overkill with 1.39V cpu and 1.43V ddr4, note: my z590m motherboard with the same memory sticks:ddr4 voltage set to 1.41V would only work for about 2 seconds and then shutdown from the memory ram voltage too high. 1.34V to 1.39V they would work fine, were memory trained by typing 1.35V in bios. same amount of memory 4gb sticks x4 as my previous ddr3 setup had. maybe i will wait till the ddr6 come out with 4gb stick size or maybe ddr7, i cannot wait for those 4gb memory sticks.
