Hello, setting the pbo limit to "disabled" or "motherboard" affects how the system handles power management. The "max cpu boost clock override" command ensures the CPU can run at its maximum boost frequency, bypassing any limits that might otherwise slow things down. It also helps maintain cooler temperatures, as seen with the D15S model and a 120mm high-speed fan. Your question is helpful!
I only adjusted the curve to -20 and set the pbo limit to motherboard. It’s good that it hits 4.9ghz, but the idle temperature stays high. Previously, with D15 I kept around 50-55°C at idle—now I’d like a cooler idle and a bit more OC performance. The voltage reading of 1.487V seems normal for me.
I saw what cinebench 20 showed me and hit 90°C consistently throughout. The score jumped from 7737 to 8414 across all cores, but the temperature stayed steady at 90°C. All processors ran up to 4.4GHz, with a peak of 4.1GHz during the test—never went above 80°C. Need some guidance.
Have you attempted to upgrade the BIOS to the newest non-Beta version? AMD Ryzen 5000 series chips often run at idle temperatures higher than typical because they draw greater voltage, which generates additional warmth. The peak voltage seems a bit excessive for optimal performance.
I don't fully understand the pbo concept. I assumed lowering the CPU voltage would cause cooler temps and less power when idle and more cooling when under heavy use. However, this time it hit 90°C during testing. Before adjusting, it stayed between 50-55°C while idling and never reached 80°C during peak load. It mostly held around 76°C under heavy load.
It's typical for these premium AMD chips to run cooler when they're not in use. Since we already have your current idle temperatures, removing the side panel might not help much. These components tend to generate more heat when active, so it's unlikely to make a noticeable difference.
It's a cat-and-mouse situation. Frequency generates heat while the v-core also adds warmth. Reducing the v-core still leads to more heat production, so the scaler is attempting to outsmart the system. However, the SenseMi algorithm can't increase the chip's performance further unless it hits specific temperature limits. In this case, a new thread highlights that AMD Ryzen processors trigger a high-temperature alert at 70°C. With the default setup, the CPU fan spins at full speed (100%). This setting likely indicates a warning but most users prefer running at 80°C or higher for convenience.
