I need to upgrade my system from 16GB to 32GB, and for future proofing, I figured I'd get a faster kit, for whenever I upgrade to a processor that can run these frequencies without sacrificing a sheep, I actually have fast RAM to use with it.
My current sticks have OK low CAS timings. The faster sticks have some standard JEDEC timings listed, as well those for the frequency they're supposed to run on, but they're slower when compared numerically. Can I take these XMP timings and scale them down accordingly?
Say if these DDR4-3000 sticks I'm interested in do 15-17-17-35 at 3000MHz, could I scale these timings proportionally down to 2133MHz? E.g. (15-17-17-35) * (2133/3000) = ~(11-12-12-25)? Which would imply that I could practically run these at 12-14-14-28 or something? Or doesn't it work like that?

The 12-14-14-27 or so would prob be a good place to start at say 2400
