Which USB riser to choose for mining cryptocurrency), where the last version at the time was the ninth. Today we will tell you about the USB Riser model number 10.

Profitable ERGO mining on old Nvidia and AMD video cards

mining and hashrate of the ergo cryptocurrency on old video cards The ERGO cryptocurrency is currently one of the most profitable for mining on video cards, competing in profitability with the well-known Ethereum. ERGO, in contrast to ETH, has significantly lower equipment requirements, since even 2Gb of video memory is enough for ERGO mining. For Ethereum mining, we recall that your video card must have at least 5Gb of built-in fast memory. If you are the owner of old video cards with 4Gb video memory or less, then you should pay attention to ERGO cryptocurrency. In the direction of ERGO, it is worth looking especially to those miners who still have AMD Radeon HD 7970, R9 280X, R9 380X, Fury, R9 290X video cards, which cannot mine Ethereum due to a small video buffer, but at the same time have sufficiently powerful GPUs, which will allow get them a fairly large income when mining ERG.

Canaan has released an updated ASIC miners Avalon A11S (A1166PRO-S and A1126PRO-S)

canaan avalon sha asic miner a11s Canaan launched the updated 11 line of Avalon ASIC miners under the name A11S, even though at the beginning of 2021 a new 12th generation of SHA-256 ASIC miners - Avalon A12 was presented. Which, in comparison with the A11, has made a small step in energy efficiency. Asics Avalon A11, by the way, were also launched relatively recently - just a year ago, in June 2020. If the 12th generation of Avalons really offered improved energy efficiency (38J/TH) compared to the 11th generation (from 42J/TH to 57J/TH, depending on the model), then the 2021 model range of the Canaan Avalon A11S asic miners, on the contrary, show slightly lower quality indicators of energy efficiency (46J/TH to 56J/TH depending on model) even compared to last year's A11. Therefore, the prefix S in the name A11S can be deciphered here as you like, but definitely not as Super.

GoldShell LT5-PRO - updated ASIC miner for the Scrypt algorithm

asic scrypt goldshell lt5-pro The Goldshell company in August 2021 presented its updated model for joint mining of Litecoin and DogeCoin cryptocurrencies called Goldshell LT5-PRO. Compared to the previous model LT5, the hashrate of the PRO version increased by 20% (2450MH/s), but the power consumption also increased significantly from 2080W to 3100W, i.e. by 50%. Without tricky reflections, we can conclude that the Goldshell LT5-PRO is an overclocked version of the regular LT5 with a more powerful power supply and possibly selected Asic chips that can keep a higher operating frequency due to an increase in power consumption and a deterioration in the energy efficiency of mining in general. More information about the asik miner Goldshell LT5-PRO can be found on the official website goldshell.com.

Methods for detecting Nvidia Geforce RTX 30 video cards with LHR mining limiter

nvidia lhr mining hashrate In May 2021, Nvidia decided to limit all its gaming video cards of the Ampere or RTX 3000 series (except for the oldest RTX 3090 model) in cryptocurrency mining performance. Therefore, the new models announced in May: Geforce RTX 3070 Ti and RTX 3080 Ti come with a mining limiter by default, and models RTX 3060 Ti, RTX 3070, 3080, which initially had no mining limits, starting from week 22 of 2021 are also released from a new revision of the GPU, which will also have built-in protection against mining. To distinguish between old (unlocked) and new (locked) revisions of video cards, Nvidia introduced a new term LHR (Lite Hash Rate). The RTX 3060 video card stands apart here, which was originally released with a mining limiter, but later this limitation was bypassed and NVidia had to release a new GPU revision for the RTX 3060 with stronger protection against mining, but at the same time, the RTX 3060 video card, like The RTX 3070 Ti and RTX 3080 Ti do not have the LHR designation in their names, although in fact they are. It becomes even more confusing because almost all brands that produce Nvidia video cards do not indicate on the box or in the name of the LHR model whether it is a video card or not. Actually, in this article, we will try to tell you by what signs it will be possible to distinguish LHR video cards from Nvidia, produced by various brands: ASUS, Palit, MSI, KFA2, Gigabyte, Inno3d.

AMD Radeon RX 6600 XT - hashrate on popular mining algorithms

radeon rx 6600 xt hashrate ethereum mining AMD has not yet had time to present its junior graphics card of the RDNA 2 generation - Radeon RX 6600 and Radeon RX 6600 XT, when all the technical characteristics of these video cards and prices have already become available on the network. As expected, the RX 6600 XT will have a 128-bit memory bus together with GDDR6 memory, which in terms of memory subsystem performance will be similar to the Radeon RX 580 video card currently popular in mining, which was actually released back in 2016 in the face of the RX 480. Actually, the upcoming novelty is us and compare the technical characteristics with the Radeon RX580 and try to predict the hashrate of the Radeon RX 6600XT video card based on the Ethash algorithm (Ethereum cryptocurrency) and other currently popular mining algorithms.

