Boost Performance or Optimize Power Usage on AntMiner S9 and L3 ASIC Miners

14, Nov 2022

The Bitmain AntMiner S9 series for Bitcoin (BTC) mining and AntMiner L3 series for Litecoin (LTC) or other Scrypt crypto coins re now legendary as although a bit old already they are still being used around the world and can still be nice to play around for various custom projects. You can pick these ASIC miners pretty cheap at the moment and use them as space heaters with a little tinkering to make them not so noisy. And they will not only provide you with heat or the cold winter days, but will also pay for some of the electricity they use by mining some crypto coins for you. So, although they may not be profitable if you think about them as miners, they can be turned into great space heaters that will still be better than regular heaters that only use a lot of electricity to generate heat.

If you still have and Antminer S9 or AntMiner L3 series of ASIC miners from Bitmain, or get some used units cheap, then you might want to check out the Hiveon ASIC Firmware for these devices as it will allow you to easily tweak them for either performance or efficiency. There are easy to use profiles to help you run the miner at the exact settings you want to with multiple options in between optimal power efficiency with reduced hashrate or highest possible hashrate. So, you can turn your AntMiner L3+ into a power efficient 500 MH/s Scrypt miner with 660W of power usage, or a 720 MH/s miner at 1300W of power usage or a few more options in between. Then you can head on to dual mining Litecoin (LTC) and DogeCoin (DOGE) for maximum earnings and the same applies to the AntMiner S9 series where you could be mining Bitcoin with a hashrate of 8.8 TH/s at 680W of power usage or up to 19.1 TH/s with 1880 Watts of power if you manage to properly keep the miner cool.

But HiveOn does not only offer alternative mining firmware of these ASIC miners, it comes with a complete management platform ASIC Hub for easier mining with ASIC miners, especially if you have more than just one miner. And there are not only the older S9 and L3 models supported with alternative firmware, newer Bitmain AntMiner ASICs are also available for use such as the S19 models or the T19. The ASIC Hub supports much more ASIC mining devices with their standard firmware from Bitmain, WhatsMiner, Avalon (Canaan), Innosilicon, Ebang etc. So, if you still haven’t checked out what features and advantages you might get with your mining hardware. Then there is also the HiveOS for GPU miners by HiveOn, if you still haven’t checked this one out as well.

Get Up to 30 MHS from Mining Ethereum on AMD Radeon R9 290/390 GPUs

22, Jan 2021

It is time to dust off those old AMD Radeon R9 290/290X and Radeon R9 390/390X GPUs with 8G VRAM you may have lying around and wondering what to do and make them mine Ethereum (ETH) with full power and some nice profit as well. The Hawaii and Grenada GPUs that these Radeon video cards use feature a 512-bit wide memory bus and that is more than welcome for mining Ethereum, even if they are already pretty old. You can be getting about 29-30 MHS hashrate for mining Ethereum (ETH) with these, although they are more power hungry than more recent GPUs that offer the same performance it is still worth it with high mining profit we have at the moment.

With Radeon R9 290/390 GPUs there is a bit of a catch in order to get 29-30 MHS Ethash mining hashrate with about 150-200W of power usage per video card (with optimized video BIOS for lower power usage). It is only possible to do it under Linux as the AMD video drivers for Windows 10 do not feature support for Compute Mode for Hawaii GPUs and you can get only 14-15 MHS, but the Linux drivers do and you get 29-30 MHS. What you need to do is to make sure you have up to date video drivers and that you are using the latest version of PhoenixMiner in order to be able to fully utilize the Radeon R9 290/390 GPUs for mining Ethereum (ETH).

If you are not very good with Linux you can make your life much easier with a dedicated crypto mining operating system such as HiveOS. HiveOS simplifies getting a mining rig with AMD Radeon R9 290/390 GPUs ready for mining Ethereum (ETH) with the full 29+ MHS hashrate. Again, in order to be able to get the optimal mining performance for Ethereum on these Hawaii GPUs you need to stick to Linux, Windows is not an option for the full performance and HiveOS just makes it easy. Do note that for HiveOS you can use the promo code CMB10USDPROMO that will give you $10 USD in your account balance!

How To Still Mine Ethereum With AMD Radeon RX 400/500 Series 4GB GPUs

21, Jan 2021

AMD’s Radeon RX 470/480 and RX 570/58 with 4GB of video memory can still be used to mine Ethereum (ETH), even though the DAG size is already a bit over 4GB which is more than the video memory available on these GPUs. The current Ethereum DAG epoch number is #389 and the size of the DAG file is 4.04 GB and it will continue to grow, however with the current profitability mining ETH makes it worth to continue using these 4GB video cards at least a bit more. They can still be used in the so called “Zombie Mode” with a mining software that supports it in order to continue mining Ethereum for a bit more, even though the hashrate is going to be lower and continue to go down a bit by bit with each new DAG epoch coming.

At the moment an optimized AMD Radeon RX 400/500 series GPU with 4GB video memory should be capable of doing 17-18 MHS for Ethash mining with optimized memory timings and downclocked GPU with about a 100W of power consumption at the wall. So, do not be in a hurry to dismiss these “old” and “obsolete” 4GB video cards yet, they still have some life in them for mining Ethereum, you just need to play a bit more to make them work.

The AMD crypto mining software that supports “Zombie Mode” for AMD Radeon 4GB GPUs includes TeamRedMiner, lolMiner and PhoenixMiner and they are available for both Windows and Linux OS, free with some development fee built-in. You will need to add the following command line parameters for each specific miner to enable the “Zombie Mode” and make mining Ethereum work. Have in mind that the number might need to be changed up/down in order to find what works on your mining hardware. Currently we are using 4074 on our test video cards (Gigabyte RX 580 4GB), but on different cards and with a change in the DAG number you may need to set a different number, so do try what works for you.

– For TeamRedMiner: --eth_4g_max_alloc=4074
– For lolMiner: --4g-alloc-size 4074
– For PhoenixMiner: -daglim 4074

If playing with the miners directly is not your thing you may also try the SimpleMining or HiveOS Linux Mining Operating Systems that make it much easier for management of multiple mining rigs. They do come with support for the three miners we have mentioned and thus Zombie Mode for mining Ethereum (ETH) on 4GB AMD GPUs, so you just need to prepare a USB flash drive with the OS on it, plug it in the mining rig and boot from it. Then you continue from a web-based management windows through your browser setting up and monitoring your GPUs. Both SMOS and HiveOS are free to try with a limited number of mining machines and then you need to pay a small monthly fee for additional mining rigs, to continue using the OS. For HiveOS you can use the promo code CMB10USDPROMO that will give you $10 USD in your account balance to play with.
