Your RAM is displaying various voltage readings.
Your RAM is displaying various voltage readings.
I adjusted the voltage setting in the BIOS to 1.35, but it seems your CPU Z is reporting that two of your RAM modules are operating at 1.25 volts instead.
CPU-Z interprets XMP profiles from the SPD rather than measuring RAM voltage directly. The system supports a 1.25V rating, while another version works with 1.35V. To verify your actual RAM voltage, install HWInfo64 and look for PMIC voltages within it.
Frequently the BIOS defines voltages that aren't accurate, like showing 1.395 when it should be 1.395 or even 1.385. A 0.1V difference can feel quite noticeable.
