in my x470 taichi and a ryzen 2700X since day one, thats has been the normal behavior.

My 2700X has spikes of 1.531v in one core, but usually are in 1.525.

I have everything in stock less the ram that i loaded the xmp profile, the lastest bios, and my system has a year and runs like the firts day.

Like xhue said in full load and gaming or anything other thing less in idle the system never has that insanes voltages, just around 1.2 - 1.3.

In this time i have this values.

You are welcome!

Actually, I had the exact same combo as you now. Initially, I was worried sick about the same thing. Then I did some reading and some thinking and realized it's all OK.

Voltage changes happen so fast that monitoring apps cannot keep up with the pace. By the time you see the 'scary' voltage jump, the respective core has had its voltage changed many times over.

Here is a simple test - run some CPU stress test and observe the voltage. Under full load the voltage should be around 1.2V - 1.22V. If you see something similar, you're fine. If you see 1.4V or above (sustained) while stressing the CPU, then you should start worrying. :p

I haven't heard an issue with ASRock's boards. Other manufacturers released some bad BIOS version that fried a chip or two, however.

Long story short, if you are running a more recent BIOs version with default values for CPU and voltages, you are OK.

The quick jumps to 1.4V or even 1.55V (my old Taichi did that) are safe for the CPU to handle. It's been confirmed even by AMD themselves.

I'm sorry about the formatting of the links in the first post, but "Insert hyperlink" on this forum doesn't seem to work properly for me

Hi,

I have already noticed that the voltages (VCore, SOC voltage, DRAM) set in the BIOS are often less than those reported by the various sensors.

On my X370 Taichi and Ryzen 1700X with the default/auto settings, the VCore often likes to spike up to 1.440 V (as reported by the sensors, either in the BIOS or on Windows with programs such as HW Monitor), more rarely even 1.472 V. The board seems to apply a default +1 multiplier overclock (3.5-3.9 GHz instead of 3.4-3.8)

Different sources say different things about what is safe for the VCore.

This suggests that what I'm seeing is safe : [URL=https://www.reddit.com/r/Amd/comments/6dt3qm/1700x_voltage_extremely_high_whats_normal/]1700X voltage extremely high? What's "normal"?[/URL]

On the other hand, this article has me worried : [URL=https://www.gamersnexus.net/guides/3251-raven-ridge-soc-voltage-guidelines-how-to-kill-cpu-with-safe-voltage]How to Kill Your CPU with "Safe" Voltages[/URL]

Do you manually lower your VCore?
