These two RAM configurations could work together.
These two RAM configurations could function together. They're very similar, differing only in frequency—5600MHz versus 6000MHz—and timing details match. Both are listed on the same site and use compatible components like the ASUS Prime X670E-PRO WiFi and Ryzen 7900X. Even though I usually avoid such setups, having 32GB of 5600MHz RAM in my system works fine, but the 6000MHz version is back in stock with a good Black Friday deal. Upgrading to 64GB would be a great option if it fits your needs.
Essentially they’re very similar except for speed units; the clock count (CL) is expressed in clock cycles. A CL36 running at 5600 MT/s isn’t the same as one at 6000 MT/s. The first gives a timing of 12.86 nanoseconds, while the second equals 12 nanoseconds (36 multiplied by 2000 divided by 6000). Their timing details (CAS 36-36-36-76 vs CAS 36-44-44-96) and voltage levels (1.35v versus 1.40v) also vary. Thus, they differ significantly across nearly all metrics. Your system should handle both at 5600 MT/s CL36, though this isn’t guaranteed. Four sticks of DDR5 on a Ryzen processor are more challenging to configure than two. If you need 64 GB and certainty, consider selling what you have and purchasing two 32 GB units.
Perhaps? The key factor in determining compatibility is the memory IC on the kit and the RAM manufacturers' choices based on available options. Because of this, identical model numbers can lead to different kits depending on the speed range. Premium kits are less affected since they usually use fewer memory ICs that match the required speed. For lower-end models like 5600 CL36, more choices exist, making it possible for two different ICs to work well together. DDR5 systems also present challenges with multiple DIMMs, requiring specific BIOS versions and settings, which can be more complex than DDR4 setups. It’s often better to avoid mixing memory types altogether, especially if you don’t need extra capacity.
Sell your existing setup and purchase a high-performance 6000C32/30 2x32 kit. Upgrading to this model will improve your four-stick configuration, though DDR5 still has its limitations and requires significant optimization for meaningful performance gains.
