You're questioning whether 3000MHz is sufficient. It sounds like you're concerned about performance or compatibility. Let me know if you'd like to explore alternatives!
The CCX communication bus runs at the same speed as the RAM frequency. Higher RAM speeds mean faster communication. DDR4-3000 works but performs best around DDR4-3600 to DDR4-3800. For top performance, consider DDR4-3600 CL18 or DDR4-3800 CL16 (if you can get them). If DDR4-3000 is the only option, it should still function well. It will definitely outperform the i7-9700 with DDR4-2133 memory.
Supported is JEDEC standard. Generally the maximum performance without XMP is achieved. Most devices offer a JEDEC speed rating of 2133 or higher, though some reach 2666. There are also JEDEC-rated units with a 3200 rating.
13600k can handle 5600MT using DDR5. If it fails at XMP settings, the issue likely lies with the motherboard or the RAM installation.
