How to set up and run Claymore’s Ethereum miner on Windows

If you’re new to mining, you’ve probably encountered — at one point or another — a mention of Claymore’s Ethereum miner. It’s one of the most popular, if not the most popular, software for quickly and easily getting your mining rig up and running. It offers extensive control features, runs smoothly, and even allows on-the-fly tweaking of certain parameters without a restart.

But for those who are just now getting into this mining thing, it might be a bit confusing to get running. What’s a config file? What are parameters? How do I get this thing to make me money?

How to build a mining rig for Ethereum

Mining cryptocurrency is becoming an attractive source of secondary (and passive) revenue for many, and one of the most popular cryptocurrencies to mine right now is Ethereum. That’s because, in the realm of cryptocurrencies, it’s easily the second most established — only behind Bitcoin. That caused its price to skyrocket over the course of 2017; it went from less than $20 at the beginning of the year to near $1,000 by the end. Anyone that was into mining Ethereum in the early days made significant gains.

And while the price is now significantly higher than it was at this time last year, that doesn’t mean it’s a bad idea to start mining it. In fact, even with as popular as mining the coin is, it’s still fairly profitable as long as you don’t have to pay that much for electricity. Before you get started, you need to build what’s called a mining rig. It’s basically a PC with lots of graphics cards. In this guide, we’re going to walk you through which hardware you’re going to want to buy, as well as how to put it all together.

Best Hardware for Ethereum Mining Rig

Power Supply Unit (PSU) –  What’s the best PSU for mining Ethereum? First, let’s start with the power supply. You might not expect it, but getting the right power supply for your mining rig can be critical to your sustainability as a miner. Indeed, it is the power supply that will determine a lot of how power-efficient your mining rig is, and therefore how much of the cryptocurrency you mine is actually profit. There are a few things to look out for with buying a power supply for your mining rig, but two of the big ones are safety/quality and power efficiency. Just about any standard power supply will work with your mining rig (so long as it has enough wattage), but there are some that are more ideal than others.

Good 1200 Watt options for your 6 GPU rig (Corsair and EVGA are great):

With 6 GPUs all running at full-throttle, it’s best to stick with a 1200W (or higher, but not too high) power supply. If you’re going to go with 4 GPUs (which many people do, despite the hit to profits), then a 1000W power supply will probably be fine. Again, however, it’s best to stick with the power supplies in the highest “platinum” category to maximize your profits, if you can afford it.

Or, if you’re going to be sticking with 3 or less GPUs, an 850W supply will probably do the trick:

Motherboard — What is the best motherboard for mining Ethereum? There are lots of doable motherboard + CPU combinations that will work for building an Ethereum mining rig, but actually finding one in stock can be a bit of a headache. Some sites sell pre-configured motherboard + CPU products, but if you want to save some money, it might be worth your effort to look around on Amazon and eBay to find a good combination that will work for you.

It goes without saying that you’re going to want a motherboard with the same number (or more) PCI slots you’re going to need for your graphics cards. If you are willing to settle for using less than 6 GPUs in your rig (and thereby getting less profit), there are tons of options to choose from. But if you want to stay true to the plan, max out your profits, and run 6 GPUs, you’re going to have to do a bit more digging. Finding the appropriate combo on some hard-to-find motherboards can be a bit of a task.

The below are easy links to Amazon, but if you can’t find one on Amazon, it’s also worth checking eBay and Newegg for stock.

The two most popular boards (and therefore the best for getting support online:

Other options that will work just fine:

For more motherboard options, check out our extensive list.

CPU — Now, what is the best CPU for mining Ethereum? That’s a much easier question: get a cheap CPU that works with the slot on your motherboard. If you’re going to get one of the above motherboards, chances are you’re going to need an Intel CPU for slot LGA 1150. Unless you plan to use your rig for something other than mining, you should just get a budget Intel Celeron CPU to keep the cost of your rig down.

RAM — What’s the best RAM to buy for mining Ethereum? To go with your motherboard and your CPU, you’re going to need some RAM for your rig. The most economical purchase is likely to be a single stick of 4GB DDR3 RAM. If you want to run other applications on your rig for one reason or another, then perhaps go with 8GB. Regardless, you don’t need much RAM to mine. Keep in mind that, depending on the motherboard that you buy, you might need to get DDR4 RAM instead.

Graphics Cards (GPUs) (4-6x) — What’s the best GPU for mining Ethereum? There are lots of good answers to this question, but as of the time of this writing, the answer is: whatever cards you can get your hands on. Stock is so limited that almost anything is better than nothing, but there are still a select few AMD RX cards that you should probably stick to.

The actual brand of the card is not the most important part (although some are better than others, like the usually-higher-quality Sapphire and MSI), rather you want to make sure you get the right AMD chip. A variety of manufacturers make cards using AMD RX 470, 480, 570, and 580, and just about any of them will work fine. Also, it’s likely a good idea to get an 8GB RAM card. A mix of these cards will work just fine — it might just take a bit of time to get the drivers working properly.

