Hey everyone! I'm in the process of building an AM4 system and plan to reuse my old DDR RAM sticks, which both have a speed of 3200MHz but different latencies. I'm looking to pair it with a Ryzen 7 5700X, but I've gotten mixed advice. Some folks say it's fine to turn XMP or even disable it, while others warn against mixing RAM sticks with an AMD CPU. Since I'm not very technical and don't have any expert friends, I'm feeling uncertain about the risks. If I were to consider an Intel CPU instead, which one would be equivalent to the Ryzen 7 5700X? A slightly better option would be great, too, as long as it doesn't consume too much power. I'm also planning to pair it with an RX 6900 XT. Thanks!

I wouldn't recommend going with Intel, especially considering the RAM situation. You could run into issues where it might not work at all, or it might default to the speed of the slower RAM. XMP can be tricky to manage in this case!
Mixing RAM sticks isn't ideal, but it might not be a huge issue if you manually tune them to get decent performance. In terms of Intel equivalents, the Ryzen 7 5700X is roughly comparable to the Intel i5-12400F or i5-12600K/KF. You could also look at the i7-10700K, i7-11700K, i9-10900K, or i9-11900K, though the newer generations like the i5-14600K and i7-14700K are great for gaming and multitasking. Just remember, if you go Intel, always update the BIOS to the latest version for the best performance!
If I want to manually tune the RAM, how do I do that? Do I just set it up in the case, turn it on, and what happens if it doesn't work? Will it default to the baseline speeds without XMP?
If you're leaning towards Intel, I'd say go for the i7-10700K or i7-11700K. I’ve had the i9-10900K before, and it worked well with XMP set at 3600MHz. But if you want something newer, check out the i5-14600K or i7-14700K. They’re really solid for gaming and handling heavy workloads, even if the e-cores aren’t much help in gaming. Just make sure you update your BIOS if you go with either of those CPUs!
If I install everything, power it up, can it fail outright, or will it just fall back to 2133 MHz without XMP? Just trying to figure out my tinkering options.
