P8P67 PRO x8/x8 Crossfire + PCIe x1, all at the same time?

post #1 of 3
Thread Starter 
I read that when using the P8P67 (NON-Pro model), once the second PCIe x16 slot is enabled to x4 (default x1) both PCIe x1's and USB3 three and four (front panel USB3) will be disabled.

Will the P8P67 Pro allow me to use two of the PCI Express x16 slots for CrossFireX in an x8/x8 configuration as well as one of the PCI-E x1 slots and one PCI slot all at the same time? Since the P8P67 Pro board uses the Asmedia ASM 1440 chip, I can do x8/x8 CrossFire and PCI-E x1 all at the same time?

if the last slot is connected to the PCH then yes, you can only have 16x lanes from the CPU, but the PCH has 8 PCI-E 1x lanes, and they are used for things like audio, lan, extra sata, and pci-e 1x slots.
