Hello guys,

I discovered a chinese motherboard, made specially for mining

The motherboard is named "Onda B250 BTC-D8P", and has 12*PCIe onbard. 8 of them are full size, so you don't need risers to make it work

I have lots of difficulties to find some information about this motherboard, and nothing here : does anyone have tried this motherboard ?

Seems very interesting

Check out this thread. A few guys have already built rigs with it and like it:

https://bitcointalk.org/index.php?topic=2138550.msg25225604#msg25225604

philipmain 1957 may have some available.

Thanks for the tips, seems really interesting ! Quite strange no one talks about it here

Does any buyer have feedback to share here ?

See the thread mentioned above, lots of testing and talk about it (and similar boards earlier in the thread too)

i am looking to import them to the UK and was wondering who would be interested in them. I have heard great things of them and the best bit is they do not require risers.

Sweet. That would be a nice board for my next build. Just noticed tho that it no longer includes the built in CPU or the mobile laptop RAM compatibility. The previous version ONDA1800 had those features. I wonder why they dropped it and went with a regular CPU and DDR4 RAM.

Too bad you can't order just 1 piece because the minimum is 10 and you still have to bid. Anyone want to do a group buy? Lol

They do the CPU and Ram on the 8 gpu version not the 12 :)

Good looking motherboard but the price can be cheaper.

can u tell a reliable sourse to buy this and the 8GPU version?

up

There's a few feedback in the thread mentioned above, but not enough in my taste

Someone to post a full review here ? :)

IMO the biggest issue with the board is the spacing of the slots makes cooling marginal on higher-powered cards.

up

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
https://bitcointalk.org/index.php?topic=2138550.msg26678847#msg26678847

I would be interested in one at least, I saw this board a few days ago in some video and I think they are a great idea.  I was looking around to see where I could get one from.  If you end up stocking them, let me know!

Hi philipma1957,

I just bought 3 Onda B250 BTC-D8P and tried using it for simple mining os but it keeps hanging, I also tried it on ethos and kept getting kernel panic errors once I tried to install more than 1 gpu.

Could you advice me on your bios settings for this board and what I should do as I now have 36 rx580 8gb gpus and 3 of those boards that I am still unable to mine. Thanks, I have also dropped you an email, really hope you can help me on this, would love to talk to you and hopefully you can share with me your knowledge on these boards. Would really appreciate it. Thanks

I'm not philipma but have you considered using win10 build 1709? it can support 12 AMD GPUs now without problem.

---

Am I missing something or am I only seeing 8 PCIE slots instead of 12? Checked the link aliexpress webpage too but still can't see 12.

Hi philipma, would you happen to have 1 more ONDA lying around? I'm interested in buying one from you.

All my boards use nvidia cards  and smos for nvidia

unfortunately I have no boards using AMD cards and I no longer use amd cards to mine as they suck for the most part due to issues like yours.  In fact  the one guy that setup  amd cards on our thread had more problens with his board then anyone else.

I have used all of mine or sold them and have 0 spares.  it has 8  full slots  and 4 slots for risers

if you want access to all  8 full slots and the 4 risers you need to use shorter cards  like the zotac  1070 mini

Since these boards are so cheap compared to the brand named ones.
I would guess they don't have wifi capabilities built in.

Which motherboards have this available to them for adding 8+ gPUs?

for first start  do you know how to short  mobo pins? or use this

https://www.amazon.com/Electop-Power-Button-Computer-Switch/dp/B01LMZZFWO/ref=sr_1_1?ie=UTF8&qid=1515199592


also   did you plug in an atx psu  with

the 3 sata and the 3 molex connected

I'm sorry for my English.
Phil, can you show photos of your rig with GPUs and wires?
I don't understand what 6 power sockets do in this board and how to supply the board by psu without 24pin socket.
Thank you.

I don't understand what is 6pin connectors do. They are used instead 8pin GPU's connectors?
I would like to make my first rig and collect all information for it in the internet.
I would like to use this motherboard, but ver2 with 8 pcie, 8 gtx 1080 ti and psu. And I don't understand which kind of connectors I need.
An ordinary board needs one 24pin, one 4+4pin and nothing anything. But this one has above plus 6 6pin.

My older ver with 6 PCIe is going to be here next week. Will update with AMD GPU results.

Thank you Phil for sharing, highly appreciated.

