The choice depends on your priorities. CL30 6000MHz offers higher speeds, while CL28 5600MHz is cheaper. Both are RipJaws, so compatibility should be similar. Consider your budget and performance needs before deciding.

DDR5 prioritizes speed, making clock speeds the main factor. The 6000 Cl30 kit is expected to outperform the 5600 CL28 in most cases. Even a slightly slower 6000 Cl40 would still edge out the 5600 CL28 thanks to minimal impact from CAS Latency. Theoretical CAS latency for both kits comes to just 10ns, so no significant difference exists. It’s mainly about getting the highest clocked configuration you can afford, with timing details being less critical. Those 5600 C28 models are unlikely to be viable, as they lack compatibility benefits and share the same chipset (Hynix M die) that consistently achieves 7000MT/s in overclocking scenarios.
