auto wont do.
asus default on z370 is actually tight.
here is the kicker. on p95 i find alot of bsod errors 5.1ghz above are ram/imc related even on fft12.
5.1ghz relaxing rtl/iol passes fft12.
also passes hci.
but then i get some pcie issues ( tested on long stream)
games tested is deus Ex and now my new fav is fc4 with all gameworks enable.
did some tweaks in tweakers paradise and upped dmi/cpu standby voltage. m
5.2ghz again another imc related issue. tweaked some third timings,
5.3ghz was hci/priming with rams at 4200c18@1.3v.. thsts when i killed one of the cpu cores. lol.
pll bandwidth helps but becareful n dont use 6-8 as whats written on the description. default intel spec is 1.2v but asus runs it at 0=0.6v
hope this insight helps. i just backed down to 5ghz@1.2v offset 2 and called it a day. need months to validate above 5ghz since its causing other issues via dmi.
same issues i had with my 7820x when i oced 4.7gh fod ram 4kc17@1.3v. rb/p95/hci doesnt catch other issues as much as actual long session gaming.