Same thing for me, I have 6 PCI-E connectors instead of molex and sata connections. Also, they state ddr3 memory but looking at Voskoin video, seems he used DDR4. Stange as DDR3 and 4 don't have the same key for installation...



Any advice?

Any feedback on the board so far?

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

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.

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

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.

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

...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!

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  ;)

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.

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.
https://bitcointalk.org/index.php?topic=2754227.0

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

Hi, please tell me the supported processor and ram. Thanks a lot.
Newbie here :)

missed it I use this ram

https://www.amazon.com/gp/product/B015HQ9UDO/ref=oh_aui_detailpage_o00_s00?

this cpu

https://www.amazon.com/gp/offer-listing/B01N1SH3PB/ref=dp_olp_new_mbc?ie=UTF8&condition=new

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

Mine is working perfectly I just dont realise how to connect the power button (I turn it on and off through the main PSU)

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.

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


https://i.imgur.com/ZGvdnVs.png

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.

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.
Phil do you have any left?
Thanks again everyone for the help.

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.

Pm sent

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.
Thanks for the help.

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.

I have both, size is a little different, separation between cards is a little bigger on the Onda too.

yeah, id say the slot spacing on the onda is 2.2-2.25x the standard spacing.   There's enough room to fit an EVGA with its massive super over sized cooler and still have room to breathe between cards.

Does anyone know the nominal and max power (watts) that is drawn through each of the 3 molex ports and each of the 3 sata ports on the D8P if only slots 1-7 are occupied (slot 0 empty)?

Reason I'm asking is because I want to run 2 PSUs to this board and I'm trying to decide the best way to split power between the 2 PSUs (1800W and 1200W) with all 8 PCI-E slots occupied.

Are most of you guys using the original Onda board hat has the 12 gpu capability or the new one with just 8?

https://imgur.com/a/CSqXH

D8P, v1 (12 gpu).  rock solid. short gpu required for slot 1. only running gpus in slots 2-8 for now.

8 gb gskill ddr4
celeron 3930

I do with a few and try to make sure each psu is powering the same card(s) through both molex/sata and vga, so if one psu goes down there is not a card being powered only through the pcie slot molex/sata--but this suggestion came to me when I jumped psus rather than add2psu connect, with risers where the sata adapter to the riser could melt if a different psu to a card went out and the card was trying to draw 120 through a cable rated for 75. In my experience wiht onda b250s if the sata/molex to the board is unplugged and the card powered, it's just not picked up, and vice versa.

Have guys found any closed/server style cases for the Onda boards?

Yep.

quick google searches my friend..... (https://www.cryptomined.com/index.php?main_page=product_info&products_id=361)

 I’ve seen that one, I asked in case someone had come across anything different. /salute

Spotswood on this site makes an open-air frame for them....

I have the spots wood for the eight + four board

I consider getting a second one

I have one of the Spotswood cases on the way should be here next week. Going to be fun.

any other GPUs connected?

Do  you have both the 24-pin power cable and the 8-cpu power cable connected?

DDR4, I assume?

Dunno, I'm running 1.2V DDR4 on both of my boards.  Does this board require 1.2V memory?

Also, double check CPU and memory seating.  Check memory contacts for any tape/glue.

This main board is really stable so far. I have an i5 CPU and this for ram.
https://www.amazon.com/gp/product/B019A81BIW/ref=oh_aui_detailpage_o02_s02?ie=UTF8&psc=1 (https://www.amazon.com/gp/product/B019A81BIW/ref=oh_aui_detailpage_o02_s02?ie=UTF8&psc=1)

I really like the Spotswood frame too. Easy to setup and works great.

For a short test, Ill be using one of these as a mining and gaming machine at the same time........  Just to see how well it can handle it.

My mSATA and cpu cooler arrived today, so finally time to populate and power this puppy up.

good  so win 10  with the i3 I sold you   if I recall .

 what size ram?

I messed around running games on an 8 GPU rig last summer. It was fun but it seemed like the games could not even close to use all the power of all the cards.
Have fun, I look forward to your results.

My 2 ONDA D8P boards are running rock solid. I have no complaints.

I just wish I understood how much power was sucked through the 3 SATA connectors and the 3 molex connectors on the board for the purpose of dividing PSU power in a multi-PSU set up.

Is it sold anywhere else except for Aliexpress and Ebay (where same sellers sell same stuff)? The idea of waiting a month for the mb to arrive isn't very appealing.

