Computer Specifications….

When we first started building these we did a lot of research, buying different parts to get the best combo of parts, unfortunately most of those parts are no longer available and we have been using better, more costly parts instead.

EthDouble Machine Specs.

We are currently using two matched GeForce GTX 1060 video cards with 6GB of RAM in each card.  (We can make a 3GB version for less but that will stop mining Ethereum in May of 2018, but if you plan to mine for a different coin this option will save you $100) For the case, we use a nice full size ATX case, with room for at least 5 120MM Fans which we install.  For the RX 580 Systems we were using a high quality 500W PSU or larger (These systems used only 380W of power on average, for the 1060 systems we use a high quality 450W PSU (These systems use under 210W of power while mining at full speed).  We use a high quality MSI motherboard with the A88XM Chipset, the A88XM-E45 V2.  Unfortunately this board is out of stock nationwide so we have changed to a Gigabyte board that is similar, but costs more.  We use the A4-7300 as our main CPU, and the Athlon 840 for those who order the quad core version.  We then install 4GB of RAM, and a 160GB HD.  Windows 7 is installed, along with the mining software.  We then put in your Ethereum address and test the system.  We do a lot of tweeks to the OS to make it faster and better for mining, then we OC the video card to a safe and stable level.  We then test the system to ensure stability.

Currently the 1060 system is $1250 EACH….This unit will deliver 40+ MH at 210W or below.


We also can build a Triple Machine.  We use a motherboard with 3 PCI-E 16 slots, unfortunately this comes in very limited amounts and versions and for a much larger price.   We also must use a special, larger and more expensive case, and power supply.  It also is a lot more work to build in this case.  You also get 1 more card, so the MH will be 60+ in this unit.  The price of this unit is $1900.  

We are only building these in limited amounts due to the large amount of additional work that goes into these.

There are video cards that can produce more, but they are not as cost effective as the cards that we use.  Also there are motherboards that can take up to 6 cards, but we have found that this becomes unstable, is hard to mount in the case and requires too much power from the PSU.  Our rig designs are the most cost effective way to build these mining rigs at this time and scale.  We build all of these computers with power supplies that are much stronger than required.

All of our Miners make great computers also.  You can use them for office work or even gaming.  We put decent dual core or better CPUs in all of our machines.  To make any of these computers into a user computer we suggest upgrading the RAM to 8GB, which costs only $30.  Also you can get a 250GB HD for just $10 more, 500GB for just $25 more, or 1TB for just $45 more.  For more speed on your computer we highly suggest getting a SSD Drive, 240GB would add just $140 to any system.  You can use your computer for anything you like while mining, but to get a good gaming experience we suggest that you turn off mining while you game.

We are also able to make custom high end shelf based systems.  These systems can have any number of cards.  If you are interested in getting one of these systems please contact us.  We will be willing to travel to you to set it up, for cost of travel plus a nominal fee.

Our guarantee.

We will test each computer, actively mining before we ship it, during this test we will use your account data if you provide it so that you will be able to watch the test.  We are confident in the computer that you are buying, in the rare case of your computer does not perform as expected, as shown on public pool data we will log in remotely and try to tweak it so that it does perform.  All of our computers come with a 1 year warranty against hardware defects, but once mining we can only warranty the cards for 30 days, after that you will need to return them to the manufacture.  If you have a hardware problem we will fix it or replace it during this time, you will need to pay to ship it.


Shipping is not included in our pricing.  We are proudly located in Arizona in the US, computers will be shipped from our location.  You will be charged the actual rate that we pay to FedEx, usually we round to the nearest $5.  We will contact you once your computers are ready with a tracking number.  If you have your own shipping company or would like to pick up your computers in person we will be happy to call you when they are done and arrange this with you.  If you order 8 or more systems then freight shipping is often lower priced.  We will get a quote for shipping if this is the case.  For double mining rigs here are some sample shipping rates.   CA is $40, Northern CA is $45, TX is $60, FL is $75, NY is $80, most of North East US is $80, while South East US is $75.   To get exact pricing go to FedEx and use our zip code of 85345, weight 31 LBS, Value $1200, Dimensions 24x24x18 and your zip code.

Due to high demand our current turn-around time from order until shipping is about 10 days.  We work hard to reduce this.  Furthermore we foresee a shortage in the 1060 card that we use.  At this time we have enough to fill all of our current orders and a few more extra, but once we take more orders this can quickly change.  Just like when the 580 went into shortage, we will still take orders, and orders will be fulfilled in the order that people paid until all orders are filled.

If you are not in the US you will be responsible for any duties that your nation may impose.

There is no limit to the number of computers that you can order.  All ordered will be built and processed in the order that payment clears.  Be aware that our staff can currently produce about 8 units per day, so if you order a large number of systems you could be in the que for a few days.  After we build the systems we do a live test where we mine with your address to , if there are any mishaps we do the test a second time.    If we receive a flood orders we will ramp up production to meet demand but there could be a small delay during that time.

At this time we are taking BTC, or ETH as payment, or you can mail us a check but the most popular form of payment is direct deposit into our Wells Fargo.  If you are ready then please contact us.
