DDR4 overclocking vs DDR5: DDR5 wins on architecture, not just speed

The gap isn’t just speed — it’s architecture. DDR5 has higher bandwidth per clock, better efficiency, and on-die ECC that DDR4 can’t replicate no matter how much voltage you push. Even if you squeeze DDR4-3200 to DDR4-4000+, you’re still stuck with the old memory controller and narrower bus, so a stock DDR5-4800 kit outperforms it in real-world tasks. Modern CPUs are designed for DDR5, so chasing DDR4 overclocks to match is like hot-rodding a Camry to beat a Model 3 — save for a platform upgrade instead.