Adapter PCI-E - MXM3.0 for installing mobile video cards in the PCI-Express x1 slot

mxm 3.0 pcie 1x adapter for mobile video cards You won't surprise anyone with cryptocurrency mining on laptops. Due to the ubiquitous imitation of conventional desktop graphics cards, powerful laptops with a discrete graphics card can pay off faster than a classic GPU mining rig. Discrete video cards in laptops can be soldered to one printed circuit board with a central processor, but there are laptop models in which the video card is installed as a separate device. Mobile video cards in such laptops use not the usual PCI-Express x16 slot, but a special MXM 3.0 interface, which is backward compatible with PCI-E using a simple voltage converter.

Bitmain Antminer L7 is a new ASIC miner for LiteCoin and DogeCoin

Bitmain antminer L7 litecoin dogcoin asic miner The largest manufacturer of mining equipment, Bitmain, on June 19, 2021, announced a new generation of ASIC miner for mining Litecoin, Dogecoin and other cryptocurrencies using the Scrypt algorithm. The new ASIC miner was named Antminer L7 and will have a hash rate of 9500Mh/s or 9.5Gh/s, which is 19 times more than the previous Antminer L3 + model.

Goldshell Mini-Doge - DogeCoin Asic miner

asic doge coin The DogeCoin cryptocurrency was created as a fork of the Litecoin cryptocurrency and therefore has the same mining algorithm called Scrypt, and DogeCoin and Litecoin can be mined at the same time. At the moment, all POW cryptocurrencies with the Scrypt mining algorithm are mined using specialized devices - Asik miners. And if earlier all ASICs for the Script were guided in their name first of all by Litecoin, had the abbreviation LTC or Litecoin in their name, then due to the growing popularity of the Doge Coin cryptocurrency, GoldShell decided to change this approach and named its new Scrypt miner Mini-Doge, emphasizing the point that this device can be used to mine the popular Doge cryptocurrency Coin.

Hashrate of Nvidia Geforce RTX 3080ti and RTX 3070ti video cards in Ethereum mining

hashrate nvidia geforce rtx 3080 ti ethereum low hasrate rate LHR Nvidia did not have time to announce its new Geforce RTX 3080Ti and RTX 3070Ti gaming video cards, and tests of the older video card in mining the Ethereum cryptocurrency have already become available on the Internet. As expected, the RTX 3080Ti video card showed a hash rate on the Ethash algorithm two times lower than its technical characteristics allow - 58Mh/s with a power consumption of 300W. For comparison, the RTX 3090 video card, which is close in technical characteristics, shows a hash rate of 100-120MH/s.

Innosilicon A11 ETHMaster - a new generation of Ethereum ASIC miners

innosilicon a11 ethmaster asic ethereum Innosiliconhas been producing various modifications of ASICs for mining Ethereum cryptocurrency since 2018 under the name A10, A10 PRO and A10 PRO +. Innosilicon recently introduced a new generation of Ethash mining device called the A11. A11 ETHMaster has a hash rate of 2000MH/s with a power consumption of 2500W. Although a significant increase in hash rate has been announced compared to previous models, power consumption has also increased significantly. Because of this, the energy efficiency of the A11 has not grown so much compared to the A10 - from 1.5W/MH to 1.25W/MH, or by 17%. The amount of RAM in the A11 is set at 8Gb, which is not even useless at the moment, since this volume will be enough for Ethereum mining until 2027. The first deliveries of the Innosilicon A11 ETHMaster are scheduled for July 2021.

AMD Radeon RX 6700XT - reducing power consumption on the Ethash algorithm

radeon rx 6700 xt mining ethereum AMD's Radeon RX 6700XT video cards when mining Ethereum cryptocurrency show mediocre results - 45-50 MH/s, which is much worse than the 60-65Mh/s that the previous generation RX 5700XT video cards show. This is primarily due to a decrease in the memory bus width from 256 bits to 192 bits, but the power of the GPU itself has significantly increased. From this we can conclude that the GPU power of the Radeon RX 6700XT video card when mining Ethereum is excessive and it can be undervolted to the maximum.

All Nvidia Geforce RTX 3000 series video cards released since May 2021 will have hardware protection against mining

nvidia geforce rtx 3080 ti LHR block mining

The first video card from Nvidia, which received protection from mining, was the RTX 3060. As it turned out later, the protection built into these video cards was software and is managed by special drivers or miners that remove this protection. Realizing its mistakes, Nvidia, this time with the release of new models of Geforce RTX 3070Ti and Geforce RTX 3080Ti video cards, promises even more advanced and now hardware-based protection against mining. Which will "definitely" make consumer video cards not interesting for miners and video cards will become available for the purposes for which they were originally conceived - for games.

The first test in the mining of the AMD Radeon RX 6700 XT video card on the Ethash and KawPow algorithms

amd radeon rx 6700 xt mining hashrate ethereum ravencoin Even before the start of sales of the Radeon RX 67000 XT video card (March 18, 2021), the first tests of this video card in cryptocurrency mining have already appeared on the Internet. As expected, the video card was checked for the issued hash rate using the Ethash algorithm (Ethereum cryptocurrency) and the KawPow algorithm (RavenCoin cryptocurrency). Both of these algorithms are sensitive to the memory subsystem of video cards. The Radeon RX 6700 XT has a 192-bit memory bus instead of the 256-bit one in the previous model Radeon RX 5700 XT, therefore the new product showed not the most impressive results in the mining of these cryptocurrencies.
