Original article, 7/24/17, 8:25am PT:

Biostar is back with yet another cryptocurrency mining motherboard, the TB250-BTC+, which is the world’s first 8-Slot PCI-e mining board.

The TB250-BTC+ joins Biostar's recently announced TB350-BTC and TA320-BTC mining motherboards. The company said this board is designed specifically for people  looking to "maximize your mining from home." According to the company, even though this board supports eight Nvidia or AMD graphics cards, the motherboard stays close to the safety limits of a continuous load rating for a typical 15amp household circuit. 

Given the fact that this board is based on Intel's B250 chipset, it features native support for 6th and 7th generation Intel LGA 1151 socket processors, two DIMM slots supporting up to 32GB of DDR4-2400M, a single PCI-E x16 3.0 slot and seven 7 x PCI-E x1 3.0 slots, 2 x PCI-E 12V 4-pin connectors, USB 3.1, and 7.1 channel HD audio. As with Biostar's other mining-specific motherboards, the TB250-BTC+ also includes a moisture proof PCB and low resistance mosfets as well as electrostatic discharge (ESD) and overvoltage protection.

As we have explained in the past, even though the Ethereum mining craze is showing signs of waning, many companies are still jumping on the cryptocurrency mining bandwagon with products designed specifically for miners.

    What are bitcoin miners going to plug into all those PCI-E x1 slots.
    I thought they were primarily mining with dual-slot PCI-E x16 GPUs.

    heck, 2 of those slots are inline with each other. I have no idea what could possibly fit there.

    For mining you don't need the bandwidth. Each card is typically hooked up using a ribbon cable.

    I believe most mining rigs (insofar as setups dedicated to mining alone go) actually have the cards suspended over the motherboard in a rack of some type, with the GPUs attached using a PCIe x16 to PCIe x1 ribbon cable.

    As I understand it, it is not a high bandwidth application since while the GPU will be utilized heavily, the actual data throughput is low as the calculations take a significant time as compared to other applications like gaming that require processing a lot of data in real-time in order to render quickly.

    Others welcome to correct me if I'm wrong about any of this.

    The cards are plugged in with a x1 to x16 riser board using either a ribbon cable (old school) or USB 3.0 cable. I have a couple mining rigs for alt coins. You should not try and mine Bitcoin with a GPU rig unless you want to just throw a couple grand away for fun. GPU mining is for altcoins like Ethereum, Siacoin, Monero, etc.

    Just google "ethereum mining rig" to see how they do it. Prepare to be amazed by what you see..

    And board footprints for four more PCIe x1 connectors. Maybe Biostar is planning on a twelve-slot version later?

    Never mind, I just happened across the TB250-BTC PRO. The twelve-slot version already exists.

    This fad needs to end or vendors need to increase GPU production capacity. The upside will be the glut of used GPUs when miners get tired of losing money on their rigs and devices start turning up for re-sell on the used market.
