Riser difficulties with asrock z77 extreme6

[Kinetic915]

Anyone else having difficulty with riser cards on that board?  I have all sorts of problems, not being recognized by the bios, not being recognized by windows intermittent crashing when detected. Any suggestions?

Thanks!

I never had problems... Latest BIOS?

Good idea ill double check. It's strange because I have the same problems on two of the same board with 2 brands of risers

after doing alittle research I found the third pcie slot to be a mini-PCI according to the board specifics.  is this why I am having these issues.  I have gotten all 3 working before with 3 7950s, the specs also state the board supports "quad crossfirex".  Would running the 2 cards from the board and the 3rd from a x1 to x16 powered riser be recommended?

**EDIT  is a mini-pci a x1 slot?  It sure looks like it should support 3 x16 without difficulty.

I was able to plug the cards in there no problem.  Mini Pci and pciex1 are different, but that is a pcie x1 slot.
