LSI controllers are compatible with most motherboards. As long as the motherboard has a compliant PCIe 2.0 slot (or 1.0 as it is backwards compatible) you will be fine. I am running two of the 8i controllers on a ga-890fx board with no issue.
I just got an HP LTO Tape drive with an LSI SAS9220-8i and have an 890fxa-ud5 mobo (is that what you meant by ga-890fx?) and the mobo refuses to load Windows if that card is installed, I get this error:
"No physical memory is obtainable at the location necessary to load the Windows Boot Manager"
What is the exact model of your LSI card and mobo?
I've already listed my LSI card on eBay and bought a HighPoint card as it seems these 2 cards simply aren't compatible so I'm assuming you have a different model of either the card or mobo.
