Please post h110 pro btc with 13 rx580 but windows 10 only recognizes me 8 graphics ... I do not know what to do ... how can I do it to recognize in windows more than 8 graphics, thanks.
You would need to get the port multiplier. Should be able to get 12 GPUs like I have.
The ASRock H110 Pro BTC+ has 13 PCI-E slots. There is no need for a PCI-E spliiter card to have 12 GPU's. Regardless, you can't have more than 8 GPU's of the same type in Windows.
I assumed you mean same type is same brand not model, right?
But can I have all 13 gpu same type in linux?
The brand doesn't matter. Theoretically you can run up to 8 AMD + 8 Nvidia GPU's under Windows 10 currently. Supposedly later this year, a driver update will remove that 8 GPU limit. Under Linux you can run 13+ cards of the same type. There are lots of videos on Youtube showing 13 AMD or Nvidia cards running under smOS or ethOS.
One issue I had with this ASRock H110 Pro BTC+ board in Windows 10 when mixing 8 AMD + 1 Nvidia card is that there are 6 PCI-E groups that are apparently shared, meaning:
PCI-E 1,1_1
PCI-E 2,2_1
PCI-E 3,3_1
PCI-E 4,4_1
PCI-E 5,5_1
PCI-E 6,6_1
For a total of 12 shared PCI-E slots and the 13th is PCI-E 7. When running 8 AMD RX 4XX/5XX cards + 1 Nvidia GTX 1080 plugged in to one of the shared PCI-E slots, I had random reboots after 10-20 minutes from driver conflicts. When I moved the Nvidia card to the PCI-E 7 slot which isn't shared, it fixed the problem. If you have a mixed AMD and Nvidia rig, I would suggest to group cards of the same type according to the PCI-E slot pairs to avoid conflicts.
Another issue is you can only manage up to 8 cards in Afterburner, so for overclocking and undervolting I use Afterburner for the 8 AMD cards and EVGA Precision for the Nvidia card.
Valuable info, this is very useful to me as I plan to have this mobo soon. BTW, how do we know which pic-e is same group? By the color of the pci-e slots?
As I mentioned, the PCI-E slots are labeled in pairs, 1,1_1; 2,2_1; 3,3_1, etc. I use the same card type (AMD or Nvidia) on each of the PCI-E slot pairs.
The black PCI-E connector slots are the primary PCI-E ports (PCI-E 1,2,3,4,5 and 6) and the white PCI-E slots are the secondary PCI-E slots (1_1,2_1,3_1,4_1,5_1,6_1 and 7_1).
