Biostar TB250-BTC PRO with 12 GPU

**************************************************************************************

I have succesfully installed 9 x NVIDIA GTX1060 3GB on Asus Prime Z270-A. (Windows 10 x64)
Well, I want to do it the same on Biostar TB250-BTC PRO. I have 9 x NVIDIA GTX1050 2GB.
Let's begin.

**************************************************************************************

BIOS Version: B25DFB29.BSS
BIOS Date: 2017-11-29

First of all, update BIOS to the latest one.

**************************************************************************************

-Installed Windows 10 x64 without any GPU.
-Updated Windows X64 to the latest one.
-Installed the drivers of the motherboard.
-Changed BIOS settings.

Code:

Advanced > ACPI Settings > Restore AC Power Loss > Enabled
Chipset > System Agent (SA) Configuration > Internal Graphics > Enabled
Chipset > System Agent (SA) Configuration > Primary Display > IGFX
Chipset > System Agent (SA) Configuration > Above 4G MMIO BIOS Assignment > Enabled
Boot > Fast Boot > Enabled

Code:

Chipset > Mining Mode > Above 6x VGA (EUFI OS)
Chipset > PCH-IO Configuration > Gen2 (select Gen2to all PCIE options)
Chipset > System Agent (SA) Configuration > PeX16_1 Max link speed > Gen2

-Plug only one GPU to the PEX16_1 slot.
-Installed 388.71-desktop-win10-64bit-international-whql NVIDIA drivers which is the best and tested with one GPU for days.
-Everything looks perfect. No problem so far.

**************************************************************************************

And the problems begins after other 8 GPUs. The computer starts but no keyboard no mouse pointer !
I tried to plug the GPUs one by one. When i use some slots, no mouse pointer.
When i use some slots, Windows doesnt find any GPU.
When i use some slots, Windows finds GPU.
Here is the list:

Code:

YES - PCIE16_1
YES - PEX1_1
YES - PEX1_2
YES - PEX1_3
NO - PEX1_4
NO - PEX1_5
NO - PEX1_6
NO - PEX1_7
NO - PEX1_8
NO - PEX1_9
NO - PEX1_10
YES - PEX1_11

-I have double checked the USB Riser. All of them work. No usb riser problem.
-I have tried to change Gen2 to Gen1 and Gen3 in BIOS. No difference.
-I am sure I m using UEFI Windows.

-I changed the BIOS and I see only One GPU is recognized by Windows.

Code:

Chipset > Mining Mode > 6x VGA

-So, there is no help if i choose Chipset > Mining Mode > 6x VGA
-Please dont tell me Windows 10 x64 cannot  find 9 GPU. Windows 10 x64 can find 9 GPU and no any problem with Asus Prime Z270-A motherboard.

What should I do now ? is there anyone can manage 12 GPU on Windows x64 at the same time ?

I have one Biostar TB250-BTC (x6 GPU) and i can´t put the 6th pci slot to run. No matter what i do. I am a little piss of because i have one GPU collecting dust instead of beeing profitable...

I think no more Biostar in the future...

The best mnotherboard that I use is ASROCK

You will have better luck with Linux. Windows is dogshit for mining.

I had many an issue with this board going from a 8X AMD rig to a 12X rig.

** If you want to access BIOS; be sure you are plugged into the onboard graphics.
** Double check riser USB cables; aftermarket longer ones wouldn't work.
** If you can't boot up with 1 GPU plugged into the PCIE_16x slot to install windows; install using on-board graphics, then switch to GPU after you are done changing settings in BIOS.

This is just to name a few..

I still have the issue of no workign start menu or search block even after installing all the latest OS and drivers.

I can manage 8 GPU now. But there are 4 GPU to be managed.

This motherboard is totaly disaster for me.

I am using this board with 12 x RX 580 running for 5 days without any problem . I am using the latest adrenaline driver with win10.

Hi, I saw your comment:

I would really appreciate it if you told me the steps for 12 AMD RX580 to work on this motherboard on Win10. The steps and files used, the BIOS and Windows version, PLEASE !!! And are you dual-mining eth+dcr??
THANK YOU

For Windows 10 to add 12-13 GPUs or more, just update to 1709 version. To check Windows version Run>winver and update GPU driver to latest version.

Thanks, I have tried all the GPUs one by one and they are perfect all alone at 31.5mhs. But when I put them all always ends up freezing, it's more I do not even install the drivers in the 12 GPU, just one by one, if you have WhatsApp and you do not mind giving it to me, send it to the next email and I'll talk to you. PLEASE, the DAG epoch is over me!

Thank you very much!!!!
