CPU core voltage is low 1

[againstTheWind]

According to my Intel hardware monitor software that came with my D975XBX board my CPU core voltage is running around 1.188 when it should be running around 2.05.

I just built my first system with this board and I don't know if this is a significant problem or how to fix it.

I would greatly appreciate anyone's help.

BTW - I am running an E6400 on a D975XBX board.

Thanks!

If the CPU is working normally, then there's no need to worry. Running at a lower voltage should make it run cooler. If I were you I would make sure that it was running at full speed when you measured the voltage though. Most modern CPUs will reduce the clock speed and voltage of a CPU when it is mostly idle to conserve power and reduce heat.

I am a newbie to all of this. How do I make sure that is it running at full speed?

Ironically enough I was running hot for a while

My motherboard has a BIOS menu for the CPU and within this there's an option to disable SpeedStep. SpeedStep is Intel's technology that allows the CPU to conserve power when it's not under load. If you temporarily turn this off (then save settings & reboot) it will always run at full power so you can re-check the voltage before turning it back on again.

You'll have to search around on the net, but there are programs that will tell you what speed the CPU is running at. CPU-Z comes to mind, and I know that AMD has a program called Power Meter for their CPUs that tell you the current CPU speed, operating voltage, etc. You can watch it fluctuate as you launch applications that consume more CPU power. Supposedly modern CPUs can adapt their speed and voltage to match work load many times per second, which is pretty cool (no pun intended). I suspect that you're probably running Speedstep or something similar that is just trying to keep your CPU cool. If you disable Speedstep then it should run at full speed all of the time, but IMHO that's not advisable (mainly because it is wasteful).

I have intel d975xbx with e6600 cpu and i get error message"CPU core +2.05 out of recommended voltage. I can't get rid of the error message. It seems 2.05 comes up often for this board. How to expel error message? I just finished building this PC

I had this problem.
The recommented range in the Intel desktop utilities is wrong. The actual range is 0.850V-1.3525V, which you can find at:

You can change this in the Intel Desktop Utilities, by going to Options, then Set Sensor Thresehold.

Thank you bigrif.

I had the same issue with an Intel Core 2 Extreme X6800.
The Intel desktop utility had the cpu core voltage specs set too high.

I changed the utility's specs to match what the intel spec sheet says and now I can sleep at night.
