I recently upgraded to an i7-9700k, Gigabyte Aorus Z390 Ultra, and Ballistix Sport LT 32GB (2x16GB) DDR4-3200 kit. When I set the memory to XMP to get 3200 speeds or manually to 3200 in the BIOS, the VCCIO goes to about 1.25v and the VCCSA goes to about 1.3v if I leave those two voltage settings on Auto. If I set those two voltage settings to Normal, then the VCCIO stays at about .95v and and the VCCSA stays at about 1.05v, regardless of what the memory speeds are set to or XMP in the BIOS. I did do about 1hr 10 minutes of testing with Memtest86 and no errors with VCCIO and VCCSA at the Normal settings. Is the i7-9700k's IMC good enough to leave these two voltage settings on Normal for 3200 CL16 speeds or should I set them back to Auto?
