Is 4000Mhz a good investment?
I design a new setup and consider high-speed RAM. The CPU is the 5900X... What memory speed can Ryzen achieve for strong performance? I think when DDR5 comes out, its starting frequency might be around 3600MHz perhaps? If I get 4000MHz, would that be better than this? Or should I opt for 3600MHz and try to overclock it?
The optimal memory speed for a Ryzen 5000 really hinges on your specific chip selection. Certain processors are limited to around 1800 MHz fabric, making DDR4-3600 the best fit, while others can reach 2000 MHz, which suits DDR4-4000. 3600 offers a reliable choice, and going beyond that usually means extra effort—better to invest in solid overclocking potential instead of chasing XMP ratings.
You're considering adjusting your memory settings yourself. For speeds over 3600, the chip must be manually boosted because AMD can't ensure stability beyond 1800. Skipping this step could mean your 4000 with unoptimized memory will lag behind the 3600 version with tuned memory.
it's a very low chance that you will get a chip with an imc that does 2000/4000 with 4 sticks, the safe bet is to get 4 sticks of 3600 and see how high it goes, most will do 3733 just fine.
