I don't see why I would be delusional, it's just a questions. You've got asic machines below 2000$ but from what i read you make a couple of bucks a day on BTC. With my GPU rig, I make around 12-13$ / day (ETH and sometimes ZEC).

Hello Zarados,

I've been down that road a couple of months ago and I ended up building a 10 GTX 1060 rig for a little bit more than your budget.

Why GTX 1060 ? Simply because it gives the best ROI, it can produce 23MH/s (with Samsung memory) for 200$ or less. It's very power efficient, I have limited mines to 75W each and the whole rig takes 850W from the wall (all included: motherboard, ssd, gpu, ...)

GPU:
eVGA GTX 1060 (199$)

Motherboard:
Asrock Mining motherboard 13PCIe (141.95$)

SSD:
120Gb SSD (59.99$)
If you do not intend to sync the blockchain, you can take a smaller one.

Memory:
8 Gb memory (59$)
You can take a cheap one here, it's not so important unless you want to run many applications at the same time

CPU:
Low end Celeron cpu (39$)
Unless you want to do something else than mining, you don't need a powerful cpu

PSU:
I decided to take a server PSU to provide power and reliability. I took one from parallel miners:
2400W psu (119$)
2400W is overkill for that price it's unbeatable

PSU:
I took a small and cheap PSU for the motherboard
EVGA 450W PSU (37.89$)
It's a bronze one, you can take a better one if your budget affords it

PCIe risers:
I took some cheap ones from aliexpress:
PCIe risers (30$ for 6, 60$ for 12)
I bought extra cables to connect those risers directly to the server PSU

Total for a 10 GPU Rig:
2447.83$
You can probably go a little bit below by chosing a cheaper motherboard, memory and SSD but I would keep the amount of GPU because that's how you're going to make the money.


Important remarks:
- I did not have to buy a keyboard, mouse or screen, I already had spares
- I'm using Ubuntu, it's free
- you need to have Samsung memory but you can probably use Amazon's return policy (I did it with Amazon France)
- how you put everything together is up to you. I use aluminium bars but I've seen rigs made of wine racks, shoe racks, ...
- you need to include power costs in your ROI calculation. I have solar power.

And the result is the following:


I currently make between 12 and 13$ / day but it will go down as soon as the difficulty rises.

Enjoy!

did you check your logs ? Seems like an OC issue. I optimized my cards one by one because if you push them all at the same level you'll never understand which one is causing the issue. It takes more time but at least you can pinpoint the problem.

I'm not familiar with ASIC but how do you calculate the profitability? I thought that ASIC was cheaper to buy but was less profitable than GPU mining.

bitfort: you're right, I have added it to the original thread, thanks for pointing out!

makomako: you've got a point. I did the testing at max 1 day of interval (sometimes within the same day) so difficulty was most likely different but probably not so much. I should perhaps try a 50/50 approach to rule any external factors.

Thanks. Why wouldn't it be exact? I simply described what I experienced.

Hello all,

I started mining in july this year and I have been playing with many different pools to see if there was any difference.

I mainly mined on the following mining pools with EU servers. They are all using 1% fee with different rewarding schemes.

Nanopool
+ I achieved one of the highest average hashrate with nanopool (up to 235Mh/s average per day)
+ nice interface with view on current and past performance
+ low threshold payout
- sometimes big discrepancies between miner and their dashboard

Dwarfpool
+ higher than average hashrate, better than Nanopools in the last couple of weeks
+ simple and straighforward
+ low threshold payout
- very basic dashboard, difficult to read graphs

Ethpool
+ predictable solo mining
+ nice and practical interface
- rewards are going to big mining farms
- need more time for payouts

NiceHash
+ Different concept, you sell your mining power instead of mining coins, you get rewards in BTC
+ Good overview on current and past performance
+ No need for a wallet in each currency
+ Manage to get decent money out of it (comparable or slightly higher than normal pools)
- fluctuating performance, hashrate sometimes go really down while I did not see this in my miner
- difficult to predict as it's not directly linked to the currency you are mining, someone needs to buy your miner power

Minergate
+ nice and easy interface
+ many currencies available
+ multicurrency client (Windows AND Linux)
+ no need for a wallet in each currency
- suggested currency to mine is not the most profitable one (I was always suggested to mine XMR)
- hashrate between miner and minergate dashboard never match and what they display on their site is always lower than what you see in your miner
- no view on past hours/days

Any other pool worth mentionning?

I now primarily use Nanopool and Dwarfpool but I have 2 questions:
- what would explain that my average hashrate on dwarfpool is higher?
- when I mine on Dwarfpool, my miner (genoil ethminer) crashes once a day (ends up in a CUDA error) while with exact same configuration I don't have that issue with Nanopools

Thanks!

Thanks Pendra & Shavill, that means that the GTX 1060 still have a nice future and price is more or less back to "normal".

I forgot to add temps. I'm between 47 and 55°C with nothing else than the factory fan.

I also see an increase. I'm around 12$ day now with 230MH/s on average

Pendra37: how do you calculate the dag limit? I have only 3Gb cards and I know from the start that there will be an end but when is more difficult to predict. Will POS allow 3Gb cards to continue working?
Power meter in the wall indicates 850-900W for the whole rig (motheboard, gpu, psu, ssd, cpu,...)

I'm using 10 GTX 1060 in my rig running under Ubuntu 16.04



I get an average slightly above 230Mh/s

I have cards from different manufacturers (EVGA and MSI) so settings may vary.
Usually max power 75W, core clock -200, memory between +1100 and +1600
I have Samsung memory on all cards.

EVGA model is a bargain:
EVGA single fan

Models from MSI:
MSI double fan / armor
MSI Single fan

Power meter in the wall indicates 850-900W for the whole rig (motheboard, gpu, psu, ssd, cpu,...)

Have you tried to limit the power ? More power = more temperature = more trouble.

try mining with one gpu to start with, it might be a hardware issue. By testing your cards one by one, you should be able to isolate the issue.
Underpowering could also be the issue.

What about DMD ? According to whattomine.com, profit seems high but I haven't tried yet.

I bought this one: Asrock H110 (I had bought it around 200$, it's much cheaper now )
It's indeed a 13 PCI slot model, I didn't count the PCI 16x, that's why I thought it was a 12 PCI model. I don't about the split between Nvidia and AMD, I have 10x GTX 1060 installed and they're all working fine. I use Ubuntu 16.04.

Thanks, I'll try that.

I have an ASrock BTC with 12 PCI slots, I'm only using 10 of them.

Hello all,

I'm new in here. I used to mine ETH but profit has gone down so now I'm trying out Zcash.

Here are stats from my rig:

GPU   Temp   Power   Speed   Efficiency   Accepted   Rejected
GeForce GTX 1060 3GB   51 C   66 W   237 Sol/s   3.59 Sol/W   36   0

GeForce GTX 1060 3GB   49 C   72 W   258 Sol/s   3.58 Sol/W   45   0


I have reduced power to 75W for all cards. Efficiency looks ok but I haven't managed to increase sol/s by a significant amount unless I remove the power limit.
If I don't use power limit, sol/s go up to around 3000 but power consumption goes to 1200W.

I have tried to play with memory frequency but the effect is close to nothing. When I was mining ETH, memory frequency had a direct impact on performance, ZEC seems different.

Thanks
