It's not about a specific solution, it's a general hardware constraint. The DDR5 memory controller in Alder Lake performs poorly, and the memory layout on the 4 DIMM boards is even less ideal. On those setups, running two 32GB modules caps speed at around 6200MHz, with 4x16GB dropping to about 5400MHz. Going to four 32GB modules pushes the limit to roughly 4800MHz—especially if Intel's limits are taken into account. Many here avoid DDR5 because it's still in its infancy, packed with challenges, and only works reliably on boards with a 1DPC architecture like Tachyon, Aqua OC, Unify-X, Apex, or mITX. Most motherboards don't support even 4x32GB stacks, making that configuration essentially non-functional. Alder Lake's DDR4 controller handles the job just fine, and unless you're certain about performance parity, it's wiser to stick with a more established platform. If you still want to try, cap it at 4000MHz—anything higher is unlikely to improve significantly.
