A guide to lean mining

    Most older crypto enthusiasts dislike any fee based software on moral and economic grounds, but it seems in 2018 that fee based mining is now a whole industry of its own.  Well, for most algorithms there is no need to pay a fee or lose valuable hashing potential when disconnecting and reconnecting to pools.

    For those that mine Ethereum, you really should not be using claymore or any other fee based miner.  Ethminer has been updated and works very well, and has pretty much *the same hashrate* as a fee based miner.  Feel free to compare received shares on your pool.  Get it here !  This applies for Nvidia *AND* AMD GPUs.

    Mineority and Squirrel research labs are also releasing the Acorn, a GPU M.2 accelerator.  It is quite pricey and results have yet to be properly examined by the community.  Same thing goes to the new FPGA’s sold by bittware and Mineority, results have yet to be properly examined by the community.

Happy Mining !

Mining news and software updates SUMMER 2018 edition

May your temps be low and your hashrates high !

Welcome to the Summer edition of Cryptominingtalk’s GPU mining news !  GPU Mining continues to be less profitable due to the “low” bitcoin price and the ever increasing difficulties.  On a positive note, many new coins have gained traction and opportunities for profit still exist.

  •  The ASIC situation continues to get crowded.  Bitmain has a variety on offer, almost all in stock.  They sell the Z9, S9, E3, X3, L3++, A3 and D3.  Innosilicon has a Zcash miner also.  On top of that Baikal also sells the N70 (cryptonight), BK-B, BK-X, and an all new dual miner for blake256r*/lbry.  Halong Mining also sells ASICS as do others.
  • GPU prices are about to drop significantly.  With the drop in profitability, new orders have been almost non-existent.  Expect delays for the new generation, as Nvidia tries to offload a glut of GPUs.
  • Cryptodredge : Fast Lyra2v2 and lyra2z miner.  84mhs/3.8mhs 1080ti.  Coolminer is a bit slower but uses way less electricity.
  • Bminer :  Will have support soon for the new equihash fork 144,5.  Now has Bytom support with 1300hs / 1080ti.
  • Z-Enemy V11v4 : Fast x16r/s miner.
  • Luxcoin PHI2 launches *again* with a new algo.  CCminer by tpruvot.

Keep in mind that mining is still very profitable.  Mining should be done with the least running costs possible.

And FPGA mining is alive and well.  Now it is being sold to consumers in more user friendly packages.  A group buy is here.  Most people are looking at the VCU1525 with 16GB of RAM.  Almost all algos are affected, even Ravencoin, so far.

Claymore ETH Dual Miner v11.4

    New update for ETH miners:  V11.4 from Claymore.  Although some people are switching over to PhoenixMiner V2.7c, you should compare for yourself and check the results on the pool where you are mining.  The latest version includes an auto-detect feature for -dcri options in ETH only mining, which is quite useful if you haven’t optimized your GPUs yet.  RX550 cards also get a small bump in speed with ASM.

Edited for 11.4.  Now with less stale shares !

Dual mining lives again !

Claymore has updated the Dual ETH miner to v11.0.  Now you can mine keccak or blake2s as a second coin.  The fee also has been brought down to 1.5% when dual mining.  Happy Mining !

 

– added new algorithm for dual mode: blake2s (stratum pools only), use “-dcoin blake2s” option.
– added new algorithm for dual mode: keccak (stratum pools only), use “-dcoin keccak” option.
– reduced devfee for dual mode, now it is 1.5%.
– for 2GB cards devfee is removed completely, i.e. on 2GB cards you can mine all ETH forks without devfee. Check Readme for details.
– added “-tstart” option.
– “-asm 2” option value now supports Tahiti, Tonga, Ellesmere, Baffin; in some cases it can be a bit faster in ETH-only mode.
– removed “-allcoins exp” option value.
– a few minor bug fixes and improvements.

Miner software updates !


    Here are a few miner updates from the past few weeks that can improve your mining uptime and performance.  For Nvidia users, you should always check out NemosMiner and the various ccminer updates here.  For AMD users, we have new updates from Claymore.  We have an update to the ETH Dual miner, now v.10.3.  These updates mostly fix issues with the latest Adrenaline AMD drivers.  The Cryptonote update is now at v.11.2.  And Zawawa has updated his Gateless Gate Sharp to v1.1.16, which is now becoming a very interested free software.

Latest GPU Rig Build


We’d like to thank our friends, Initech Solutions inc. over @ www.gpurigbuilds.com who have shared this build with us.  You can order Pre-Assembled and configured Rigs for crypto mining at a reasonable price.  We of course suggest to make your own, but those are solid rigs.


This rig hashes around 170-175mhs on Ethereum, using 800w.  It can be configured to use less power but it has to be tested for stability over a few days.  Parts include an EVGA 1000GQ, 6x Armor 4G RX570/580 GPUs, a high quality rig frame, which is stack-able, 8G of ram (really needs only 4), 32gb usb 3.0 flash drive and a Biostar TB250-BTC motherboard paired with a G3900/30 LGA 1151 CPU.

Just wanted to share what a clean build looks like compared to home made rigs.  Also available in up to 12 GPU configurations 🙂
