Biostar TZ590-BTC DUO Equipped with features that encourage digging enthusiasts, the TZ590-BTC DUO homeboard presents excellent performance for mining cryptocurrency Chia or Ethereum with intelligent design. Designed based on the Z590, the new TZ590-BTC DUO motherboard is a powerful beast, tailored to handle games and occasional consumption of content like a master. Storage sockets The motherboard has 10 SATA III (6 Gb/s) ports and 4 M.2 sockets with an M-hole for maximum capacity. SATAIII 6 Gb/s provides higher bandwidth to download and upload HD media. Thanks to this super fast data transmission SATAIII allows incredible data growth, which is 2x faster than SATA II. PCIe M.2 4.0 is the latest storage interface that provides the highest bandwidth and lower delays. It is twice faster than PCIe M.2 3.0. Extension sockets 8 PCIe 3.0 slots and one PCIe 4.0 x16 slot for the expansion of the graphics card allow users to simultaneously play and dig cryptocurrency at the same time. PCIe 4.0 is another evolution of the ubiquitous PCI Express I/O standard of general purpose. At 16 GT/s the bandwidth of the connection is doubled compared to PCIe 3.0, while maintaining compatibility with software and mechanical interfaces.
