I have a question about crossfiring on my FM1 motherboard can someone please help?
I have a FM1 asus motherboard and i my processor is a apu 3870k and i have 8gb of ram and i just bought 2 7770s and the motherboard was cheap around 70$ and it has 2 pci-E 2.0 slots but when i pput both cards in the black one runs at x4 is it normal that when i installed all drivers it freezes when ever i go into a game and also my computer feels slower when there in crossfire.

You need at leased dual PCI-E x8 speed for proper CF/SLI operation with dual PCI-E x16 being ideal. Also there is no point in CFing on that mobo for one because of the x4 PCI-E lane and also the CPU will just bottleneck any theoretical gains you would have made even if you had a proper PCI-E x16 x16 or x8 & x8 motherboard setup.

what would you recomend that i do.
Also i tried each card in the slot and it worked fine so the cards are ok so would you say this is normal because i dont know whats going on with my crossfire setup if i upgraded to a 6100 and a board with 2 x16 slots that operate under x16 x16 would it work.

If you enjoy gaming as a hobby and spend enough time doing it then I recommend you upgrade your platform to AM3+ and get yourself an AMD FX 6300 CPU and mobo that does proper crossfire. If you have the money go Intel for sure but it is really expensive. Stay away from that FX 6100 CPU as they are no good.


ok so i shouldn't be worried this is normal that the video cards would do this in my setup.
