5gz i5 9600KF won't boot into Windows

[empleat]

Hello, 

 

i have trouble overclocking i5 9600kf to 5ghz, can you help me plz?

 

Despite i5 9600KF popular CPU for overclocking, didn't find any good guides on youtube/google. I copied pretty much this guide: 

My specs in attachment. Also I made picture from video for your ease: https://imgur.com/a/Uppbi42

 

When I select disable all enforcements, it changes once i enter ratio like 50 in filed under sync all cores to ASUS managed - strange! But I can manually set to disabled after i set multiplier to 50! I tried both and windows didn't boot on 50. But it boots on 49. I set 1.34v on core, i am going to try yet 1.35, no idea what is the issue! Why it wouldn't boot on 5ghz. I Am on ASUS z390-i gaming, it has limit 140% of current in LLC/VRM section. Maybe it can't OC above 4.9? I need every bit on Resident Evil 4, it maxes out CPU!!!

 

On second hand voltage should be enough, it was overclocked on to 5100mhz (tho don't know what CPU): https://www.anandtech.com/show/13840/tiny-at-200-usd-asus-rog-strix-z390-i-gaming-asrock-z390-phantom-gaming-itx-ac-review/9 Also what about min/max cache ratio, to what i should set this. I didn't check frequency of it in BIOS yet.

You could be simply running into the silicon lottery on your chip. Maybe your chip just isn't a good enough sample to go above 5Ghz.

Some CPU's overclock worse than others. Its all about winning that silicon lottery!  There won't be much difference between 4.9ghz and 5ghz realisticaly.  If you can keep it stable at 1.34v at 4.9ghz that would be plenty.

[empleat]

I set avx offset to 2 and min cache to 43 and max cache to 46. Core voltage 1.35v. I was able to boot without BSOD, but then at login my screen frozen and i had black screen had to turn off PC, since restart didn't work. And BIOS booted in safe mode. Yeah if I can't even boot on 50... 4.9ghz will be hopefully fine, i will let you know if i need to stabilize it.

4.9Ghz is already pretty good. Even if you do manage to boot and not bsod right away you'd still need to do hours of testing for stability, good luck and be careful with your hardware. 

[empleat]

My cooler: Dark Rock Slim be quitet might not be enough. This is 4.9ghz/1.35v AVX offset 3, min core cache 43, max 46... And it is not even full summer... Hmm strange, i was checking from tests and this cooler should be enough. Maybe i need re-paste bit better, but it is hard to do with my large hands... I can still reduce voltage/LLC and tweak something perhaps... Oh no I want at least 4.9ghz, that is horrible so overeating! 

 

[Fred Castellum]

Those are absolutely fine idle temps.

[empleat]

Max temps 90, CPU package reached 90 and one core tho! Sry bad picture kinda.

 

This must be some error no? It shows Core0 is boosting to 5160mhz!!!

Damn hwinfo shows 61 when idle in windows, but on tray 38, which is more likely. I Am running latest version, seems monitoring is bugged simply, because that doesn't seem possible... I have installed SMbus drivers, don't know maybe this version is broken? Version: 7.46-5110

 

EDIT: I will use 7.00-4400, shows correct values...

 

Any idea how to lower temperature on LLC 5 still reaches 87C max, i will try yet low LLC and voltage, maybe AVX, which is 3 now and core cache min 43 and cache max 46 (what should i set these to?). Also what about phase control and power duty, and what about switching frequency, these affect only VRM temps mainly no? I currently put them on extreme, switching frequency 500mhz, I was bit worried since I was lowering LLC.

 

Maybe need repaste too, but it is hard with my extremely large hands and I have trouble estimating how much and putting it on edges also, i don't want it to get between socket and cpu... I have one of best thermal pastes already - Thermal Grizzly Kryonaut. Not sure how much room for improvement there is!

 

What when i play resident evil 4, it shows CPU boosts only to 4600mhz??? Do games use AVX??? But i have like +20-30fps it is crazy and CPU is near maxed all the time! Wow if i knew this, from what i read it 9600KF should be more than enough for RTX 3070, except maybe CPU intensive games...

 

Hmm it was luck don't have that many still drops under 60fps damn  Or alt+tab messed something up...

 

It helped a lot, during fights drops to 56, instead of 40, but it still sucks, aim is like underwater bit... I had same problem on my old PC in Battlefield 1, could just crank 56 fps on high it sucked! At least CPU temp is fine not even max. 70 for now...

 

Even 9700 on auction is expensive... I can run mb. didn't test much yet 4.9 with avx 1, but doubt it will help that much i get drops in intense fights to 46 even...

 

EDIT: getting to 4.9ghz avc 1 helped a lot, if i could get at least 4.9, CPU rarely maxes out, it is nearly 100% maxed, just right under, aaaaaaaaa, I need bit of jolt yet. What do I doooo?! I don't want lower details this game looks so beuatiful, i was waiting for this years!!! And DLSS is blurry AF even on quality 

 

4.9ghz/1.35v

avx 1

core cache min 43

core cahce max 46

LLC 6

switching freq. 500hz

duty control and power phase extreme

 

Bios estimated i would need like 1.370v for 4800avx

 

I don't think there is anything i can do, i will need to lower some details i guess and tweak it so it is playable... Don't want to buy new used cpu for 250, or risk OCing more...

