I'm putting together a new PC this week and I've got all my parts ready. However, when I ordered my RAM, I didn't realize it wasn't officially supported by my CPU. Can I still make it work by downclocking the RAM to 6000MHz, lowering the voltage from 1.45V to 1.35V, and tightening the timings? I'm not very experienced with that kind of tuning. Is it possible to manage this, or should I just get a different RAM that works better?

Keep in mind that 7200MHz is technically an overclocked speed, so there's no guarantee your CPU will handle it that high without issues.
6000MHz RAM should be more than sufficient for your needs. Extra speed beyond that typically won't give you much more benefit.
Yes, you can downclock the RAM to avoid compatibility issues. It's a good idea to manually tweak the timings for better performance.
7200MHz isn't the best fit for the Ryzen 7800X3D—either go with 6000 MHz CL30 or push for 8000 MHz if you want to overclock. I’d recommend sticking with 6000MHz for stability.
You should be able to tune it down to around 6000 CL30 if your RAM uses Hynix chips. While 7200MHz can technically work, you'll be running in a 2:1 mode which might hurt performance compared to a native 6000 CL30 setup. Aiming for 6200 or 6400 CL28/26 is more optimal if it’s possible, but it can be a bit of a gamble with silicon quality.
Since it has Hynix chips, can I just copy timings from other RAM kits or do I have to start tuning everything from scratch?
