It's tricky to determine based on your area or market, but as @Downkey suggested, aim for matching speed, capacity, and timing. You can use CPUZ to view the SPD section and discover your benchmarks. Even if results differ, they should align with the fastest/lowest speeds available together. https://www.cpuid.com/softwares/cpu-z.html
Match your RAM performance by ensuring both slots operate at identical speeds and latency. Verify your current RAM's CAS latency through Task Manager or CPU-Z; once identified, compare it with compatible options to maintain optimal stability.
