[SOLVED] False voltage readings?

[Unolocogringo]

While tinkering with my new build I set a core voltage of 1.28v.
Set CPU Ratio to 44.
Set memory to 3600 cas 18 and fabric to 1800 1.35v

Relevant stuff
Asus Prime X570-p
R5 3600
16 GB 3600 CAS18
FE RTX 3060TI
Gigabyte GTX 1060 6GB
1 TB 970 EVO plus
EVGA RM850x
CM HAF 912
4x 12 and 4x 140 case/desk fans.


At 4.4ghz all core load everything I check with reports 1.087-1.1v core voltage.

Are you running all 4 programs at same time ?

 

[Unolocogringo]

Normally run one at a time.
But I took a screenshot of different programs I have tried.
They all show cores @1.1v or less. but I think that is impossible @4.4ghz.

Yeas, I would expect about 1.3v+.

I'm not sure what you're looking at. In the HWInfo64, the CPU Core voltage (STI2 TFN) reading is averaging around 1.269V which is a perfectly good core voltage when under heavy all-core workload. The STI2 TFN voltage is reported out by the CPU itself in telemetry so it's pretty reliable, especially under all-core workloads.

Could you be looking at the SOC Voltage just be low it? That also (STI2 TFN) so also reported by the CPU in telemetry but it's the SOC part of the CPU. It's normal to be much lower and that range is perfect for a 3000 series CPU.

I'd ignore anything in HWMonitor as it's notoriously inaccurate for Ryzen. Ryzenmaster is OK...if you understand it's quirks. It's really only a valued tool for extreme overclockers, otherwise mostly a curiosity.

I was looking at VIN and VDD as reported in Ryzen master 1.0999 and HWinfo64 1.087-1.094 values
I tried HWmonitor and Asus AI suite also. Which all stated low voltage values for v core. At stock Ryzen master reported varying core voltages. I use it for monitoring only.In easy mode it states vcore to be 1.1v.
All tweeking is done in bios so I know it what voltages etc... I'm actually getting. But once I changed CPU voltage in bios all programs report wrong except HWinfo64.
Thanks for pointing out the correct value I should bee looking at in that program.

PS Thanks again!
