 In general, you want the highest MHz and the smallest CAS latency.
-I recommend sticking with reasonable speeds to avoid issues such as random BSODs or random restarts.
+For Ryzen 3000/5000, you want to limit yourself to <= DDR4-3600 since the Infinity Fabric clock (FCLK) can only go up to 1800. Going higher than 3600 will cause the FCLK:UCLK multipliter to become 1:2, halving the FCLK. '''Officially, only up to DDR4-3200 is supported.'''
-For Ryzen 3000/5000 and Intel 8th gen, '''only up to DDR4-3200 is officially supported'''.
+For most applications, memory speed has diminishing returns above 3000 so don't spend too much to get better speeds or latency.
-Intel CPUs tend to support faster RAM speeds as Ryzen CPUs' Infinity Fabric clock (FCLK) have their memory frequency directly tied to memory frequency.
