The voltage levels for the Ryzen 5 3600 are excessively high.
I have my new PC running with a Ryzen 5 3600, and the voltages are consistently at 1,375v with fluctuations! That’s really high and concerning, especially since temperatures remain between 40-60°C even during light usage. How can I stabilize it? I’ve tried power plans and undervolting to 1V in Ryzen Master, but my PC just shut down. I read on Reddit that AMD says voltages between 0.200V and 1.500V are normal for the CPU, and temperatures naturally swing around 10°C when boost is active or inactive. These are expected behaviors, so it’s not unusual. However, my system stays at 1,375v without variation, which feels risky and could shorten the CPU’s lifespan by overheating during idle or light loads. If I have to adjust settings in BIOS, I need clear instructions—I’m using an MSI MPG X570 GAMING PLUS AM4 motherboard. Also, the maximum load on Cinebench 20 reaches up to 87°C. I’ve been browsing forums all day but haven’t gotten any responses; most views are in the hundreds. Someone please help me out ;/
What tool are you using to monitor core voltage? You should check HWInfo64 and CPU Core Voltage (SVI2 TFN). What kind of motherboard do you have? Please share your full system specifications. Have you adjusted the core voltage or CPU multiplier in BIOS? Temperatures tend to change a lot under light loads, thanks to the 7nm process and the boosting algorithm. It’s best to set a custom fan profile that stays steady around 65-70°C, with a quiet speed until it gets warmer, then becomes noticeable at around 85°C. Only when it reaches 90-95°C should it get very loud.
HWINFO64 and Ryzen master are set up automatically. I've only disabled PBO and enabled AMD Cool Quiet, achieving a minimal impact.
SVI2 TFN is currently fluctuating between 1,300 and 1,450 while using steam, hwinfo64, and steam open.
I've adjusted the aggressive custom fan curves on the BIOS with little impact on temperatures since they're mainly due to voltage levels my CPU doesn't require. Would you consider skipping Ryzen Master entirely and keeping everything in BIOS auto except PBO off and AMD Cool Quiet on? Many people say that maintaining a constant 1.3+V can harm a PC over time, which is why I'm concerned. AMD suggests the voltage should stay between 0.2 and 1.5 but not hover at 1.35-1.45 all the time.
The issue is with Steam, which is well recognized. It doesn't behave nicely with CPU's, always performing actions that prevent it from entering deep sleep in C6. This app is quite bad; don't allow it to launch at startup and terminate immediately after playing the game.
ADDED:
Additional configurations in BIOS are necessary...
Turn on Advanced C States
Activate Cool n Quiet
Activate CPPC
Set CPPC Preferred Cores
Avoid leaving in AUTO or DEFAULT settings, as many BIOS systems treat this as disabled.
Make sure to download the AMD Chipset drivers from the official AMD website.
After installation, ensure the Ryzen Balanced power plan is activated.
RyzenMaster works, but it's not the recommended tool for monitoring. HWInfo is the best option. You're correct that voltage should decrease, though you might never notice it dropping to 200mV. It only reaches that level during C6 deep sleep, and no utility can accurately report voltage without waking the processor, which then reads an incorrect value. Usually I see around 600mV, which is the last measurable state before entering C6.
Hello everyone,
I just wanted to share my experience: I have a Ryzen 5 3600. Initially, I overclocked it to 4.2 GHz using voltages between 1.375 and 1.4V. However, at 1.35 GHz it became unstable, and the temperatures were high even when the PC was idle—around 55 to 60 degrees Celsius. At first, I thought it would work fine, but then I faced problems: for two consecutive days my computer froze completely, the screen appeared frozen, and it restarted automatically. I checked the BIOS and saw that the XMP profile was active. I tried lowering the CPU speed to 4GHz and set the voltages to "auto," trusting the motherboard to manage it.
Later, I noticed something unusual. Using the "CPUID HWMonitor," the voltage stayed at 1.100V (as configured by the motherboard), and the 4GHz performance was stable. Idle temperatures were between 38 and 45°C—much better than the 55-60°C I experienced before. (It’s currently summer in Spain, with ambient temps around 25 to 30°C.)
But there was another observation: when I stressed the CPU in several programs (CINEBENCH, HeavenBench, and a heavy workload for 5 minutes), the voltage dropped slightly to 1.075V, yet it remained stable. The maximum temperature during that stress period was 66°C.
In summary: running at 4GHz with 1.075V for five minutes under load kept the system stable, with temperatures only reaching 66°C.
I’m not sure if this is normal, but I thought it might be okay.
