I'm setting up a new PC with an X870-F motherboard and a 9800X3D CPU, and I need some advice on RAM. Unfortunately, I can't find G.Skill Royal EXPO RAM in my country, so I'm considering going with XMP instead. Can anyone explain the real difference between XMP and EXPO? Since I'm primarily gaming, which would be better for 4K gaming: the 6400 CL32 XMP or the 6000 CL28 EXPO? I can get the 6400 CL32 XMP with warranty locally, but the 6000 CL28 EXPO would have no warranty if I buy it from abroad. Is the warranty a major concern here?

XMP is Intel's overclocking standard, while EXPO is designed for AMD systems, though many motherboards can support both. For 4K gaming performance, you'll find that while lower latency (like 6000 CL28) can be slightly better for responsiveness, the higher bandwidth of the 6400 CL32 XMP can also be advantageous. Given that the 6400 CL32 XMP is available with a warranty in your area, it’s a safer bet, especially if your motherboard handles it well. If you want to risk it with the 6000 CL28 EXPO from abroad, just confirm that your motherboard is fully compatible with EXPO profiles. Either way, you’re good for gaming, but reliability often wins out.
With a 9800X3D CPU, the difference in frequency or latency is minimal for gaming. A 6000 CL30 or 28 should perform just as well, especially on AM5 platforms. If you decide to go with the 6400 CL32, just ensure to set UCLK=MCLK after enabling XMP or EXPO. In 4K gaming, CPU limitations are less of a concern, so the choice doesn’t greatly impact performance overall.
You should know that XMP should still work on AMD setups, it’s been reliable for years. If you can manage to find a 6000 CL30 or 28, I'd suggest you go that route for lower latency. Otherwise, just get the 6400 CL32 for peace of mind. That wouldn’t hurt your gaming experience either!
What do you mean XMP might not work? It has been fine on AMD for ages, even before EXPO came out!
Right? If the 6400 CL32 has warranty, that's a strong incentive. Honestly, both are solid, but reliability can be crucial!
