Onda B250-D12P-D1 cannot boot more then two Tesla P100 -16GB Cards - 100$ Reward

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?
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.

Different Tesla,  same problem.

yeah, sadly they did not find a solution either ;(

It's kinda ironic, the slot spacing is better suited for Teslas than Gaming GPUs.

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.

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://bitcointalk.org/index.php?action=profile;u=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.

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...

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.
