I have 2 memory sticks (2 x 16 GB): Lexar 32GB (2x16GB) 6000MHz CL30 Ares RGB (M-Die)

I really want to increase smoothness of my games because I get a headache seeing any microstutters.

Currently using Ryzen 7 9800X3D (-20 two best cores (-25 was unstable) and -25 rest of them) it might be pushed beyond that, but I have no idea how to make this process less sluggish with CoreCycler (so getting better per-core negative CO).

These timings and voltages were mostly taken from the Buildzoid (Actually Hardcore Overclocking Youtube Channel) easy Hynix 7000 series.

I tried FCLK 2200 and it was stable with VT3 Y-Crucher test, however after a month the test speeds do vary even with the auto 2000 MHz (but only with default memory test setting, when I changed it to 10 GB it was very good), I don't know if it was a thermal issue, so I think an additional fan may be needed. And I might be delusional but I think that my browser scrolling stutters more with fclk over 2000? (might be coincidence as well).

What can I potentially improve? Tested tRFC 450 and lower and my PC had booting issues.

My AGESA is still 1.2.7.0 (not the latest 1.3.0.0a, because it's still a beta BIOS for this motherboard).

I'm not an absolute enthusiast of RAM overclocking, so I have insufficient knowledge about it.

Thank you in advance!
