Build A Ethereum ETH Miner

Building an open-frame GPU miner. It’s finally time for an update to my popular! It’s four years later, and Ethereum mining is where it’s at for GPU miners, so that’s what I’ve focused on. I’ve kept the same format and detail level as my old guide, so if you were around back then, you’ll know what to expect. If you’re new to the world of crytocurrency mining, this guide should give even an absolute beginner all of the knowledge needed to put together an efficient Ethereum (or other GPU-minable altcoin) mining rig using readily-available consumer hardware. This guide will be broken into several parts, each focusing on a different aspect of building your first mining rig.

First, let’s take a look at what you’ll need in terms of hardware to put a respectable Ethereum miner together. Build your own Ethereum Mining Rig, part 1: Hardware Here is the list of hardware that I recommend. Don’t worry if you’re not able to get exactly what’s on this list, I provide some excellent alternatives below the table. Motherboard 1 x $180 Processor 1 x $45 Memory 1 x $40 Power Supply 1 x $260 GPUs 3+ (*see below) ~$200 each Boot Device 1 x -or- (Linux) $5 – $35 Case 1 x build your own (see bottom) -or- $30 – $200 Some explanations and alternatives for each item: Motherboard Generally, any motherboard with PCIe slots on it is suitable for mining—typically one GPU per PCIe slot. The PCIe slots don’t need to be full-length, as we can attach GPUs to 1x slots with the help of risers. With that said, there are potentially some limitations when you start to pack a large number (4+) of GPUs onto one motherboard, even if that board has enough PCIe slots to physically accommodate them.

That’s why picking a suitable motherboard is probably your biggest hardware headache if you want to run as many GPUs as possible in your rig. My top choice is currently the. It’s literally made for mining, with support for up to 19 (!) GPUs and 3 power supplies right out of the box. Even if you don’t intend to initially run more than a few GPUs, the included mining-centric diagnostic features and ability to expand later probably make the price premium over less-robust boards worth it. The is another excellent choice for mining, with support for up to 13 GPUs.

However, it currently costs about the same as Asus’s mining board, and for the money I’d rather stick with Asus. If you know that you’ll definitely stick to a single PSU and a small handful of GPUs (e.g.: the majority of us), this is a fine choice, especially if you find a deal on it.

Finally, the is also aimed at miners, and costs considerably less than the Asus and ASRock offerings. The Biostar board “only” supports 6 GPUs, but that’s likely all that the majority of us need. If price is your primary consideration, the TB250-BTC should be at the top of your list for 6 GPU rig builds. If you only want to use 3-4 GPUs in your rig, then you’ll have a much easier time. Most boards with up to four PCIe slots should accommodate a GPU in each. Keep in mind that you can use old hardware that you have sitting around—the board doesn’t have to be recent.

I dug out an old that I used four years ago for litecoin mining, and it still works fine today for up to 4 GPUs (5 is possible with some work). So it’s possible to pick up an ancient board on eBay/Craigslist for nearly nothing and mine with less than 6 video cards. CPU / Processor This one is easy: buy the cheapest CPU that works with whatever motherboard you pick. When it comes to mining, the GPUs do all the work.

Your CPU will essentially sit idle, so there is no reason to waste money on anything other than the bare minimum. All of the motherboards that I recommended based on Intel’s LGA 1151 socket, so that means the is probably the best choice. If you go with an AMD motherboard, a Sempron CPU will do nicely. Memory 4GB is fine.

Overkill really, at least for Linux. If you have an old 2GB stick (or even 1GB!) sitting around and plan to run Linux, you’re good to go. If you want to run Windows, then 4GB is probably a realistic minimum. While Ethereum mining is pretty memory-intensive, everything happens on the GPUs. System memory will be pretty much unused, so there is no reason to spend money here, especially with DDR4 prices so high. PSU / Power Supply The power supply is extremely important—don’t skimp on it!

