3600 CL14 offers impressive speed, making it a great choice unless you prefer adjusting memory timings for higher performance.
3600/3800 CL14 would be ideal, though you might save money without sacrificing much in real-world performance. In most situations, a 3600 CL16 setup is sufficient (CL18 also works well), and you could redirect the savings toward improved storage or a better power supply.
The 3200, 3600, 3800, 4000 and 4133 kits are probably destined for failure, which means they’ll perform optimally when you adjust timing settings. For simplicity, using XMP and skipping the rest will suffice; higher clock speeds need more work to align with FCLK and UCLK for stable operation, especially above 3600. This process took me several weeks to get the 3800MHz C16 RAM and 1900 uclk/fclk stable on my X570 Taichi/3900X, requiring fine-tuning of VDDG, VDDP, SoC, RAM and DRAM termination settings.
Looking ahead, the 1.35v kits may offer improved upgradability. Choosing between 32gb and 16gb depends on your needs. Running at 3200/3600 with the 3733 or 4000 kits at 14CL is still possible.
