Question Asking for advices, guide to complete my 9900K OC

[Epifiano]

Hi guys, I am trying to OC my 9900K.
I am able to reach 5ghz with 1.270V, problem is not stable for realbench getting high temps, after few minutes, occt and prime on small fft getting most of the times BSOD or high temps >95C too quick but I am able to do cinebench with 88 average degress 5150 points, and I tested 4 or 5 games with high demand without any issues at 60ºC max.
I think that maybe I need some fine tuning with some advices of people who really know much more about OC than me. Its the first time I am doing OC but at least I´ve been one hole week looking tutorials, testing, etc, but still a noob, must confess and every time I search for a new tutorial I feel even more lost and confused.

I´ve been following youtube guides, tutorials on webpages and forums, and I really can´t figure it out which one is the good one because practically every one has a different config. (some of them use XMP 1, others 2, some of them have svid activated, others disabled, some uses 45 core caché, others said to start on 43, others 47, and same with other options, so I am reaching a point where I dont know where am I, and what I should change or not.)

My pc specs
Asus Rog Strix z390 F gaming
AIO Corsair H100i (The Old One)
RAM Corsair Vengeance 3000mhz
Nvidia Geforce RTX 2070

Im going to post what I have actually on my bios and see if someone can help me fine tuning this, because I have the feeling its not only a voltage thing the problem I have....

My UEFI Options
AI OVerclock Tuner XMP I ( I go with XMP I because I read on some forums normally is more stable than II, but tried both)
BCLK Freq 100.000
ASus multi core enhacement Disabled, enforce all limits
SVID Behaviour Auto
AVX 0
CPU Core Ratio Sync all cores
Core Ratio 50
DRAM Odd Ratio Mode Enabled
DRAM Freq 3000Mhz
CPU SViD Support Disabled
CPU Core / Caché Current Limit Max. 255.75
Min CPU Caché Ratio 45
Max Cache Ratio 45
BCLK Adapt Voltage Disabled
CPU Core Voltage Manual
CPU Core Voltage 1.270
DRAM Voltage 1.350
CPU VCCIO 1.100
CPU System Agent Voltage 1.100

DIGI+POWER CONTROL
CPU Load Line Calib Level 6
Synch ACDC Loadline Disabled
CPU Current Capacity 140%

INTERNAL CPU MANAGEMENT
Intel SpeedStep Disabled
Turbo Mode Enabled
Long Duration 4095
Package Power 127
Short Duration Package power 4095

CPU POWER MANAGEMENT
Intel Speed Step Disabled
Intel Speed SHift Disabled
CPU C- States Disabled
GFG Lock Disabled

I mean, I can live with that and If I need to do some premiere etc, load the stock profile on bios and then changing for gaming again on uefi profiles, but If I can find something stable for everything it will be really great.

Hope somebody will find something I have wrong to get some improvement, I really dont want to push much more the voltage, considering I am reaching already some bad temps with this voltage (Which surprises me because I though my refrigeration was way more effective than it really is...)

Thanks in advance.

The issue is your cooler. Even though the H100i is a good cooler, the 9900k runs absurdly hot.

You are going to be looking at a 280mm for good temps at stock, and a 360mm for good temps when overclocked.

 

[Epifiano]

I knew that my cooler was not the best because of the temps, and I´ve been checking the corsair h115i pro which is 360mm i think right?
The problem is it need another case, because doesnt fit in my corsair vengenace c70, and I´ve been checking a bit quickly and saw that the prices for the cases I need are from 150€ minimum, which is pretty much the same than the AIO cost, which in total is more than 300€ only to change cooler, so I will try in the future to obtain something like that but atm I think I am gonna pass, lets see if in black friday a good offer appears. Any recommendation about case to consider for the future?

In other way, I know its really bad my cooler etc, but there is nothing else than can be fine tuned on my config to make it more stable? I am already playing with the computer at 5ghz with no probs of temperature, Im just looking for a bit more stability if possible.

Another question, is possible that the noctua which is air cooler is better than my h100i? Ive read that a lot of people with that cooler is been able to OC to 5ghz this i9, How is possible air cooler is better than liquid AIO? (I said I am already noob, so I am sorry if the question is a dumb question)

Thanks for reply

 

[NightHawkRMX]

You said 5ghz ran at 95c and was unstable.

To make it stable you would need more voltage whuch would cause throttling.

Leave it it stock for now.

