Man, releases of many-PCIe motherboards have really come down to a halt in the second half of this year...

Anyone: any new motherboard release?

Edit: I think the screenshot showing "A3207" is a typo, and is meant to read "A3206". Edited the topic to reflect that. Looks like redtheminer spilled the beans first: https://twitter.com/redtheminer/status/1024307705006022657

Innosilicon A1 was No. 1 btc Asic in 2014, independently developed by innosilicon, who subsequently developed A2 to A6 various leading performance mining asic in the world.
You say A2 to A6, but I don't think you guys ever released the A3. It was supposed to be a Bitcoin mining chip succeeding the A1... |

I added the RebTech 8GPU-MB:  Very interesting product and company. RebTech seems to have existed since 2015 ( http://rebtech.ro) but they are now designing their own motherboard and even a custom GPU and they are advertising them on a new website (domain name http://rebtech.ai bougth 2 months ago.) The mobo is very compact and has 8 PCIe slots exposed as USB ports (no need for risers on the mobo side). And RebTech also made a custom GPU with a USB port instead of the PCIe edge connector. So combined together, the mobo + custom GPUs (RX470 8GB) offers a completely riser-free setup. |

No new hardware released in a month? Anyone?

Thanks. Added to http://bitcoin.zorinaq.com/many_pcie/Interesting: this ASUS blog post reveals they sold "six figures" of the B250 Mining Expert. Assuming fully populated (19 cards) it means more than 20% of the estimated ~10 million GPUs in mining farms are running on the B250 Mining Expert. |

Specifically they taped out 7nm in April 2018 and final products are arriving in the 3rd quarter (p. 118) They had revenues of 1296 million RMB (203 million USD) in 2017 (page I-32). I agree they have zero intentions to abandon the Bitcoin mining industry. Working on AI accelerator chips is just a natural way to expand their business into other areas. |

there is also the MSI HF-310-F Pro with 13 PCIE slots
Thanks. Added. Based on the layout of PCIe slots present but not installed, it seems like they may have been working on an 18-slot motherboard...  |

New motherboard: Biostar TB250-BTC D+. Relatively similar to the Colorful C.B250A-BTC PLUS V20 in terms of layout and features. I wouldn't be surprised if the 2 shared designers (ODM product?)  |

It would be nice to have a complete database documenting all PoW algos (including pseudo-code). If someone feels motivated to do it, I'd be glad to sponsor them.
Can you please elaborate on the sponsorship. I understand the equihash algorithm very well, by the way. It would be very informal. Start writing the documentation for 3-4 PoWs. If it's high quality and think you have what it takes to continue, I'll periodically donate you some BTC whenever you add more PoWs to the doc ($10-20 per hour of work). |

So, no new motherboard release that I could add to the list?

Regarding the algorithms I spent months analyzing every single one to determine which were most suitable to FPGA's. I checked them all.
This research alone is a huge effort. You are very dedicated! It would be nice to have a complete database documenting all PoW algos (including pseudo-code). If someone feels motivated to do it, I'd be glad to sponsor them. |

whitefire990: really nice job in identifying & executing on this opportunity with FPGAs! I still have a bunch of Spartan6 LX150 FPGA hardware (from 2012, when FPGA-mining Bitcoin was a thing!) but I doubt this type of FPGA can be as profitable as your cards. Do you have a particular process for identifying which PoW algos are the most profitable on FPGAs? For example you implemented Phi1612... it is not even implemented by tpruvot's cpuminer. It's used by LUXCoin which is a rather obscure coin (#458 on https://coinmarketcap.com). Did you manually examine hundreds of PoW algorithms to find the best opportunities?

I got mixed up in my contact names. Sunfa, not Zrt, confirmed they have a 12-slot in development. This doesn't quite explain why a Zrt motherboard was photoshopped. I am still waiting for an answer from Zrt...
Zrt never replied. So I guess we will have to wait and see if this 12-slot motherboard is real... |

There might be a 12 slot PCIe motherboard, but I can't find who manufactures it. This is seems to be a Shenzhen Zrt Co design. I contacted them to confirm... Only one random Alibaba seller has pictures of it: https://fashionplaza.en.alibaba.com/product/60680844122-805574575/Fast_shipping_p106_12pcs_gpu_ZEC_Zcash_ETH_miner_ethereum_mining_machine.htmlHowever I have a sneaking suspicion of this being a scam, a picture photoshopped from ZRTD-101. Slots 4 5 6 (from the right) seem digitally inserted. It's a wide area with no screw holes for support (flimsy), and the PCB/component layout is too repetitive. And the entire rest of the PCB layout (even the faintly visible traces) are strictly identical to the ZRTD-101... Plus powering 12 cards with the 12 power outputs on the PCB, fed by only 7 power inputs is not a great idea, unless your cards are low power, but then it would limit the utility of the mobo...  Shenzhen Zrt Co replied to me and confirmed they have a 12-slot board currently in development. They said it will be released probably in a "few months". They said some suppliers are already advertising it (hence the photoshopped images.) Edit: I got mixed up in my contacts. Sunfa, not Zrt, confirmed they have a 12-slot in development. This doesn't quite explain why a Zrt motherboard was photoshopped. I am still waiting for an answer from Zrt... |

Thanks for the request, I added the Olike3C and Colorful C.J1900A-BTC PLUS V20.   |
