G.Skill's F4-4000C14D-32GTZN model
I reviewed the specifications on PC Part Picker and discovered the 10900k wouldn't support these RAM sticks at full speed. The Trident Z Neo requires a voltage of 1.55 V, which is higher than the Intel Comet Lake's recommended 1350 mV. It might need a lower clock speed or a higher voltage, or you may need a different CPU like the 11900k.
Technically you don't have to boost the CPU speed, but the memory controller needs careful adjustment. These extremely fast memory modules demand extensive calibration to function properly. Running them at full rated speeds might shorten your CPU's lifespan because they require higher voltage than suggested. You can purchase these components and activate XMP settings, but it's wise to anticipate a CPU upgrade before issues arise. A 3600CL14 model should suffice and operate within the recommended voltage limits.
Skip the fast RAM and don’t waste money on a 10900k or 10850k if you plan to overclock. Instead, opt for a 5800x or a 3600mhz CL16 setup—use CL18 sucks balls if you need an APU.
It doesn't relate to the CPU OC settings. I have a lower voltage stage and it uses 1.5V on RAM for CL15 and 1.65V for CL14 at 4000MHz. It's just about RAM power, I/O, and SA voltage. If you don't need the lower specs, stick with 3800 or 3600.
Using 4000MHz with those specific timings (16-16-16-36) keeps the parts picker silent, probably because it fits within the allowed range.
I'm not entirely convinced by most of what was shared here. This kit seems to be designed for 12-12-12 operation, but likely at a significantly higher voltage. From what I understand, this voltage doesn't seem to shorten the lifespan of chips. The newer chips I own haven't been exposed to liquid nitrogen on their chips either. I've managed to run 14s at 4000MHz, 16s at 4200MHz, and 17s at 4267MHz. The memory controller reaches its limit around 4300 before timing issues or voltage spikes above 1.6V occur. Yes, I've tested b-die circuits at 1.5 to 1.6V daily. If you want proof of any statements I've made, just let me know. Good luck with your builds! Just make sure your equipment stays cool. That's the key point. Aim for 40-45°C under load, and consider using a fan.
I'm sharing this idea here... But ^^^ that person there really taught me how to OC my B-Die and I got great results. Unfortunately, my board is capped at 1.85v for the MEMS, so I’d look at 3200C14, 3600C14 all flat, and 4000C14. Those should be your best B-Die options, aside from the 5000MHz stuff... probably. A 1.55v setting isn’t too different from 1.35v if you adjust it a bit, so feel free to try.
