Bitmain HNS Miner HS3 - Asic miner for HandShake cryptocurrency

bitmain hs3 The leader in the production of ASIC miners for the Bitcoin cryptocurrency, Bitmain, unexpectedly introduced its first ASIC miner for mining the little-known HandShake (HNS) cryptocurrency. The novelty is called Bitmain HNS Miner HS3. The HandShake project is different in that it uses the original Blake2B+SHA3 algorithm for POW mining, but sometimes it is called the same as the HandShake (HNS) cryptocurrency itself.

Hashrate of AMD Radeon RX 7900 XTX video card based on ETChash, ETHash algorithm

radeon rx 7900 xtx mining Miners finally got the top version of the AMD video card for 2022 called the Radeon RX 7900 XTX, in which, in addition to the increased number of blocks and memory, the developers also increased the data bus between the GPU and memory to 380 bits, which is no longer was in AMD video cards. The extended data transfer channel increased the memory bandwidth to 960Gbit / s, which will primarily have a positive effect on the hashrate of video cards in memory dependent algorithms: ETHash, ETChash, KAWPOW, etc.

rx7900xt mining The AMD Radeon RX 7900 XT video card, which went on sale at the very end of 2022, has already appeared in the first tests in cryptocurrency mining on the ETChash mining algorithm (Ethereum Classic cryptocurrency). Because ETChash does not differ much from its ancestor EThash, so the results of testing on ETChash can be safely transferred to EThash, which continues to be used for its POW network by several dozen little-known cryptocurrencies (Ethereum POW, EtherGem and others).

Osprey E300 - FPGA miner for Kaspa cryptocurrency

osprey e300 Cryptocurrency Kaspa began to gain popularity after the transition of Ethereum to POS, i.e. first of all, Kaspa is considered as an alternative for mining on video cards. Popular POW cryptocurrencies attract not only GPU miners, but also developers of FPGA and ASIC miners, which happened with the Kaspa cryptocurrency. As usual, FPGA miners appear first, and then ASIC miners that are more difficult to develop. Kaspa is no exception, because recently there was information about the FPGA miner Osprey Electronics E300, capable of mining any cryptocurrency on the KHeavyHash algorithm with a hashrate of 14GH/s.

CPU mining: what to mine on the new AMD Ryzen 7950X in 2022-2023?

Given the high performance of AMD processors in workloads and cryptocurrency mining, we were wondering how good AMD's older CPU - Ryzen 9 7950X from the new AMD 7000 series processor line is in this business. Let's try to figure out what at the moment (12/12/2022) is the most profitable to mine on this processor and whether it is generally profitable. In addition, we will test this processor and find out its hashrates for the most popular CPU mining algorithms for cryptocurrencies.

Lolminer 1.63 improved hashrate and energy efficiency in Kaspa mining

kaspa logo In the latest version of Lolminer 1.63, the developers have improved the hash rate of the RTX 2000, RTX 3000 and RTX 4000 video cards on the KheavyHash algorithm (Kaspa cryptocurrency) by 3.5%. It may seem that such a slight increase in the hashrate is not worth much attention, but if you consider that with an increase in the hashrate, the developers also managed to reduce the power consumption of video cards, due to which the energy efficiency of mining on Nvidia video cards improved by 7-11% depending on the video card model. Reducing electricity costs without a drop in hashrate is already worth your attention when almost all mining income goes to pay for electricity. And in this case, you will also receive a bonus in the form of an increased hashrate, which definitely deserves to spend a few minutes updating the miner. You can download the latest version of lolminer 1.63 on GitHub, also lolminer 1.63 is already available in HiveOS.

Test of the Nvidia Geforce RTX 4080 video card on the KHeavyHash algorithm (KASPA)

test rtx 4080 mining kaspa The fall-winter of 2022 will be remembered for a long time for miners on video cards, when you can include your equipment in mining only for altruistic reasons. And even new video cards from AMD and Nvidia cannot show at least some profit on previously popular mining algorithms: Ethash, Etchash, kawpow, beam, octopus. The only cryptocurrency that brings at least a small profit is Kaspa with the KHeavyHash mining algorithm and, it is worth noting, the RTX 4090 graphics card shows twice as many hashes in mining than its predecessor RTX 3090.

