I have been previously trying and failing to stabilize an 8000cl40 2x24gb kit on this system, so I decided to switch to a 6000cl28 1.4v kit – which ran expo stable for 100k% on karhu – yay!
So, this is a start with a 2×16 6000cl28 kit – I am a bit surprised it was ok with lowering vsoc and vddio a little. I tried 6400 with 2133 fclk at vsoc 1.25, vdd 1.44-1.45, vddq 1.42-1.43, and vddio 1.4 but it wasn't even close to stable – basically BSOD'd as soon as I started karhu. I'm guessing 6400 stable would take a lot more on some voltages.
I'm ok with 6200 if it's "before the voltage cliff" for my setup, but any suggestions on timings to tune further? My sticks get up to ~55c even with a fan pulling air across them (gskill) so I don't know yet if lower tRFC is viable/worth pushing. I haven't tested GDM off on this kit yet, but I did sync the tPHYRDL and this screenshot is currently at nitro 1/3/1.
Alternatively, if people have suggestions for good 6400 settings to try I can give them a shot. Thanks for any suggestions!

Same cpu, same kit. Just copy paste and disable gdm. Can keep same uclk/fclk/mclk if you want.
Will bump bandwidth by some 10gbps and lower latency by a few ns
