Small Update: Rebar Support is not an option it needs Generation 10 CPU and that Board support only Generation 6+7, so that is a dead end.

Small Update i got a lead from reddit :
Does the BIOS have resizeable bar support? I heard that P100/P40 requires this for multiple cards to work well.
i could not locate resizable Bar Support in the American Megatrends Bios ;(
somehow i cannot add pictures here, otherwise i would have share the bios options.

I think you have something here, but probably not leading to a solution. It could be the B250 chipset. I have a Asus B350 with rebar but it's not documented in the
manual so possibly was introduced with B450 and back ported to B350 with a BIOS update. It's unlikely possible on the B250 but if so would require the update from Onda.
The Problem is, Onda is not very supportive at all, as most of these chinese "cheap,cheap,cheap" mining companys...

1) No it does not. Or at least it did not the last time I used one of these boards.
2) Is it *really* worth all the time you have been putting into this? Would you be better off getting something that is known to support it. YES there is a cost, but how much are you loosing each day not running all the cards?
3) Go to https://www.talkimg.com/ and you can upload an image there and then post it here. If you want an account react out to @joker_josue https://bitcointalksearch.org/user/jokerjosue-97582

Thanks Dave for the heads up, appreciated. currently i have a truckload of theses ondo cases sitting and catching dust. We currently deploy that batch of P100 with GPU Server that can take 8 of them at a time and work flawlessly. When i get the ondo cases working, i could deploy a second batch P100 pretty rapidly. So yes, it is worth the time, cause otherwise the ondo cases are dead in the water.

yeah, sadly they did not find a solution either ;(
It's kinda ironic, the slot spacing is better suited for Teslas than Gaming GPUs.

Just to keep you all in the loop, the Celeron theory was tested 
i bought i3-4 Core CPU, same result. i suspect the B250 Chipset and how the PCI Lanes are address is part of the Problem. Expensive Lesson for us, as we have to buy now Server ontop of the cases we got initially.
(we event tried two other different Mining mainboards, but they had also the B250 Chipsets and did not work out.)
We even were going as far as getting an Octominer Case, but that did not work either. Only working solition so far was a professional Server System.
Is it works with riser? i bought i3-4 Core CPU, same result. i suspect the B250 Chipset and how the PCI Lanes are address is part of the Problem.

Is it windows?or? Driver?
it is on bios level, and no riser do not work either. we stopped the efforts on this one, we bought professional Server now.

Did you leave first PCIE slot empty, like I told you, this link has solved similar problem to yours with this MB

Not every celeron cpu is good for multi gpu mining. I remember from eth mining days when I bought wrong celeron for my 19xpcie motherboard. Celeron G3900 works with multiple (8+) gpus at x1 pcie.
Do not use first pcie slot, IMPORTANT it is x16 and it uses up most pcie lanes.
TLDR: DO NOT PUT GPU IN FIRST SLOT, LEAVE EMPTY
If you are using an x1 raiser, then there should be no problems with 8 video cards on a regular motherboard. And you should also not use NVMe drives.Do not use first pcie slot, IMPORTANT it is x16 and it uses up most pcie lanes.
TLDR: DO NOT PUT GPU IN FIRST SLOT, LEAVE EMPTY
If there are more video cards, then it is better to think about buying another processor in advance. But for me, the ideal number of video cards on a motherboard is 6, so that consumption is no more than 1 kilowatt per hour.

This makes sense, though using a Celeron for a large (> $5k) GPU rig is too minimalist IMO. Spend an extra $100 for a i3 or i5.
In this case there is still the issue of it being Tesla GPUs. They have much more VRAM to support and may have minimum lane requirements.
I'm not speaking from actual experience. I expect a motherboard designed for mining would work out of the box in most cases. The unknown
variable seems to be using Tesla GPUs in a large rig. It's also possible Nvidia deliberately borked Teslas to require higher end platforms. After
LHR I wouldn't put it past them.

1.Try with risers:NO
2.Change motherboard

I wish I had read this earlier. In such cases, you usually need to change the motherboard and processor. Many Tesla P100 video cards do not work on all older platforms. And for old video cards, your Onda B250-D12P-D1 Motherboard will still be relevant even with a old Celeron.
March 24, 2024, 02:25:21 AM
I gave up and moved to a IBM Server System looks like everything with a B250 Chipset and PCI-Lane splitting will not work for the P100, sad ;(

Bigger CPU is coming in today, but 4-Core is the max. for that board anyway. Bios update is not so easy, as i could not find any newer bios at all.
