Fast shipping !
bought a Gigabyte MA770-UD3 rev 1.0 + CPU AMD Phenom X4 9950 + ocz2f10664gk ( 4 gigs ) + video card. To get the memory working at full speed ( 1066 ), adjust memory timing 6,7,7, tras = 20, trc = 30.
raise dram voltage to 2.0v
Out of the box this memory only work at 800 Mhz.
I'm very happy with the increase in work load this combo can take!