I have 1 left new.

Are you USA based

It fits in a usps game flat rate box

I can ship it on Monday .

Do want to run Windows or smos Linux?

Windows use a i3 or better with a 8gb stick of ram.

Linux use a celery stick and 4gb ram

FYI, I'm using Celeron 3930 with no issues.

Phillip, I'll take it if he doesn't want it.  PM me if applicable.

8Gb Ram it's 1.2v.  I went to frys.com and looked up ddr4 sodimms that were in stock;  and made sure in the description it only showed 1.2v.  I ended up buying Patriot Viper 8Gb PC4-21300 2666MHz; and yeah, the i3-6100.  Right now its finally through it's windows 7 install->update-win10 upgrade.   I put a 64Gb mSATA in it.      Works like a champ.

Next is to put a real power supply on it (presently using a pico PSU on a +12 barrel plug; and the onboard gfx port) and populate each slot one at a time, as well as get the nvidia / amd drivers installed onto this drive.    Once everything is verified working; Ill image the drive as a fail-safe clean-reset for my D8P in the future.  
Not sure if others could use it as the windows license may be tied to the drive serial...  They would have to activate windows on their own.  But ill have a base point for a windows 10 image for mining for myself regardless.

I need a case for this thing;  I responded to spotswood's thread, but haven't heard from him.   Id rather have a case like the one [i believe citronick] is using... the enclosed metal case.  There is even a version that has provisions for risers and 4 more GPU.

Right now;  Its running off a pico PSU, and a USB wifi card for internet access.  It's doing XMR on the cpu, maintaining ~50*c....   Until I get GPU's on it (and it in a case), it will probably sit like this after initial setup with drivers.

Im having trouble with figuring out the right driver/combo for AMD to get good hashrates on ETH, XMR and other algos combined in one install.   Making progress...  Just annoying as #@$^ cause it feels like you are going in circles sometimes.

I'm based in the USA and have 9 of these boards in stock.

I test these for working condition before shipping.

I use a G3930 for the CPU

I use 4GB 260pin DDR4 for the RAM - model AD4S2400J4G17-B

PM me if interested. These can ship pretty quick and are less expensive that what is typically found on Ebay and Amazon.

Edit: Spelling

Thanks mate but atm my interest is more in "general knowledge" field. I need to buy 4 more 1080TIs to fill the last 12xGPU rig I built, then I will look at MB options for the next one :)

Im having the strangest of luck.  Maybe its because windows was installed off the integrated GPU?

My onda board works fine.  All PCIE slots respond;  I can see POST display on all of them when tested one at a time;  but once it goes to boot past POST;  its just a black screen.  With any GPU installed;  the onboard graphics do not respond or show a POST at all.

I still need to try a DVI port on the pcie gfx cards to see if that gets response;  but since the display is still lit and blank;  I think its not the case.

If at any time I remove all PCIE graphics and plug back into the built in HDMI port;  it boots up and works as you would expect.


Kind-of annoying....

Anyone else run into this kind of issue with the onda board???

I got four cards to work with Windows 10 .

But I only could use the gpu on board.  I think it was 8gb ram and a i5 7400t

I installed Windows off the integrated GPU and didn't have issues. Why are you trying to view video from the PCIE GPUs?

Do you have all the molex and Sata power cords connected to the board?

Did you just install one GPU and try a boot?  The IGPU should still control the video.  Then install the driver and reboot.  The PCIE should show in DM.

Then you can add one at a time or plug them all in.  I did it both ways on my 2 boards and all the cards were recognized either way.

What I did:

used integrated graphics for the start.  i3-6100, 8gb ram, 64gb Msata.
installed 7;  updated to SP1.  Upgraded to 10 free.   Updated 10 all the way to 17xx;  no more updates available.
Used windowsupdate driver search to install the other peripherals (smbus controller, etc)  As well as the onboard intel video driver.

All good so far.    Can't install the crimson blockchain driver cause no device is present.  Can't install the nvidia driver cause no device is present.   Totally normal.  I can run xmr-stak fine on the CPU.... all is good.



Now; This is with a 1000w PSU, and all power plugs on the board populated correctly mind you.

