Can't get 5 gpus on Gigabyte 990FX-Gaming Rev1.0

[Millime]

Hi there,

I'm having troubles with my Gigabyte 990FX-Gaming Rev1.0, I'm not able to get more than 4 gpus to work on it. It was working before but now it doesnt.

I've reinstalled a fresh W10 in it, but when I connect the 5th gpu, I dont get an image anymore on the monitor.

Got any tips for that board?
Thanks!

Linux would solve your problem.

Yes, But it was working before on W10, that's what I dont understand :/

I have 990FX Gigabyte but other model, you need to put one card on the mobo or it is not recognizing the others, i have 7 ati's now with 3to1 extender.

Hi

Is it working with 4 ?

If so, try to connect your screen to the GPU that is on the first PCIE x16 port, not on x1, and especially not on the onboard graphics output.
It helps for windows to boot

Yes it's working with 4 and I'm already connected to the first x16 port

Did you checked everything in the BIOS ?

Sometimes Windows 10 does some funny things (with UEFI it can change settings in the bios), and it messed my setups before !

Bios settings are VERY basics and there's only a few.
Any ideas what i should look for ?
