i5 9600k overclock

[lizart951]

I have z390 aorus pro,Noctua NH-U9S,brand new Corsair rm750x and of course i5 9600k .I followed a few videos and guides on how to OC-it but with no success not even once i got ot the OS.The bios version is f11 not the latest and will try to update in tomorrow if needed.So the videos are from 2019 and some stuff are in different places in the BIOS and the names of the things are different even that i spend 5 hours now maybe in reading and trying ...nothing works.I know the silicone lottery and that every chip differs from one another.But what i need to do in order to get it to lets say 4.8 GHz for now?

at first your cpu needs to be able to go that high. a K isn't a K in regard of how far you can overclock...

 

start in smaller steps... 100 mhz each time and test the stability of your system. repeat until you reach the point where a boot or stable os isn't in it anymore, revert to the settings from before and be a happy camper.

My 9600k can do 4.8GHz all core with absolutely no instability at 1.3v and an AVX offset of 3 if I keep the temps below 80C. You could probably start with that. Obviously, your chip is going to be a little different, but I'd imagine most could do 4.8GHz all core at 1.3v.

 

That OC seems stable at as low as 1.27v too, but I haven't used it there enough to confirm that no issues ever happen.

 

And it takes 1.35v and AVX offset of 5 to let me do 5GHz all core, but sadly it's not 100% stable - I actually was just trying that OC again and Control crashed when I tried to fast travel after I'd been playing it for a bit. Temps were under 60C when the crash happened, so it isn't too hot. I'm guessing my chip just needs more voltage. I'd prefer not to have to go to above 1.35v, so I may just settle for 4.9GHz all core, but perhaps I could give it a try at 1.355v to see if that pushes it over the edge and makes it stable.

What other than cpu ratio avx offset and voltage i need to change? I will do small steps 4.8 all core is good for me.

If it takes 1.3v just to get 4.8 on a 9600k, then why does an 11900k need upwards of 1.5v to get 5.3ghz?

Seems like rocket lake and coffee lake have similar voltages for ocing prob because 14nm.

 

Heck i needed 1.8v vcore and 2v pll just to get an e5800 to 5ghz and thats just in the bios, so i guess the transistor size does have a role in how much volts you need for ocing other than chip binning, seems like i just got a crappy sample.

 

I think you will have to determine what voltage your all core oc is stable at, lower the voltage the higher the clocks = better binned cpu.

Higher voltage lower clock = garbage binned cpu.

Thing is that i watched der8auer's video on the topic another youtuber from my country tweaktown also has a video on the topic read and oc guide too and nothing works.It goes on 4,6GHz all cores why can't 4.8 GHz it's not that big of a step.

@lizart951 Did you go into the BIOS and increase both turbo power limits? Many Intel CPUs will throttle if the turbo power limits are set to their default values.  

 

When your CPU is loaded, run HWiNFO and find out why your CPU is not running at the full speed that you have set in the BIOS. 

There might be a clue in this list of throttling reasons.

Higher voltage lower clock = garbage binned cpu.

The higher you go the more voltage you need for the next 100mhz isn't linear

 

my 10900kf: 5ghz all core needs 1.15v, 5.1ghz needs 1.28v, and 5.2ghz needs 1.4v(all load voltages). At 1.4v load it becomes impossible to cool.

 

Hell at 1.3v it's already difficult

where in the bios i can find this power limits? Or atleast their names.Tried today 4.8 it's stable under aida64 fpu and cpu stress but it needs alot of voltage 1.335 after sometime it started to crash when gaming and random bsods so i got it back to 4.6 .

p.s Everything from this tab is No like yours but i don't have that much things

My Asus BIOS has them in the AI Tweaker section.

The Long and Short Duration Package Power Limits. 

These are also known as PL1 and PL2.

Max those limits.. Just say no to AVX offsets.. it’ll be fine at 100c briefly, and I know it’s fine in the lower 90s.