From here:
Simply plug in a GPU;  and onboard graphics no longer POST.  if I plug the HDMI into the video card;  Ill see post there, but then after post nothing but blank screen.  Via the HDD status light on the msata drive;  it looks like its booting into windows.  Can't see anything past that.  If I plug the GPU into slot 2 instead of slot 1, same exact results;  post seen on GPU, but nothing but a black screen past POST.  The monitor does receive a signal of the right dimensions (1366x768); but nothing makes it there from windows.   effin strange.

I tried plugging in anything form a GTX470, 650, 550, 650ti, 550ti to a GTX980.... nothing, same results.

unplug all gpu and hook to onboard HDMI;  works as it did originally.

Try installing windows 10 clean.

not an option.  I need to install and have it online for a month or two before I can do a clean install.  This way my hardware profile is present on the activation server for next time.  I have yet to have an issue with a 7->10 upgrade that requires a clean install.


What I did try, and seems like it may be working, is change BIOS primary graphics setting to IGFX; and it booted to windows on the internal graphics with no issues while a card was installed.   I am attempting to install the driver now.  Strangely windows didn't show it as a GTX650;  it called it a basic display adapter.   Uaually it ID's it's model at least.

Anyhow;  I will report back once I get more done.   Hopefully I can get this thing running XMR on my old GPU pile to fully test it's multi-gpu capability in windows 10 tonight.  Hopefully I have enough power left on this circuit to do it safely XD.  These old GPU's pull a lot of juice;  especially the GTX470.

Hmmm, IIRC, the BIOS on both of my boards was defaulted to IGFX.  I thought about that, but didn't mention it because I thought it was default.

Well, I'm pretty sure that's your issue.  Good luck!

Yep success.

Currently up and running mining XMR with 3 GPU, and the CPU.  I need to shut down my rosewell machine and yank the two cards out of it to populate it with 5x.

5 cards no problem.  gonna try some more later today.

470,550Ti,650,650Ti,960SSC   =)  Breaking out the old guys for this test.

Very cool. I am liking these boards. They run stable and are dead simple to setup.
I look forward to your results on some of those older cards.

They all worked like a champ.  Installed a driver for the 470; and it was able to handle all the cards except the 960.  for that I needed to install it's nvidia package as well.

Broke out a GTX275;  no dice.  Driver is too old and doesn't play well with the newer GPU's in the system.  Always Code42.   No bother on that GPU.

as far as miner apps:  There's very little available.   I've been running XMR-stak on the ONDA since its been on.   It can utilize all the cuda GPU's because it uses its own library DLL/functions;  not "cuda ver X" you have installed and available to use.

Each new GPU you install, you must boot to windows, and wait for all the device manager operations to finish before proceeding.   I always reboot before mining.  Just to make sure configs are saved for the pcie bus in the HAL.   Simply swapping 2 cards positions makes the system freak out and need to reconfig itself.

So far;  aside from the known that the 470 is a heat-pump;  (and not having my kill-a-watt meter) It's been pretty stable.    I like this board.   Very much.   Ordered a frame from Spotswood and submitted payment yesterday I believe.    I am using a 80Plus 1000w power supply on it presently, but Ill probably swap that one out for my coolmax 1600w. 


I've been saving $$$ and have a bunch of friends who owe me cash as well, so when the new card generation hits the shelf, I am just going to buy and populate this thing.   The last two times, I should have, and lost out big time....    I don't mind if I loose out this time, cause Ill have some shiny new hardware in my hands anyways.

Hello guys, I  got few rigs set up on this Onda B250 D8P motherboard and all share the same problem - everything works great on every possible setup, except when you put card in 1st GPU slot(the 16x one), then it gives out constant 4Mh/s from a GPU that is in the first slot and other cards get unstable hashate(keeps jumping up and down), which also gives SMOS monitor wrong info on monitoring. It works perfectly on a  7 card setup with 1st slot being empty. Works also great, when using 8 cards but one card is plugged on the small pci-e port thru a riser(again, 16x slot is empty). So my question is, are there any BIOS setting I am missing, or something else? I can already say that it cannot be a faulty board, since more than 10 rigs share the same problem.

Using SMOS, mining only ETH w/ AMD rx570 gpus,  1650w psu, celeron g3930(iirc), m.2 ssd.
If you need more details, let me know, been struggling with this for a very long time already
Any help would be appreciated, thanks in advance!

8 x 1080 TIs work fine for me with this board...

I know it probably has nothing to do with your problem, but the onda D8P doesn't have an M.2 slot....

