“Ethereum Mining-Optimierung”

About a week ago I was hunting for a few Radeon cards for a project, specifically a second Nitro+ RX 570 for a crossfire comparison, needless to say I couldn’t find one and gave up.  A friend of mine said he was looking for a second RX 480 for his setup and that he couldn’t find one outside of crazy high prices, chalked that up to EOL on the RX 480s and told him to snag a similar RX 580.  He couldn’t find one of those either.  Thinking he just didn’t know how to search, since he’s not very computer savvy, I decided to help out.  That’s when things got interestingly and eerily similar to searching for a Radeon card in late 2013 – early 2014 back when I was deep into Litecoin and Feathercoin mining.  Then I came across Ethereum and everything became clear.  While I’m not going to pretend to be an expert on Ethereum I am no stranger to the world of crypto currencies. Having spent months on end tweaking GPU bat files for LTC and FTC while setting up ASIC miners for BTC, I decided to jump in on this one to see what the craze was all about!
Very rare it’s possible that you will get better results with the Beta Blockchain Driver , but that driver only supports 8 AMD GPU’s and please try first the Adrenaline edition (In the Blockchain driver you will not need to change GPU’s to Compute mode, they are there on default).
Note, when downloading the Claymore Miner Windows may provide a warning, but if you used Claymore’s download link can you ignore this.  He is a well-respected developer who has been building crypto miners for many years.  
I’m FPGA design engineer, and I’m thinking in learning more about Ethereum to make a FPGA implementation, but I’ve read in many sites that Ethereum is ASIC resistant but I couldn’t find any technical explanation.

-tstop   set stop GPU temperature, miner will stop mining if GPU reaches specified temperature. For example, “-tstop 95” means 95C temperature. You can also specify values for every card, for example “-tstop 95,85,90”.
RED – this part shows you the real GPU’s core clock rates and its voltages. In other            overclocking tools you will only see the last one, in this case 1340 Mhz. As you noticed there are 8 of them (P0,P1….P7) and that are the GPU’s core states. This means the GPU switches automatically to default between those states, depending on how much you use the GPU. From all those 8 states, we don’t want the GPU to switch between them, we want it to run stable at the fixed clock rates we put it on. To do that we will need to DISABLE all  the GPU’s states except the last one (P7). You can disable every state from P0 till P7 simply by double clicking on its name (just go with  the mouse over “P0” and doubleclick), you will know if you are successful if that state changes colour.
One of the many advantages of having a robot run your organization is that it is immune to any outside influence as it’s guaranteed to execute only what it was programmed to. And because the Ethereum network is decentralized, you’ll be able to provide services with 100% uptime guarantee.
Well, gpuboss.com helps a lot. Take into account the Bitcoin mining performance shown by Gpuboss for each GPU : it’s not an absolute answer to our question (since Bitcoin neither use Equihash nor Dagger-Hashimoto but SHA-256) yet it’s guiding you in the right direction. Try not to focus on hashrates found on forums : those numbers depend on too many factors (mining software and its parameters, exact GPU version, driver version, overclocking, downclocking, etc). Pay attention to the power consumption in charge. You can get it from tests available on the Internet. If not, use constructors’ indicator called TDP (Thermal Design Power), which may allow you to compare the GPUs you’ve selected.  Then, find the lowest price.

Dear Kpsingh, I’m experiencing a problem that showed up today, after an unwanted windows update (that I was stopping for about 3 weeks), my mining rig slowed down a 35% in hash rate. I have windows 10. Are you or anyone else you know having the same problem ?
As the name might suggest, ethminer is where the actual mining happens. Ethminer interfaces with the GPUs and performs the work, and it gets it work from geth. To run ethminer, we have to tell it where geth is located:
EthDcrMiner64.exe -epool stratum+tcp://daggerhashimoto.eu.nicehash.com:3353 -ewal YOUR_BTC_ADDRESS -epsw x -esm 3 -allpools 1 -estale 0 -dpool stratum+tcp://decred.eu.nicehash.com:3354 -dwal YOUR_BTC_ADDRESS
   If you mine ETC on some pool that does not accept wallet address but requires Username.Worker instead, the best way is to specify “-allcoins etc”, in this mode devfee mining will be on ETC pools and DAG won’t be recreated at all.
Für Bitcoin trifft das zu und wird sich wahrscheinlich weiter zuspitzen. Mit einer höheren Blockfrequenz relativiert sich das ein wenig (wenn auch nicht drastisch), allerdings sehe ich sehr viel Potenzial auch für dieses Problem im Sharding der Blockchain ab einem bestimmten Transaktionsvolumen.
AMD introduced their new 14 nanometer (nm) RX series card at a hard-to-resist $200 price in 2016 and crypto currency mining became much more profitable as the smaller 14nm fabrication process gives this card impressive performance and low power consumption.

All computers are not created equal when dealing with massively parallel processing : either you’ve got a supercomputer with a great number of CPUs, or you create a very customized device…like an ASIC. Third solution : use your GPU, or even better : build a computer with several GPUs !
You may have to ensure you have the correct virtual memory enabled (minimum 16GB). To do this, search for system in the start menu. Open system and on the left hand side click ‘Advanced System Settings.’ Go under the advanced tab, under performance settings, and advanced again. Then click ‘Change’ under virtual memory. Uncheck the box that states to ‘Automatically manage paging file size for all drives’ and then input a custom size of 16384 (or whatever is the maximum allowable value) into the Initial and Maximum size fields. This will prevent you from having any errors with virtual memory.
Ameer Rosic uses ‘if this than that’ logic to explain smart contracts. If we create a code online on the blockchain, and someone puts money into the contract, the next action will be executed. This may be a digital contract being sent to somebody’s email, for example. This trigger may execute something else, so on and so on.
ASICs are custom built for a single hash algorithm. Therefore, you would need to buy different ASICs for each coin that you wanted to mine. Currently, there are several companies, such as Bitmain and Canaan, that design ASICs. Due to their custom nature and niche application, a powerful ASIC isn’t cheap. For high-end hash power, a single ASIC could run you $3000.
I had the brilliant idea of combining 10 such 16gb cards, with not but a power supply, small ram chip for bios, and 16 gb of ram and a memory controller, all feeding into 1 FPGA “gateway” device that would send out the work, and the biggest problem I ran into there is a data transfer latency timing issue, where basically I would in theory be submitting all stale shares because, by the time I sent the signal, processed it, sent it back, then received it, then passed it on those 10+ nano seconds would cause me to end up with an effective hash rate of below 1.5 Mh/s. so for 10 cards at 16 gb at a likely cost of $750 per card, or $7500- I could end up with a whopping 240 mh/s @ 2500 watts, IE worse than a rig of Rx 480’s.
Genesis Mining Bewertung: Genesis Mining ist der größte Bitcoin und Scrypt Cloud Mining Anbieter. Genesis Mining bietet drei Bitcoin Cloud Mining Pläne an, die preisgünstig sind. Zcash Mining-Verträge sind ebenfalls erhältlich.
With so many changes coming to Ethereum in the future, it is expected that interest in this altcoin will only continue to increase. Whether or not that means there is a future for ASIC mining hardware focused on Ethereum is a different matter altogether. Bitmain has not officially confirmed this product will come to market, and common sense says they will never do so. Then again, Ethereum’s switch to proof-of-stake may still be years away, for all we know. An Ethereum ASIC miner is an interesting idea, but for now, it’s nothing more than an illusion.
