I'm working with a Ryzen 9590X and an X870E Proart motherboard, and I've got two packs of Kingston Fury 64GB CL32 RAM. While I can run 64GB at the rated speed just fine, adding another 64GB to hit 128GB doesn't seem to work—it won't post. Is it feasible to run the RAM at a lower speed for stability, or would that compromise performance too much to be worthwhile?

Have you checked if Expo is enabled? Sometimes that setting helps with stability when running high-capacity builds. Just a thought!
Keep in mind that using two sticks per channel can reduce signal integrity, which impacts your maximum frequency. While you might get somewhere around DDR4 5200-5600 with 128GB, hitting 6000+ is probably unrealistic. By the way, what speed are you trying to achieve?
The RAM is rated for 6400, but I haven't manually adjusted the clock settings yet. I'm hoping to get this sorted out, but it's frustrating watching it fail during training!
I tried enabling it, but that caused more issues with posting.
