It's somewhat complex because the "initial delay" figure only represents a small piece of the overall picture. Many other factors related to memory speed matter more for how well the system performs. Also, basic memory delay isn't the key concern—it's how quickly the memory communicates with the CPU core, which depends on ring clock, CPU clock, and memory clock. At similar scaled settings, higher frequency can actually reduce effective delay. The real impact depends more on the specific workload; it could be negligible or noticeable in 5-10% depending on how much data the system handles. This depends on several elements: the motherboard, CPU, and RAM modules all play a role. Superior boards often feature cleaner wiring for better signal, enabling higher memory speeds. The memory controller is integrated into the CPU and varies greatly in quality between different processors, especially on Intel chips where speeds can exceed 1000MT/s. Voltage requirements also differ widely. RAM modules themselves are designed for higher clock speeds, and the motherboard's BIOS can significantly alter performance limits. I've tested three 13th generation CPUs, and while memory controller compatibility was fairly consistent, I had to adjust voltage settings across different models. The Hynix A die in RAM kits is reliable for consistent performance, while the exact voltage settings matter most. The BIOS on my Z690 board changed voltage requirements between revisions, affecting what works best. Every kit is built from multiple components—chipset, PCB, controller, and more—each influencing the final outcome. For clarity, every kit comprises four main parts: the memory IC, the PCB, the controller chip, and sometimes a PMIC. DDR5 modules use Hynix A dies, which tend to deliver similar settings across brands, though SPD variations and voltage specs can differ. Choosing a kit with Hynix A is usually ideal for stability and value, especially on Z790/AM5 boards. If you're only aiming for XMP without overclocking, it's less critical. The Z760 isn't a chipset but a platform; BIOS updates can shift performance expectations. Z690 supports 14th gen, and most manufacturers have updated BIOS versions. It's not a major concern unless you're targeting extreme overclocking. If you're unsure, sticking with well-reviewed boards like Gigabyte or Tomahawk is wise. I favor the rear IO, solid BIOS support, and a reliable VRM design, but personal taste varies. Phantom Spirit remains a strong contender if budget allows.
@RONOTHAN## Looking for more details on AIO choices and case fans. If you prefer the be quiet! Silent Wings Pro 4, would that work well? Any other suggestions?
Arctic Liquid Freezer II is often a solid choice; aim for a model with at least 360mm (280mm works too). It delivers solid performance and comes with a VRM fan that could handle the demands of newer processors. Generally, it offers good value, especially when compared to other models. The Arctic P12s are currently among the best in price and capability. For those seeking higher-end, quieter options, I haven’t focused much on premium lines, though the Phanteks T30 stands out for performance and the Noctua A12x25 is a close contender, possibly due to its thickness rather than noise levels.
It looks promising! The AIO version adds a bit more cost compared to air cooling since I won’t need the two top fans. Overall it’s just a few extra pounds. Right now the setup resembles this link: https://uk.pcpartpicker.com/user/RobGMun/saved/nHCkD3. I’m researching the RAM and don’t have to worry about that yet. I switched the power supply to something rated A-Tier from the Cultists Network list. I also considered an 850W unit, but I found a 4080 for £102 less and a processor for £46 cheaper than what’s listed. That brings the total to around £2239.22 today. This is near my budget limit, so I’ll see what Black Friday offers. If I can save a few more, it would be great!
