uninstall the driver, put in the first card and install the newest driver reboot, then put the other card in and then screen will blink couple times as it pulls the driver for the second card. after the blinking stops i always reboot again and it should be displayed under the gaming tab in the software.
aaaaah this is the metod? when i instaled the 2º graphic card i only put the card in the slot and don't touch nothing
ok i do it all pas.
1º unisntall drivers from the device manager
2º Turn off the pc and take hte 2º graphic card of slot
3º on pc and install in the 1º the new driver 17.11.4
4º turn off the pc and put the 2º graphic card
5º on pc, the system windows reconoigse the graphic but when i open the crimson softwere, not appear the crossfire option in "gaming (global configuration) "
I have done this procedure several times, inclusive uninstall drivers fo the 2 cards toguether and install toguether the drivers.
i change of slot position the graphic too.
I have trie all configurations posible and this crossfire system never appear to enable.
in GPU Z all time "CROSSFIRE DISABBLE."
i don't know how to do it...
What PCI-E lanes on the Motherboard are you using? One of the lanes is running at PCI-E 3 x2, CrossFire requires 2x x8 PCI-E lanes to function.
My motherboard only have 2 PCI-E to GPU, in other slots i can't put gpu cause this slots are diference of the GPU connector.
in the specs of my motherboard appear:
- 2 x PCIe 3.0 x16 *
- 2 x PCIe 3.0 x1 slots
- 3 slots PCI x * slots PCI_E4 sólo correr PCIe 3.0 x1 velocidad cuando el PCI_E1 o ranura PCI_E3 is instaled 1 gadget.
i think that i have insuficient PCI-E lines of the processor.
i have conect in the motherboard: 1 M.2 1 SOUND BLASTER CARD, and 2 GPU.
That'll be the reason it's not working then.
OMG i quit sound blaster card and crossfire is "INABLE" jajajajaj, but now i have a new problem
i have a 5.1 system sound but my motherboard only accept 7.1... it dosn't work my sound system ;(
aammm waths happen with the performance of crossfire, in afterburner my 1º gpu rx 580 only works on 16%
my 2º gpu rx 480 works on 100%.
i disabled ULPS to msi afterburner, but i have more performance when i disable crossfire and play with 1 card.
One of your PCI-E lanes is running slowly, so CrossFire performance will be bad as its running below the minimum required x8 speed.
i will sold my rx 480 who want it?
You can sell it elsewhere, this is not Ebay.
Nah it's a joke i am happy whit my crossfire but now i will have to choose in diference moments, use the cross or use the sound card.
THANK YOU FOR HELP ME GUYS TO SOLVE MY PROBLEM, AND NICE TO MEET YOU