 

Damn and yet game is crashing on 4.8avx, it is unstable still, can't get even 4.8ghz damn, useless...

 

I tried switch on resizable bar in BIOS but in NVCP is says: no. NOOOOOOOOOOOOOO :(((

 

I tried to turn it on in Nvidia Inspector and it definitely boosted fps, now intense fight scene is barely playable. Damn, I can't get past 4.7ghz avx under 1.35v  I just need tiny boost! This is joke! I will also OC ram and GPU even more probably... 

 

Can you help me OC to 4.8/4.9 safely? Overheating was insane tho, not sure if it is doable! I can't do that right now aways, i won't be home to test re-paste, but doubt it will help that much, I want to try OC it now if possible! I will also try repaste and answer to this threat later! Maybe in combination with lowering some details, i don't know what to lower tho, it is pretty tight!

 

I don't know read something that core cache at 4.5ghz and lowering actually voltage might do it for 5ghz etc. overclocks: https://www.overclock.net/threads/9th-gen-core-i5-9600k-overclocking-breakthrough.1794356/ That 1.35v might be too high! Do you think I could get at least to 4.9ghz somehow?

 

I need really boost CPU as much as I can even with lowering of some details!!!

 

EDIT 2: 

AAAAh I forgot to set cpu package power to max. But it is overheating af, reaching 85C in Prime 95, will have to test it in game yet... On voltage 1.33. Doubt I can get past 4800mhz on safe voltage... 

 

Question: motherboard says maximum CPU current capability 255.50, but it can be set to 255.75. Can i set it to latter? 

 

Also why one of my core reaching only like 25% usage (core1)? In prime95, even when i click on it, i found if it wasn't in foreground it didn't utilize all CPU in past, but it seems to do now, still even when i clicked on Prime 95 task bar to move it foreground core 1 is not utilized in test!

 

Question: do you know something which turns off computer at certain temps, for nighttime testing?

[empleat]

I don't think there is any way I can get above 4800AVX! Currently

Quote

4800AVX

1.35v

LLC5

max cache ratio 45

I can't even go to LLC 5 from 6 on 1.33v, without immediately crashing Prime 95

It says to 4800mhz in BIOS already 1.37v. But it works on 1.33 with LLC 6, or it seems it works on 1.35 LLC 5.

 

I think I keep 1.35v LLC5, since I don't think you are supposed to run with LLC6 long-term! Also temps already get up to 85! Tho this is prime, in game they are lower I think, so there is probably some room!

 

There are also some advanced tweaks, I don't think I can cut it tho on <= 1.35v. Do you think with some special tweaks I could get to 4.9ghz somehow?

 

Also why my Core 1 has mostly only like 25% current usage in Prime 95? Oh i noticed one worker always stops!

Your overclock is not stable on that core.

[empleat]

And why is that? I put sync on all cores 48. Do you think I should do per core then, maybe it will go higher?!

[Mister Woof]

100mhz won't make a significant difference in performance

 

mostly it won't make the architecture better, give you more cores, or SMT

 

it's a lot of work to do this and you'd probably be better off spending it just playing RE4 with a little stutter

[empleat]

I already reached when it shows in HWINFO like CPU USAGE under 90%, or over 90 slightly, not tested long time (also in task manager it shows 100% i think - so i am not sure which is it)! But yeah I don't think I can get much more out of this! When already 4800AVX takes LLC 5 and 1.35v! Now yet stabilize GPU OC and RAM OC, I NEED every fps I can get  

 

Can i RUN LLC6 long time + 1,33v? Pc crashed completely and restarted with sound loops before! It seemed stable before. I run now 1.35v LLC5. I need at least 4800mhz tho! Or should I risk setting 1.37v in BIOS?

 

Seems core 1 is unstable, either way it was worker stopped, hardware failure in prime 95 under core 1!

 

Seems like my CPU is starved for power, i selected in BIOS per core and set core 6 to 47, as it doesn't let me select this for core 1, all other cores behind it lower to 47, when i enter 47! And now no workers are stopping! I have already VCCIO and VCCSA set to 1.1v. How can i free power for CPU pls??? Should i set also perhaps 1.36v, it shows in BIOS 1.341, but these readings are not realiable, oh not still hardware failure detected and core 2 stops... DAMN I need at least 4800mhz, what do I do? Core current limit is 255.75. Maybe lower core cache frequency from 4500mhz? What do I do? I need at least 4800, otherwise my CPU is maxed!!!

 

Worker failure even on  LLC6 and 1.35v damn!!!

[Fred Castellum]

Your going to fry your CPU at this rate. What you should be doing is increasing your overclock in increments and testing for stability in each increment before trying to push for higher speeds. You already have instability on core 1, that means you need to dial back or change existing settings and retest for stability. 

