Computer doesn't prefer RAM being overclocked
Just finished a build trying to adjust the RAM clock to 6400, but the computer won’t start or hang after several failed attempts. It boots with UEFI (or whatever it uses) and works fine once XMP is turned off and the clock is set to auto. I’m confused about what’s going on.

Which one is not identical?
RAM is sold in groups for a reason.
Those two sets of RAM might have been made by different manufacturers, with slightly varying tolerance levels.
They might not (seemingly do not) work well together.
If you need 64GB, you should have purchased a set of two 32GB units.
RAM offers significantly more timings than those listed on the package. When multiple RAM modules are sold together, it ensures compatibility for all timings, including those not visible on the packaging. It might seem that two sets of two could function well, but many experiences shared here indicate this isn't always the case.
@Lutfij
suggested a BIOS update as a possible solution, though this would likely stem from improved BIOS handling (which may not be feasible). Even if you upgrade to all sticks in one package, updating the BIOS could be beneficial—though it can be challenging. My guess is the problem lies in purchasing two packs of two instead of a single pack of four.