Liquid cooling is not a magic bullet. Air coolers can perform just as well.

A noctua nhd15s would be better than your current aio and comperable to a 280mm, which may allow you to get 5ghz with high temps.

 

[Epifiano]

Yea Ive ran at 95ºc but only with prime and this stuff, gaming doesnt pass 60ºC and never get a crash gaming.

That is why I was keeping asking, because I know some people is able to run 5ghz at 1.25V, and I thought maybe my config was not totally fine tuned, not only for now, asking for the future too when I will have better cooler, to know what can I improve, but I guess if you dont say anything about my config it means everything is ok and only the voltage is the problem.

Thanks for the explanation of the noctua, never expect that an air cooler could be better than aios.

And again, thanks for replying, much apreciatted.

The i9-9900k is a beast in both performance and temperature.

Remember, all chips are NOT created equal and people aren't likely to post about mediocre overclocking ability. This means that most of what you read online is the top 1%, so take it with a grain of salt.

I can do 5Ghz with my i9-9900k as well but it's not stable over time with heavy load. Temps rocket up and it ends up throttling. I am happy with a locked 4.8 (ring at 4.6) at a peak of 1.255v. I'm using the H80i v2.

I might try the intel performance maximizer app.

It will take into consideration the performance of your cpu, motherboard, cooler... and do the best it can with what you have.

Sounds like you have an average chip.

As of 2/6/2019 from silicon lottery:
What percent can get an overclock at a somewhat sane vcore in the 1.275v to 1.312
And AVX offset = 2.

I9-9900K
4.8 100%
4.9 86%
5.0 39%
5.1 8%

Aside from academic interest, how much do you really need that last multiplier?

 

[Epifiano]

Thank you guys for the comments.

Maybe my lack of english didnt let me express myself correctly.

I am not interested on reaching any record or anything like that at all, and I am well aware that people with 5ghz at 1.25 is really a minority, but I thought that maybe 1.27 - 1.28V considering I´ve seen that a lot of people with my voltage was not able even to start windows was maybe possible to reach for me (stable) for prime and benchmarks.

As I said before too, I´ve seen that everybody on their tutorials uses different configs and there arent 2 guys with same exact config, so I tought that maybe something in my config was misfit.

My only intention is to keep all the cores at same speed and at highest possible performance all the time (with the posibilities of my setup) to be able to play iracing on VR which is really cpu demandant and to be able to play without any frame drops, because at stock speed I was always getting some frame drops( I think because of the change of voltages, differents speeds on the core etc...) because since I pushed it all to 5ghz I dont get any more that frame drops (At least in the test I did few days ago) the thing is, I am more than happy if I am able to play with that and as I said, if I have to do the rest of the things on the pc like rendering etc I have to restart and load stock bios profiles, its fine, but my asking was to try to avoid that step of changing profiles which in long term I guess is going to be tedious.

I am not trying to say neither that I want 5ghz at all cost, If I have to down to 4.9-4.8 on all cores and I dont see that frame drops I am happy too, again, not interested on any benchmark record or racing at all, just my own confort to be able to play in the best possible conditions with my setup.

I am pretty sure that in black friday I´ll get the corsair 150i pro, a case for that (I dont know yet which one is better at low cost) and hopefully will be able to maintain 5ghz stable pushing a bit more the voltage with good temps.

I´ll check that software, thanks again.

Just out of curiosity, are these quoted Vcore numbers what you would type in in bios, or what you see in CPU-Z while stress testing? I’m just getting into my first OC and noticed that there is a big difference between those two numbers and I can never tell which version people are referring to.

 

[geofelt]

The voltage you ask for may not be what you get.
It gets complicated and I am no expert on the inner workings.
But, in general, the motherboard will try to provide sufficient voltage to run the multiplier you ask for.
If your settings are insufficient, the overclock fails and you try again.
Somewhere along the line, there is a true max before damage. I think that might be 1.5v.
Not that you want to go anywhere near there.
It is the high voltage that causes heat and thermal throttling or shutdown. That point is around 100c.
From what I can see, one tends to run out of a tolerable vcore before running out of thermal headroom.
Some tests I have read with the 9900KS running at 5.0 on all cores and having thermal issues gives me to question that assertion, at least for the 9900KS
No doubt,running at a high voltage will ultimately reduce the longevity of the chip.
I think a mildly elevated voltage overclock is fine.
Within conservative limits, the processor will be obsolete before it fails.
