Tri-Fire Issues

THIS IS A REPOST WITH ADDED PICS. I APPARENTLY DONT HAVE THE PERMISSION TO REPLY TO MY FIRST POST.

I have been adding R9 380s to my PC when i could afford one and have recently bought a third. However I cant get it to work for love nor money. The machine recognizes all 3 and so does catalyst, however the option to enable all 3 is not there.

Benchmarks only use 2, Games only use 2. I cant get my head around it.

One person suggested they are only dual card capable but i have evidence to the contrary.

One person suggested the CPU wouldn't let it work.

Specs

MSI R9 380 4G Gaming x 3

Win 7 64 (also tried win 10)

Optoma HD131xe 1920x1080@60Hz

Crosshair V formula

FX 4300 @ 4.9Ghz

AX1200i

16gb 4 x 4g

She can see all three cards but will only use the primary and either card 2 or 3.  So much time wasted on this one its unbelievable

Re: Tri-Fire Issues

Can you try using an older Catalyst driver to see if that enables the third card? Catalyst 15.11.1 Beta available here.

Re: Tri-Fire Issues

I have tried all driver versions including yesterday's release. Fresh installs numerous times, installing cards one by one or all at once and nothing works. Any other ideas