The Geforce RTX 4090 graphics card is the flagship of Nvidia's new line of gaming graphics cards for 2022, which, just like in games, should show excellent results in cryptocurrency mining. Despite the fact that autumn 2022 is not the best time for mining on video cards, in any case, it will be interesting to find out what the top new product from Nvidia is capable of.

AMD Ryzen 9 7950X CPU hashrate based on RandomX, Ghostrider, AstroBWT and PufferFish2 algorithms

CPU ryzen 9 7950x mining hashrate AMD's Ryzen 9 7950X CPU is currently the most powerful consumer CPU available. includes 16 cores and 32 threads running up to a frequency of 5.7Ghz. And at the same time it costs 699 USD, which is 100 USD less than the previous Ryzen 9 5950X model. Which quite reasonably may be of interest to buyers to use this processor for cryptocurrency mining. In order to calculate the economic efficiency of using mining equipment, in addition to the price, you need to know two more important parameters - this is the available hashrate on various mining algorithms and power consumption. If you can find the price on the website of any computer store, then you will learn the hashrate of the AMD Ryzen 7950X processor for the RandomX, Ghostrider, Dero and Bamboo algorithms from this article.

ryzen 9 7900x mining hashrate In September 2022, AMD introduced a new generation of its x86 processors with the ZEN 4 architecture called Ryzen 7000. Like previous AMD processors, the new products should only show their best in Monero cryptocurrency mining, especially since the performance in some tests is compared with Ryzen 5000 exceeds 50%. The first representative of the Ryzen 7000 to get tested in cryptocurrency mining was the Ryzen 7900X model with 12 cores and 24 threads.

Hashrate of the Intel ARC A380 video card in mining on the Ethash algorithm

intel arc a380 mining hashrate In the latest version of Nanominer 3.7.0, support for new discrete graphics cards from intel has appeared. only the initial line of intel A380 video cards appeared on sale, so the test results in Ethereum mining are known only for it. Higher performance versions of the Intel ARC A580, A750 and A780 will be available at a later date. In the meantime, you can evaluate the architecture of Intel GPUs on the younger model and extrapolate the results for more powerful solutions.

B75 USB-BTC motherboard is the most profitable kit for mining

b75 usb-btc motherboard mining Most cryptocurrency mining uses video cards, which do not work without basic computer components: motherboard, processor, memory, disk, power supply. As for a normal computer, the main component that determines the ability to connect the various components, in our case it is a video card, is the motherboard. The basic principle of the choice of motherboard for mining is the selection of the maximum possible number of video cards to connect to one motherboard. If you take the usual motherboards for gaming computers, the number of connected graphics cards will be limited by the number of PCI-Express connectors.

Apple M1 Ultra Processor Hashrate in Monero and Ethereum Mining

apple m1 ultra mining cryptocurrency hashrate In 2022, Apple released its most powerful ARM processor, the M1 ULTRA, as part of the Apple Mac Studio computer, which, in terms of its technical characteristics, is a double version of last year's M1 MAX. If the M1 Pro and M1 MAX have been tested in cryptocurrency mining for a long time, then the M1 Ultra should show about twice as high hash rates. Whether this is true or not, we will find out a little later.

Inactivity Leak is another mechanism to protect the Beacon Chain of the Ethereum 2.0 cryptocurrency

Inactivity Leak ethereum 2 With the approach of the transition of the Ethereum cryptocurrency to POS consensus instead of POW mining, the issue of the stable operation of the future Beacon Chain POS network is becoming more and more acute. The main protection mechanisms are fines for an idle node, Slashing - exclusion from the network of the validator for violating the rules of operation and leakage of inactivity. If most of the network participants are familiar with the first two punishments for validators, then not many crypto enthusiasts have heard about the punishment called inactivity leak.

