People all over the world (especially in China) please let us know when you start seeing these in supply.

Also, a lot of people have suggested the Biostar TB85 board as an alternative to the ASrock H81 boards.
Here's some Juicy tidbit of information about the TB85 - it was supposed to have an 8 PCIe slot varient as well.
Here's a screenshot from the Biostar TB85 Manual :

PS: this is from another forum where someone else spotted this.

Again, I look to our Eastern brethren to help us confirm these exist? A low cost 8 slot motherboard would be AWESOME.

in the meantime  this one is on sale


https://www.newegg.com/Product/Product.aspx?Item=N82E16813138424&cm_re=biostar_b150-_-13-138-424-_-Product


70 bucks before the code below



022BW44



35 bucks  it will do 4 cards

that allows for a small psu

you can use the g4400 cpu

https://www.newegg.com/Product/Product.aspx?Item=9SIA6KX4BD2910&cm_re=intel_g4400-_-19-117-625-_-Product

or a used g4400t less power

http://www.ebay.com/itm/Intel-Pentium-G4400T-2-90Ghz-SR2HQ-LGA-1151-Socket-X626B529-Processor-/262837490473?hash=item3d3255d329:g:WpgAAOSwUKxYjPLK



so 35 + 52 = 87 for four cards

That Motherboard will only do 3 Phil it has only 3 physical slots... I love the GT7 Z170 boards though, have a couple of those, bought em off of your recommendation a long time ago :)

can't find this anywhere, even rarer than the h81 pro btc, i don't see the point...

Deadsix...

Did you get 5 cards working on the GT7 Z170 ?

I just ordered this Biostar TB250-BTC from my local supplier.  Supplier says it will arrive this Friday.  I'm near China, but not in China.
Hopefully it would work with 6 GPUs.

Thank you for sharing that, keep us posted. Also share what price you get it at.


No, sadly, im still waiting on other people to confirm if it is indeed possible, I have been running my two boards with 4 cards each riser free just like Phil.
I do however remember someone sharing that they got 7 cards working on the MSI Z170 Krait3X. Here is the thread :

If you are in Hong Kong, can you let me know where you ordered it from? Would like to grab one too, if the price is right.

I just received the Biostar TB250-BTC board + Intel G4560.   Installed 6 RX470 GPU on it, and it works fine!
It's about 10-15W lower than the Asrock H81 Pro BTC + Intel G1840 I swapped out.

It's about USD 83 here.

That's great news man, now I wish Biostar will start shipping it outside China.
Btw, if you ordered it online, could you please share a link?

I would also like to see this show up on sites in north america to order, now that tb85 sold out on newegg i need a new one to get. ill just send them an email to see market availability i guess..

this is card is very hard to find in any of the e-tailer sites also..damn...too much people wants it ...

United States will start to see them the week of April 21st is the info I have from biostar and I can get them in bulk.

Where to buy it in large quantity in Europe? Any tips on reliable European Biostar distributor?

Where did you order it please? I'm in Japan and wouldn't mind shipping cost from nearby China...

I just spoke to the supplier (located in Hong Kong) in person, he's open to accept orders from overseas.
You may contact him via his facebook page:

https://www.facebook.com/junmaxhk/

i heart that user needs to also configure his/her software(operating system&drivers) for using more than 4+ card at windows 10.
is that right ?

Not on these mining boards, these are pretty much plug and play.

Biostar has official instructions for this board specifically: http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

might be a crazy question, the M.2 ssd slot. would that affect 6 gpu setup? I want to know if it works fine on this board but also any other one. M.2 vs SSD for mining, which is better. i was thinking less cables more air flow.. thanks

Hey guys,

We recently bought 40 of these on newegg.ca, we were at first so happy about that purchase since it has 2 molex and 6 PCI-e.

We are still testing them, but so far we can only have 4 GPUs connections even if we tried this:
http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

I looked, there is a bios update dated on March 30, we will see if it helps.

So far, we will have to send them back if the problem is not fixed.

Keep you guys posted

Hmm, I thought there were a few members on these forums that had reported running them with 6 GPUs? Hopefully one of them will see this thread and respond...

 :) that's why it's out of stock since the beginning on newegg.ca :)

You can try to PM some people talked about this before, who said it's just plug and play, nothing else you need to do. Better to get detailed info about the rig parts. In another thread earlier today, it's reported only skylake but not kabylake supports 7 GPUs on MSI z170M5 board.

I am running 5/6 gpu on these motherboards.  I have not updated to the beta bios.  I had the problem of only 4x GPU's until applying those changes.  I am running Win10 x64.

Im not on facebook anymore, anyway your supplier could do the TB85 bulk orders?  I have been working on trying to get the Sales manager online to see if I can do a custom bulk order of the TB85, still waiting to hear back

I have this mb and works well with 6gpu. Tried amd rx470 and nvidia 1060/1070.
Win10 64 and change settings in bios: Miner Mode Enable and Max Tolud 3.5
I never plug power on mb.

I will miss tb85. Do the same job and cost less

I have since bought more of this Biostar TB250-BTC board, and paired it with Intel G3930 CPU, and a M.2 64G SSD, DDR4-2400 4G RAM.
I have 10+ rigs of this setup running with 6x RX 470.....stable for weeks.   

It's my favourite setup thus far because of the M.2 slot for SSD, I don't even need to use any SATA data or power cables in the whole rig.

that card is good. i have one ordered from junhmax at honkkong paid much in taxes and shipping. but it's worth.

you don't power risers?

