AsRock P67 Pro3 + I7 2600K OC help

[EarthDog]

Is it just me or did the voltage in Hwmonitor not change... especially the VID?

Are you sure level 5 is the max or the minimum? Sometimes its the opposite.

4.4 GHz at 1.45V (BIOS) has got to be the worst chip I've seen.

Yes you told that few times, that my 2600k is worst you ever seen.
Voltage in HWmonitor is changing both places, in VID with more dynamic, I can record video?

I try offset mode. With +0.50 got bsod after 6-7minutes. With +0.75, Additional voltage +0.20, PPL Enabled and LLC Level 5 (5 is higher, 1 is lower, I will try with level1)
I got stable 4.4 with max temp of 82c. My voltage is ~ 1.34?

4.4 @ 1.35v is pretty good.

 

[EarthDog]

1.35 is better.

your voltage is jumping since you are enabled Intel energy efficiency and using offset mode .
You can disable them in bios and set voltage to fixed .

 

[netaccs]

Which setting is Intel Energy efficiency, cause I disabled most of them. I think offset is better, cause when cpu is not under load it drops to 1v?

I got also 4.5GHz with same settings. Vcore i 1.35 max temps 82.

different intel c state (c1e) , intel speed step (EIST) , limit cpuid max , overspeed protection . i prefer to disable all those to make sure motherboard is not limiting processor power , also some time reducing vcore and switching frequency high and low cause instability .
start with fixed voltage once you got stable you can try to play with auto voltage/freq drop if you are not comfortable with fixed speed/voltage.

 

[netaccs]

All of them are disabled, including lpt port, intel virtualization, c1, c6 any power saving future.
I am glad from this settings + my hardware.
Anyway, will try 4.8 just for sport.
I know, have to be very careful with voltage.
1.5v is something like maximum right?

 

[makaka]

1.45 is considered max safe , but for quick bench 1.5, 1.55 should no hurt if you keep temp under control ,

i wouldnt even go that high my 2500k degraded at 1.42v ... that was 4.9ghz though... now to keep it stable i cranked it down to 4.7ghz and 1.375v

i wrote about sandy-bridge degradation some time ago : https://www.overclockers.com/forums/showthread.php/792373-Sandybridge-CPU-degradation-overtime .so 1.42 was stable @ 4.9 ghz then degraded ? how much time it required ? maybe 1.42 was not stable enough at start ? . Each cpu is different , also we should take on consideration psu , cooling , motherboard , diff bios energy save setting etc ...
for me personally if it take 10 year for cpu to degrade from 4.9@ 1.42v to 1.55v it is quite ok since cpu in 10 year will be trash anyway .

 

[EarthDog]

I pounded on those CPUs at 1.4+ for quite a while and was OK. They start at like 1.25V give or take anyway.