Very strange its only the first slot, but its on all boards... so that part makes me curious since its pretty much not reasonable to happen.

I had the same problem. change mode I think this solution.

i have 230 cards.

Sorry, my bad. Wanted to say mSata slot

Thank you for answering.
What do you mean with "change mode"?

I finally got around to putting 8 gpu’s into by newer 8 gpu version Onda board. I plugged in 2/6 6 pin connectors on the motherboard but only 4 of my 1070 ti’s will power up. Do you really have to plug in all 6 and then plug in 8 more for the cards? That’s just ridiculous. Even my 1600g2 doesn’t have enough connectors without ordering splitters or extensions. I only needed 2 6 pins on the octo board, I can’t think of any good reason to require all 6 when your directly powering the cards anyways.

Am I missing something or is this the actual requirement?

GPU's can draw up to 75W through the PCIE slot.   they need juice.... gotta make it available to them.  if you are populating all 16x slots, you need ALL extra power plugs plugged in.... as the 16x slots don't get power from anywhere else.   some 16x slots share the same molex/sata port, but, in general, they are necessary to plug in.

Remember, only two plugs per PCIE cable or per SATA/molex cable.
if using a SATA cable;  you could try one splitter and powering 3 ports;  but I do not recommend.

These boards do have hefty requirements to fully work.

That isn't the case for the Octominer board. You only need 2 of the 6 pin connectors on the board for power even with 8 gpu's. I guess the Onda is different, but its definitely a hassle from a connection stand point.  I still like the Onda board better for windows operation though as with a g4400 cpu its so much more responsive than my Octo board.

I have to say I am really liking this Onda B250, it runs great no matter what I throw at it. Simple Mining OS, Win10, Debian. They all just work. I currently have 7 480X 8gb cards in it. I had 8 but one died, it will be back from RMA in a few days. It worked great when all 8 were in there. Starting to think I should buy one or two more of these instead of wasting time messing around with other boards.

another facet:

If you accidentally bump the BIOS reset when plugging in a USB (keyboard/mouse in my instance) all you need to do is F1 into BIOS, and set default graphics to IGFX....    simple.

But yeah, im loving this board.    It's the perfect format IMHO.

Bought some 6 pin extenders and just used the unused 6 pin off each of my gpu cables to fill the motherboard 6 pin slots and everything worked like a champ. 8 gigabyte 1070 ti’s running with no issues. It did bump the power usage up a bit compared to the same setup on my octo board but not enough to be an issue.

Huh?  The B250 D8P doesn't have 6-pin slots on the mobo, at least version 1 doesn't....

Oh wait, you're talking about the Octominer board?

D8P V2 has 6 pin PCIE power replacing sata/molex, as well as a repositioned ATX power port..... from what I recall.

Good to know. I have not done much with the bios other than a quick look.

just got the same problem. With all my motherboards. Long time lurking and the fix is:


1) load bios
2) system agent
3) gpu settings
4) port 1 was set not like others. just set the same settings for port 1 like for others.

Thanks, this has been a savior for me. I spent hours debugging the same problem as well.

I know what the specs say for supported CPUs, but has anyone tried an 8th Gen 1151 CPU in this board?

B250 does not support 8th gen;  same socket, different pinout.

Its sound like good motherboard. Simple but worthy. Cheap but not cheaper. I have use it for a long time and until to day its not get some trouble. But remember do't to push it too much and don't forget to keep clean it. Happy mining bro/sist with it. :)

Wow thank you 100x .  Spent all day looking for this solution.

If anyone is having trouble on the v4 motherboard just look for port settings and match port 1 settings with port 2 and 3 (set everything to auto).

Im new to the mining and computer building in general.
Been learning mainly from youtube.

Ive order 4 Onda B250 boards from alibaba with 1650watt PSU

CPU G4400
Ram 4GB Sodimm.
GPUs RX570 4gb
SMOS intended

this is my first rig build or computer build.

ive installed CPU, Ram all power including 3molex and 3sata and 1st GPU.

im having same problems as everyone else. no signal. CPU and GPU fans running.

Ive tried bridging the FP1 pwr pins for first boot.

I don't have SSD drive installed yet.

plan was to install windows from usb so i can use the rig to perform bios mod on GPUs first before switching to smos.

I have no video signal from board or GPU.

am i correct in assuming that i don't need harddrive installed to access bios or get video signal at least.

no signal no beeps just fans spinning.

