Hey,
Lately I’ve been optimizing my PC across different areas — GPU, CPU, and RAM. So far I’ve achieved rather satisfying results: no temperature issues and no signs of instability. Because of that, I doubt I’ve broken anything with my settings, or that they are excessive or unsafe for
daily use — quite the opposite, actually.
That said, I wanted to ask whether this behavior is a bug, something normal for SoC on AM5, or something to be concerned about. I’ve noticed that SoC voltage can sometimes show a strange spike above the configured offset. It’s hard to trigger during normal usage (and I’m not even sure whether it happens at all outside of specific cases), but I’ve observed that it usually appears right after launching ZenTimings. Yesterday, with SoC set to 1.185V, it briefly jumped to 1.241V. Today I wasn’t able to reproduce a spike that large, but it still happens to some extent.
I also have a question regarding a BIOS option called SoC Uncore / OC Mode. From what I’ve read, when using offset mode it’s supposed to prevent voltage spikes above the configured limit and is recommended to be left enabled. Personally, I don’t fully trust options that have “SoC” and “OC” next to each other 😅 — however, regardless of whether this option is enabled or disabled, the SoC voltage spike still occurs. I’m not sure whether ZenTimings has anything to do with it, but based on my observations, HWiNFO seems to report these spikes most often (if not exclusively) when ZenTimings is running.
I’d appreciate any insights regarding this behavior or that BIOS option in particular. I’d really prefer not to end up joining the group of ASRock users with a cooked CPU…
System details:
Motherboard: ASRock B650 Steel Legend WiFi
CPU: Ryzen 7 9800X3D
GPU: RTX 4090 MSI Suprim X
RAM: G.Skill Trident Z5 6400Mhz 32CL
I’m also attaching screenshots/photos of benchmarks and CPU, GPU, RAM and SoC BIOS settings, in case they’re helpful.
Thanks in advance for any feedback.
