BIOSTAR today introduced the TZ590-BTC DUO, a feature-packed motherboard for crypto-currency mining setups, based on the Intel Z590 chipset, and supporting 10th- and 11th Gen Core processors in the LGA1200 package. The board puts out a total of eight PCI-Express 3.0 x1 slots, all from the Z590 PCH, besides a PCI-Express 4.0 x16 slot wired to the CPU, and four M.2-2280 slots. One of these is PCI-Express 4.0 x4 and wired to the CPU, while the others are Gen 3, and from the PCH. With M.2 to PCIe adapters already in the wild, you can install up to 12 graphics cards on this board. Connectivity options on this board include some legacy ports, including D-Sub for video from the iGPU, besides HDMI; and a PS/2 keyboard port. There is also an unusually high number of SATA ports, at 10 of them, besides the four M.2 NVMe. So you can also farm Chia at scale while you mine. BIOSTAR didn't reveal pricing.
