Anyone have some experience with ASRock B250M Pro 4?
I'm having problems getting the 4th and 5th card getting detected. Also, when i link the first m.2-pcie riser i lose one of the pcie cards. Seems like a bios config problem but i can't find the reason.
edit:
got the 4th card working with a m.2 to pcie adapter plus riser.
everything gen1, audio disabled and only 1 dumb plug on the card which doesn't have riser.
going to try the 5th on the other m.2 slot.
edit2:
for no reason everything got unstable after 12 hours with 4 cards. One of the GPUs (the one linked to the m.2 slot) is very unstable and hangs the process. I'm using a Corsair 750W PSU, 280W on the plug, 4xRX460 4Gb. VM 16384MB. Bios updated, win 10 pro.
edit3:
just notice that one of my cards is drawing power on a bigger gap than the others. GPU0,1,3 drawing 55W each. GPU2 drawing from 40W to 70W. (doesn't show on HWMonitor, only on GPUZ.
Any tips?
Tried different cards on each riser. Everything works well with 3 cards. When i get the 4th one of them gets the power drawing variable and after a while the system crashes.
edit:
Solved. PSU 750W working with 5 cards, win10, 3pcie slots plus 2 m.2 adapters.
Do you mind letting me know what settings in the bios you had to use to get 5 cards running?
I have the same board. going to be running ubuntu, with the riser setup - 2 m.2 to pcie adapters, and then 5 risers (3 to the regular pcie and 2 to the m.2 adapters)
ill be using 1060's
is it just set 4g decoding to ON and then the upper memory lower (tulad? w.e that is) to 1gb?
