Hey, i know ddr4 is getting old but i managed to grab a beast b die for cheap, and replaced my 3600mhz cl16. In aida64, the latency dropped from 64ns to 57. For an x3d chip i think its a pretty decent drop but in real world performance it may not be so impactful. Trfc doesnt go down past 250 so i backup up to 266 just in case. The most unstable timing seens to be TRC, testmem5 pass multiple hours but one tick down in trc and it start to randomly throw errors.

Honestly, I’m surprised that you got this far.
Those are really, really tight timing.
See if Gear Down mode off works. Other than that, you’re kind of done here.
Cwl might do cl-2 but gdm on means cl-1 = cl because no odd timings
CWL can go to 10
raise tRDRDSCL and tWRWRSCL to 3, disable GDM. If that works, you can try lowering them again.
doubt fabric is really stable but eh
