I have an Intel Pentium Dual-core E5800 CPU running at stock settings (no overclocks), but I am reading the two cores at different voltages. Core 1 appears to be at 1.39 V, while core 2 is at 1.10 V. If you look at the specifications for this CPU (http://ark.intel.com/Product.aspx?id=42802), Intel says the voltage range should be 0.8500V-1.3625V.
Does this mean my CPU is getting more power than it should be getting? Why is is that the two cores are recieving different voltages? By the way, the primary core's temperature is always higher than the second one, showing that the voltages are very likely true values.
I did nothing to my PC after installing the CPUs, I have the latest drivers and I am not overclocking. I don't see why this would be happenning!
PS: I read the voltages off of SpeedFan, and CPU-Z, both of which report the same readings. My BIOS doesn't display this information, so I can't check there.