  • ​​​AMD Radeon RX 580 – An RX 580 will likely get you around 29 Mh/s, and when stock is available, it’s a great card for mining Ethereum.
  • AMD Radeon Rx 480 –    Another great card for mining Ethereum is the Radeon RX 480. This card usually gets around 27 Mh/s after a bios mod and tweaking the clock speed and uses roughly 150 watts.
  • AMD Radeon Rx 470  –   Basically the smaller brother of the RX 480, the RX 470 is widely regarded as the best bang for your buck in Ethereum mining — as long as you can find it. After you mod it, you’ll get around 29 Mh/s, and it consumes around 140 watts.
  • Gigabyte GeForce GTX 1070  –  While I would recommend against getting an Nvidia card (they tend to have less support from mining software), it’s impossible not to mention the GTX 1070. It will get you around 28 Mh/s and uses almost half as much energy as the RX cards, so while it may be expensive up front, it might pay off for some in the long run.

PCIe Risers — What are the best PCIe risers to use for mining? In my experience (and I’ve asked around about this quite a bit to professional miners), you’re best off using the Ver. 06C or Ver. 007 6-pin to SATA PCIe risers that you can find on Amazon and other retailers. Don’t cheap out on these — get some good quality risers. This is one area of your rig that will most likely fail at some point, and if that happens, you don’t want to lose a card or have a wire catch on fire.

1x Solid StateDrive (SSD) — What’s the best hard drive/SSD for mining Ethereum? You probably want to get a solid state drive of course (it will save you on energy and would be one less failure point for a rig that’s going to be running 24/7). A 120GB SSD will do just fine from just about any brand.

Mining Case — You’re going to need something to keep your rig put together on (you only need one!). If you don’t have the skill or materials to build your own (people have built some crazy cases out of a variety of materials), you probably want to get something that was assembled by someone else. Something like this one on Amazon would work perfectly.

Operating System —  You have a few options when it comes to operating system. I personally went with Windows 10 for my rig (most software for mining will work fine with Windows, and I already had a key laying around from an old computer). But if you don’t already have access to Windows 10 for free or cheap, Eth OS is a linux OS that mines coins like Ethereum and others pretty well.

Accessories —  Of course you’re going to need a cheap Mouse and Keyboard to get everything set up, but chances are if you’re looking build a rig then you already have some of these laying around somewhere. Also, don’t forget to buy a cheap power button for your rig so that you can easily turn it off and on. Also, don’t forget to find yourself a Monitor. Also, a couple fans would be useful to keep things cool. Zip ties will come in handy for mounting your GPUs and fans to your case.

How to Assemble Ethereum Mining Rig

After you’ve managed to pick up all of these parts, you have to embark on the actual process of building your rig. So how do you assemble an Ethereum mining rig once you have all the parts? It might seem daunting if you’ve never assembled a computer before, but it’s actually pretty simple. Just follow these steps.

Steps to assemble Ethereum Mining Rig

Step 1 — Get your rig case set up. I ordered a wooden “case” from eBay for my rig, so it required a bit of work to put together. This step will depend on where you get your case (or if you decide to build it yourself), so simply follow the instructions from the manufacturer. My wooden “case” just required me to have a philip’s head screwdriver, and to screw in a couple screws. Then I was ready to mount the motherboard.

Step 2 — Mount the motherboard. After your mining case is set up and ready to go, you’ll need to mount your motherboard to the rig so that the bottom of it is protected from damage. My wooden rig included some spacers and screws for this, so it was pretty straightforward. I laid my motherboard on the wooden case to make marks for the holes with a pen, and then placed each spacer above the marks.

Here’s an example of these holes on the Biostar TB85 motherboard. The red arrows show the holes I would consider mandatory on this board (they were the only ones that fit on my case), and the blue arrows I left unscrewed.

I used the screw and screw driver to get a hole going for each spacer. Then I removed the screws from the wooden case, placed the motherboard on top of the spacers (this part might take a bit of work to line up all the spacers correctly), and then screwed each screw in. You’re going to want to use all of the screws that your motherboard requires, which will probably be somewhere between 7 and 10.

Step 3 — Connect the CPU. This step varies by motherboard and CPU (it’s slightly different for AMD CPUs, compared to Intel CPUs, for example), but it’s still pretty straightforward. You should always check your CPU and Motherboard instructions before proceeding, but the gist is this: open up the CPU holder using the lever, remove the plastic insert (if your motherboard has one), and place the CPU inside. You’re going to want to look for an arrow on one corner of the CPU and line it up with an arrow on the motherboard.

Click here for an easy and quick rundown on how to install a CPU on a motherboard.

Once you have the CPU actually seated and installed properly on the motherboard, you need to connect the CPU fan to the motherboard. You should see a three-pin connector that is likely labeled something like “CPU fan”. Then, you should use an 2×4-pin cable to connect your CPU to the power supply. Most likely the cable (and the GPU) will be labeled CPU. The port that you want to connect to your power cable is going to liekyl be a 4-pin port located somewhere on the motherboard near the CPU.

Step 4 — Install the RAM. You’ll see two or four slots on your motherboard for DDR3 RAM. You already ordered your DDR3 RAM sticks from Amazon (or some other dealer). Simply remove them from the packaging, make sure the levers for holding down the RAM are open, and seat the RAM in the motherboard. If you do it correctly, the stick(s) should click into place nicely on both sides and should be secure.

