Which model to choose for mining
The graphics card may differ depending on the manufacturer of the device. Each algorithm has its own requirements, for example, Ether is efficiently extracted if Samsung memory is installed on the card. Memory chips from this vendor heat up less and hold overclocking well. Graphics cards with Hynix memory produce a decent hash rate, but are hotter.
The amount of RAM is needed for the ever-increasing size of the DAG file, so a 2 GB card will be irrelevant for mining on the Ethash algorithm. Big Ethereum is no longer mined even four gigabytes. If the RX 570 can still develop up to 20 Mh / s on the cut Dag file, then the hash rate of 560 is almost zero. But the RX 560 4GB, unlike the two-gigabyte one, works great on other coins of this algorithm.
The video card Saphire Radeon RX 560 Pulse OC in the description contains the words Mining Edition, which means that it is sharpened for mining and developed by the manufacturer taking into account all the necessary parameters. If you install a modified BIOS or set the acceleration parameters in the PhoenixMiner executive file, this card shows the best performance in mining.
Video cards from ASUS are designed for the gaming community and the manufacturer pays great attention not to power consumption and overclocking capabilities, but to other parameters and backlighting with a fan. You can choose a card from Gigabyte without overpaying for unnecessary solutions. But, only the Saphire Radeon RX 560 Pulse model has additional power, which allows it to steadily keep overclocking. The cards of this line are very durable and can work without breakdowns for several years.
Chinese manufacturers have also released an RX 560 specially adapted for mining, but it is virtually impossible to find such a card in Russia, and the guarantee is dubious. The secondary market is also overflowing with offers of already assembled farms, but you need to choose such cards with a specialist and look at the hours worked. The best option if it is about 6 months from the date of purchase.