A good, efficient PSU will keep your electricity costs to a minimum and more than pay for itself over the long run. Seasonic, EVGA, and Corsair are all generally top brand choices. The that I’ve linked may seem like overkill, but power supplies are most efficient when they’re not running near their rated maximum load. A 6 GPU rig will draw about 750 watts (assuming 6x RX 570 cards, properly optimized), which means a 1200W PSU will have sufficient headroom to perform efficiently. If you’re planning on running only 3-4 GPUs, you can save a bit of money and go for their instead. GPUs / Video Cards The top Ethereum mining choice is currently the Radeon RX 570 / RX 580 line*. The RX 570 delivers nearly the same performance as the RX 580 (within 4-7% or so) for a bit less power consumption—they’re essentially equal from an efficiency standpoint. The RX 570 is usually significantly cheaper than the 580, so generally the 570 is the best choice.

Which model to pick, though? While literally any RX 570/580 card will do, the most important thing to look for is memory speed if you want the best performance. Cards with a higher memory clock speed will generally perform a bit better while mining ETH (and can generally be overclocked more). Memory capacity isn’t really important beyond 4GB, so all other things being equal, there is no reason to shell out extra cash for the 8GB version of a card. It’s true that every GPU needs to be able to hold Ethereum’s DAG file in memory, and that file is slowly increasing in size—but it won’t surpass 4GB until late 2019 (and ETH’s will likely occur before then, anyway). With all of that said, the 8GB versions of the cards tend to have faster-clocked memory than most of the 4GB cards, so if the price difference isn’t too large, spring for whatever is the fastest.

Most of the cards fall between 1650 Mhz (6600 Mbps effective) to 2000 Mhz ( 8000 Mbps effective). The slower 1650 Mhz memory GPUs will hash at 21-23 Mh/s, and the fastest 2000 Mhz ones will do 25-28 Mh/s (both can potentially be pushed higher with BIOS mods and good luck). The best advice is usually to just pick up whichever 570/580 card you can get your hands on for the least money, as mining speed differences between brands/models are pretty small after optimization. These are $220 each as of, and I’m running mine at 28 Mh/sec without pushing them too hard. If you can still find old RX 470/480 cards on the secondary market, they’re just as good the RX 570/580 cards that replaced them. *While my guides deal with setting up and optimizing AMD’s GPUs, nVidia’s / video cards are also excellent for mining.

Generally these days I tend to recommend whichever is cheaper (and right now, that’s AMD). But if you find a deal on some GPUs, don’t hesitate to grab them—they perform just as well as AMD’s offerings, and are arguably easier to set up (just remember to install nVidia drivers instead of AMD’s if you follow the rest of!). Boot Device If you plan to run Linux, you can use pretty much anything, including a ~$5 (we’ll be using Claymore miner, which doesn’t write Ethereum’s DAG file to disk, so we don’t need to worry about wearing a USB stick out due to constantly writing to it, like with the stock ethminer).

With that said, SSDs are pretty cheap nowadays and it might be nice to have one in case you want to try Windows at some point. If you plan to run Windows, then a cheap is your best bet.

If you have an old mechanical hard drive laying around, that’ll work fine too. The Case I highly recommend against trying to cram a bunch of GPUs into a conventional PC case. You have two realistic options here: buy a purpose-built mining frame, or build something yourself. The first option is straightforward, if not a bit more expensive. Of an open-air frame that will accommodate up to 6 GPUs.

You’ll pay a premium going this route, but it’ll save you some time and effort. Building your own is much cheaper, and (arguably) more fun! If you’re handy, you can put together a simple aluminium frame yourself for a fraction of the cost of buying one. If you don’t have the necessary skills or tools for that, I popularized building mining rigs inside plastic crates back in 2013, and that still works fine today (for up to 4 GPUs or so, anyway). At the bottom of this post, you’ll find instructions on how to build a plastic crate “case”. Risers & Miscellaneous Stuff If you’re building your own case (whether it’s from a plastic crate, or aluminium, or something else), you’ll need risers to connect your GPUs to your motherboard. If you’re buying a mining frame, most include risers.

