I have one of these boards and it will only detect 3 GPUs no matter which slots I use.
The setup is using a 1600 EVGA PSU, 5x RX480x, I also tested with RX 580s same issue. It is weird, all the molex and SATA power connections are plugged in and operational.
16gb of Ram and an i5 CPU.
Boots fine yet only 3 of the GPUs power up. The rest do not power on. I have tested with 3 PSUs same results.
Anyone have any ideas?

are you powering pairs of the molex/SATA plugs independent on their own cables, and all of them? I know they are specifically for powering most of the 16x and all of the 1x slots. I know GPU slot 1 (and possibly 2) share with the CPU from what following the traces on the board have shown me... Its been a few weeks since i've looked at it. |

I have all three molex and SATA power cables plugged in, each with their own cable from the PSU now. I did have them all plugged in but sharing 4 cables for all 6 ports. After going over everything and taking one shared molex that was powering 2 ports and gave each their own cable. So what I have now is this. Slot 0,1,5,6,7 all will power up GPUs but slots 2,3,4 will not. Any GPUs placed in 2,3,4 will not even spin up fans. The same GPUs work in other mainboards and even the working slots on the board. Now of the five slots that work 0 will not go above 190 mh/s on XMR, slot 5 will mine then hang. Slots 1,6,7 all work ok for some reason. It does not matter I have tried all sorts of stuff. The thing with all these cards is I took them from a working system using a TB 350 Pro with a Ryzen cpu. I wanted to try the Onda B250. I am surprised that it is not just working. It seems fairly plug and play with SimpleMiningOS. I have one of these boards and it will only detect 3 GPUs no matter which slots I use.

have you tried just one gpu; rotating slots one at a time to see if its just the slots causing the problem?
What cpu? (just for knowledge)
Have you tried any BIOS setting changes? I'm pretty sure its supposed to work right out of the box.... so not too sure about this being of help. But who knows, maybe.
If I can help you find a solution, I will.
I have a populated board with no video cards to provide as a test-case if need be.

I am running 8 1080tis on mine doing 5100 sols. If I could get a 2000 watt Corsair I would crank it up more as I know I can pull 5500 sols on it. The 1500 watt let’s me run the 1080tis at 150 watts each. I have 7 Evga hybrids and 1 zotac mini this pushes the corsair ax1500i psu hard here they are on smos and a video Your video will be live at: https://youtu.be/1hZ0U1x_uZo |

I found this with win10, but SMOS was/is awesome. Lord knows what the difference is (apart from the obvious)... |

I am going to dig around the bios as those three slots dont work even if there is only one card in the system and it is in one of them. I have tested with a couple of my server GPUs as well with the same results. It is weird it is those three. have you tried just one gpu; rotating slots one at a time to see if its just the slots causing the problem?

I agree I really like SMOS too. In fact I use it on my Antminer G2, I get better results than with Windows or the CentOS that it ships with. My only complaint with SMOS is that it does not yet have the ability to save configs as you change mining clients but he has that coming.

At least that's progress on figuring it out. do you have expeirence with an ohmmeter and doing trace continuity checks? I can take some measurement son my board, and see if yours correlate..... maybe we can find the component that has a bad solder (what I would expect to be the case) Oah and another good thing to try: use a powered riser on each one of the three slots with a single video card; see if its the slot power (which is what it seems) or if its the slot PCIE lanes that are knackered. |

I can get out my ohmeter and check the traces. That is a good idea with a riser test as well. I will let you know in a bit. Thanks again.

By the way even though it does not really matter here is the CPU and Ram I am using. Intel Core i5-7500 LGA 1151 7th Gen Core Desktop Processor (BX80677I57500) Mushkin ESSENTIALS Series – DDR4 DRAM – 16GB Memory 2Rx8 Single Module SODIMM Both we rated compatible and show up fine in the BIOS.

Its definitely the board. The three slots do not power up cards even with risers and on the fluke meter several traces never get power past a certain point. I will seek a new source for the boards.

Now this rocks. Nice work Phil. It is a pain to even find two of those cards, I still have to get a few Nvidia chipset cards to use. So far I am all AMD. I am running 8 1080tis on mine doing 5100 sols. If I could get a 2000 watt Corsair I would crank it up more as I know I can pull 5500 sols on it.

if the old board is bad/damaged, I may be able to figure out where the missing link is and add botch-wires to fix the broken/open traces.... but something inside my head says its probably a bad solder on a choke/capacitor or something in the link from the molex/SATA to the PCIE slots (their solder flow job is definitely minimal).... either way, if its just power missing, it should theoretically be repairable... Having a functioning D8P board, I could compare traces to find the fault. A powered riser didn't allow the machine to see a card plugged into it? If so; This itself would probably be the worst case because the PCIE lines themselves would be bad; but wince the power didn't even make it to the PCIE slot, I am willing to gamble that that my main theory is the issue at hand... www.cryptomined.com sells the D8P, as well as fully enclosed (and rather nice might I add) cases specifically for the D8P. I think they also have a case that can handle all 12 GPU on this board. |

It is definitely something that effects the PCIe slots. I even tried a PCIe network card in them and they did not power it. I sent it back. Phil hooked me up with a new one. It will be here soon. Cryptomined comes back with an error. I am going to get one of the Spotswood open air cases for it. I did see some cases for them though that looked great and would handle all 12 cards. That would be fun to have especially since it fit in a network rack.

So I have GPUs in slots 2 - 8 on an Onda D8P board (directly in the slot, no risers).
The board will only recognize the GPU in slot 2. I don't have anything in slot 1. Does this board require something in slot 1?
I hope this isn't a case of another bad board. I have yet to try the one working GPU in other slots, will get to that in the morning.
I have 2 x 1800W PSUs connected. One powers the first 3 GPUs and the mobo, the other powers the last 4 GPUs. All GPUs are 1080Ti.
Any ideas?

No, it'll be fine without slot 1 filled (the short slot blocked by the MB power cable right?). Have you tried just using one psu for the mb and three gpu, then adding the rest? I dunno about dual psus for this board... |

Since I’m waiting for my warranty replacement for my octominer motherboard I went ahead and ordered a Onda B250-d8p-d3 which is the newer version with only 8 slots and none of the extra ports. It also has a completely different layout for the connections that will no longer interfere with your first card. I will testing it vs the octominer and will do a full review of both. I’m hoping this Onda will fit in my octominer case. They look like they are based off the same pcb so fingers crossed.

Cool, I look forward to seeing how that one works for you. I have a spotswood case on the way so I can adapt as needed if they change the layout. By the way big thank you to Phil. He got me a new board and it is working great. Thank you Phil.
