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?!).
I’m mainly checking if there’s something else to switch in BIOS or that’s all there is to it and my setup is just incompatible; I’m waiting to snag a used 5600 when they drop a bit more in price, since they’re supposed to work better with faster RAM. but sure, if you get around to it I’d appreciate any config you can share.
Here’s my sensors config: https://github.com/frankcrawford/it87/pull/12/files
So I believe the motherboard is running my ram at the correct voltage, just the dmi is hard coded.
my original reply vanished, so here I go again: thank you very much for your efforts and for following up. I couldn’t get the driver to compile on my system but that wasn’t my primary goal, guess my setup is just incompatible. hopefully I’ll get a used 5600 by year’s end and check then. thanks again.
No worries!
I believe for the driver you need to install
build-essential@development-tools(forgot about fedora) and then runsudo make dkms.
