Ryzen CPU - core voltage... differences in cpu-z HWMonitor and Open hardware monitor

[alexandruflorinescu]

Hello.

I just made a build. https://pcpartpicker.com/list/6pRJZ8
All worked nice until i started to overclock the CPU. Now I must admit that this is the first time that I am trying to overclock and I have no general idea of how things should work. I did the 3.9 GB on the Ryzen CPU and i only had the CPU-Z at the beginning but when I tried to look at the Voltages because of what i saw on the internet - they were around 2.434 V at core voltage stable. I know that i set my Voltage to be around 1.36 for the 3.9 Ghz. So i got scared and downloaded Open Hardware Monitor and CPUID HW MOnitor. The VID Voltage on HWMonitor was stuck at 1.550 all the time and the Open Hardware monitor had CPU V-core of 2.3 to 2.6 (with fluctuations). Now CPU-Z was showing t he same 2.4 At core Voltage. I ran CPU-Z stress CPU and also the FuturMark stress and cinebench. All the test got finished without crashing with a more than ok score. Now I got scared because of the big voltage and went to UEFI and the voltage was set to 1.2 V on the Core... and my setup was still on at 1.56 V. I thought it must be something that I do not see and I reset the CLR CMOS from the motherboard and looked again in the CPU-z and the other 2 programs to see this: https://ibb.co/cozckk Can anyone explain please where should i look for the cpu voltage and what is normal for a Ryzen 1700?

Thats defo not normal, and if those voltages were right you would have probably killed the CPU by now, max 24/7 voltage to use is 1.425v ever, but I wouldnt risk that, mine is doing 3.9ghz at 1.375v.

I guessing you just have incorrect readings, I use AIDA64 to monitor temps and voltages, it seems OK with my system, gives me pretty stable readings. https://www.aida64.com/downloads/NzlkMzczMmU=

Saying this it could be your bios reporting wrong voltages to your software, or the software reading the wrong sensor.

Does you bios itself have a hardware monitor that you can look at and see what that says for CPU core voltage ?

Maybe your board bundles with some sort of monitoring software of its own ? for instance my MSI motherboard comes with command centre which gives me voltage readings and temps etc ?

Based on your CPU temp, CPU vid, and Core voltage I would say yes thats right, its using power saving features enabled in the bios.

Try running the AIDA64 stress test and just quickly and see if that voltage rises, if so, then yes thats the correct reading.

The test is in tools, system stability test, click start at the bottom, and watch that CPU core volatge.........

EDIT..... CPU package at the bottom, 19.25 watts, thats nothing and needs next to no voltage whilst in an idle state which is why you may think that voltage is extremely low.
