I'm using the latest ''official'' one: 0901.

Everything is working fine, except Windows update messing my Win 7 install by installing ''ACS-6xxx'' drivers, confusing the NEC USB3 and Marvell SATA6 drivers with those. It was a mess. 2 hours of black screen of death, until reading somewhere how to get rid of it.

Now everything is fine. Just be careful when installing Windows Update. Be sure to NOT install, and also ''hide'', any ACS-6xxx updates or drivers. There is NO ACS-6xxx component on our board. Windows update is confused.
