Asus b250 expert mining impossible to go beyond 8 amd cards


i use hiveos on usb drive
asus b250 expert minig
4 go ram
02 Psu
8 cards amd rx 580
when i add 9 th cards it will be not detected ?

I had two rigs with that board, now one. The one I replaced wouldn’t see over 6 cards, the other has no problem with 12. All RX 580 8gb cards.

My mining partner had nothing but issues with all 15 of his boards and swapped out for Gigabyte boards.

It’s not the OS that issue, it’s the ASUS boards, in my experience.

thanks for replay, my motherboard is Asus b250 expert mining, i hope to use more than 8 amd cards on.

we wait other replay

best regards.

Hi, only thing I can suggest is double check your bios settings. I cannot recall the exact settings. Above 4G needs to be enables. PCIe lanes set to Gen1 disable any onboard features not used. A quick google of board mining settings should fill in the blanks for anything I missed. I run this board with a mix of 12 Amd cards. 480’s, 570’s and 580’s with both 4 and 8 GBs. It’s my most stable rig atm

i have made a snap of all coonfig of my bios setting, if you can send me your @mail i will send you my config.

i am always in 8 cards.

thanks for replay

The strange thing is that you need to keep very special PCIex populating order to get the MB running for good. It is not Hive issue and it is still present for the latest BIOS update. ASUS do not give any answer for the problem. For 12 GPU you should use the next populating :

asus b250 expert minig - Работает хорошо с 12 картами.
Что бы работали все 19 нужны карты специальные (в картах свой биос он изменен)
при попытке включить 13 карту в asus b250 expert minig материнская плату не загружается просто черный экран.

в биосе asus b250 expert minig, изначально все установлено что бы работало больше 8 карт (4g, minig)
если есть проблемы с картами больше 8 . частая проблема плохой контакт райзера, или высокий разгон.


thanks for your help, so to get 12 card on this MB we should use 03 PSU ?
i will try to do this night when i come back to home

best regards.

пожалуйста, чтобы использовать 12/13 карты amd на одной и той же карте, вы используете 02 или 03 блока питания?

1= 750 вт. материнская плата + 2 карты 584
1= 2000 вт. 10 карт 584

It depends on you PSU and cards. If you have 1650+ PSU and cards tuned to consume less that 100W be Ok with just one PSU. But usually it make sense to use two PSU for more efficiency. Note that you may need additional power splitters.

No problem connecting the GPU.
I have three power supplies Chieftec GPM-1250C 1250W. Each power supply has five GPUs. The motherboard has six PCI-E slots for each power supply. With this placement there is no problem. In addition, you need 8+ GB of RAM
