Reviewing 6-GPU "ONDA D1800 BTC" motherboard

BTC and altcoins are all crashing today, but some mining options are still viable. I recently tested a specialized mining board from Onda.

Main body: D1800 BTC mainboard
CPU: Intel Celeron, J1800
Memory slot: 1 x DDR3 memory slot, 1600/1333MHz
Maximum memory capacity: 8GB
SATA: 1 SATA interfaces, 1 MSATA interfaces
Audio interface
Video interface: VGA
NIC: 100M/1000M
USB: 1 USB2.0 sockets, expandable 2 * USB2.0 interface; 2 USB2.0 interfaces
Other sockets: 1 x RJ45 interface
Video card slot: 6 x PCI-E X1 video card interface
Other PCI slots: 1 x Mini-PCIE (support MSATA)

Pros: CPU is included. Can use cheap laptop DDR3 RAM. Six on-board PCI-E slots - so you won't need PCI-E risers/extenders. This simplifies cable management significantly. On-board VGA - which is initially the default screen when you boot (please note that some models being sold do not include a VGA adapter - so you will need to connect at least GPU for setup).

Cons: no documentation (in English). Confusing labels (e.g. power connectors marked 'OUT').

Make sure that you use 1.35V RAM like this:

Manufacturer recommends 4GB or 8GB, but I got mine to run with a 2GB stick.

If the board isn't getting to BIOS (and not powering your USB devices, like keyboard or mouse), make sure to check the following:

  1. RAM needs to be properly seated
  2. all power connectors need to be hooked to the PSU (see photo below)

In case anyone is interested, the board is currently available on Amazon, AliExpress, and also on eBay.

You can find current drivers/BIOS on the manufacturer's site here:

I will update this once the rig is up and running with multiple GPUs.

February 4 2018 update:

Added 3 GPUs so far (GTX 1060), everything is running smoothly. Ubuntu 17.10, NVIDIA-384 drivers, CUDA 9.1 + "milk crate" rig design:
