Somehow, I update the CPU microCODE 00100FA0 from 010000BF to 010000DC.It seems must delete and insert patches files at same time open the ROM file.
And Realtek NET NIC ROM from 3.23 to 3.67.
Works fine with my X3 425 CPU and WD HD in windows 10.
BTW: This mainboard always set DDR3 voltage at V1.65, instead of standard V1.5, so the temperature of memory card is too high!
