I'm at BIOS 49, have 16GB of Crucial 1600 MHz RAM set to 1.5V in Bios.
However the IDU reports memory voltage as 0.71V, also there is a place in BIOS under real time monitoring what displays the same 0.71V for SDRAM voltage.
Anybody else has this?
Looks like a bug in Bios.
I don't think the memory can work at 0.71V and the board is rock stable so far. I also didn't have any issues updating the bios from 21 to 49, used F7 method before operating system installation.
Without being an expert i saw that too once i installed my mobo (corsair 1600 with xmp 1 checked in bios) too and mine was showing 0.72v in IDU(and still is ) i google it and probably is showing the VTT Voltage of the ram which is 1/2 of the VDD voltage cause all the others software i have including aida/cpuid/hwinfo all show either 1.5v the default or 1.440volt.