Disabling the HPET timer increases your computer's mining performance

hpet timer shutdown mining hashrate All modern computers are equipped with a high-precision timer called HPET (High Precision Event Timer), which is necessary to synchronize the operation of various equipment (sound cards, video card, processor) in multimedia tasks: video games, sound and video editors, audio and video players. The HPET timer is also known as the multimedia timer. By default, the HPET timer is enabled on all computers for compatibility, but in fact in modern computers it only increases delays in work, which affects the number of frames per second and their number for rare events in games, as well as in other resource-intensive applications, including in cryptocurrency mining.

The reason for the hashrate drop in mining on Nvidia Pascal video cards (GTX 1070, GTX 1080, GTX 1080 Ti)

gtx1070 tlb low hashrate Nvidia's Pascal generation video cards (GTX 1000) in 2016 became an excellent alternative to AMD video cards in mining, although until that moment, AMD products were practically the only option for mining in terms of their characteristics. However, by 2019, users who bought GTX 1070, GTX 1080 and GTX 1080 Ti video cards for mining Ethereum cryptocurrency began to notice a gradual decrease in the hash rate of their video cards with each increase in the DAG file of the Ethereum cryptocurrency. So, for example, the hashrate of the Nvidia Geforce GTX 1070 8Gb video card in 2017 when mining ETH was 30-32MH/s, and by 2022 this video card can hardly give its owner 25MH/s. For comparison, the AMD video card of those years, the Radeon RX 480, can still show 30Mh / s or more, as in 2016, and in terms of technical characteristics, the AMD video card is noticeably weaker than the GTX 1070. Because of what the hashrate decreases only for Nvidia video cards, we will tell later in this article.

The Nvidia LHR mining limiter is fully unlocked in the NBminer and T-REX miners. Video Card Tests

nvidia lhr 100% unlock Nvidia is known not only for producing the most powerful and popular graphics cards for mining, but also for mining hashrate limiting technology called LHR. LHR technology began to appear in graphics cards in May 2021 with the announcement of the Geforce RTX 3070 ti and RTX 3080 ti graphics cards. Throughout this year, all mining software developers fought for every percentage of Nvidia unlocking these artificial restrictions, eventually reaching a figure of 79%. All this time, miners with LHR cards felt cheated, because. for the same price, they received less hashrate in Ethereum mining. Until May 2022 hits, or until the next crypto market crash begins, or until video cards are sold at recommended prices (everyone can choose a more pleasant version for themselves). Because it is at this moment that a new version of NBMiner and T-REX is released, which completely remove the LHR block for mining the Ethereum cryptocurrency.

Video Card Thermal Pad Size Database

dimensions of thermal pads for nvidia gtx 1070 graphics card On the eve of summer, many miners face the same question of improving the cooling of equipment. Which can be solved in many ways, for example, by increasing the speed of the fans on video cards, which reduces their resource. You can turn on the additional air conditioning of the premises, which increases the cost of electricity. You can reduce the consumption of video cards, which will affect the hashrate and mining income, respectively. You can also carry out maintenance of your video cards with the replacement of thermal paste and thermal pads on memory and batteries. If there are usually no problems with replacing thermal paste on the GPU itself, then replacing gaskets with new or more efficient ones usually causes problems, because. it is not known what thickness and size of thermal pads you need to buy for a particular model of video card. Moreover, for each manufacturer of video cards, the sizes of gaskets can vary widely.

T-REX 0.25.12. Testing Nvidia RTX 3000 video cards with LHR in Ethereum mining

rtx 3080 lhr mining t-rex In the latest version of T-REX 0.25.12, the developers claim that they managed to unlock 78%-79% of the capabilities of Nvidia video cards with the LHR mining blocker. Let me remind you that we recently tested Lolminer 1.47, which has a maximum LHR unlock level of 78%. Accordingly, T-REX today should give the maximum hashrate for such video cards, which we will now check.
