No, the Aorus B450 Elite Pro does not support 4000 MHz RAM.
Is the Aorus B450 Elite Pro able to use 4000 MHz RAM? Since your friend is a graphic designer or gamer who wants a 4000 MHz RAM upgrade, does this model support it?
The B450 Elite Pro isn't available in Aorus Elite or Aorus Pro models. The performance of 4000MHz also hinges on the CPU used, but for Zen 2 systems, aim for 3600MHz. You can lower the memory speed if needed, but if the price exceeds a 3600MHz kit, it may not be worthwhile.
4000MHz RAM may lead to lower performance compared to 3600 because the infinite fabric won't operate at a perfect 1:1 ratio, causing a drop in efficiency similar to what you'd see with 2666.
Additionally, if the person you're talking to is a graphic designer, opting for 32GB at a slower connection would be more suitable.
You're typically aiming for a max frequency around 3200MHz thanks to Zen+'s memory controller, though 3000/2933MHz is more reliable. 3200MHz CL16 units are usually competitively priced and provide solid performance. Let me know if you'd like me to send you updates whenever you reply.
The CPU's memory management only defines a maximum of 2933 MHz RAM. Therefore, he might need to rely on XMP settings that accept any higher value, or he may have to manually increase the frequency for stability. The motherboard's memory controller can handle up to 3600 MHz (B450 Pro Aorus).
