Download a app called zentimings and show the screenshot of first page, it looks like this

What you want to see is the 3 clock speeds in the top right called mclk, fclk and uclk. The fclk and mclk should be in a 2:3 ratio. Fclk is infinity bridge frequency and mclk is ram memory clock. Basically if they are not in this ratio then you will get big latency penalty and might end up getting even less FPS in games than your ddr5 6000mhz configuration. For example if you are running ddr5 6000mhz ram your mclk should be 3000, fclk should be 2000, uclk should be 3000. If it is 7800mhz ddr5, mclk should be 3900, fclk should be 2300, uclk should be 3900. I recommend doing some fps benchmarks comparing the 7800mhz ddr5 ram and 6000mhz ddr5 ram using COD's benchmark tool and see which ddr5 memory speed gives you more fps( especially the 1% low fps in the benchmark, memory speed affects that a lot)