Risers tend to be pretty misunderstood among new miners, so here is what you need to know: • Risers can be powered or unpowered. A riser is unpowered if it simply connects a GPU to a motherboard PCIe slot. A riser is powered if it additionally accepts power from the PSU (generally via a molex-type connector). Unpowered risers allow GPUs to receive up to 75 watts of power through the motherboard’s PCIe bus, just as if they were plugged in directly. Powered risers will take that additional power directly from the PSU instead, bypassing the motherboard. • You may mix unpowered and powered risers, but the total number of unpowered risers should not exceed two (this includes GPUs plugged directly into the motherboard)! Motherboards are generally not designed to deliver more than 150 watts of total power through the PCIe bus, so two GPUs on unpowered risers is the safe maximum (2 x 75 watts).

• The newer USB-style powered risers often include SATA-to-molex power adapters. Throw these adapters away! SATA plugs are not designed to deliver 75 watts safely, and these can get hot enough to potentially be a fire risk (admittedly, 99% of the time you’ll be fine, but it’s not worth the risk).

Instead, connect the molex plugs on the riser directly to your PSU (no more than two risers per PSU plug). Newer versions of these USB risers forego the molex adapter and instead use a PCIe connector for power. PCIe risers: click to enlarge. I do think the newer USB-style risers are the way to go—they’re longer and easier to work with than the old ribbon-style cables. Here is a with the newest (and safest) PCIe connectors. It’s always smart to buy an extra or two, as defects are relatively common. If you have older ribbon-type risers laying around, or can get them cheaply, they’ll work just fine.

If you’re building or buying a large frame, you might need extenders for some of your plugs and plugs. You’ll also need a power button, unless your motherboard has one built in (which is fairly rare)., or you can build one into your plastic crate if you plan to go that route (see below). Some people have reported that their rigs won’t boot unless they have a monitor connected, although this seems to be fairly rare (my own rig boots fine without a display attached). If this happens to you, you’ll need a. Building your Mining Rig “Case” from plastic milk crates (I’ve copied the instructions from my original 2013 guide here and updated them slightly.) Here is what you’ll need to create a simple DIY plastic crate housing for your miner: (can stack two and put your PSU in the lower one) $10 each $3 6 x #4 3/8″ wood or metal screws $1 Brace to rest GPUs on (1″ PVC pipe works great!) $2 a few (8″ or so) $2 (optional) $5 You can get plastic crates in most home improvement stores if you don’t want to ship it from Amazon (it’ll be cheaper, too!). I picked mine up at for under $5 each. You should be able to get everything else on the list at Lowe’s if you happen to have one near you, too. As far as tools go, you’ll need a drill and a knife capable of cutting into whatever plastic crate you buy.

Assembly Steps: First, attach your CPU & heatsink/fan to your motherboard, and place your RAM into the memory slot(s). Then follow the general steps below to mount everything into your plastic crate. Click the images for a close-up look at each step. • Place plastic standoffs on the bottom of your plastic crate, and rest your motherboard on top of them. Make sure that all of the essential ports are accessible (SATA, USB, keyboard, mouse, etc). Use your knife to cut away pieces of the crate if necessary so that all ports you plan to use are exposed.

Then plug your riser cables into the PCI-E slots of your motherboard. • Place your brace (1″ PVC pipe is really ideal and won’t flex over time) so that it is sitting above the motherboard, high enough for your GPUs to rest on. Cut the brace so that an inch or two sticks out on either end of the crate. • Drill holes in your brace so that you can secure it with cable ties (see image). Do not simply rest the brace on the crate! An accidental bump can cause it to fall into the crate, along with ~$1000 worth of GPUs if you do that! • Connect each GPU to it’s corresponding riser cable, resting the bracket end on the lip of the crate and the other end on your brace.

