Looking at the options, the 3600MHz 14CL 32GB setup offers the best balance for your needs. It should deliver top performance in gaming and streaming, with high bitrate capabilities and solid editing support. The 64GB version would push you further but might bring a noticeable drop in frame rates compared to the 32GB configuration. Your goal is clear—prioritize speed and quality without sacrificing too much on other fronts.
The variation is around 1% on average, which isn't a big deal. Also, the main timing doesn't significantly impact performance compared to the hidden secondary delays. If you need to cut 32GB of RAM just for a few extra frames per second, it's not worth it—add more RAM if you really need it.
If the prices are nearly identical, the 3600MHz model is likely superior for simply enabling XMP and finishing the job. If you plan to customize further, the 3600MHz version might offer better performance, potentially yielding more clocks or tighter timings during manual tuning. I own a 3200MHz CL16 with four 16GB modules and have successfully run it at 3600MHz (CL14 or CL16) after tuning manually—it’s far more involved than just applying XMP.
Which option would work better for your needs? Comparing the two timings—3600MHz 16CL versus 3200MHz 14CL—depends on what you prioritize. If budget isn’t a factor, using the d-ram calculator for the 3600MHz 14CL setup is a solid approach. Regarding your question about tuning: yes, it’s possible to adjust a regular 3600MHz 16CL clock down to 3600MHz 14CL, though performance may vary.
The 3600MHz CL16 will surpass the 3200MHz CL14 significantly thanks to Zen2, and running the FCLK at higher clocks further boosts performance. I began with a calculator before making manual adjustments.
I bought Team Group Dark Pro 3600C16 and run it at 3800C16 with FCLK 1:1. Probably could get those timings down a touch more but I'm OK with were they're at. Pretty much any B-die kit will do. I opted for 3600 cos I'm already at that sweetspot if I want to back the OC down for whatever reason.
The choice of 3600MHz is mainly due to the fact that faster RAM boosts the Infinity Fabric speeds, which most noticeably affects performance. Even without considering the Infinity Fabric, the 3600MHz CL16 remains quicker than the 3200MHz CL14.
I understand, thank you for the details. It seems the 3600MHz 14CL tuned at 3200MHz can shift to around 4000MHz when adjusted, but the optimal range for performance is closer to 3600-3733-3800MHz with perfect clock stability. That suggests the 3600MHz version might actually run better than the 4000MHz one if timings are fine-tuned. You could potentially adjust the settings on the 3600MHz tuning, but it would depend on the specific clock accuracy. It would be helpful to know your motherboard model for more precise guidance. Thanks again for your patience and support!
