ECC UDIMMs.
My UDIMMs have on-die ECC. What is the difference between that and an AM5 BIOS setting of "ECC"? Is it preferable to disable it in BIOS and let the on-die ECC do the error correcting instead?

Played a game with them on same core and it felt worse, pc felt more unresponsive in general so I switched back and now it feels better.
sometimes i get delta 1990-2010hz on usb controller. im need restart usb controller 1-10 times to fix it to 1999-2001hz. i cant explain that, but it cause on clear install.

This is a common misconception due to incorrect marketing from DRAM vendors. What I was referring to is
side-band ECC
Take a look at these articles:
MemTest86 - ECC overview
Intel — Everything You Need to Know About. Error Correcting Code (ECC) Memory. The difference between ECC and built-in data checking.
How often do ECC errors occur?
ECC vs non-ECC differences for server performance
Somewhat of a tl;dr:
Scenarios where you're protected:
1) “On-die” ECC, “non-ecc” UDIMMs
Transit =>
no
Rest =>
yes
2) “SIde-band” ECC UDIMMs:
Transit =>
yes
Rest =>
yes&yes (more protection)
Hope this helps.
