Yes, it got rid of it completely.

Only thing that gets rid of it (for me) is to disable all c-states.

Does anybody have coil whine from Z390 Aorus Master while gaming and also while alt+tab from the game?

I have seen youtube videos and forums posts that talks about disabling C1 in bios to get rid of the coil whine. Well it did solve it for me but thats only for idle.

I thought first that maybe it was my Strix 2080 Ti that coil whined , so i did change it already 2 times and still have coil whine on my third gpu.
Today i tried my GTX 780 Ti from my old pc and the same coil happened on this also. In game and when i al+tab from the game.
My psu is Seasonic 1000W Prime Ultra Titanium (dont really think there is any coil whine from it).


The high pitched sound does really come from VRM part from what i can hear, and since i have the coil whine even when i alt+tab from the game i suspect it really is the moderboard that coil whines badly.



Does anybody have the same problem as me?

Is there any voltage settings for VRM in bios that i could try? Just to see if it helps somehow.

I am by no means an expert, there are many other people here with more experience to help you. But, I figured I would share with you what I've been learning over the last few days as I was in the same boat as you.

I have a feeling it will be very difficult to figure out what aspect of your overclock is causing you your issues.

What I had to do was roll back my settings and work through one thing at a time until it was stable. So I reset memory timings all back to auto, dropped the frequency and loosened the primary timings. Then from there I made sure the system as whole was stable. I ran OCCT Large/AVX2 for 90 minutes, followed my Karhu. Karhu made 18000% at that point. So now I knew my CPU was stable and my memory didn't have any flaws.

At that point I focused only on memory frequency. I set vdimm to 1.40 and SA/IO to 1.2 each and proceeded to bump up frequency until it showed issues booting and then actually chose to increase vdimm & SA/IO up to 1.45/1.25/1.25 and my frequency became stable. Then I ran OCCT Large/AVX2 and it crashed. Found I had to bump my vcore up a tad, so I did and re-ran. Then I could get through 90m OCCT Large/AVX2 and 18000% Karhu again.

Then after that I worked on primaries only. Dropping them, tediously, 1 each and doing the full suite of tests each time. Now my system has a safe, but stable o/c on it and I'm working on tightening it up further.

By doing it methodically you can very quickly and easily tell what is causing you issues. If you're just throwing in a "setup" that someone else has posted (not sure if that's what you're doing or not) and attempting to run it, you'll never know what the problem is.

Anyhow - just my two cents. It's possible there is somewhere here who may easily just point out what your issue is though, and then I'll feel like an idiot. lol.

Cheers!

lpittman During my last (and first) attempt at a memory o/c I went too quickly and although it was 'fast' it certainly wasn't stable.

So I started over and now the CPU is 90m OCCT Large/AVX2 & 4h WarZone stable and the memory is 9h Karhu stable on top of that, so I'm considering it to be stable enough for my use currently.

Wouldn't mind some input from some of you experienced guys at this point. Is there anything obviously wrong I need to fix? Any tips or suggestions are welcome.

Otherwise I'm just going to keep plugging away a little bit at a time.

Cheers! And hope everyone is healthy and happy!

MrTheSuperMario There is no issues with overclocking, but it was causing the intel management engine driver to not work. This got fixed with f11e. Maybe my hardware just did not support the firmware update from the wonderful bios of T1d and T0d he posted.

Great - thanks for the info!

vcore too low?
