Z390 with I7-9700K, issue
shadowsports:
Greetings,
Still nothing conclusive.
What are you other system specs?
PSU is?
Case is?
What are you using for cooling?
What do you have connected and where exactly?
Do you have any fan controllers, etc connected to the MB in the case?
I would continue to bench test, MB out of the case.
I suggest you go back to F10, (use QFlash), then perform an additional CLR_CMOS) stick with the 9700K for testing and use QVL RAM certified for your board.
Your experiencing too many individual issues which all appear to be related to component instability.
Testing or running a base install without QVL RAM can cause all sorts of issues. Might work, might not.
Your coil whine is likely caused by your GPU. If one is not present, then your choice of PSU (maybe).
I have found the VRM and voltage on the Z390 to be fairly stable. Note, I do not OC as there have been some reports of VRM instability as OC demands increase. F10 and F11 did improve VRM performance (tolerances). Boards with earlier BIOS revs exhibited the most VRM variance, but again only in situations where above average overclocking was attempted.
Using a case with good static pressure is important for heat dissipation.
I fear you will be forever chasing elusive behavior. You have zero consistency since the first 6 months of ownership and and all attempts to rectify have been more like band-aids.
Why did your supplier replace your first CPU? Is it possible something was damaged? You also said they "repaired" the board. By doing what? Only Gigabyte or an authorized repair facility can safely service or repair a motherboard. If your supplier made some kind of non-factory "repair' you may never be able to get the system to run properly.
Even when done carefully, swapping your CPU can result in problems. Misalignment, bent PINs, etc.
I know this is a massive amount information to process, but you have so many unknowns it difficult to isolate behavior which can have more than one cause.

Hi
My setup is:
Motherboard: Gigabyte Z390 Aorus Pro (Rev 1.0)
CPU: Intel Core-i7 9700k
Memory: Kingstone HyperX Predator HX432C16PV3AK2/16
PSU: Corsair RM750X CP-9020179-EU
VGA: PowerColor Radeon RX 5700 XT
Cooler: BeQuiet Drak Rock Pro 4
SSD: Corsair MP 510 CSSD-F480GBMP510I
The case is Zalman K1 with 6x120mm fans
Do you have any fan controllers, etc connected to the MB in the case?
No fan controller was attached to the motherborad, in fact I did not connect anything to it just power,reset and hdd cables of the case.
No GPU, no extra hdd, just the boot m.2 device. I cleared the CMOS numerous times(with pins and also by removing the battery)
I haven't done any OC, evething(settings) was out-of-the-box.
Why did your supplier replace your first CPU? Is it possible something was damaged?
You also said they "repaired" the board. By doing what?
Unfortunately I bought them from a webshop, so I can't contact the service myself and even tho I asked the webshop, they could not provide me with the information as to what was repaired on my MB, and I also don't know the reason why did they replaced my CPU.
I checked the CPU socket as good as my eyes let me, no sign of any physical damage. And my other CPU (Pentium G5400) can boot and work 100% of the start-ups
BTW why is there a dual-BIOS sytem on the mobo? I didn't find any method for switching between them. I see no point.
And thank you for your help so far!

Greetings,
Thanks for the additional information and compliment, but I've done little at this point to actually help.
Using the following, try setting the memory values for your RAM manually in M.I.T.
Intel® Extreme Memory Profiles (Intel® XMP) 2.0. Total capacity is
16GB. Each module has been tested to run at DDR4-3200 at a
low latency timing of 16-18-18 at 1.35V
Z390 Manual, refer to page 27+ for memory settings:
https://download.gigabyte.com/FileList/Manual/mb_manual_z390-aorus-pro_wifi_1001_190708_e.pdf
See this page for additional Translation, module number decoder. (also) Latency timing is located near the bottom.
https://www.hyperxgaming.com/unitedstates/us/decoder
The CPU's default is:
DDR4-2666
The RAM looks like it will run at or close to 3200Mhz
Good Luck!

Hi
Sorry for the late reply.
I actually realised that I made a typo with the memory type, it's actually PB instead of PV, so HX432C16PB3AK2/16 and it's on the QVL.
I haven't tried the XMP yet, because at first it was working with the out of the box settings, maybe I will give it a go.
By the way have you diabled the C-States in your BIOS?
I read that it can fix the coil whining for me.
I'm planning to buy a new MOBO while I battle with the supplier. Do you have any suggestion for a brand and type in this price range? I checked out a few models similar to this (Asus boards have inferior VRM, MSI boards were not recommended at all etc.) This board has the best hardware specs by far but the Gigabyte BIOS/support is a little bit underwhelming so I'm a litte bit hesitant to buy the same product. Any thoughts on that?
P. s. Merry Christmas

Happy Holidays,
I tend to stick with what works and am fairly brand loyal. I used Asus exclusively for over 12 yrs. After owning, building and upgrading a countless number of systems, I had a BIOS flashing failure that resulted in a bricked board. Although I had a back up, was connected to a UPS, was flashing at the BIOS level and received a "successful" message, the board was left bricked and unrecoverable. After research, I found the issue was the result of a flawed process. Not something I had done incorrectly. Asus "Crashfree" BIOS and boot block recovery both failed as well. So their single BIOS promises were nothing more than marketing hype. I contacted support fully expecting them to do the right thing. Replace the BIOS chip. Simple 8 pin IC, pop out and pop back in. I got the run around, and that's when I realized Asus was full of "you know what". I ordered the chip myself and 7 days later the entire experience was a unpleasant memory. However, that $30 decision on their part cost them all of my future business. I walked away.
Moved on to Gigabyte and never looked back. No regrets either. The fact is, all hardware fails and any manufacturer can have product issues. How they choose to support their customers and rectify problems is what defines them and builds reputation amongst the user community.
If it were me. I'd stick with Gigabyte. They use high quality components, have exceptional manufacturing and attention to detail. I think the Pro/WiFi board is worth the additional cost. Its about $20 and even if you never screw on the Wi-Fi antennas the Bluetooth is a nice to have option. My Z390s are both solid, and have been very stable performers. I recently added new audio using the optical out and the sound quality is great. I'm not going to tell someone not to buy another brand if that's what they want to do.
My preferences:
For Motherboards: Gigabyte
CPU: Intel
Memory: Corsair or GSkill
GPU: EVGA
PSU: Corsair or EVGA
Storage: Samsung
