This is your board, Am I right?
https://www.alatortsev.com/content/images/2018/02/IMG_5347-1.JPGI've checked your reference image, question is: did you installed the cards just like in the image (
same PCI-e Slots)?
If so, try to move them one slot above where they sit (
PCIe-1,3 & 5 instead of 2, 4 and 6) to check if you got a
bad PCI-e slot.
Alternatively, just try all the slots using a single GPU and see if it can be detected.
That is indeed my board.
I tried these combinations:
- 1, 3 and 5 - one card won't work
- 2, 4 and 6 - one card won't work
- 2, 5 and 6 - works but high temperatures
- 4, 5 and 6 - works but high temperatures
I will try putting a single card in each slot to see if there is an issue, but that doesn't seem to be the case because 2, 5 and 6 work and 4, 5 and 6 work, just with high temperatures. Could it be some BIOS setting I'm missing?
