I have been trying for 2 days now to get to a stable overclock but I get bluescreen errors every time I try and run cinebench r23 the only time I have been able to run cinebench without issues is when I have my cpu set to 4.9Ghz at 1.34 volts the temps are good but I can't get to a stable 5ghz without a higher voltage which my aio can't cool. My motherboard is a msi z390 gaming edge ac and my aio is an ek 360 basic. I am very new to overclocking so I don't know what I am really doing I watched a few videos but nothing really worked to reach 5.0ghz.
 
not all 9900k are made the same. some are just hot hot hot, and needs to be delidded

1) Are your AIO fans and pump set to max when you're running all cores at 100%?
2) Have you adjusted any other voltages?
3) Have you gotten 5.0 stable at any voltage? If not, what have you tried higher than 1.34?

I'm running a push/pull H80i GT 120mm AIO and it can cool my 9900KF @ 5.0/1.35v just fine, as long as I have all my case fans running full speed when it sits at full load for any long period of time. I think you may have more headroom than you think with that AIO.
 
9900k under any bench at 100% load is like hot hot hot especially once you go north of 1.300volts.

mine does 5ghz at like 1.330v but I cant stress test it for long as it just bangs into 100c Limiter. Gaming is fine at 5ghz but I would not render or do encoding at those volts and speeds.

also under a 360mm AIO and still runs blazzing hot.

Sand the ihs flat and try again do your AIOs cold plate too for even better results.
You can drain and clean out and refill that aio while youre at it, 70% distilled to 30% antifreeze you can increase the AF ratio by 5% for little to no thermal penalty and leave a small small bubble of air in the aio for thermal expansion of the liquid or you can expand the loop with an additional cheap alu radiator(s) and reservoir off ebay. (new rads are like 20-30 bux depending on their size and an acrylic cube res is 15)

You've got quite a few options.

I'm curious what power supply and GPU you have in that mix.
 
9900k runs really hot at 5Ghz. I was having trouble cooling it with an NHD15 at ~90-92c but with the current 420mm I don't break 80-82c depending on ambient, under AVX loads, ~200W package.

Try using some looser LLC setting, the middle one is best. Vdroop is your friend and a high idle voltage doesn't hurt the CPU. Mine idles at 1.44v but under load it goes down to 1.2-1.22v VROUT and is fully stable.

My aio fans run at 100 percent when the cpu hits around 80c. I have the llc set to 6 and other than vcore I have not changed any other voltage they are all set to auto. I did get a stable 5.0 ghz at 1.36 volts but according to intel extreme tuning utility it thermal throttled 2% of the time while cinebench was running and I was able to play r6 on high settings and the cpu package peaked at 76C.
 
Not uncommon. Silicon lottery no longer exists as a company, but their binning stats on the 9900k are still there. Only 30% of 9900k's produced can achieve 5.0GHz. I wouldn't be too upset.

That was one of the reasons I purchased the 9900ks, the other was a flash deal.
With 9900ks it was just plug and dial 5ghz all cores, even with noctua air cooling I could run 5ghz cinebench and realbench.

The big problem with 9900k was the increased silicon height barrier Intel introduced for soldering witch was just fixed properly on 12 gen.

The only way 9900k can stay sane is either some better cooling or a very binned chip with lower voltages.

Indeed. Both of my 9900K's are delidded and have direct die cooling from NudeCNC. One of them can do 5.3GHz and the other can't get past 5.0GHz. The both run very cool.

I'm really curious, what kind of temps are you getting with direct die? What cooling are you using?

TBH, I haven't done thermal testing on my 9900k's in a bit. I did do a brief ADIA64 stress on the one in the office that you can check out HERE. But to be fair, that system is SFF and has one UT60 radiator in it with the 9900k and a 3070. I do have to run fan RPMs a bit high. I would usually never run that configuration, but I had to get that build done.

The waterblock I use can be found HERE. I have had many conversations with Erik and he stands by his product. Quite frankly it is the best waterblock you can slap on top of a 9900k period.

I do have my secondary 9900k setup off of a 1080 downstairs and could run some benches if you like. I am pretty sure she can bench around 5.1-5.2 GHz.

Alright so with a 16c ambient you're getting a max Core temp of 58c. I just did a quick AIDA CPU test and got a max Core temp of 73c, with a 26c ambient, so adjusting for the 10c ambient difference, I would be at about 5c difference compared to a delid 5Ghz 9900k on a custom loop. Interesting. Well, I'm quite happy with my results then! :D
Thank you for your reply!

Of course. Dont forget, its on 1x360. That test ran for an hour and a half too. I would be happy with your results too. ☺
