I need some tips what to do in the BIOS, to overclock my CPU, (i have great exp overclocking GPUs, but no exp from CPUs)

I am aiming my CPU to 4.5 GHz. My specs are listed on my profile.

Thanks :)
 
Hi , why 4.5 GHz ? You have your board, and your CPU slowly high clocking and try again . You can not do not have what you are to accurately set . Each board and each CPU is different. How much experience do you have in overclocking ?
 
Read you first the basics of which are important for overclocking . Just what other people have to adjust set me personally would be too risky . Read you through the guides and slowly try you forward . Otherwise, you may destroy quickly your hardware .
 
Hi! I watched this tutorial and was thinking about min and max cpu cache ratio: on the video, guy have 4790K and he putted 40 on cache ratio, so i should put 34 on that ?

 
Try it. you can do it just by testing out . grope in small increments to your targeted frequency . The voltages please be careful . Ensure sufficient cooling and when the are highlighted in yellow slowly increase . In red voltages it is dangerous for your hardware .

I can tell you that my CPU with 4300 MHz is stable . 24/7 . If I raise to 4400 MHz , then I get after 2 hours a blue screen .

I used Asus AI Suite 3, 4670K on Z87-A, don't know if it's same for your board. It has 1-click-overclock option. Got my CPU to 4.2, no problems since. Only thing, don't run Prime95 afterwards. Watch the video,
 
This is what I would do. I would just set your voltage to 1.35, set your multi to 45 (if it won't boot, it's not capable of 4.5GHz at safe settings IMO. drop multi to 44 and try for 4.4GHz), test for stability, reduce voltage 2 clicks, test for stability, keep reducing voltage and testing stability until you get a crash. once you get a crash, go back to the last good voltage setting and test for long term stability (24-48 hours). OC'ing in it's most basic form.

Ok, so you suggest only multi and voltage? So no other settings like in video i posted?


What should Min/Max CPU cache ratio be? if lets say 4670k 4.5GHz?

1.250V, 4.3GHz=stable
1.250V, 4.4GHz=BSOD
1.3V, 4.4GHz=stable
1.3V, 4.5GHz=BSOD

so i guess i lost silicon lottery :(
At the moment BIOS settings are:
Sync all cores
Multiplier 4.4GHz
Core voltage 1.3V
 
OK i managed to get it 4.4ghz with 1.288v manual voltage , so manual means ny voltage is stable 1.288v load or idle. My computer is in Daily use and sometimes on overnight, will this voltage BE dangerous?

Me too, my Ivy Bridge i5 needs 1.3 V for stable 4.2 GHz and with mid range air cooler like mine it can reach 80 C if heavily loaded, but voltages are dynamic and it's up to 1.3V only with turbo and 100% on all cores

Your board has hefty heatsinks on the VRM but running 1.288 V all the time will generate unnecessary heat and somewhat reduce life of the VRM. Reduction might be insignificant compared to the lifetime of the board but that mostly depends on quality of components (mosfets/integrated power stages) and proximity of the capacitors to the heatsink. I'd consider it only with good case airflow.
Why don't you try dynamic voltages using different load line calibration setting?

you should be able to get the same oc but much lower idle volts+temp with offset mode.
loadline is just for stability of vcore-so if ya put loadline to 7 it should stay near 1,288v
 
it seems my 4.4ghz at 1.288 wasnt stable because it crashed playing eso, it seems to be stable at 1.3v running ibt very high 20 runs, but i put it to 4.3ghz which is stable with 1.22v, pretty bad chip to get 4.3ghz at 1.22v but cant do 4.4ghz until 1.3v :(
 
Currently running 4.3GHz @1.23v (manual). Because my voltages are manual(to get better stability) my idle and load voltages are constant 1.23v. Would this be dangerous? I have good motherboard with good cooling and airflow.
 
Voltages are really only important because they determine temperatures. If at idle your CPU is less than 40C o then you should be fine. And while gaming, if your CPU is less than 70C then that should be OK too.
 
OK but doesnt voltages affect mobos and cpus life like age Wise ?

not in any real measurable sense
cpus have a life span of 15 or 20 years
so even if you are running 1.30v you are only cutting that down to 10 or more
