Good people, please help! Faced with a serious problem and what I just did not try, the story begins with the fact that I built and bought a new computer, 2 months ago, but the hard disk and SSD inserted the old ones, and all the other components are brand new, once I accidentally deleted the Windows folder on disk C and I have a desktop it became empty, I restored it from the trash right away and everything came back, everything was fine, nothing foreshadowed trouble. Then I went into the game, for the first time I crashed on the desktop without an error, I thought okay, sometimes after a couple of hours, not earlier, maybe even more than two hours, it happened again, then I started to worry, but I thought something with the game, the game was Rust. As a result, I tried to go to another game, Dota 2, in the end, everything is the same, only much more often, crashes to the desktop without an error every 10-20 minutes, in the end, I decided to pause the games for now, but it wasn't there! I also started to crash in browsers, and much more often, every 5-10 minutes, sometimes I'm lucky and every 20-30 minutes, it happens every minute or every minute 5 times, and this is in any browser, but in a couple of browsers it gives errors that I will attach, in the end, after all these misunderstandings, I freaked out and decided buy a new memory, I thought it was a problem in Windows, but I had 10 Pro. I bought a new memory, 2 SSD M2, which I mentioned above in the configuration, put a clean, licensed Windows 11 Pro, installed the latest drivers, but what was my surprise when I went to the browser and the same problem continued, it did not disappear! In games, similarly, nothing was solved, then I went to the Microsoft forum in search of similar problems-topics, found a dozen, reread them all and tried everything that was recommended there, nothing helped me, tried all the commands on the command line to restore and search for damaged Windows files, tried to turn off autorun in libraries everywhere, I tried to reinstall the drivers and install earlier versions, tried to delete and re-download the Xbox, all without any problems, the XMP mod turned off, although when I turned it on, and this was immediately after I built the computer, there was nothing like this for a month and a half, until the whole story began as I wrote above. Tell me what else you can try... all components are brand new, can not be damaged, please, people, help! The computer is the breadwinner of my family, I don't know what to do already... in my village, there are not enough Service centers for such a powerful computer
1. Everything is connected correctly, nothing is loose, rechecked 3 times, all components.
2. I tried reinstalling games and browsers, nothing helps.
3. Overclocking was enabled, XMP mode, I turned it off, did not help.
4. Updated the BIOS to the newest version, but this also did not solve the problem.
5. I checked the power supply, everything is fine with it.
6. When reinstalling Windows and so a new account was created, it did not help
Also, in parallel to what you recommended to do, I made a computer diagnostic, namely my RAM, there are no errors, there are no defects in my components

With Dual Rank memory it might be difficult to run this above 6400 MHz. Everything depends on CPU IMC (Memory Controller).

Also, you need to be careful about temperatures, so extra fan over ram sticks might be required to either run this with higher frequencies than 6400MHz or tuning the timings.

I understand, can you advise me on RAM? Under my motherboard, a friend threw the site off to me from above, but my brain is already exploding, I can't figure out if I can take 4 pieces of RAM, and not 2, what's better in general? and as I understand it, it makes no sense for me to take more than 6400 mhz, since the site indicates that this is the maximum

You did not write the most important thing (as an example (F5-6400J3239G32GX2-TZ5RS)). Is your choice on the tested list? Have you looked at the list at my link?
When I chose memory for myself, I bought such a 32Gb DDR5 6400MHz G.Skill Trident Z5 RGB (F5-6400J3239G16GX2-TZ5RK) (2x16Gb KIT). I took two such sets. It is among those tested on the Asus website and everything works great.

Here's the screen

Copy the memory model in the price of the store and paste it into the search bar called Ctrl + F, and if there is such a position, it will be highlighted in color.

Yes my friend, 

I finally understood, I just don't know English well, in general, I found TRIDENT Z5 RGB 64GB 6400MHz CL32 in my city 

F5-6400J3239G32GX2-TZ5RK, which is on the list just. I'll take these two 32 GB dice, but I have an additional question, should I take 4? In terms of performance, won't there be problems?

[dennys2009]

It seems to me that 64 GB is enough for everything that you would not do and the 6400 frequency is enough even for the next Z890 platform. The backlight was still important to me. When 4 modules shine, it is more beautiful than two.
