Core Temp not reading correct VID and clock with my 2600k

Post by darkinners »

Hi, I just found the Coretemp 1.0 RC3 not reading the correct VID and clock of my current 2600k (overclock to 4.5Ghz)

I have EIST and C1E enabled, you can see in CPU-z it correctly detected the EIST speed and voltage while Coretemp always reading the MAX vid and speed.

anyway I can solve this ? I use Gigabyte P67A-UD5-B3 motherboard, Thanks

You probably need to change the power profile in Windows to Balanced.
20W power usage doesn't really indicate 1.6ghz. My 2600K idles at 1.6GHz with many apps in the background and the power reading stays around 7-9w

Thanks man, now it shows correct speed in CoreTemp but few things I want to elaborate.
1. is the VID field in CoreTemp shows the actual Vcore the CPU running ? or it's just VID?
2. after I change the power option to Balance, the clock switch between, 1.6Ghz, 2.8Ghz, 3.6Ghz, 4.5Ghz every few seconds even I am not doing anything
3. and as you can see, my CPU wattage now is much lower than before but still not as good as yours 7-9w, mine is somewhere between 10-12w
anything I need to do more to have better wattage? Thanks for your help man.

VID and vcore are not the same. Core Temp provides an estimate VID, which at times might be wrong.
Regarding your power consumption, it depends on your specific BIOS settings, and motherboard, and of course the processor itself. Not all CPUs are created equal, and some are less efficient than others at certain frequency/voltage. Voltage is also a factor, as your vcore to achieve 4.5ghz may be higher than mine, and on my motherboard a VCore offset also affects idle VCore as well. So higher vcore will translate into a higher power consumption, even when idle.

And I do get the frequency jumps you're describing as well, Windows has many tasks and processes running in the background, they could be the reason why the frequency sometimes jumps up. As it runs a long calculation or something, causing load on the CPU to raise.

Thank you so much, this explained it all :D,
By the way, I use Gigabyte P67A-UD5-B3 Motherboard, I use vcore offset as well ,with C1E and EIST enabled, C3 andC6 state disabled.
my current CPU voltages are , idle 1.6Ghz 1.032v , full loading(prime95 small FFT) 4.5Ghz 1.296v.

Thanks again, you've been a great help to ease my worry! :D
