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.
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
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
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