• Screw each GPU down into the lip of the crate. If you drill small pilot holes ahead of time (mark where to drill with a sharpie), this is much easier. • If you have a power switch and LED, mount them into one of the crate’s corners. I was pretty sloppy with mine, but it’s functional. Simply connect everything to your power supply and you should be ready to power your rig on for the first time. If you have a second crate, you can put your power supply in there (along with your harddrive if you’re using Windows), and stack it under your main crate to save some space. In the, I’ll show you everything you need to do to start mining under Linux (or skip to if that’s more your thing)!

Hi all, I have an Asus B150M-C it has 2 PCIex16 and a PCIex1 slot. I have recently bought two ribbon extenders in the hopes to add a third GPU via the PCIex1 and a powered riser.

My GPU’s are: 2x EVGA Geforce GTX 1060 6b (These are attached to the ribbons, attached to the 2 PCIex16 slots) 1x PNY Geforce GTX 1060 6b SC (THis is the GPU attached to the PCIex1 and the powered riser) My PSU is an EVGA 850GQ The issue: When all three are connected my screen goes all wonky. Nothing really works. When just the two extenders are attached everything works fine. When just the single riser is attached everything works fine. But I can’t get all three to work at once.

Thanks for the tutorial, it was great! I built my first rig but have yet to power it up so ce i am very concerned with the way my risers would be powered after all the SATA burning we see on the internet. I have a question: I am currently supplying power to 3 GPUs using one cable to the PCI-e port of the PSU for each (nothing else is plugged-in so I have one port hanging for each GPU).

1) Is it safe to use this extra hanging PCI-e plug to power the riser in addition to the GPU? (So each cable will power a 6-PIN riser and a 570 GPU). 2) if not what would be the safest alternative?

I really don’t wNt to use those SATA plugs. I have risers similar to the ones in the tutorial only in VER006. Thanks in advance! If I understand you correctly, you have 3 GPUs plugged into USB-style risers (), which are in turn connected to your motherboard. All of your GPUs have a single 6/8 pin PCIe connector, which is connected to the PSU.

How Is LBRY Credits LBC Value Determined. The PSU’s PCIe cables each have two 6/8 pin connectors, and you want to use one of these to power each riser (the other is connected to the GPU). If I have it all correct, then yes, that’s absolutely fine. Throw away the intermediate SATA-to-PCIe plugs that came with the risers, they’re generally not safe for use. I have a noob question regarding graphics card selection.

Is it better to get RX580 graphics cards with 8+6pin power or the ones with only 8pin power? I assume cards with 8+6pin would draw 150W+75W from the pcie cables so the powered riser may have less stress? But that would mean the riser needs its own power input cable which can be scarce depending on the PSU setup. On the other hand, if I get a RX580 card with a single 8pin power input, and PCIe cable with 8pin+6pin then can I plug the same cable into both the card 8pin and riser 6pin sockets? Thanks in advance!

I have ZERO computer skills, and I am sorry if this question come across as stupid but I truly don’t have a clue how this all works. Do you happen to have directions for putting this together? Also, when everything is put together do I just turn it on and start mining? I am sure that I will need software to work this but do you know where I can get the software needed to run these? I am so sorry that I am asking noob questions, but I seem to always have more questions that keep popping up. What I say below is purely my opinion after working with mining for only 1 month.

Take it as that only. 1) Motherboard. Best Free Metaverse ETP ETP Mining Software. I do not like the Asus B250 Mining Expert. Sure it supports 19 cards on one board which sounds great like it will save you $$ on additional memory, cpu, hard drive etc.

However, to get it running with 19 cards you have to have 32GB of memory and use specific Nvidia P106 mining cards which don’t even seem to be available. I haven’t used the ASRock so I can’t comment, however I really like the Biostar TB250 motherboard. The Biostar will run 10 cards using Linux without any special cards or endless tweaking and technical knowledge. I currently have 2 Rigs of 10 Nvidia 1060s each running stable, 24 hours a day using mainly the directions found on this website. I use the most current UBIT risers using the supplied 6 pin to SATA adaptor. Easy to attach and stable.

