[Noob] i9-9900K overclocking

I am new here. Not only here but to overclocking in general. Well, actually PCs in general. I have been using macs for a long time. However, here I am with a shiny new computer. I am a scientist doing simulations, so the horsepower is somewhat important. Since I am very new to the scene, I thought I would try and test the CPU in standard mode.

This is my setup: NZXT H200 - AsRock Z390 Phantom Gaming-ITX/ac - Realtek ALC1220 - Intel Core i9 9900K - Kraken X52 - 32 GB (4x8 GB) 2666 Corsair Vengence - Powercolor Radeon Vega 64 8Gb

The first thing I tried running it no OC whatsoever. I am using AIDA64 to test for stability / temperatures and I record the data with HWinfo64. These are my results after approx. 15 min.

min mean max standard dev.
Core #0 [°C] 67 78.752 88 5.172283
Core #1 [°C] 63 77.392 89 5.477072
Core #2 [°C] 71 81.928 93 5.810413
Core #3 [°C] 68 81.312 93 5.366287
Core #4 [°C] 69 81.688 96 6.064726
Core #5 [°C] 68 79.264 89 5.377888
Core #6 [°C] 65 76.808 89 5.794458
Core #7 [°C] 67 77.992 90 5.574273

all cores ran at 4700MHz with a mean Vcore of 1.266 V.

Here is my question, is this normal? Temperatures seem to fluctuate pretty strongly and what I have read so far, a mean temp around 80 is pretty high, no? I am looking forward to some input on how to continue. Attached a plot of the temps.

Cheers

How are you reading vCore? Should be looking at your VR VOUT sensor on your AsRock board. My vCore sensor on my Taichi reads way higher than what I'm actually getting.

Yes, core to core differences are normal. Yours are fine. ~80c under a synthetic load on an AIO isn't really high either with a 9900K.

hey, thanks for the reply. Glad that the differences and temperatures are normal. I am getting the vCore from HWinfo64. I guess that is wrong? Where can I find the VR VOUT? Sorry if this is obvious, but I don't know.

You should have a VR VOUT sensor somewhere in HWInfo. AFAIK the vCore reading being inaccurate and the VR VOUT sensor being accurate is limited to Asus and AsRock boards but don't quote me on that.

Mine reads a ton more voltage than that it's actually getting, ~1.4v when I'm really only ~1.32v.

*edit:* only reason I bring it up is because you likely can drop it. ~1.27v for 4.7 seems a bit high, I was getting ~1.2v out of the box on my 9900K.

It's in HWInfo64, you just have to look for it. It's labeled "VR VOUT". I don't know which section its in by default (perhaps about 2/3 of the way down if I recall) because I've rearranged my rows.

Hey, thank you, guys. I will check when I get home. The data I showed earlier was stock settings. Yesterday, I played around a little. I set it to 5 GHz all cores and 1.280V (vCore not VR VOUT). Running Cinebench and Aida64 (10 min) seemed stable with a temperature in the 80-90C. Going lower with the Vcore on the BIOS crashed Cinebench. I tried to sort of a top-down approach, started at 1.3V and worked my way down. Is this the right way to do it? I will check what "VR VOUT" reads for this, but the vcore is at least close to what I set it to, even though that might not mean much.
I was a bit surprised, that Aida64 runs not much hotter. However, I did disable AVX. I read somewhere that you shouldn't use that and I have set "AVX limit" (or something like that) to 4, so the CPU would only go to 4.6 GHz. Is that correct or not the way to do it?
Cheers

So I have checked HW info, but I can't find "VR VOUT". It is not hidden, either. Is it possible that my board doesn't have that sensor?

Your board does not have VR VOUT sensor.
