1.45 volts with a 3400g weight?
1.45 volts with a 3400g weight?
Hello! I recently assembled my first PC (R5 3400G, initially using an iGPU) and was experimenting with overclocking. I noticed it's running at 1.45 at stock speed during load, which isn’t ideal even for casual use. I found this info in a Ryzen Master guide, but when I tried adjusting the voltage offset in BIOS, it didn’t respond well. That led me to wonder if the actual voltage was lower than expected—AIDA64 showed around 1.26–1.32V under load. This raises doubts about the reliability of the data I received. Who can I trust? Any recommendations on software or methods to verify this? Thanks!
1.45 is the setting for single core turbo. It won't last long and that's expected. No need to be concerned.
AMD Master continued monitoring throughout the entire stress test, not just briefly. At least that’s what they’re stating. I’m leaning toward trusting aida64 since it shows typical voltages, but I still want another perspective because I’m aiming for a CPU voltage around 1.3 and keeping SOC voltage under 1.2.
What kind of stress test were you executing? Was it single or multi-threaded? Have you upgraded the BIOS to the newest release? Are you using the most recent Chipset driver from amd.com? Did you switch the power plan to Ryzen Balanced in the Control Panel under Power settings? Remember, even though it’s labeled 3400G, the 3000 series isn’t Zen 2—it’s built with 12nm FinFET technology, making it a Zen+ CPU. A quick Google check suggests up to 1.375V is safe during idle. It’s possible Ryzen Master displays VID instead of VCore (the reason isn’t clear), but since I can’t test a Zen+ CPU, I can’t compare. When you installed Ryzen Master, did you download the latest version? I’m adjusting my expectations because I have a different setup. You’re not facing any issues since your CPU isn’t reaching its power or thermal thresholds. It isn’t throttling because of overcurrent or overheating, so it’s not dangerously overvolted. You also haven’t changed PBO settings; it raises power and temperature limits to push the CPU beyond its normal speed.
I haven't altered the pbo file, and for a stress test I used cinebench r20 with multithreaded execution.
Regarding BIOS, chipset drivers, and power settings, there are several discussions on Reddit where users with 3400G systems mention the CPU was drawing too much voltage until they activated the Ryzen Balanced power profile. For safety, it's recommended to install the most recent chipset driver first, then update the BIOS. After flashing the BIOS, access the Control Panel (remember CP is required) and navigate to Windows 10 settings—power plans aren<|pad|> can’t be changed there. Once there, select the Ryzen Balanced plan and click Apply.
