stressapptest VS bitcracker

That's super old and not very useful anymore. Use Google's stressapptest Might also be worth booting Windows for TM5 or HCI Memtest.

I've personally used stressapptest a lot ( https://github.com/stressapptest/stressapptest ), it's not perfect but it's easy to use from a linux CLI. If that can run for a whole day without spitting out errors then it's probably not the RAM

You're running linux? You should try GSAT for validating memory OC stability and stress testing.

For what it's worth, this was one of the semi-popular "new" memory testing tools doing the rounds back when Ryzen was new: https://github.com/stressapptest/stressapptest

You need to run some memory stress test to verify that, like google's stressapptest (runs in Linux only)

It's not guaranteed that 2 kits will work together, but given the total dearth of 4-DIMM kits on the market, that's probably what you'll have to do. Give it a good overnight burn-in test with prime95 large FFTs, and maybe Google stressapptest, especially if you enable XMP.

If trying to repair the windows install does shit the bed, one debug step you could try would be making a bootable linux usb to see whether that exhibits the same crash behavior. It could pull a bit of double-duty if you run a memory-focused stress tester like: https://github.com/stressapptest/stressapptest to see if it throws up any errors. If you go with a semi-recent Ubuntu release, that one is already in the official software repositories and thus easy to install.

Prime95, Intel Linpack or Linpack Xtreme, y-cruncher, GSAT, Blender 3D rendering, Linux kernel compilation works very well too.

I'd recommend the (former) Google stressapptest: https://github.com/stressapptest/stressapptest

Clean reinstall. Or try bitcracker : https://github.com/e-ago/bitcracker

This is correct, you can bypass Bitlocker if it uses a password instead of or in addition to the 48-digit encryption key. You're looking for this: https://github.com/e-ago/bitcracker unless there's a newer version. This is what I've used in the past.

but yeah, as the others have said you can definitely mount a windows drive on linux. I prefer using gparted cause you can visualize the partitions, but testdisk and photorec can also provide insights into the partition sizes and can do full data recovery on the non-encrypted partitions. This also looks pretty promising, but from my experience, you'll probably have to set up a dedicated machine up for running it... I'm guessing about 7-8 weeks to run it on, also guessing it's about 128gb drive / iso: https://github.com/e-ago/bitcracker These are just guess on the performance though, that I'm basing on previous experiments from scrubbing drives in the past...

So I decided to buy it, since I think 30 bucks is a fair price, even though it might just be a fancy wrapper for the open source bitcracker (I can't be bothered to create my own dictionary files and BitLocker Password is really easy with this).

You could try BitCracker (https://github.com/e-ago/bitcracker) - it is a brute force password attack tool (open source).
