'The right to privacy matters'

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

My AR-15 ID's itself as a toaster. Want breakfast?

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 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.
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.

Hi,

received 2 samples this morning from China, but no docs and no drivers nothing, can't find anything online either, i'm trying to get it to run under WIN-7.
So far I have got the LAN to work, but thats it, limited USB, and I can't seem to ID the other hardware, also which of the pins on the fp1 is the start, and the others??

Any help would be much appreciated.

Just got one too, weirdly seems to boot happily with nothing connected to fp1, just on psu (weird bios setting?) - Most importantly - can anyone help with the start pins question?

EDIT: Weird boot aside, this setup seems to work for the fp1 pins: https://dynamize.blogspot.co.uk/2009/04/step-8-connecting-front-panel-header.html

the board is solid

I purchased 1 sample then 10 then another 10

so 21 boards 1 dud

and I believe the buyer forced a ddr3 stick into it first then the correct ddr4

there are more then one build with it on my thread and here is my youtube on it

https://www.youtube.com/watch?v=eLtnz9ip3o8

https://www.youtube.com/watch?v=feXukc1d39Y

https://www.youtube.com/watch?v=YjIG9oebnW0

the seller allowed paypal.

about 180usd for 1 sample

about 1430usd for a 10 pack

here it is with extra fan cooling

You will find them on eBay but most ship from China still.

Are there any trustworthy sources for that mainboard that have a lower min. order quantity? I never ordered at alibaba, can you negotiate with the sellers about quantity?

Another alternative is the Octominer B8PLUS board that has 8 full size PCIe slots and an integrated Intel Mobile 3855u CPU.

Mining in windows in general is asking for trouble. Almost as much as buying random weirdo untested chinese motherboards when there are a ton of compatible boards out thre in the wild already. Is there any reason you guys are going for this janky looking junk instead of buying a known working board?

if you say its because of cost, count the downtime you are having trying to get that junk working and see if you really saved much Wink

I use Windows 10 to mine and I have no problems with it. But let's not start a holy war there

All my motherboards so far are known brand ones. I have already be beaten up by issues with raisers though, and I want to try a build for 8 GPUs with no raisers. In a previous life I put together many PCs with Chinese generic motherboards and although sometimes they cause trouble, my experience wasn't that bad. As I do this as a hobby, I like testing different setups and experimenting.

...I hear you, I'm mostly done under Win 7.1 , what I did was once the MOBO was on the LAN, i used Remote Desktop to "run" the updates in a sudo headless mode, also able to copy/past drivers from host PC... 1st 1080 running up while updating the OS, so far so good!

I'd use Windows 10, you are setting yourself up for a life of pain

I purchased a new ONDA B250 D8P Ver 1.00 (the 12 slot board) and got it up and running easily. It ran with 6GPUs for just over two full days and then tonight it seems to have just died while it was working. It won't boot or post and never even wakes up the display now.
I reseated memory and pulled the battery and put it back. Also tried a new USB stick that boots in another board fine. No lights ever light on the ethernet port. No dice.

Any tips on troubleshooting this board?

Windows ? Or smos?

I run smOS.

Try only 1 card. And if you use smos make a new usb from the start

Also try a new high quality cat 6 or cable

Lastly tap the top of the Ethernet jack with your finger nail like a woodpecker taps with its beak like 35 times

Thanks for your suggestions but no dice. Even the woodpecker tapping didn’t work 😃Any other ideas?
I am using ethOS.

Purchased one last Saturday. Will be used for a 12 gpu rig running SMOS and will update once I have it set up and running.
