Why my cpu running at 1.5v???
Why my cpu running at 1.5v???
You're curious about your CPU's behavior under stress. It seems the temperature stays high even after you checked the monitor and did a stress test, which suggests the CPU is still operating near its maximum voltage. For a Ryzen 5 3400G, the safe voltage range is typically around 1.8V to 2.4V depending on the model and BIOS settings. Make sure your BIOS is set correctly and avoid overclocking unless you're certain it's safe. Monitor temperatures closely during stress tests to ensure stability.
Vcore refers to the real voltage sent to the CPU, not VID. Choose Ryzen Master or HWiNFO for better accuracy with Ryzen systems. Ensure your BIOS and chipset drivers are up to date, and apply the Ryzen Balanced or Windows Balanced power plan.
I verified the core voltage for CPU Z during the stress test—it's 1.344. That value seems correct. Also, I updated the AMD chipset software as requested.
Voltage behavior follows typical patterns. It wasn't the first to notice the strong boost capabilities of the Ryzen desktop.
I don't own a Ryzen 3rd Gen yet, though I used to have one with a 2700x. I saw some sources saying the safe max voltage for Ryzen 3rd Gen is around 1.275V. The 1.5V you're seeing in stock settings appears only briefly and is how AMD designs it. It's considered safe, but keeping high voltage for long periods at high temperatures isn't recommended. By default, Ryzen will limit voltage when temps rise, though I think a lower setting like 1.344V would be even better. Someone else might have more insight.
3400G is Zen+, the standard used by second generation. APUs always lag behind in terms of generation. The voltage matches what it should be. He might try adjusting a slight voltage shift if he wishes, though that would mainly help with temperatures and possibly boost sustained allcore performance slightly.
