Hello everyone- So I am new to AMD crossfire- here is my issue-

I have two HD 7950 cards

ASUS Sabertooth 990FX

Samsung Solid State Pro

AMD 8350

AMD Radeon Ram 16 gig


the system ran awesome- no bugs or issues. I install the other 7950 card and my system seems to hang- not fully boot inot all the programs and will not allow me to open a internet browser, Microsoft security hangs, windows sidebar will not open, and seems to just sit there. The system is not frozen, I can still naviagte around etc open windows-  I took the other card out and the system still hung- and then about 10 minutes later fully booted... WIERD.... So, I am kind of wondering if it was trying to recognize the other card and just gets hung.... NO viruses or malware are on the system.... What do you guys think?


On a journey not in cycle

Your motherbord have Expansion Slots
3 x PCIe 2.0 x16 (dual x16 or x16, x8, x8) *1
1 x PCIe 2.0 x16 (x4 mode, black)
1 x PCIe 2.0 x1
1 x PCI
Card have PCIe 3.0 may be thes is a reason.
Try gray upper slot and the third slot gray.
And dont forget the crossfire bus.

I would try installing the second card by its self and see if you have issues if not than I would be looking at the PSU.

A bad or overstressed psu can couse weird issues like this


FX 8320// Asus Sabertooth R2.0 // HIS R9 280x //8Gb of 1866Mhz ram, H50 cooling, HX850W psu all stuffed into a NZXT Phantom case.
