Consider this setup carefully. The combination of the i3-10100f and Gigabyte H410M SH2 works, but it depends on your system specs. The 3000MHz RAM is a solid choice, though you might want to verify your motherboard and CPU support for speeds up to 2666MHz. If your hardware only goes up to 2666MHz, the 3000MHz option could be better. If you're open to upgrading later, the 2666MHz sticks are still viable. Choose based on what you can actually install and future-proof your build.
Higher MHz are preferable, lower CL is ideal. CL refers to CAS Latency. Aim for minimal delay. A 3000MHz CL16 performs significantly better than a 2666MHz CL19. Choose the 3000MHz option even if your board only supports 2666MHz.
Note that higher MHz is preferable when comparing CL, lower is better. This applies as long as all RAMs share the same MHz. For instance:
Case 1: RAM-1 = 3000 MHz CL = 19
RAM-2 = 3000 MHz CL = 18 → choose RAM-2
Case 2: RAM-1 = 3600 MHz CL = 19
RAM-2 = 3000 MHz CL = 16 → choose RAM-1 because higher frequency wins
oh, thank you very much. So Ram speed is way more important than the CAS Latency? Is it true tho that my motherboard only supports 2666Mhz and that a faster Ram Speed wouldnt make a different? And also, do i have to clock the Ram stick down manually or can i just put it in and it will work just fine?
It should start at the standard 2133Mhz, and you might need to adjust it yourself (or try XMP).
