Yes, you can combine two memory sets with varying speeds.
You're evaluating your current setup and thinking about a potential upgrade. It's understandable to feel uncertain about balancing performance gains against potential drawbacks. Upgrading from an i5 8500 to an i7 12700K is a significant jump, and your memory choice plays a role in overall speed. Mixing 8G sticks could provide a larger total capacity, but RAM speed matters more for tasks like gaming and design software than raw capacity. If you're mainly using your PC for gaming and occasional creative work, the difference might be minimal—perhaps only a slight improvement in frame rates or smoother performance. However, if you notice noticeable lag or reduced responsiveness, it could be worth considering selling the old sticks for better value. Ultimately, test upgrades in real conditions to see how they impact your experience.
It won’t significantly affect the FPS numbers. Just stick with one setting. When combining two RAM speeds, the system picks the lowest compatible speed—like 3000MHz for your CL15.
You can achieve this, though you must adjust the clock speed in BIOS accurately so everything operates together. Reducing RAM speed has minimal impact, but pushing a 3000MHz chip to 3600MHz may damage it.
