[SOLVED] VCORE, CORE VID 0, 1, 2, 3 problem?!

The processor in the bios is set to 1.46 V for 4.5GHz, stable at PRIME 95, small ftt, temperature up to 77C. Now, at idle, the HViNFO64 shows a VCore of 1.428V and full operation of 1.356V and again of 1.428V on the iddle.
Core VID 0, 1, 2, 3 on iddle shows 1.361V, and at full operation 1.386V.
Is this within normal limits? Is there a risk of degradation? What voltage should follow?

Old overclock.net experts recommend 1.45 volts as a maximum for Ivy Bridge, so I would say you are risking the CPU a little bit, but not overly so. Temperatures are good though.

Less voltage and taking the core clocks down a notch is probably worth it if want it to last a while. Might be a setting for LLC or Load Line Calibration, you might be able to increase that setting and not have to use so much brute force voltage.

CPU PLL backwards? Stock 1.8 or stock 1.7?

VID is a table of voltages stored on the CPU. That is what the CPU wants as a core voltage, you are exceeding that, so they can be disregarded.

Can't really say anything else without knowing which CPU. Assuming Skylake, Kabylake, or Coffeelake, this is beyond what is considered 'daily use'. 1.4 volts being the recommended maximum. Fixed voltage and fixed clocks? Some serious droop there, might want to look at load line calibration settings and reduce overall voltage.

77C is pretty good though. Water cooling?

This Is i7 3770K dellided. I set up in BIOS:
Clock ratio: 45
PLL overvoltage Enabled
Turbo boost technology Disabled
Hyper threading enabled
CPU Enhanced Halt (C1E) Disabled
C3/C6 Stare Support Disabled
CPU thermal monitor Disabled
CPU EISTN Function Disabled

Voltages:
CPU Vcore 1.260 i set up 1.460V
QPI/VTT Voltages 1.050 i set up 1.080V
CPU PLL 1.800 i set up 1.700V
For Memory - Turbo multiplier 16

Every time i set VCore Power thank 1.460, system Is really unstable. So will this Voltages degradate CPU? Should I change something?

My Rig:
I7 3770k @4.5GHz, Cooler Master Hyper 212Evo (double cooler)
Gigabyte Z68X UD4 B3, 16 Phase Power Design
4x4Gb Crucial Ballistix Tactical Tracer 1600
MSI Gaming Z GTX 1070 8Gb
PSU Chieftec Evo 600W 45A, modular, 85% efficiency

PLL stock is 1.800 and I dropped to 1.700. I cannot find option for Load Line Callibration in BIOS. Here are the pictures:

How to set LLC?

I would say try raising your PLL back up a little bit, see if stability improves. Doing that to keep temperatures down is all well and good until there isn't enough power to run the chip. Might also explain your pretty large voltage droop.

LLC is called Multi-Steps Load-Line on this model, but the manual calls it Load Line Calibration anyway, hmm.

I guess my MoBo doesn't have it. I just tried raising up or down voltages of VCore or PLL and it is unstable. I set it up like before.
I hope this voltages will not damage cpu.

Thanks for your help.
