ASUS Z370E Manual Voltage and LLC Settings not working

Mercayyy
Level 7
Hi all,

I seem to be unable to set a manual voltage on my Z370E as any voltage I set ends up with stock voltage being applied. (I.E Setting 1.35V in UEFI results in 1.002V fed to the CPU as seen in both the UEFI and Windows monitoring tools, which forces me to baseclocks and x37 multiplier while using manual voltage just to boot into Windows)

Currently, I am using adaptive voltage which works very weirdly as LLC settings do not seem to work. I have set 1.35V and x49 multi in UEFI and get down to 1.264V under stress tests, even with LLC at Level 7. I have set IA AC & DC values to 0.01 and SVID Behaviour to Best-case Scenario.

I am rather confused by this as I have replaced the motherboard and the CPU to see the same issues. Can anyone help me with this?

I have the exact same issue, but with a prime-a z370. What is going on?????

Both unable to set manual voltage, and LLC not functioning with adaptive voltage

I use the 6015 newest edition bios

Having identical issues with my Prime Z370-A on 0615. Whenever I use manual voltage it just defaults to using the Intel programmed in SVID settings. If I disable SVID then it just sits at 1.1v, which obviously doesn't work for overclocking. Adaptive works, but the actual set voltage doesn't correspond to what I've set in the BIOS. I can get it to change, but I have to keep trying different settings that give me no where near what it's actually set to.

I've tried different combinations of basically every option available in the BIOS, as well as almost every BIOS version that's been released. I've got AC/DC load on 0.001 right now, and with it set to default adaptive completely refuses to do anything but follow the default SVID settings. I'm running at 1.35v with LLC7 on, and I get vdrooping down to about 1.26v on Prime95 small FFT tests. The actual settings in the BIOS are something like 1.3v with an negative 0.5 offset, which somehow lands me at 1.35v. If I change the offset up or down by say 0.01v I'll see completely random changes that don't correspond to what I've actually changed.

Same problem with the "ROG STRIX Z370-F GAMING". Changes to the VCore have no effect on the actual value.

It looks like the latest BIOS versions, 0616 has fixed the issues we've been having. The thread I'm about to link has a bunch of other people reporting the exact same issues that have been remedied by this latest release.

I'm guessing some of the different revisions of the boards weren't working 100% with the previous BIOS versions and that difference has now been accounted for.