Step 5 — Connect the SSD. This is a pretty simple step as well. You should have an SSD which will serve as your hard drive. Connect this SSD to the motherboard using the SATA data cable that most likely shipped in the same box as your motherboard. After this, connect your SSD using the sata power cable that came with your GPU. One cable should be labeled SATA, you should connect that end to the GPU end that also says SATA, and then connect the SATA cable to your SSD.

Step 6 — Mount and connect GPUs. This is likely going to be the trickiest part of the actual hardware assembly, but it’s not that bad. First you need to take out all of the risers from their packaging, and assemble them appropriately. The PCIe 16x part will connect directly to the bottom of the video card, which connects to a USB cable, which connects to a PCIe 1x piece that connects to your motherboard. You can connect this 1x slot to the 1x slots on the board, and also the 16x slot. However, for the 16x slot, be careful to place the 1x piece in the correct direction. The below image depicts the correct placement.

After you have the GPUs connected to the motherboard, you need to mount them to the case. This can be done in a variety of ways, but the most common is to simply place the GPUs on the case and connect them more “permanently” using zip ties. Finally, after you have your GPUs mounted, you should run a cable labeled “VGA” rom the power supply unit to the 6- or 8-pin VGA connector on each GPUs, and you should connect a few SATA power cables to each of the powered risers. I recommended the 6-pin to SATA risers above, and I would further recommend that you only connect at most 2 cards per SATA cable from the GPU.

Step 7 — Mount a couple fans. To keep your rig cool, it’s a good idea to mount a couple of fans that blow towards the GPU and help air flow between your cards. There should be a couple of fan connectors on your motherboard, and it’s pretty simple to mount a fan or two with zip ties.

Step 8 — Connect your power button. You’re probably going to have to take a peek at your motherboard manual to do this correctly (it varies a little bit between boards), but you need to connect your power button to the motherboard. Just find which pins correlate with the button (they’re probably at the bottom of the motherboard, on the opposite side from the CPU).

Step 9 — Check all your connections and cable management. Mining rigs are known for being not that stable and prone to weirdness and fire etc, so it’s a really good idea to check all of your connections and make sure that everything is secure. You should have power cables running from the PSU to the SSD, the GPUs, the GPU powered risers, the CPU port on the motherboard, and the motherboard via its big power cable. And once you know for sure all of these are lined up and connected correctly, you can mount your PSU somewhere on the rig.

One little extra tip that might come in handy is that it’s worth it to use zip ties to clean up your cable management a bit. You don’t want any hot fans (like from the PSU, especially) blowing hot air on another connection. Specifically, watch out for those powered riser converter cables. You don’t want one of those sitting on top of the hot-air-blowing PSU fan. You also want to make sure there isn’t any tension of pressure pulling on any of the connections.

Step 10 — Get software up and running. I’m going to save this for another guide entirely, but after you get all this hardware set up and connected, you’re going to need to get your software up and running. If that’s EthOS, then you simply throw that OS on a USB stick, plug that into your rig, power things up, and press whatever key on your keyboard will let you choose your boot drive. It’s F8 on many motherboards. Then select the USB drive that has EthOS waiting to be installed, and follow the instructions. It’s a similar process for Windows 10, but like I said, I’ll leave this for another guide.

Coinbase now allowing users to withdraw Bitcoin SV following Bitcoin Cash hard fork

Coinbase, the popular San Francisco-based cryptocurrency exchange, has announced that users can now withdraw their Bitcoin SV, or BSV for short. The new token was the result of a hard fork in Bitcoin Cash that occurred in mid-November, which essentially split the Bitcoin spin-off into two more chains: Bitcoin Cash, and Bitcoin SV.

Ripple passes Ethereum to become the second most valuable cryptocurrency

Ripple has passed Ethereum to become the second most valuable Cryptocurrency, according to its current average price from cryptocurrency data aggregator Coin Market Cap. At the time of this writing, Ripple has a market cap of more than $100 billion, passing up the $69 billion of previous number two, Ethereum.

According to FT, today’s surge comes after three major Japanese credit card companies signed on to use Ripple’s blockchain technology.

Last week’s announcement that three of Japan’s big credit card companies have signed up to use Ripple’s technology triggered another bounce in the price of XRP, which is up sixfold in the past month and almost 300-fold in a year.

Ripple’s price has been booming for several weeks, however, going back as far as an announcement on the official Ripple website on December 14th that the Japan Bank Consortium would be partaking in a Ripple pilot with a pair of South Korean banks.

The Japan Bank Consortium — a coalition of 61 banks in Japan, organized by SBI Ripple Asia — has announced the launch of a new Ripple pilot with Woori Bank and Shinhan Bank, two of South Korea’s largest banks with a collective market capitalization of more than $30 billion.

Ripple is a controversial cryptocurrency, since it has primarily been targeted at preexisting banks, credit card companies, and payment providers to serve as an efficient way to move funds. The spirit of other cryptocurrencies, such as Bitcoin, have long been established in anti-establishment ideals.
