Title: Gigabyte Mboard, 2 7970, want to do 4 Post by: Spendulus on June 25, 2013, 02:40:52 AM So this rig
Is happy running 2 7970. If I add a third, the fans on the third do not run. Does not seem to matter if I
Basically the fans should be running after the POST startup, so I do not think it matters whether Windows or Linux at this point. What to do? How do I run four cards, or maybe it can't be done?

Because the fans never turn on, it seems that the computer does not recognize the card.That actually is the issue.

Its some power saving mode and the card doesn't look like its works but the computer see it. That was my case. If it put a load to the card the fan you start to spin. Since your rig does recognize the 3rd card in devices I would put the 3rd card in the 2nd card slot and see if it works. That will have you narrow down the issue

I don't think it exists in linux, but regardless, the 3rd card does not spin up before the operating system is loaded. I believe all the cards should power on when they are recognized by the motherboard POST, right?
