All good and nice in terms of functionality and features.. but... it has a strong coil whine (some coil? vibrating and making a continuous buzzing sound) that is not common at all!
I am trying to figure out what's going on and I learn that it happens in many motherboards (even in expensive models) and that THERE IS NO SOLUTION!!
Some have simply managed to reduce the sound intensity by deselecting settings in the BIOS. I haven't tried it because I find it unacceptable.
I must admit that I do not have the system enclosed in a case. Some have suggested as a last resort, the internal lining of the cases with those foam plates to limit sound.
Somewhere I read about using Celastic (it is that elastic glue they put around capacitors and transistors on power supply boards) but the problem is that I cannot pinpoint exactly the source of the sound, although, most likely it comes from a mosfet in the north VRM.

It's a shame, because it seems like a decent motherboard and completely VFM.
If I find a solution, I will come back.

Nice motherboard but it has issues. It refuses to accept the RAM at full overclock (6000 MHz) and also has some problems with the fans. Additionally, sometimes after a power outage, it takes about twenty minutes to train the memory. I would not recommend the ASRock or this specific motherboard. It's better to choose another brand, or if budget is a constraint, go for a good B650.

Bought a few days ago to do a complete system upgrade from Am4 to Am5. As soon as I saw that the price was 231 euros, I ordered it without a second thought. The installed BIOS version is 1.21, which is also stuck with a sticker on the motherboard. So I didn't update the BIOS even though it's not the latest version. Nevertheless, my system is very stable and it immediately recognized the RAM at 4800mhz and effortlessly read the XMP profile at 5600mhz cl36 Kingston Fury Beast 64gb. However, in previous unboxing videos that I watched from the first few days of release with the 1.01 BIOS version, they showed that inside the package you would find a large Gen5 heatsink with a fan for the Nvme Gen5 that you could install. However, in my case, it was not included, just like in others who bought this motherboard with an updated BIOS a few months later in 2022. This means that they did it to reduce costs. There were also complaints from many buyers that the sticker covering the RAM slots left adhesive and paper marks on the slots and was difficult to clean. However, in my motherboard, they had removed them and had done an update. So the box had been opened again at the factory. Now, as for the overall value of the motherboard, I will say that I came from an ASUS Prime B450M-A and the difference is huge. As a boot drive, I have a WD SN850x 1tb, which in the CrystalDiskMark test reached 7300+ read and 5900 write, and I also have a 980 Pro with a heatsink to store games. Both drives installed very easily, and from the 4 NVMe ports, one is Gen5x4 lanes to the CPU and has a very sturdy heatsink pre-installed. It also has a Gen4x4 lanes port on the chipset with a smaller heatsink that I didn't use. It also has a Gen3x4 lanes M.2 port to install an older generation drive, for example, from my previous system where I had a Samsung 970 Pro. Additionally, it has a strange Gen4x2 lanes M.2 port, which is paradoxical. Why did they cut 2 lanes? As for the thermal measurements on the VRMs in benchmarks that have been done, they never exceeded 63-64 degrees Celsius in the channels I saw on YouTube, so you can put even very powerful CPUs like the 7950X without a problem. I didn't explore the BIOS extensively, I only adjusted the fan speeds easily from there and the XMP profiles for the RAM. It also has some settings to automatically undervolt your processor without losing performance, so you can have better temperatures and better system health. I consider it a good choice not to go for the B650 but to prefer an X670, especially the Extreme version, which gives you the margin to have it for more years since it has Gen5x16 for the graphics card, so in future upgrades, there won't be any issues as we are still in the era of Gen4 PCIe graphics cards. It was the cheapest X670 I found and it had all the features I need