3) Mining Rig Case. No need to purchase a specific mining rig for 100’s of $$$. They are nice and well made but a waste of money. Buy a three tier Metal Storage Rack from Walmart for about $30.

Good air flow, stable and easy to move. Put your motherboard and power supply’s on the middle shelf, 5 GPUs top shelf and 5 GPUs bottom shelf. Can easily attach everything and shelf is stable yet easy to move. For the GPUs they won’t sit upright themselves, however if you get a dowel from walmart (sold in the craft area) (1/4″???) you can hook each of the GPUs to the dowel using a small binder clip and they will sit perfectly straight and support each other from falling. 4) Remote reboot and power management.

There is a device called an iCoostor. It will monitor your power usage and give you the opportunity to cut power to your rig remotely.

This can be important 1) to know your power costs 2) if your rig hangs you can cut power using the iCoostor and then when you restore power (all remotely) you can have the BIOS set to automatically reboot your rig. That combined with the automated startup scripts provided on this site will have you back up and mining in minutes from anywhere you have an internet connection using only your smartphone. 5) Spend the extra $ and get a CPU that supports hyperthreading. It will cost you $80 instead of $50 but I have 1 rig that uses a 2 core 2 thread processor and I can’t do anything else on it effectively while its mining. Not that you’ll use it for much else but sometimes you want to research on the web using the machine you are trying to tweak and not having a fast enough CPU makes that frustrating. 6) Use this site!!! 85% of all the information you need to have an effective mining operation is on this site.

Its well written, well thought out and a great starting point to get you up and running with the least amount of headaches. The linux step by step instructions are awesome and easy to use. 7) Don’t be afraid of Linux. I never used it before I started mining but this site makes it easy for mining. Very stable, easy, fast and free.

Whats not to like.

I have a Private Ethereum Network. I just want to do Ethash CPU mining using ethminer. I know that to have a smaller foot-print it is recommended to use GPU or openCL but for private networks, I only have few nodes on the network and all are CPU nodes. I just want my CPU node able to mine. • For small private networks, I believe mining with CPU nodes, where all nodes are also CPU nodes in the network, will be no problem.

With the current model, if we have a Parity node there is no way for us to mine using a CPU node. And I am not sure why Parity forces users to mine with only GPU node. Since I do not have any GPU machine on my small private network, I am unable to use Parity node to do mining, it forces me to switch to geth node to do mining.

I have followed. Install: git clone --recursive cd cpp-ethereum Build: cmake -H. -Bbuild cmake --build build After the build; ethminer used to exist under build folder on older versions git-tag:( untagged-1d50efdb2f). After I build, ethminer does not exist under build.

So I was not able to find ethminer binary. [$]~/cpp-ethereum/build$ ls _3rdParty deps libdevcore libethereum libwhisper CMakeCache.txt eth libdevcrypto libevm Makefile CMakeFiles ethkey libethash libp2p rlp cmake_install.cmake ethvm libethashseal libweb3jsonrpc test CTestTestfile.cmake include libethcore libwebthree utils So I have followed to install ethminer. This line to work for CPU mining:./ethminer -F The error I am facing with the current/latest ethminer:./ethminer ✘ 11:20:06 ethminer No OpenCL platforms found [Q] Is there any way to prevent this error and force ethminer to mine on CPU platform?

I guess we have find an older ethminer client that accepts -C/CPU flag. I have also tried: Genoil/cpp-ethereum and it says../ethminer CPU mining is no longer supported in this miner. Use -G (opencl) or -U (cuda) flag to select GPU platform. Thank you for your valuable time and help. Note: Two bounties did not return any answer. I opened an issue under github's ethereum-mining/ethminer hoping it will reach someone.

You can follow from. Please note the the github code I am sharing is forked from and Version 1.3.0 of etherminer that actually can do CPU mining, which is implemented around 1 year ago.
