DDR4 3800 c14 Ryzen 3900x Optimisations


hi!

i think i get a stable 3800 c14 1:1:1 on zen2. https://imgur.com/a/32cOYim

at the beggin i wasn't able to do it stable, it random crashed with "errors in logical core 4" in occt, but almost everytime with any ram i had this specific error on this specific core, so i sayd to myself "okay dude, is this specific core maybe the weak core of my cpu just try to raise cpu voltage, maybe the cpu need more voltage to get more stable at this fclk compared to my 3600 profil".

so: i had my 3900x static oc'ed at 4.2ghz on all cores at 1.212v, it was rock solid stable with the 1800fclk. but now is 1900fclk so i just tried to rise cpu voltage at 1.248 and… bingo, no more errors.. do u think by just adding more juice to my cpu it solved this? maybe my oc was a little tight but good enought to run 3600 but no enought to run 3800? if i oc fclk i don't have to just play with vddg vddp vsoc? cpu voltage need more juice too? it depend of the fclk oc? did it put more juice to the imc or something? if someone can me explain why just adding juice to cpu resolved it, and if u have any recommendations to optimise my config.

maybe 2T better than gdm+1T on 4 sticks? i don't see any difference in latency or bandwith…

is this worth to try to summon baphomet to stabilise it 1t gdm off playing with cad bus? https://www.reddit.com/r/overclocking/comments/x1bqea/trirank_3801mts_1toff_how_to_summon_baphomet_with/

i hear that 7-3-3 park was better for 4 sticks than 7-3-1, any ideas?

i don't think i have to low my trfc at 130 cauz very low latency benefits at this point for the heat generated, i prefer stability 24/24 for audio workloads, maybe i'm wrong and i can go as low as possible? (i'm not sure i think if i put trfc to low the ram instability come faster with dimms temperatures or i am wrong?

vsoc vddg and vddp have to be optimised? or that's good value and "it work don't touch it"?

and last question: is a good bandwidh? can i maybe approach 60k by optimising subs? or windows direcly maybe? i see lot of screens at 60k at 3800 but a bit more latency, maybe is better to accpt this as this good zen2 latency? (i think is a good latency for cpu with 2ccd and 4 sticks no? or u have a secret trick to go under 60ms)

i run 4x8g gskill neo 3600 cl14-15-15-15, ryzen 3900x (yeah i know but i don't have money theses times to spend on the 5950x so i wanna try to get the best possiblme of actual cpu), rtx 4070fe, gigabyte aero g x570s

occt 1 hour cpu+ram large set extreme mode, variable load, prime 95 512-2048, and tm5 incoming. not many tested but i have this smooth feeling on the bios u know? whern u scroll with a bad oc and lot of struggle and mice glitchs, is smooth this time.
