I recently bought an AMD 9800X3D and I'm looking to purchase RAM before the prices go up. I'm considering two options: a RAM kit that works with both AMD and Intel and has a total latency of around 9.3ns, and an AMD-optimized kit with a total latency of about 10ns. Both kits are available locally, but the pricing isn't great, so I want to make a decision soon. My main uses for this PC will be Microsoft Flight Simulator, racing simulators, and video editing/rendering. Is it better to go for the lower latency 9.3ns kit or the AMD-optimized 10ns kit? In practical terms, which one would likely provide better stability and performance? Any advice or personal experiences would be greatly appreciated!

Honestly, with the 9800X3D, you probably won't notice much difference between them. I'd suggest going with the AMD-optimized kit since it will have the full EXPO profile and is certified for your setup.
It would really help if you could share the actual speeds and CL numbers of both kits you're looking at. That info usually makes a significant difference in deciding which one is the better choice.
Aim for some good quality 6000MHz CL30 RAM. The true latency difference between 9.3ns and 10ns isn't something you'll likely be able to notice in real-world use. What's more important is having the right EXPO or XMP profiles, which, from my experience, don't really make a noticeable change.

Sorry about that! The two kits are: - Corsair VENGEANCE RGB 64GB (2x32GB) DDR5 6000MT/s CL28 (~9.3ns total latency) - Corsair VENGEANCE RGB 64GB (2x32GB) DDR5 6000MT/s CL30 (AMD optimized, ~10ns total latency)
