OUTAD

OUTAD B85 8-card Mining Motherboard LGA 1150 Intel

SKU CH-1MRM-XEW92

An extended-ATX LGA 1150 board with eight PCIe slots spaced 65 mm apart, B75 chipset, all-solid capacitors and a 100 Gigabit LAN port

  • CPU Socket TypeLGA 1150
  • Supports eight graphics cards simultaneously
  • 65 mm spacing between each card
  • B85 chipset with all solid capacitors
  • Onboard 100 Gigabit network card included
  • DDR3 notebook memory slots provided

Mining motherboard with eight GPU slots

The OUTAD B85 board uses an LGA 1150 socket and the Intel B75 chipset to host up to eight graphics cards in a single extended ATX form factor. It targets miners and compute-cluster builders who need maximum card density on one platform without riser cables. No onboard audio is fitted, but a 100 Gigabit network controller is integrated.

PCIe spacing and lane limits

Each of the eight slots sits on a 65 mm centre-to-centre pitch, giving physical room for thick dual- or triple-slot coolers such as the 3090. The chipset provides a finite number of upstream lanes, so every additional card shares bandwidth; eight cards cannot all run at full electrical width simultaneously. Stability relies on the all-solid-capacitor power delivery across the extended PCB.

DDR3 memory and card headroom

Two SO-DIMM slots accept DDR3 notebook modules, limiting total system memory to the capacity of available sticks. The board powers and detects mainstream mining GPUs including the 1660, 2070, 3090 and RX 580 across 10, 20 and 30 series families. Builds needing more than eight cards or full x16 links per slot must use additional host systems.

商品問答

Will the 65 mm card spacing on this board let me fit eight full-size graphics cards without riser cables?

The board is built with a 65 mm slot pitch so eight double-slot cards sit directly in the PCIe slots, eliminating the need for riser cables and reducing connection points that can fail under continuous load.

Which memory type do I need to populate the RAM slots on this motherboard?

The board uses DDR3 notebook memory modules, so you must source SO-DIMM sticks rather than standard desktop DIMMs.

What CPU generations are compatible with the LGA 1150 socket on this mining board?

The socket supports Intel Core 2nd and 3rd generation processors, giving a range of affordable used CPUs that keep power draw low for mining rigs.
