I9 9900k

4.9 and not the mythical 5....that's going to gnaw away at you, won't it :D

It's only 100mhz but that 5GHz number seems to make all the difference.

Even people who can push their cpu to 5.1/2/3 are happy to clock back to 5GHz for cooler temps but don't want to go lower. We're a funny species. I include myself in there amongst the odd ones :D

Don't torture me man, it's already making me think the 9900k is sh** lol yeah, I've considering a custom loop but no one has replied to my noobs request

If the custom loop doesn't work then you can always delid.

It worked for this guy.


Depending on how you've done in the lottery it might not be required.

Just get the Intel OC insurance and return it, another crack at the lottery!

Although just had a look for 9900k and it does not look like it's available for that CPU, interesting, whys that??

I literally have the worst 9900k. Oh well. Anyone else on the forum sub 5ghz. My cinebench score is 2150ish, is that right ?

I've seen plenty of 5GHz all core scores in the 2150s and some lower, some higher.
Obviously this depends on your ram and what other processes are running, but it's right where you should be given there is only 100MHz difference.

It has never been available for the 9th gen. I don't know why, perhaps the supply issue has something to do with it.
 
Okay, so today i'm trying a new method.

I have set all turbo cores to 5ghz, avx to drop to 4.7ghz, LLC on turbo and tjmax to 95c as my chip is crud and constantly throttles in torture. I'll see how stable this is

I'm running vcore and all the rest on auto until i can determine what else to change, i quite like the variable clock and low power/heat method i used to run on my 5820k.

You shouldn't run vcore auto as most boards (esp gigabyte) will give you an unresonable high vcore which will just add more temps and worsen the throttling issue.

You're not going to come out ahead in this overclocking experience with running vcore on auto.

Well i've followed every single overclocking guide and my cpu can not get stable at 5ghz 1.35 vcore like everyone else, and that's with llc turbo or extreme. I've even tried fixed and variable clock with a vcore of normal with an offset but nothing is working. I just have a really really bad chip.

Just to point out i'm no stranger to overclocking and my 2600k and 5820k overclocked beautifully and are still going strong today.

With my current variable clock and auto settings its running stable and not going upto 1.5 vcore

all turbo cores at 5.0ghz, llc turbo, tjmaxx 95, avx offset 3 (4.7ghz). This is just my basic foundation that i'm starting off at as even just using 'enhanced multicore performance' will cause my pc to die during gaming.

Maybe it's the auorus ultra board, maybe i'm just bad at lottery

What's the lowest vcore it will do 4.9GHz at? Have you tried lowering the llc? Having it too high can introduce instability, it has cropped up a few times with gigabyte llc settings.

sorry to jump in mines does it at 1.3v with llc to Turbo. at a nice 91c under load...

on the other hand my Aorus Master Pro runs cool as heaven 39c on the VRMS under 20 minutes of stress incredible


heres a pic of my 9900k.

Defo won the lotto with this one...

Interesting comment about delidding that may be of interest. From reddit.

"What temperature when you run small FFTs?

I would recommend to delid and direct die. That’s the only way for me to made my dud 9900K finally stable at 1.38v with LLC 6 (equivalent to Turbo).

Before delid I can only achieve 4.8 GHz with AVX offset 1.

After delid but before direct die I can achieve 5.0 GHz with AVX offset 2.

Then after direct die I can achieve 5.0 GHz without offset and bonus 4.7 GHz cache (previously max at 4.4 GHz).

Take my recommendation or not is up to you since it will void your warranty and extra job done.

This of course is not necessary if your chip is good but it looks like not the case."

They aren't the only one that has had a cpu that wouldn't do 5GHz that has seen it hit 5GHz after delid, so it is not an isolated case.
