Octominer B8PLUS 8 PCIe Slot Mining Motherboards

27 Jan

There is an interesting new Chinese company called Octominer that is apparently focusing on the GPU mining market by offering a specialized mining motherboard for 8 GPU mining rigs. The Octominer B8PLUS motherboard has 8x full size PCI-E slots spaced decently enough to eliminate the need to use PCI-E riser boards. The manufacturer suggests that the motherboard is suitable for any Nvidia or AMD GPU that is 4.5 cm or thinner, so all 2 slot thickness cards should fit, 2.5 slot cards might also fit, but very tightly and there could be some trouble with cooling them. Furthermore the motherboard comes with integrated Intel mobile CPU with built-in graphics. The motherboards uses SO-DIMM DDR4 memory and comes with M-SATA slot for an SSD memory and a sATA interface for an external HDD or SSD drive that you need to buy separately of course.

Octominer B8PLUS Specifications:
– Motherboard: support 8x PCI-E 16x slots for GPUs
– GPU: Embedded 6th gen Intel Celeron Processor 3855U
– CPU cooler integrated on the board
– Supported GPUs: 8pcs AMD470/480/570/580 or Nvidia P106/P104/1060/1070/1070TI/1080/1080TI
– Memory: Support SO-DIMM DDR4 up to 8GB RAM (Laptop memory)
– Ports: 2x USB, 1x VGA, 1x RJ45 Network
– Power: Support server style power supply and ATX PSU
– Board dimensions: 46 X 18 cm

The price of the integrated 8x GPU mining motherboard from Octominer is currently USD $199 with shipping from China (shipping and import taxes and VAT not included). Shipping is with DHL Express and should take about 5-7 days according to the website and cost you $25 USD for most locations, though the price may vary for some regions. Octominer is currently accepting pre-orders for the motherboards with deliveries expected to start shipping by the end of January or the beginning of February, so not much wait, though shipping may not be immediately after you order.

Couldn’t put a actual socket on the board, huh…

Since it is a low power mobile CPU it is probably just cheaper and easier to solder it directly than to use a socket.

The motherboard is apparently intended to be used as is as a cheaper all-in-one solution and not for users that might be interested in doing upgrades or having a lot of options to play with.

Slots are too close together. Maybe next revision will fix that. Avoid for now.

Slots not too close. Depends how you cool it.
Test rigs running GTX 1060 , stay at 56-64 C with quiet fans and with the Delta fans even lower.

Slots absolutely need a bit more spacing (1/2-1 inch?) for something like 8x Zotac 1080Ti Amp Extreme… How could they not see that coming? Ugh. Looks great otherwise. Will buy next version if they fix that.
