If you need setup support beyond the available instructions provided, we offer one-on-one setup/consulting services that can be purchased separately from our consulting page. We would be happy to guide you through the process. Is a power cord included with the miner A power cord is not included with S19k pro. We do however have splitter power cords available for sale.  How much overclocking is possible with Antminer S19K Pro? The S19Kpro is a great unit to overclock. Most aftermarket firmware companies have software available. Some bench marking exceeds 150 Th/s.You can read more about the ePIC board performance here I'm not getting the advertised 23.5J/T efficiency on stock settings. Is there something wrong with my miner? Mining efficiency is highly dependent on ambient air temperature. If your miner is pulling more power than expected, in most cases it is due to a higher ambient temperature. You can improve mining efficiency by preventing mixing of hot exhaust air with intake air.  Which control board does this miner come with? We’ve seen most units with CV1835 which is not compatible with firmware such as LuxOS. It will need an Amlogic board. AMLOGIC A113D control board if you want to use aftermarket firmware. Make sure to order the correct board that is compatible with the existing fans. Both control boards can have either 4 square ports or 2 rectangle fan ports and 2 square fan ports. Confirm visually before ordering. Does the fans on this miner have rectangular or square connectors? That depends. TheCV1835 has 2 rectangle and 2 square fan ports. While the Amlogic A113 can have either 4 square ports, 4 rectangle fan ports, or 2 rectangle fan ports and 2 square fan ports. Confirm visually before ordering fans. How can I make this quiet for home use? Stock fans on Antminers can be very loud (~75 dB) at full speed. There are however multiple ways to make them quieter. First way to make them quieter is to run them at substantial underclocking. This will significantly reduce the hashrate, but will also reduce fan noise, since the fans don’t have to run at full speed when underclocked. Another way to reduce noise is by replacing stock fans with an inline AC infinity fan. You can learn more about this here. This method allows running the miners on stock hashrates and may even allow some overclocking in many cases. Third way to reduce fan noise is by running the miners in immersion mode. In this method the miners are immersed in vats of mineral oil or dielectric fluid. This significantly improves heat transfer and enables substantial overclocking. Immersion mining however voids all warranty, is more complex to setup and immersion fluid can act as a solvent and damage some mining gear. We believe that this is still an experimental technology reserved for the most technically inclined. We do not recommend immersing Antminers to most customers for this reason. Stock Antminer firmware does not allow much flexibility in terms of overclocking/underclocking , fan control, automated temperature control etc. In most cases you would need aftermarket firmware to enable quieter operation.  Can you ship this directly to my hosting company? Yes, you can either take delivery yourself or ship this to your hosting company by providing their address under the shipping address field on checkout page.  Does this product have a factory warranty?
