What RAM chips do I have with this kit?

I've found conflicting information concerning this kit and I'm having trouble figuring out what I've got. Since thaiphoon burner has been said to be inaccurate with DDR5 I haven't used it, don't know if this is still true.

I have it at 6000 with super tight secondary and tertiary timings (RAM OC takes a long time, and lots of tests to get truly stable but I enjoy it when I have time) with a 12600kf but I'm curious about safe voltages and what I should expect if/when trying to raise frequency, hence why I'm trying to identify the IC's.

Board is AsRock PG Velocita Z690, which overclocked my CPU great and RAM timings so far.

Everything runs fine, but if I can get 7200+ with looser timings and slightly higher voltage, that'd be cool.

What chips are on these sticks? Most say Hynix A die, but then others have said M, CJR, and then some say they're not even Hynix.. I just want a pro to finally educate me.

Thanks a lot.
