odd i got a company webserver running on the asrock nvidia 939gigalan board, the microatx one 630a/7050 chipset. got 4gb ram and a opteron cpu and the systems been running rock solid 24/7 for over 18 months now.
i guess its thanks to nvidias chipset. thing i will not bother with this 785 amd chipset board seeing as your suggesting it to be unstable.