As @Mister Woofsaid, the performance difference is minuscule for another 100mhz. Your probably at the limit of what your chip can do, either do proper incremental testing with your overclocking or just stop at a previous stable point and just play your game.  

[empleat]

I thought under 1.35v, it is considered safe!

 

Damn even on 4700mhz, worker stopped on 1.35v, and LLC5. Hmmm... How it can be so garbage, not even 4700 now? It is not probable that even 4700 wouldn't work. Can you help me?

 

It is weird even BIOS says 4700AVX should work on 1.33v!

[YoungBlade]

It's very possible that you got a weak chip when it comes to overclocking. My own 9600K could never be stable above 4.8GHz, at least not at the voltages I was willing to give it.

 

But, even in the brief glimpses of 5GHz that I got, I can tell you that those extra 200MHz don't do much.

 

If you can get an all-core around 4.7-4.9GHz, you'll be getting basically max real-world performance from the 9600K. I found that 4.8GHz was a noticeable improvement over the stock 4.3GHz all-core, so would occasionally use that OC for more intensive games.

 

Why didn't I just run it all the time? Because it ran very hot, and I didn't think the efficiency trade-off was worth 10% more performance most of the time.

[empleat]

Problem is i AM maxed on CPU 4700mhz, but 4800mhz not! Game is very tight, i need every fps i can get!!! Sniping is lagged as hell!

 

I Am running now the game like 2 hours on 4700mhz, 1.335v and LLC5 without crash! Even Prime 95 stopped worker, but it is most demanding benchmark there is! Problem with 4800mhz, it is not stable at 1.35v LLC 5/6 and it heats as hell gets up to 85C, maybe slightly above! Don't know if it is possible on this cooler - Dark Rock Slim be quiet! Problem it says in BIOS that it would need like 1.37v, but it is already overheating AF! Maybe i can try with lower LLC? I think actually LLC causing too much overheat! I now had only 72C max in-game on this setting. But I don't think I can run stable 4800 <=1.35v in any case!

 

What about tweaking paradise, and some other setting, are they worth checking in for OC? I would be very happy if I got at least to 4800mhz, it is bottlenecking my GPU and game is already very tight, I can't find anything to lower really without drastically worsening quality, but i enjoy its atmosphere and beautiful graphics so much. 7 years not any game catched my eye really like this one... And I need relax on chronic pain! 

 

Pls pls pls, is there some way to get to 4800mhz? Really need this!!!

 

I don't understand much LLC and voltage. Maybe I should also test different LLC and going from them to different voltages. How Am I supposed to know which is enough! And also overshoot could cause instability at higher LLC and voltage no? I never did overclocking really, my old PC i had 8 years, i built it with 40$ mobo and it run absolutely fine years 3770+780...

 

Also for overnight testing, i need some safety like shutting down pc above temperature 85C etc. Ideally if only for longer periods, not if it just jumps for 5 sec to 86C etc.

 

I will try to find lowest LLC and voltage on 4700 for now and use like AIDA for benchmarking since Prime 95 is overkill, but i need something to shutdown PC, if temps too high overnight...

 

WELL I THINK I WILL LEAVE IT FOR LIKE 15 DAYS LATER, I AM GOING ON VACATION soon, DON'T WANT MESS WITH IT NOW PAST SAFE LIMITS... i am just glad it runs on 4700 now... need repaste after that too, there is too much overheat at 1.35v/6 LLC!!!

 

ANY IDEAS HOW TO GET TO 4800MHZ ARE WELCOMED!!!

[Ebony Falcon]

Reset bios to default and enable xmp 

leave cache alone for now 

set llc to level 6 

and vcore to manual mode at 1.35v 

add 100 mhz to core clock boot and run something like r23 for a quick check.

If u pass add 100 mhz again untill r23 crashes.

then go back 100mhz.

 

now it’s time to run prime or aida or a real stress test, you want a minimum of 4 hours testing to pass.

 

then you go to cache. Set minimum and maximum to the same number. Say 4.4ghz on both and test r23 again. Pass add 100 mhz to both u till u fail then go back 100mhz and run the propper stress tests. 
 

you also need to monitor temps at all times. Once you have something dialed In and ur cooling can handle it feel free to do 24hour stress this will give you ur max oc

 

most likely once ur stable u can reduce clocks on each by another 100mhz and start lowering voltage to have significant temp drops for 97 percent of the performance 

 

9600 isn’t high quality silicon so I would expect 4.9 on the core and 4.5 on the cache for max oc 

 

and 4.8 and 4.5 for a decent daily oc with good temps in the 1.3v range 

[empleat]

OK I actually found issue, I am already at 175W TDP, my cooler has 180W TDP!!! 4800 is too unstable on 1.35v and LLC6, in load VCore drops, because overheating! There is no way it will go past 4700mhz and actually 8600kf is most overclockable chip from 9xxx what I read on some overclocking site! Like 80% should do 48/49... Guess I had really bad luck on chip... As it is even possible to reach 5ghz on stock cooler sometimes...
