We got a great response from the 6 GPU Mining Rig build series we did and decided we’ll do another. This time, we’re gunning for a 19 GPU Ethereum Mining Rig, pushing AMD’s B250 Mining Expert motherboard to it’s limit. We’re calling it an Ethereum mining rig because we’re bullish on Ethereum. But, of course, the rig will be able to mine the usual suspects that regularly top the profitability sheet including:
- Ethereum (ETH)
- Ethereum Classic (ETC)
- HUSH (HUSH)
- Feathercoin (FTC)
- MONAcoin (MONA)
- Zcash (ZEC)
- Zencash (ZEN)
As usual, we mine what is most profitable and convert it into what we want. As things stand today, however, it’s more profitable to just straight-up mine Ethereum as opposed to converting something else. Like most things, that too, will change in time.
Mining-capable GPUs are hard to come by once again. While price-wise GTX 1070 cards are usually the better buy (they pay off faster and mine at a very similar rate) we tripped across some EVGA GTX 1070 Ti cards that were priced right.
19 GPU Mining Rig Build Sheet
Here’s our shopping list for the 19 GPU B250 Mining Expert Build:
- (1x) ASUS B250 Mining Expert Motherboard
- (13x) EVGA GeForce GTX 1070 Ti FTW2 Gaming (any Nvidia 1070s or 1080s will do)
- (6x) Build-compatible GPUs – TBD
- (4x) MintCell 6-Pack PCIe 6-Pin 16x to 1x Powered Riser Adapter (6-pin PCI-e)
- (1x) Patriot Memory Viper Elite Series DDR4 4GB 2133MHz (any desktop DDR4 will do)
- (1x) Intel BX80677G3930 7th Generation Celeron Desktop Processor (any 1151 socket will do)
- (1x) KingSpec 128GB SSD (any 60+ GB SSD will do)
Missing Mining Rig Parts
What’s missing? We are only specifying 13 1070 Tis. Why? Everything we’ve read says that you can only get 13 to run and then you round out the board with 6 other cards. We’ll keep you posted when we’ve selected them. We’re also still deciding what we want to do for the PSUs (or should I say, we’re shopping around for good deals on PSUs). We may go with server PSUs with breakout boards or may stay off-the-shelf. And, there are some parts we have kicking around so we didn’t mention anything beyond the core components (Y-splitters, etc.).
We’ll do a complete writeup and include the final build list then. This one isn’t going to be as straightforward. There’s fussiness getting all 19 cards up, and we might try a new OS this round. We’ve been running Windows 10 historically, but certainly aren’t tied to it.
Stay tuned. Almost all of the components have arrived or are en route. It looks like a couple of pieces may hold us up a bit.
Are you running a 19 GPU Mining Rig with the B250 Mining Expert? Let us know below! We’ll take all the advice we can get!
Did that work?
I also have B250 Mining Expert with MSi 1070 Ti, and its giving me headache. It’s been two days, tried everything but it’s giving me error on Claymore.
and then it restarts
Any suggestions? I’m kinda pissed.
I had the same problem. Flashing the Motherboard BIOS to the newest version (v10006) solved it for me.
Let me know how it went for you.
hi, any progress with server psu and this board? thanks
Unfortunately no. We can’t get GPUs. Did you get a build up and running?
In which slots did you put your 13 1070s? I am planning to run this with 10 but I would like to know if you can go over the limit of 8 that the manual states for Nvidia only and if so, which slots work. I was planning to put the 6 on a 1200W PSU and 5 on a 1000W. (on channels A and B). Advice?
@Chuck – we never even got to build it. Victims of the GPU shortage. I think we’ll just do a raffle and give it away. Hope your build comes along and sorry we couldn’t give you any usable advice.
Hello your post has helped me alot in building my rig. Did u use windows or linux?
Thanks, Thomas! All of the rigs we are running are on Windows 10.
How do you calculate your ROI? Do you include income taxes and the sorts (when selling coins for real money)? I would be genuinly interested in your calculations and what your thought process is when planning such a big endeavor.
Only 0.4% of all miners pay taxes…
13 AMD GPU’s only, system does not turn on as soon as I put in the 14th AMD GPU. Will be testing with Nividia soon with the 13 AMD.
Cannot maintain consistent hashrate (with modded bios), need to do a power-cycle to get back to the original hashrate.
I tested GTX 1060 6GB with 13 AMD RX 560’s and it does not post.
My understanding is that the 6x nvidia cards MUST be mining edition aka P104/P106 cards.
When will Asus release a BIOS update that will enable full 19 card configurations?
Asus released a new BIOS just a few days ago.
I hope I could help
I run a couple 13 GPU rigs with this motherboard. I originally intended to do 19 GPU’s but you definitely need atleast 6x mining edition P104/P106 cards.
That being said, the mobo is awesome 😀 I have 13x RX 560’s hooked up to a single EVGA 1300 G2 power supply.
Eth: 201 MH – 790 watts (at the wall)
Cryptonight7: 6200 H/S – 665 watts (at the wall)
Ravencoin: 36.5 MH – 650(low) – 950(high) watts (at the wall)
In my opinion, when talking just straight Ethereum mining performance… not many cards can beat the power vs hashrate vs cost that you can get with the 560’s… and the fact that you can have 13 of them on a single PSU because they often don’t have PCI-E power connectors… is just amazing. I will say though, certain 560’s don’t perform the same as others.