I need 6 of these board and I'm waiting on newegg.ca to get them back in Stock, you jerk ordering 40.... I hope they have an eta.. or if there is another place selling them at the same price that would be awesome!

for clarity >>> I don't even need to use any SATA data or [[SATA]] power cables in the whole rig.

yes i use powered risers.

I am having the same problem with the Mainboard. I think it might be a driver issue though. I can only use the newest driver, since I am using RX 580s.

@carloshell
Did you try earlier drivers (16.9.2). I think the Mainboards should work with them.

Deepinthemines is supposed to have them in stock sometime in May, but I believe they are charging $155 each. I am fairly sure that they will sell out even with that markup in price. :/

I had 5x GPU working with 16.12.2

I have been updating rigs and am running into problems with 17.2.1 -- only 4 GPU's work.  I will try the latest beta bios and see if anything changes.

Edit: No go.  I am trying the latest bios with 16.12.2 again.

Edit2:  With 16.12.2 all my GPU's are functional again.  I will try to let Biostar know.  17.2.1 works fine on all my H81 rigs.

Edit3:  I just realized it does say to use 16.9.2 in the special instructions.  I can confirm 16.12.1 and 16.12.2 work fine.  Beyond those version who knows.

can any one post some url's for pcie usb risers for this mobo..i would really love to get some ...

I have used these ones so far. They accept credit card, PayPal, BTC, Eth, Dash and probably some other coins that I can't think of right now.

http://www.parallelminer.com/product/ithoo-usb3-0-pci-express-1x-to-16x-extender-riser-card-adapter-w-24-cable/

We fixed the issue, it was motherboard related.

1) Update the bios
http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=865#download


2) Follow this guide from biostar:
http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

Super stable and mining for a week now.

Cheers!

What driver are you using?  Like I mentioned above... 16.12.2 I'm good but beyond that I have issues.

I ordered 2 of these boards; 1 to replace a MSI Z170A pro carbon that would not run 2 cards for the life of me. I installed this one, enabled mining, ran DDU to remove the old drivers and installed 16.12.2 and rebooted and all 6 cards came up and mined without issue:)

Hi all,
I have a TB250 with G3930 CPU and was able to run with 4 GPU. If I add the 5th card, the rig will not boot up. Also I have a 1200W power supply and updated BIOS to: B25CF330.BSS and AMD Drivers 17.5.1

Also followed the same instructions at: http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

Any guys have the same problem?

I just got a couple of these boards and they have a newer June release of the BIOS and I can only get 4 GPUs working.  I get the 3 of 6 with yellow '!' icons per the Biostar instructions so I'm obviously missing something.  Can someone who has gotten it to work please re-translate the Biostar instructions ::), the translated english is not clear.  Specifically these: http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=768

Here's how I'm reading it:
1) Use default BIOS settings except just turn on mining mode.  (somebody mentioned "set Max Tolud 3.5" too?) but that's the only setting change from defaults I'm seeing.
2) Windows 10 auto installs a base driver for Nvidia, so I'm guessing that I (right-click and) uninstall the (default) driver from device manager to get to the "Microsoft Basic Display Adapter".  I have the latest nvidia package installed so I'll need to do a cleaner install.
3) Once this is done then I reinstall the (specific AMD) video card drivers, reboot and everything should come up.  Problem is I'm using NV cards so I'm just using the latest.

I've tried both Ubuntu and Windows 10 and can't get more than 4 cards recognized stable with this board. :\  I'm sure it's pilot error, hopefully it's something simple. Thanks!

1500W PSU // 6x NV1070

Hi Friends

i am totally new to the Mininig community and Just started by setting up 6 GPU Nvidia Ge force GTX 1060 using Bio star TB 250 BTC Mother board and 64 GB  hard disk Liteon.

My problem is that
1) i am getting only 2.5 MH/s where as it should be 19 MH/s per card
2) only 4 cards are running ( tried to create virtual memory also but that did not work.

can any one help pl.


regds

Hello. I just got this motherboard but i have the same issue as many people. I got 5 gpus but only shows 4.

I read some information over website and it said update the bios and change the option "enable 4g decoding"

Where is this option for this motherboard... i navigated all over the bios with no luck... please help me... or if it is other solution for me to get the 5 working

I am a reseller of Biostar products in Europe.

For those that can't see more than 4 or sometimes even less, from my experience, if you have risers with SATA power, make sure that you use only two per cable. If you are out of SATAs' use molex adapter to SATA power.

I could see all the 6 GPUs on a TB250 mobo but had unstable performance, so I did what I mentioned above and it worked perfectly. All i did in BIOS is turned the mining mode on and nothing else. This rig was with 6 x 1060s'.

Should you need any help, feel free to contact me and I help from what I've learned so far :)

You should try some software like 6gpu_mod. I think it should work also on 5 pci-e motherboards. In the past I got this issue on motherboards  with 6 pci-e slots.

Thanks for your answer. That is the way i have them connected. Two cards in one data power and one alone


Also thank you for your replay. But this motherboard is supposed to support 6 gpus and specially for mining!!!. I am new to this so i don't know about this software... i will research

I'm also setting up a rig for a client and there's an issue with unstable mh/s. This might be a riser or power issue. Still identifying the cause of this. Will get back to with the solution here.

As I've said , I got the same problem in the past,
 
"But this motherboard is supposed to support 6 gpus and specially for mining!!!"

 -the motherboard was AsRock H81 Pro BTC so it doesn't matter.

I have 10 of these in my farm

reliable
cheap



Only complaints are

2 of the boards, one of pcie lanes broken
2 of the boards died
1 board acts weird -- inconsitent hash had to throw it out




I got 7 GPUs to work on some of the mobos, not others

anyone know why?
