This PCI Express x1 to x16 powered riser card with additional SATA 15-pin power connector is the ideal accessory for bitcoin mining systems and, of course, - while keeping in mind the available here As well as any other riser card for other systems and application areas such as Altcoin, Ethereum, Ether, Zcash, Distributed Computing, Rendering and Boinc. Bitcoin is a virtual pay-as-you-go virtual payment tool launched and managed by all the participating Bitcoin network clients. Like many other cryptos with proof-of-work principle, bitcoins are caused by computer- Cryptographic computing tasks with a high energy expenditure, which is called "mining" (mining).
Meanwhile, GPU-based mining for bitcoins is no longer worthwhile because of the immensely increased requirements. Therefore, new cryogenic cures, so-called old coins, such as ethereum, ripple or DASH, are constantly being launched, which can continue to be profitable with GPUs. In principle, normal computer processors (CPUs) are capable of calculating new altcoins, but they can only calculate a few (kilo) hashes per second and therefore are not suitable for mines in relation to the time and energy spent on them. Regarding efficiency, they are clearly beaten by graphics processors (GPUs) Especially graphics chips of the Radeon series from AMD proved to be especially computationally strong. As so-called mining rigs, PC systems are referred to as commercially-available hardware components, the only task of which is to calculate cryptosciences by means of several graphics cards in continuous operation .
In order to counter the resulting high heat development and to operate as many graphics cards as possible in parallel, these GPU-Miner systems usually use very open housings (comparable to Benchtables) or, in some cases, adventurous, self-assembled case circuits. As with AMD CrossFire or NVIDIA SLI gaming PCs, not all PCI Express slots can be used on the main system, Since powerful graphics cards usually have wide dual fan or even triple fan coolers, and therefore the space required for further GPUs is missing or must be installed with many Mining PCs all PCIe slots due to the respective graphics card constellation.
This is where the practical powered Riser Card comes in and allows the installation of PCI Express slots with x1, x4, x8 or x16 connectivity on the motherboard by allowing an additional PCI Express x16 slot to be strategic In or outside the housing. This x16 slot is electrically connected to a single PCI Express lane, which corresponds to the PCIe generation of the output slot. Since only calculations are performed by the GPU during mining and, Unlike video games, no textures or shader data have to be transported into the graphics memory, the available bandwidth for this application is sufficient.
For data transmission, the riser card is a USB 3.0 cable which, with a length of approx. 600 millimeters, allows a great deal of room for the installation of the PCIe slot. In contrast to the often used IDE flat-ribbon cables with conventional riser cards, the module can be installed better and there are further advantages in the higher stability as well as the less hindrance of the airflow. The power supply to the board is provided by a 15-pin SATA connector directly from the power supply, which is able to provide up to 75 watts of electrical power, Which are normally supplied by the motherboard's PCIe slot. The remaining energy required by the graphics card comes as usual from other PCIe connectors directly connected to the GPU. With this powered riser it is thus possible to operate up to 6 graphics cards on a mainboard without overloading the power supply or the cables of the power supply.
