You're asking for clarification on why your system can't achieve DDR5-6400. There might be several reasons: the RAM might not support that speed with those clock speeds, the CPU could have insufficient memory timing, or the motherboard traces aren't designed for such performance. All three parts—RAM, CPU, and motherboard—play a role in enabling RAM optimization. If you managed to run DDR5-6000 on DDR5-5200, that's already impressive. Your current setup with DDR4-3000 should handle DDR4-3333 without issues. However, going above that won't work regardless of voltage or timing changes. The maximum you can reach is determined by the hardware limits, not by endless adjustments. Eventually, you'll reach a ceiling, and you've reached yours. You can stop here unless you're interested in fine-tuning timings further. No component can be permanently optimized forever; silicon has its boundaries.
You're asking about why performance fluctuates around 6400 MHz and whether the system gives subtle signals about its capabilities through BIOS settings. It's a common concern when optimizing for speed.
I should mention that I managed to get DDR4-3600 to start a few times on my machine, but I encountered blue screens and occasional POST failures. That indicates the overclocking stability is poor. Unpredictable performance suggests the OC settings are failing. Consistent issues point toward a failed overclock. It doesn’t prove it will work reliably. If you really want higher speeds, consider purchasing better RAM. If you're just experimenting, that’s acceptable—it’s your device, how you use it matters. I wouldn’t expect anything to run smoothly at 6400 unless you push the limits too far. You might try adjusting timings or increasing voltage slightly, but that’s limited. It’s not a hidden setting that can fix this on its own. For everyday use, I’d avoid pushing OC too hard to maintain stability.
