I wouldn't hesitate to give up for APUs, as @freeagent and @ShrimpBrime would likely have deeper insights into clocks and timing. There are some wild experiments happening at 4400 or 4800 with the 5600G, but there aren't many solid videos showing it pushed to its limits. I'd probably have to check out Buildzoid's channel for more details.
The Infinity Fabric seems to be the main constraint in my view. AMD tends to clash with Hynix often. More RAM definitely reduces high-speed potential. It's a risky trade-off. To offset the performance drop, you can recover up to 4267mt/s and beyond. 32GB works, @freeagent has plenty of cases and guidance, though I only use 16GB because I don’t stream or anything similar.
I'm using a 2x16GB G.skill Ripjaws V 3600MHz CL16 setup with my 5900X. The cards are dual-rank, and I've boosted the RAM to 3800MHz and the FLCK to 1900MHz. Results are excellent.
For high-speed clocks or configurations tighter than C14, such as C12, I run my Royals. The B+W kit I have matched doesn’t perform as well in terms of capacity and flexibility compared to my Royals, and it requires a bit more power. This is my first DDR4 installation. I’ve been using DDR3 until the end of last November. When I discuss topics beyond what I understand, I mean my current configuration—since those are the only details I’m familiar with. The only way I can measure progress is through HWBOT. My results aren’t top-notch, but they’re not terrible either. And with the upcoming cold weather, I’m hoping to recover some of my previous performance.
