I have an AMD Ryzen 5 7600 and recently started experiencing stuttering in games after several years of smooth performance. My system currently has 16GB of DDR5-4800 CL40 memory, and I was told that I should have used 16GB of DDR5-6000 CL30 instead. I'm not very familiar with memory specifications, so I'm wondering how significant the difference really is. Could the slower RAM be causing the new stuttering, or should I investigate other hardware and software issues first?

Your current DDR5-4800 CL40 memory is slower and has higher latency than the commonly recommended DDR5-6000 CL30 setup, but it should still be functional with this processor. Make sure the memory is running in dual-channel mode and check the BIOS to see whether an EXPO profile is available. I would troubleshoot the stuttering first and only upgrade if you also need more capacity or want a small performance improvement.
DDR5-6000 with lower timings is a better match for the Ryzen 5 7600, but it would not suddenly become a problem after working normally for years. The difference is usually a modest performance improvement, not an explanation for new stuttering. If you upgrade, 32GB—preferably a 2x16GB DDR5-6000 CL30 or CL32 kit with EXPO—would make more sense than replacing it with another 16GB kit.
Since the stuttering appeared recently, start by looking for a recent change rather than blaming the memory speed. Check CPU and GPU temperatures, background programs, graphics drivers, disk space, game updates, and whether your system is running out of RAM or VRAM. A clean Windows installation may also be worth considering if the current install has been used for several years.
Open Task Manager or use an overlay such as MSI Afterburner while gaming and watch CPU usage, GPU usage, RAM usage, VRAM usage, temperatures, and frame times. If RAM usage is close to full, moving from 16GB to 32GB could help. If GPU usage drops while one CPU core is maxed out, you may be hitting a CPU bottleneck instead.
What is the easiest way to monitor those values while I’m playing?
I already addressed the overheating by replacing the thermal paste, but I haven’t done a clean Windows installation since building the computer.