Is the monitor plugged into the GPU? If it is, that's your problem.

I'd just first boot without any GPUs plugged in and get your OS setup.  Then you can add GPUs.

whats the ram DDR4?  DDR3?  cause it needs to be 1.2v spec if DDR4 a lot of DDR4 sodimms aren't 1.2v.....  This is key to the DDR4 version of the ONDA boards.

My suggestion;  power the board power, as well as cpu power cables.  populate the first PCIE/SATA power plug (it feeds the important stuff as well as the first 16x slot).  It is better to populate them all, but the one closest to the CPU is the one that powers the 16x slot and major system components in that area.

flip on psu power;  it should boot on its own right off.   if not; flip power on psu off and wait for it to fully discharge (everything off).  now press the cmos reset button near the USB ports.    press it for 3-5 sec just to be on the safe side.

then power the PSU back on and see if it still does the same thing.  it should boot no issues with a good cpu/ram config.


My guess it the memory;  with the PCIE slots unpopulated and only the HDMI on board hooked up;  it should POST....    If not;  memory or CPU is the culprit....  possibly the board;  but from what I have heard thus far;  the DOA rate is quite low considering how many boards overall they have made thus far.

ram i have is  https://www.skhynix.com/products.view.do?vseq=2066&cseq=75 (https://www.skhynix.com/products.view.do?vseq=2066&cseq=75), and https://www.micron.com/parts/modules/ddr4-sdram/mta4atf51264hz-2g3?pc=%7BE1D8F1A9-3DFC-4BD2-8A1E-C26ED261EB0A%7D (https://www.micron.com/parts/modules/ddr4-sdram/mta4atf51264hz-2g3?pc=%7BE1D8F1A9-3DFC-4BD2-8A1E-C26ED261EB0A%7D) i tried both.

Ill remove the 1st gpu and try the cmos reset tomorrow.

Thanks for the advice.

ONDA B250-D8P ver 2.0 (https://www.alibaba.com/product-detail/mining-motherboard-8-gpu-cards-cpu_60728152496.html)
or
Onda 3865 D8P (https://www.alibaba.com/product-detail/Onda-3865-D8P-Bitcoin-mining-equipment_60739550749.html) (the green one with celeron onboard)
?

Both appear to be decently priced (looking for one) and have decent space (56.5 mm c-c and no interfering connectors), but is there anyone having experience with the 3865 version (older/newer, any revision)?
The use of 6pin is preferred over sata/molex, if they only included the picoPSU on the board as well (as Octaminer).

Then there is a mix of the two
Zeal-All onda 8 pcie (https://www.alibaba.com/product-detail/Zeal-All-onda-8-pcie-mining_60775144865.html) ?? (all components around the PCIe slots is identical to the green one so a copy of a copy of...)

vpp; 2.5v; this is probably the issue would be my guess;  and the SPD voltage is near 2.5 as well....  thats over the 1.2v spec of the board.   maybe im approaching it wrong... but it is known these boards are picky and only take the low voltage only stuff.  *edit* maybe not... but check my post as mentioned below; I think I used 2200mhz ram.... check it to be sure i'm correct.  I believe I saved the package, so ill photo it when I get home if I can find it.

I have posted before what ram I have used myself;  see if you can try a different stick.... I got my money on that one.... if not in this thread, in phils altcoin thread.  just do a search for my username and D8P and you'll come around it at some point.  I bought mine from frys (frys.com).

Facepalm

Solved. I did not insert the ram deep enough diagonally on both boards during install.

What is the voltage of this Motherboard?

Haha, rock on!

Don't worry, it happens waaaaay more often than you'd think......

the best thing about them is that they don’t need risers and people are really talking about it.

I have been thinking to import this from the UK but I don’t know who will be interested.

Why did they dropped the previous version it was such a good thing and was fine.

These are some amazing tips and thank you. I am amused that why no one discusses this.

I think it might be because these boards slipped under the radar and not a lot of individuals got them. I find most of them in data centers.
Still they do work great.

I bought the Onda D1800 one that has 6 PCI-E slot and comes with a built in Celeron CPU.

I can confirm it works fine without any issues for several months now.  Very Satisfied with it :)

That is good to know. Which Celeron is in it? I never looked close at the CPU?

