, Asrock H81 pro btc mobo and 2x 700w psu.
Now when I start mining my rig keeps restarting, I am mining with claymore on dwarfpool and now on nicehash via claymoreminer. I have tried mining with Nicehash.

I figured out that when I change settigns in bat file in claymore miner and then start mining, computer restarts and when it turns back on the settings in bat file are same as before. I have tried saving bat file and do the manual restart. It still didn't save settings.

Anyone with similar problems?

I have problems with my mining rig. I have been searching previous posts and googling it but coudn't find a solution.

I have mining rig with 3x p106-100 and 3x GTX 1060 3gb. With H81 Pro BTC R2.0 and 550w PSU which has 2x P106-100 + MOBO connected to it and 700w which has other 4 GPUs connected to it.

I get the following error:

I tried switching the psu back and forth, I tried to run only 1 gpu which was not working and it worked normally alone. Of course I reinstalled drivers with cleaning them with DDU before.
I swapped the raiser with second GTX 1060 and the problem wasn't gpu. It might be raiser but when I tried that raiser and one card it worked.

What should I try more? Any tip would be helpful!

[2x normaly working Asus RX 480]

Hey guys, I have unusual problem with my new out of the box Radeon RX vega 64.

My components are:

• 4gb ram
• 500gb HDD
• LC power 1650 mining
• AMD athlon II x2 260
• MSI 970A-G46 Motherboard
• 2x normaly working Asus RX 480

I am using Nicehash miner Legacy. Tried with 1.8.2xx and 1.8.3.
More or less trying to mine CryptoNight since its most profatible. Is it possible that it would work on DaggerHasihimoto?

My problem is that when I start mining rig crashes, sometimes instantly, sometimes after 5-15 minutes maybe.

I have set vent speed to almost 100% in WattMan since afterburner doesn't allow to change vent speed.
I have lowered power usage by -10 and later -15%.
I have tried setting max temp to 80°C(it worked for few minutes yet crashed anyway.) I get popup that GPU has exceed its temperature limit every few seconds. And the temperature really jumps up and down from 77°C to lets say 83°C if I have set max temp to 80°C. It can go up to 88°C if its set on 85°C.
I have tried getting 2 different power cable from the PSU in to 1 GPU only, so I eliminated problem with too less power going through one cable.
I don't know what else to do.
I have tried using another motherboard (Asrock h110).

I used latest AMD drivers 17.11.4 and 17.8.2 and even blockchain drivers, everything stays the same

I have open rig and vents blowing in below the air conditioner.


Anyone with any idea what should I try next?

I would appreciate any kind of suggestion, tip, idea that comes through your mind.

Hey guys, I bought 2 Radeon RX Vega 64. One of them works almost normal, with Temp around 80°C-86°C with fan on 48%. I tried setting vent speed manually in AMD settings which helped.
The other card had problems and I got it replaced, now the new one came and has overheat problems, even if I set vent to go higher and I set higest allowed temp to 80°C. Yet GPU stil causes problems and crashes.
The same GPU shows 8(i think so) red LED lights at power pins at top, I dont know what does that mean, the other one doesn't show the lights.

Anyone with same problems?

I have so many problems with this board. Probably just bios fucking me over all the time. I have 3x 1060 3gb and 3x p106-100 mining

Can't seem to get to work with 6gpus at the time. All 6 of them work fine separately. But when I plug them in all together I am stuck at Windows logo screen and the loading circle keeps circling.

I have tried enabling 4g decoding and then I don't even get to the windows screen. I tried switching to GEN1 and GEN2 still nothing. I did Windows 8.1/10 WHQL Support -> Enabled too.

Is there anything I am missing out? I once get them to boot with all 6, but then one GPU showed me following error: "This device cannot find enough free resources that it can use. (Code 12).

I restarted and added 4gb RAM and didn't get it up and running.

I have few rigs with asrock pro btc h81 r2.0 and didn't had a problem with them at all. Then there was a time I coudn't get any cpu for Asrock motherboard so had to buy this one..

Anyone with similar problems?

Hey guys,

I am running 6x P106-100 Gigabyte. I had problems with setting up to work with 6x at the same time, i figured out I had some raisers/psu power problems, now when I start mining with claymore, I get "cannot get temperature" error and then miner restarts and starts working with 5gpu, after some time, same happens with 1 gpu more and then it works with normally with 4gpu.

Any help would be appreciated!

Hey guys!
I am building a 6x Nvidia Gigabyte p106-100 mining rig. I use H81 PRO BTC R2.0 motherboard, 4gb ram and 1x 700w technoware psu+1x 500w technoware.

When I try to mine with 6 gpu I get "Error 15, cannot get temperature." or something like that and bunch of red errors. Then claymore restarts itself and starts working with 5gpu and continues to do so. I have tried disconnecting random GPU and then it works normal, even if I plug out 2 or 3 random GPUs one at the time it works with 5, so it shoudn't be the gpu or raiser failure?

I have tried connecting motherboard + 3 and then 4 gpus on 700w PSU, then I tried connecting motherboard +2 and then 3 GPUs on 500w PSU, still the same problem. I have added molex cable to motherboard, set GEN1, tried literally everything I could think of...

When mining I have touched GPU to see which one is cold, tried that one only and it worked normally.

I am really desperate here, any advice will be thankful!

hey guys,
I am trying to set up mining rig with 6 Nvidia Zotac 106-100. I am using H110 D3A motherboard.

I have tried updating bios, i tried every possible way with GPU raiser combination. It is not raiser or GPU problem, i think its motherboard problem. PSU shoudn't be a problem neither.

When I say pc doesnt boot, I mean that PC starts and doesn't show gigabyte logo. Afterwards monitor shows black screen with flashing cursor in left top corner. After few minutes it says to insert bootable device.

I have a lot of experiance with mining rig building, but never have seen any problems like that. Only thing that I can think of is that Zotac Gpu isn't totally compatible with h110-d3a motherboard.

I would appreciate any help.

Hello guys, I have problem setting up mining rig with 6x Nvidia p106-100. It all worked okay for about 1 months but now i get error 15 in Claymore miner. Says it can't get temperature.

When i update drivers, I can see all 6 Gpus show up nicely in device manager. When I start the miner I get red warning that miner cant get temperature then shuts down or it continues to mine with 5 GPUs.

Then I go back to device manager and disable all devices and enable them back on, one gpu shows this error:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

The specified request is not a valid operation for the target device.

Google says it could be drivers or hardware. Even though I used DDU to delete drivers and installed them couple of times. I used drivers from Gigabyte website made for P106-100. I tried drivers for GTX 1060 too still not working. I have problems with that kind errors on few other rigs too.

Can anyone help? I am willing to donate small amount of BTC to the person who finds out the solution!
