I believe SA is 1.2V CPU VDDQ is 1.25 And RAM Voltage is 1.5V for each of the four DIMMs separately. It's starting at CL32 6400 but not at CL30. The packaging lists RAM voltage as 1.4V, while I'm using 1.5V. Does this impact the RAM negatively?

1.5V is acceptable, but it will generate a lot of heat in the memory and you'll need a fan, particularly with a 4 DIMM setup. Still, you don't necessarily require 1.5V for stable RAM operation. I think the issue is that your system becomes more stable when VDD2 increases, which usually matches the memory voltage by default. If your CPU and board act like mine (Unify-X), aim for higher VDD2—around 1.6V is recommended for speeds over 7000MT/s to ensure proper POST. Consider lowering the DRAM voltage to 1.4V and setting VDD2 to 1.5V to test if it improves stability.
