i was led to believe ALL the sniper stuff will be b dies

allthough cl19 seems a bit steep for 3600 even on ryzen
i have cl18 but at 3866 ram sticks and they are 100% b dies

cl14 at 3200/3333 and so it seems at 3466 (allthough it will throw a cold boot issue after 1-2 weeks )

No, they are definitely not B-die, thaiphoon says are manufactured by hynix, the closest thing that says to b-die, are 8G M-die XD.

So not all sniper X are b-die, so my 3400 17-17-17-37 are my best free very good error stable setup. Smile

Thanks for the help.

Thanks

Sorry late, was busy working. 

GOOD NEWS, SoC voltage 1.312v is the LAST_KEY, plus dram voltage 1.44v plus VTT 0.72v,  immediately gives me 3200mhz again, bios_uefi_4.7_taichi_x370 really helps !!!!  http://valid.x86.fr/76sqea

BIOS UEFI version 4.7 taichi x370 allows SoC voltage as high as 1.4v then shows red color warning.

When I was on older bios uefi version 3.2 the SoC voltage would show red at 1.2v hence I never used higher than 1.2v.


Timing for Cuba1hr from 3200mhz then 3066mhz finally 2933mhz

3200mhz, now, just happened.


3200mhz lowest timing from my record



3066mhz

@ cx5 - thank you so much. I'll have material to play with in next few days or weeks.
I didn't count on new beta to be available "so soon"...so I'll try that next and after play with your settings
There's also announcement of new version DRAM Calculator for AGESA 1.0.0.4 on earlier link so we'll see differences, what will change in recommended settings and compare.
