Question on Tridentz XMP voltage

[ClockIt]

I recently purchased Tridentz Model F4-3200C16D-16GTZ 3200 16-16-16-36 memory to use with a Gigabyte GA-Z170MX-Gaming 5 motherboard.

When running under the XMP profile the BIOS reports the voltage as 1.35 but in Windows the Gigabyte hardware monitor is reporting 1.38 voltage. Which is correct? I'd like to keep the voltage as low as I can while stable.

That's normal, it fluctuates based on load, but the hardware monitor should be correct.
Don't need to worry about 0.03V, as long as the system is stable it'll be fine.
