I have a Ryzen 5 1600AF (Zen+) and 2x 8 GB DDR4 3600 HyperX. when I select XMP1, it says 1.35V in the profile. however, when I boot Strelec WinPE USB (I’m on Fedora, I really don’t want to install windows just so I can run HWINFO), install all drivers and launch HWINFO64 it says 1.2V. so I enter BIOS again, go to Voltages and enter 1.35 manually instead of auto. no change, still reads 1.2V. the BIOS side screen shows 1.35 after reboot.
I’ve found an unresolved thread somewhere with the same problem for my board. I’m on latest BIOS.
am I missing something, is there some additional setting I need to switch so it registers? the BIOS setup is hella confusing and borderline stupid, e.g. enabling virtualization required turning on SMP (how am I supposed to guess what that is?!) that’s located in the “Frequency” subsection (wtf?!).
CPU-X doesn’t list RAM voltages. sensors lists a buncha stuff (none labeled as DDR voltage) but all at 1.2V. dmidecode also lists 1.2V for all items, but I’ve read that its data is unreliable. I’ve tried already all the listed options (and then some) and that’s why I tried WinPE, as HWINFO64 is supposed to have methods to reliably determine RAM voltage.
