Well, its being a long ride for me...samsung B-DIE, trying fast preset 3200mhz. Seems like my ram does not like voltages. If setting a voltage of 1.42v it gives me error on memtest. My 1800x SOC is set to 1.05v, anything higher causes error too. Crosshair VI Extreme seems not to be a great ram overclocker, as changing VDDP voltage does not apply. My questions are: how important for solving errors is VDDP voltage? PLL affects ram oc (using 1.8v)? What other RTT values should i try to oc this kit (TeamGroup Xtreem 4000mhz 2 x 8GB)? Can a higher voltage than needed to RAM causa instabilities and errors?
