Weird Instability issue

[ivaylo.st]

Hey guys - I've been having this issue on my PC essentially since I built it in February, but it's finally annoyed me enough to try and troubleshoot it.
For some reason, specifically Chromium-based apps have been either crashing, or having a black screen. Let me elaborate -
for example, I'll be casually browsing on Chrome and it will crash out of nowhere, or I'll be in a game, and when I tab to Discord, it's gonna be a black window or frozen and I'll have to exit and open Discord again, but voice chat and everything will keep working while it's frozen.
I also have the odd game crash on Cyberpunk or a freeze on Spider-Man: Miles Morales, but it's something that occurs rarely.
I have this weird feeling that I'm having a memory issue. I don't know if I'm not setting up memory right in my BIOS or something, but in both Windows and CachyOS which I'm dualbooting right now, but mostly using CachyOS, both report 6000MT/s. 
For instance, I'm running these specs:
MSI B650-M Gaming Plus WiFi motherboard;
Ryzen 5 7600, completely stock, no overclocks or undervolting;
Corsair Vengeance 32GB (2x16GB) 6000MT/s @ CL30; XMP ready only, not EXPO, which could maybe be the issue? I'm not knowledgeable on memory standards.
Used RTX 3070;
Seasonic GX-750 PSU.

I'm running CachyOS for about 3 weeks now after I moved from Windows 11 and it's been serving me great aside of the issues I noted that were very much a thing on Windows as well.
Please give me tips on how to go forward with this! Thanks beforehand!

PS: Ran a 2-pass MEMTEST86. No errors reported.

Update the bios if you haven't already done so.

Then if it still give memory problems try lowering the speed until it's stable.

Have you done a memtest?

 

Another thing could be the Nvidia drivers, which can cause problems for some still. Do you have the latest 580.88? If not then update.

If you already have that version try the 566.36 instead.

Also don't install the Nvidia app, install only the drivers.

 

Other things you can check for, if there are any suspicious errors/warnings in the Event viewer, and if there are any warnings in the Device manager.

 

You can also check the health of Windows by doing the DISM and SFC commands.

And install an app that you can check the SMART info on the drives, like CrystalDiskInfo.

Gonna do a memtest and update this post. Pretty sure the bios is up to date, as for the other stuff, I'm not really using Windows regularly anymore and all of my drivers are up to date on both CachyOS and Windows, but if it comes to it I'll try on Windows.

Okay - ran a 2 pass memtest86. Weirdly enough, zero errors. I'm a bit confused now. Maybe a GPU problem?

Try lowering the speed of the RAM aswell, then test if those apps and games crash.

 

If that doesn't help then it could be the Nvidia drivers.

Guess I'm gonna try 5600mhz later. Will reply and see if things are better. Weird though as 6000MHz should be stable..

BIG UPDATE

Turns out, months back when I was setting up memory on my system, instead of turning A-XMP in the MSI BIOS interface, I turned on a stupid setting called "Memory Try It !" that on first glance looked like the right timings and stuff, but in reality only the 30-36-36-76 was right and all the rest of them were wrong. Makes sense why after I turned that off, turned on A-XMP and it automatically picked up my memory's correct profile and now not only is my system running smoothly, but it doesn't have to retrain every boot, because before, if I kept the BIOS setting "Keep Memory Context" or something along those lines enabled, my system would just crash on boot. Now, because my timings are correct and the setting is enabled, not only is everything working, but my system is booting like 3x faster.
Moral of the story? RTFM.

another small update, now most games i'm running are like 30-40fps over what they were previously and cyberpunk loads into my save for less than a second vs like 5 secs before
