The Kolink PCI-E x 1 to Quad x 16
- Quad-Mining Rendering Upgrade Adapteris the ideal accessory to build or extend a mining rig with up to four graphics cards & considering the available bandwidth can be used with separately available riser cards for other systems & applications such as Altcoin Ethereum or Ether or Zcash as well as for Distributed Computing Rendering & Boinc Bitcoin is a virtual payment method launched in 2009 that is created & managed by all participating clients of the decentralized Bitcoin network Like many other proof-of-work cryptocurrencies bitcoins are generated by computer-solving cryptographic computational tasks that consume a lot of energy called "mining" Meanwhile GPU-based mining for bitcoins is no longer worthwhile due to the immensely increased demands As a result new cryptocurrencies so-called Altcoins such as Ethereum are constantly being launched which continue to be profitably mined with GPUs In principle normal computer processors (CPUs) are capable of scrapping new Altcoins but they can only calculate a few (kilo) hashes per second & are therefore not suitable for mining in relation to the time & energy used for this purpose In terms of efficiency they are significantly beaten by graphics processors (GPUs) especially graphics chips of the Radeon series from AMD have proven to be particularly powerful As so-called mining rigs PC systems are referred to from commercially available hardware components whose sole task is Calculate crypto currencies using multiple graphics cards In order to counteract the resulting high heat generation & to operate as many graphics cards as possible in parallel these GPU-Miner systems usually use very open housings (comparable to benchtables) or partly adventurous self-built housing creations As with AMD Cross Fire or NVIDIA SLI gaming PCs the system boards do not usually use all PCI Express slots as powerful graphics cards usually have wide dual fan or even triple fan coolers & so the space required for other GPUs is missing or in the case of many mining PCs all PCIe slots must be routed based on the respective graphics card constellation This is where the handy quad-mining adapter comes in & allows four graphics cards to be connected to a PCIe slot on the motherboard when combined with separately available riser-card (or "to-rise") adapters The quad adapter has four USB (Universal Serial Bus) 30 ports & can be connected to as many riser cards The USB (Universal Serial Bus) 30 standard ensures sufficient bandwidth for the PCIe x 1 output slot to which the quad adapter is connected to the motherboard Since only calculations are performed by the GPU during mining & unlike video games no textures or shader data have to be transported to the graphics memory the bandwidth available here is completely sufficient for this application Technical details Connectors Plug PCIe with 1 lanejacks 4x USB (Universal Serial Bus) 30
