I have issues with tuning hynix a die 6000 xmp 30cl kit with higher frequencies

board is z790e strix (1st version, not the refresh), 2801 version (i don't wanna run 0x12F, and later bios versions have no mention of improved memory handling)

LLC6 (with additional -0.05v at later stages of vf curve & -0.03v ring) , SVID trained, 55pcore, 42ecore, 47 ring, 1.45 voltage/400 amps/400 watts limits (i have noctua nh d15 g2)

Right now my voltages are:
– 1.5 VDD
– 1.45 VDDQ
– 1.9 VPP
– 1.18 SA (anything above 1.22 is full gulag, 1.18 takes longer to error out in VT3 than 1.2)
– 1.38 IMC VDD
– TX left to auto
– 1.84 VCCIN_AUX

ram is actively cooled with smol noctua fans

current timings at 6600, 62ns aida: https://imgur.com/a/60oi5NQ

round trip latency training always fails so i have that off ;_;

at 6600 VT3 errors out after 8mins
i tried making 6800 works but even at 1.65 VDD, 1.5 VDDQ, 1.45 IMC it was not stable

can anything be done with the timings? or is it just IMC on my 13900k that's just trash?
