To determine whether your PC is compatible with the installation of 2x16GB at 6000MHz and 2x32GB at 5600MHz on 4 slots, it is essential to check several points:
1. Frequency compatibility: Make sure your motherboard supports these frequencies. DDR5 memory kits may require adjustments in the BIOS to operate at higher frequencies.
2. CAS latency compatibility: The CAS latency of the modules must be compatible with the capabilities of your motherboard.
3. Qualified Vendor List (QVL): Check that the memory modules are listed in your motherboard's QVL to ensure optimum compatibility.
The price difference between 16GB 6400MHz kits and 32GB kits depends on your needs in terms of storage capacity and performance. If you need more capacity, the 32GB modules might be cheaper.
Of course you can do that. However, it has to be said that the 6000MHz+ will then be of no use to you because the CPU will not run faster than 4800Mz on all 4 slots. Greetings
