Just picked up the new 9950X3D and looking for optimal DDR5 recommendations. I've seen conflicting info about whether to go with DDR5-6000 CL30[1][7] or push for DDR5-6400[8] speeds. Planning on 32GB capacity for gaming and content creation. Using 4 sticks seems problematic above 5200MHz[5], so probably going with 2x16GB. Any real-world experience with this chip? What kits are you running and how's the stability? Thanks for any insights!
For the 9950X3D, you'll want to focus on DDR5-6000 with tight timings rather than chasing the highest speeds. AMD's sweet spot is still around 6000-6400 MT/s due to the FCLK limitations. I'd recommend G.Skill Trident Z5 Neo DDR5-6000 CL30 or Corsair Dominator Platinum RGB DDR5-6000 CL30. The Neo series is specifically optimized for AMD and tends to have better compatibility. Make sure whatever you get is on your motherboard's QVL list.
