Hey everyone! I'm gearing up to build my new PC and am currently on the hunt for RAM. Unfortunately, I decided to do proper research just as RAM prices shot up! I've found some 6400 MT/s CL32 RAM sticks that seem to offer the best value right now, but I've come across recommendations for 6000 CL30 sticks — which are about 50-100€ more expensive. Since I'll be using a Ryzen 5 7600X3D processor, will I be okay going with the 6400 CL32 RAM? I've seen different opinions online regarding the best choice, so I wanted to get your thoughts.

No worries, you'll be fine with the 6400 CL32. If there are any problems, just reduce the speed to 6000 in the BIOS, and you should be all set!
The performance of 6400 CL32 sticks is pretty close to that of 6000 CL30, so you're not really losing out. Just some minor differences that won't be noticeable in everyday use.
Honestly, the difference between CL30 and CL32 is so minimal that most users wouldn't even catch it without performance tests. Just remember to lower the speed to 6000, as RAM over that can be a bit unstable.
Going with the 6400 CL32 RAM is totally fine! Just keep in mind that you might need to manually downclock it to 6000 in your BIOS to maintain that 1:1 UCLK:MCLK ratio if you encounter any issues. Overall, it should work well with your setup.
6400 CL32 has timings comparable to 6000 CL30, making it a solid choice. If your CPU runs into any issues with 6400, scaling it down to 6000 shouldn't cause any problems at all.
