So, I recently made an upgrade on my PC and went from AM4 to AM5
I bought an
Motherboard: ASROCK B650 PG RIPTIDE, AMD, MICRO ATX
CPU: Ryzen 7 7700
RAM: CORSAIR VENGEANCE 32GB (2X 16) 6000Mhz CL36
I don't have much knowledge about this but studied a little bit about
First is before any optimization ( don't have after)
Speed 4800 MT/s
Clock at 2400mhz
tCL 40
Tried to set speed to 6000MT/s
Clock at 3000mhz
tCL tried to gradually reduce
36 was ok
34 my PC didn't turned on
I went back to 36
One more point, before optimization that green line, the frametime
It was stable, no waves
Now it has little waves like in the picture
The problem is, before this it was stuttering some games like Ready or Not with frametime stable
Now it's not with frametime like that waving
Can I reduce my tCL more than what is specified in the RAM itself
What about frequency, maximum is 6000mhz, can it go up more?
Is this little waves a bad adjustment?
Can I reduce other values?
Can someone help me, with a better adjustment or how to adjust it
I apologize for wrong words, using a translator

This would be a good start and watch couple of his videos explaining everything.
tCL as a timing doesn’t really matter for performance. The video linked by the other commenter has a great, detailed breakdown of what timings to set.
Make sure the sticks are in slots 2+4, then enable EXPO. Just setting frequency + CL by itself is not the correct approach.
Stability test just EXPO before attempting manual tuning. Use a program like testmem5 on the absolut config.

Maximum frequency depends on your CPU. UCLK is the limiting factor, which scales with SOC voltage. You want 1:1 ratio of UCLK:MCLK and 1.30 VSOC or less for daily use.
Run FCLK at 2:3 ratio, unless you can achieve 100MHz higher. The extra bandwidth would be worth the latency disadvantage.
Frame time variance is normal, games are not consistently demanding. The important thing is maximum frame times, you want games to feel smooth. Most reviewers will display this as 1% and .1% FPS numbers.
