Vcore and Core VID

whiterabbit · 7 Jan 2017 at 13:25

Hello

I am running my CPU with Vcore set to 1.170v in the BIOS. According to HWiNFO64 this results in a Vcore range of 1.092v to 1.164v.

I also note that HWiNFO64 provides Core VID readings. Am i correct in interpreting this as the voltage each core is requesting, and that the Vcore reading is what is being delivered?

Thanks

Henry

I think this thread (see link) confirms that my prognosis is correct.

If anyone can add their own thoughts it would be greatly appreciated.

Your description is what I believe is true

People use them interchangeably. It doesn't help that CPUz shows vid, but calls it vcore.

The difference is small (20mv on my 4790k) so I wouldn't put too much thought into it.

The difference is substantial on my 7700K monitoring in HWiNFO64. vcore has been manually set in BIOS at 1.170 which gives a maximum reading in HWiNFO64 of 1.164v. The VID on the other hard tops out in HWiNFO64 at 1.412v.

However, if the vcore is actually what is being supplied and the VID is just what the CPU is requesting, not what it is receiving, then there is no problem here.

I would suggest that the Vid reading form hwinfo64 is false. Quite often it gets confused and lists the wrong voltages for things, especially on brand new hardware.

In which case I am very happy that my system is stable with my current vcore settings. Looks like I have a reasonably good chip