On version 1 Port 1-4 are disabled.
But the fix suggested online was....  Bios/Chipset/System Agent/Peg Port config/Peg 0:1:0 Max Link speed = Gen2

I have 12 RX570 ITX Pulse cards running but cant seem achieve ideal performance.
Max is 307mh @ 1520watts.
Anything over 26mh requires massive increase in watts.
Anything over 950core and wattage sky rockets.
anything over 1780 memory and system crashes.
0.2mh/watt is acceptable but not the low mh.
The exact same card when tested on my desktop performs @ 29.5mh with 1090core and 2000memory.

Is anyone having success at hi hash using AMD cards on the Onda board?

Is the suggested bios mod used for fixing 1st pcie slot problems (which appears to only exist with AMD Cards) hampering my performance?

Any help would be much appreciated.

Im using SMOS.
Id like to achieve 29mh per card like they're capable of.

Im missing 15% of their true performance with the onda board. Or am i chasing a rainbow?

The issue with the 1st slot is that it needs to be set to Auto like the others That seemed to fix the issue for me.
As for your performance issue it does not seem to be a mainboard issue but with the card and mining client settings. Trial and error to get the right mix is all you can really do. Is there a difference in the amount of ram between your desktop and the Onda setup?

FYI, in case you haven't seen this thread:

https://bitcointalk.org/index.php?topic=4391318.40

There was a difference initially but since changed ram and re tested.

Desktop = 16gb
Onda= 4gb

Since my last post i purchased an Asus B250 mining pro board expecting the poor performance to be a result of Onda board.

Sadly even with the Asus B250 running 16gb Crusial ballistic ram (borrowed from desk top) the results are exactly the same.

952 core 1780mem is maximum tuning achieved with 308mh @ 1530watts.

Im positive its a performance trade off when running more cards per board.

Ive since ordered a another Onda Board M06 6x GPU riserless with built in CPU.
It arrives in a few days.

FYI anyone interested in Buying my new Asus B250 and a couple new Onda B250 boards? I have 4 Onda in total but will probably keep 2 regardless.

If the riserless M06 motherboard proves successful ill be sold on max 6gpus per rig.

I saw this board showcased here: https://youtu.be/FyA07jMYCaw

Is this board reliable long-term?

Looking on AliBaba they have this https://www.alibaba.com/product-detail/4U-12-GPUs-Ethereum-Mining-Rack_60731623524.html?spm=a2700.7724838.2017115.76.1f1f4b1bwWgf66

Im really thinking of putting the the farm in a bunch of those  ;D

Thoughts?

Best board ever.  Few issues to speak of.   Awesome performance, and sturdily built.  They had their heads completely on straight by rev2.

I have one that chugs away mining XMR with older (pre 9xx series nvidia) cards.   Lots of spacing, good power distribution... What's not to like?

They are just picky on the ram modules you buy.  They really love the low voltage only (1.2v) modules on the DDR4 boards.   Someone may correct me, but I believe they swapped to DDR3 on the newer revision boards.... but I could be completely mistaken on that notion... you might wanna research that.    I own a REV1.

I bought a spotswood frame for mine, and it was worth every penny to keep myself from having to build an enclosure... and I didnt want to spend the crazy amounts for the chinese case that fits them.   I think the spotswood open frame is better.

Well, I have an issue with the GPU fans diing because of the constant torture of being ran 24/7 and the environment they are in. So, I'm looking to install all the GPUs into server cases, and will switch mobos if needed.

Can you post a link to your case?

GPU fans dying could be the case;  but if you are not running at stock settings and seeing above 72* average heatsoaked temps;  the fans will die surely no matter what.  It took me ~2-3 years to kill a set of fans on my Strix GTX980 in a cramped computer case with slightly questionable ventilation....  which for mining 24/7 since I bought it, isn't a bad run in my opinion.    The GPU deserved a new $40 set of fans before selling it for $350 =)


Spotswood thread (https://bitcointalk.org/index.php?topic=2491321.0)

Does anybody have the schematics for the hole distances and general dimensions for the ONDA B250 D8P V1.00?

Spotswood would;  check the thread above;  he may be able to help you.

I'm not about to disassemble things to measure mine......

it doesn't matter, just run it first for the future

Always hook them all up;  BUT.....


you can use the first 7 16x slots with all but the last SATA power connector populated.... as I am doing with my board (v1.0) right now.


but furthermore;
Its recommended to just power them all.
