Question Wrong reported voltage (1.744V) for core i5 4460S ?

[mafi]

On one of my systems I run a core i5 4460S with a H81 motherboard (MSI H81M-P33).
The reported voltage is 1.744V. After running prime95 for several hours the CPU temperature didn't exceed 55 degrees Celsius with the stock cooler.

Probably shouldn't have run Prime if you were suspicious of the voltage, but yes, seems like a reporting error. 1.7 volts would pretty much lead to chip death without liquid nitrogen to cool it.

1.35 volts is about the max for Haswell.

@mafi
Try running a different monitoring program like HWiNFO for a second opinion.

CPU-Z and HWMonitor are both part of CPUID. They are likely both wrong.

Thank you !
HWiNFO shows 0.92V in full load (All 4 cores running at 3.0 Ghz with turbo boost) and 0.68V in iddle.

Then I manually overclocked the CPU to 3.4 ghz(all 4 cores running at 3.4 ghz). The voltage was auto adjusted to 1.05V. The maximum temperature in Prime95 was 65C with the stock cooler.

Not sure if that is 100% accurate but it seems close compared to the monitoring competition. The S series are low voltage CPUs.

As long as your computer is stable and temps are good, the voltage is not important.
