Overclocking 9900k on z390 Aorus Master

[Asryan]

I have ordered thermal paste I don't have any more to test but for what I know the difference between a perfectly applied thermal paste and a bad one can"'t be a 10c difference in thermals..

For the peak temps, i saw it reach 70 max

LOL, it sure can be!

70C max gaming......... I'd expect that to be a bit lower... but, you are in the ballpark, really.

 

[Asryan]

ballpark? what does that mean?

70c is quite rare usually i'm more into 60 to 65 but on the most cpu intensive game it's about 70 peaks

On red dead 2 for instance, CPU package maxed at 63

Agree with ED. And it isn't just about how the thermal paste is applied, it's also about how the water block is fastened.

So just to cover both bases, after cleaning the top of the CPU and he bottom of the water block with alcohol, put a small blob in the center of the CPU face. Somewhat larger than a BB but smaller than a green pea. Don't try to spread it. Lower the water block evenly/level onto the CPU and keep pressure with your fingers on it to not let it move around or disengage. While holding it down, begin to tighten the pressure nuts in a "X" pattern back and forth, one or two turns on each at a time to get even pressure until they bottom out.

And as ED said, 70c is not an excessive temp while gaming when running a 9900k. Not sure what you were expecting but throttling on those chips doesn't start occurring until you reach 100c.

Is this system ever used for intense computing? (i.e. heavy, long duration rendering, mining/folding, handbrake)

If this is primarily a gaming, surfing, and Youtube rig your temps are fine. You will never hit the stresstest temp in games. Even heavy, high stress games should only max the CPU like a stress test for short bursts. My recommendation is to enjoy your rig. When you get a new game, watch your temps and see if you have issues then. Otherwise just enjoy.

"ballpark" means within an acceptable range. It's an American idiom from the game of baseball. It's when a batter hits the ball such that it lands inside the boundaries of the playing field it's "in the ballpark".

Edited.

For cleaning, I have those : https://www.ldlc.com/fiche/PB00052590.html Are they fine?

And sorry but "BB"? English isn't my native language

Ahah ok thanks for ballpark

@ Blaylock i do some LIGHT video encoding on a software not as fare as heavy as adobe one, got around 60c on it not more.
I was just annoyed when i read that those temps were not normal at all but there are only few games on which i get a bit higher temps but never above 70c.


Also, should i try tweaking something in the bios like trying to lower LLC and rising vcore? I read that turbo Llc can impact temps at loads.?

 

[Blaylock]

You can tweak it all day and you might get slightly lower temps but my point is you are 30° from the max rated temp for that CPU. You have a long ways to go before you need to be concerned. Enjoy your games and your respectable overclock, and when you feel like playing around with you clocks, go for it. That's the beauty of overclocking.

Thanks! I was jusr concerned by all the alarming comments i saw

BB=sperical ammunition used in a pneumatic riffle or pistol. So we're talking about a blob of thermal paste approximately 3-4 cm mm in diameter.

And the Arctic Silver cleaning solutions you list would be fine. Isopropyl alcohol, aka, "rubbing" alcohol, would be a lot cheaper and just as good, however.

That's a GIGANTIC blob...I'm sure you meant 3-4mm.

by all the alarming comments i saw

Where? Other sites?

93C you saw when stress testing is OK... where are concern lay is that the test is without AVX. So anything that may use AVX could spike temperatures higher. But if nothing you are doing uses that, then I wouldn't worry about it...or set an offset for AVX.

 

[trents]

LOL! You posted before I could change that. I realized my mistake but when I went to change it you had already posted. You're quick on the draw, ED. If OP had followed my original instructions it would have gotten expensive for him.

I've ran an OCCT small without avx last week and even if temps were high, it passed it during more than 3H.

Yesterday, while playing a game (desperados 3), i've noticed some WHEA errors in HWINFO.

I tried an avx offset and saw that this game was indeed using it but even with avx offset, still errors but ALSO BSOD.

I decided to run the same test I did last week but the small occt freeze my PC and gives different BSOD : Whea uncorrectable error / irq less equal something.

I even tried with higher vcore, 1.28, same thing !

I really don't understand what's happening



managed to pass prime small no avx 1.33, high llc instead of turbo with those results, 2h30 run

intel has set proper VID for all cores up to 5ghz for these cpus. Prior to 9900k I never used auto for vcore. But you can set vcore to auto, cpu multi to 50 like you have it, and you can at least see VID intel set for 5ghz, and run occt small (with avx) for 10 seconds and watch vrout needed for stability.

Your vrout min is 1.203 which is most accurate vcore your chip is getting at that high amp/resistance + vdroop when running small with avx..

My 9900k wont run 5ghz small fft with avx stable for even 1 second, unless I use auto vcore, which sets my vid to 1.43ish, and vcore 1.36 idle, and vcore 1.22min vrout running occt/small with avx. If I use high/turbo LLC to even keep vcore min at 1.34 (vcore set 1.38+) ....still will instant bsod, likely from not enough vdroop and wild transient dips with high amps. If I reduce VID by even .01 using vid neg offset from auto vcore, I get errors. Ie intel set auto vcore on mine just high enough to run OCCT/small stable, 1 notch below and errors. And if I negate vdroop at all, again errors.

but my cpu is pretty bad, im convinced it is one of the binned failures for 9900ks. 4.9ghz I dont have that issue with LLC running occt/small with avx, 5ghz is just on edge of stability with mine.

 

[Asryan]

Very weird but after formatting and reinstalling windows it's stable again.. I was suspecting that it was driver related because I had a irq less equal thingy bsod

1.26
Turbo LLC

Ran prime small non avx for almost 3h with those results

 

[EarthDog]

IRQ message can be anything...vcore instability even... glad it worked out!

 

[Asryan]

Yep i jusr had some kind of a hunch and temps are ok i guess
