As noted, the new G.Skill memory kit uses eight 32GB modules and runs at 3,600MHz with CL16-20-20 latencies and runs at 1.35V.
It is validated on Ryzen Threadripper 3990X platform, and G.Skill released a validation screenshot on the Asus ROG Zenith II Extreme Alpha motherboard.
The new Trident Z Neo DDR4-3600 CL16-20-20 256GB (32GBx8) uses G.Skill's recognizable heatsinks with RGB support.
Unfortunately, this new memory kit will not be available until Q2 2020, so those looking for a high-capacity, high-performance, kit will have to wait a bit longer.
