Hello everyone :-)
I have a problem with this trifire, I cant get all the cards to be linked, one or two is allways disabled, depending on the config.
I have a Gigabyte GA-990FXA-UD5, Socket-AM3+ rev3 and 3x XFX Radeon R9 280X 3GB GDDR5
Ive connected the cards like this: They are al connected with the crossfire connection
In this config, the PCIe5 Card is disabled in CCC and cant be used. I can only crossfire 1 and 3 with x16
#Option 1
PCIe 1 - XFX x16 card primary display adapter
PCIe 2 - Empty
PCIe 3 - XFX card x16
PCIe 4 - Empty
PCIe 5 - XFX Card x8
#Option 2
PCIe 1 - XFX x8
PCIe 2 - Empty
PCIe 3 - XFX card x16 card primary display adapter
PCIe 4 - Empty
PCIe 5 - XFX Card x8
Card in 5 is still disabled and I can crossfire card in 3 and 1, but 1 runds at lower speed. (?)
#Option 3
PCIe 1 - XFX card x16
PCIe 2 - Empty
PCIe 3 - XFX card x16
PCIe 4 - Empty
PCIe 5 - XFX Card x8 card primary display adapter
In this configuration both the card in 1 and 3 is disabled. I can only use card 5 alone.
IS there something I have done wrong. I've changed the cards, so All of them has tried each other ports.
THis is getting frustrating :-/
Any smart brains out there that can help me out and point out the obvious here? :-)
