The card should have at least 3 gigs of RAM or it won’t be able to properly mine Ethereum. This is due to the growing DAG file (directed acyclic graph) used in the Ethereum Proof of Work hashing process.  
Second, copy these figures into the Cryptowizzard Mining Calculator, a more sophisticated calculator which allows you to set your electricity costs, which are critical to determining profitability. Unfortunately, this calculator doesn’t automatically retrieve the current price, hashrate and block time. So, we copy those over:
In addition, this is impossible to reverse engineering the content to produce the same hash value, as if modifying the content enough to fake the hash value. This is the beauty of the Cryptographic Hash Function; even if you changed a single character, the hash value will be changed so significantly such that you have no way to control the changes.
However, as interest in the project grew, this idea became more controversial. Not everyone involved with Bitcoin Gold likes the idea of an additional founders reward – something Bcash, for example, did not have.
Es ist normal, dass die Schwierigkeit der kryptographischen Rätsel, die die Miner zu lösen haben, mit der Rechenkraft ansteigt, die sie ins Netzwerk pumpen. Das ist bei jeder Kryptowährung so und es gewährleistet, dass der Zeitraum zwischen den Blöcken sowie die Rate, mit der neue Coins erzeugt werden, stabil bleiben. Ohne eine Anpassung der Schwierigkeit an die Hashrate würde jede Kryptowährung an galoppierender Inflation leiden.
Today we’re going to take a quick look at how current generation GPUs, along with a few older ones, perform when put to the task of Ethereum mining. Cryptocurrency mining is big news at the moment and it seems just about everyone wants in on the action. We are often asked what the best to mine with are, and since we didn’t have an exact answer we decided to find out.
As for the RX 500 and 400 series GPUs, memory capacity clearly isn’t the issue as the 8GB cards still suffer. I believe the issue is memory bandwidth, at least when comparing the RX 580 to the R9 390, for example. That said this doesn’t explain why Nvidia’s GTX 1050 Ti sees no performance degradation, so perhaps it is a driver issue. Compared to the R9 390 series which features a massive 512-bit wide memory bus for a bandwidth of 384 GB/s, the RX 580 uses a 256-bit wide bus for 256 GB/s. So that could certainly explain the issue, at least when comparing those two GPUs.
Zudem versuchen seriöse Anbieter ihre Hardware zu präsentieren. Hier werden große Mining-Farmen betrieben und diese können auch präsentiert werden. Natürlich gibt es auch Betrüger, die Bilder kopieren oder fälschen, aber ein Blick hinter die Kulissen ist immer lohnenswert. Bei manchen Mining Farmen waren bereits offizielle Kamerateams, die die Existenz der Hardware beweisen:
At the moment, the rewards are at 12.5 Bitcoins per one block. The reward began with 50 Bitcoins per block, and it has been lowered in every four years. It came down to  25 BTC/Block in 2012, 12.5 BTC/Block in 2016, and is expected to fall at 6.25 BTC/Block in 2020. This is what miners are supposed to get ready for.
IMPORTANT: You MUST have the latest motherboard bios installed. (you can check your motherboard bios update history, to see what was changed from your bios version till the latest available one. If there are no major changes, then you can skip this step.(Chipset, PCI-E, GPU support changes are the most important ones and you NEED to upgrade your Motherboard BIOS if they came out).
I am new to mining and want to build a rig. I think I have enough money invest in a very nice setup. Can you please tell me if the Gigabyte GeForce GTX 1070 Windforce OC is the best GPU available on the market right now?
If some cards are 2GB and some >2GB, 2GB cards still mine for you during devfee time, only cards that have more than 2GB memory will be used for devfee mining. Miner displays appropriate messages during startup.
While the ROI – Return on Investment can go past a year for the Ethereum mining GPUs that have been mentioned above, it can be reduced if you opt to use more than one GPU. You will not get much by using just one video card to mine, and so deciding to purchase more than one GPU will be the best thing to do. But before you fully venture into that, you should also make yourself aware of the profit your mining rig will bring as well as the amount of money that you will spend on the energy.
If you are wondering if it is worth mining Ethereum you can get an idea on how much Ether (ETH) should be mined with a specific hashrate depending on what hardware you have available with a simple mining profitability calculator. All you have to enter is the hashrate you are getting (you can run ethminer in benchmark mode to see what hashrate to expect from your CPU or GPU if you have not yet started mining) and you will get information about the expected mined amount in ETH and USD. The calculator uses up to date data from etherchain’s API to get fresh information about the Network Hashrate, average Blocktime and 1 ETH price, so it should be pretty accurate with the results at the moment of time you use it. The estimated coins to be mined and their USD value are shown for a period of 1 Minute, 1 Hour, 1 Day, 1 Week and 1 Month, though the longer the period is the less accurate the estimation could be.
(Update: Bitcoin Core is less usable as money due to much higher fees and delayed transaction times. The Core team has also expressed an interest in keeping these fees high since they view BTC as a “store-of-value” and not something to be transacted on a daily basis. In contrast, Bitcoin Cash’s transaction fees cost pennies and payments can be validated even with zero confirmations. These facts make BCH the ideal cryptocurrency for sending and receiving money anywhere in the world.)
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).
It is very easy to burn out your GPUs – I’ve done in two, but luckily got warranty replacements. The first just stopped working after one day. And one of the fans got “sticky” in the second one after a few months.
