before start the post sorry for my bad english 

i got a laptop from tongfang barebone which name is PF5NU1G
or its called as
hansung TFX5470H(i got this)
MECHREVO Code01
Tuxedo Pulse 1
Schenker VIA 15 Pro
KDE Slimbook
Eluktronics Thinn 15

spec is
4800H
VEGA7
16GB 3200 dual

as long as i know these models are have competible bios between each other
my 5470H bios supports fewer options unlike via 15
so im trying to unlock all bios options but i dont solution
i need RAM timing contrl, voltage offset or so.
i want to underclock, undervolting. for more power efficiency
and id like to see all available options if its possible

so i attached both bios files below

i opened my bios threw AMIBCP. at the first time AMIBCP shows 0x08 length error but i corrected it.
check this solution : https://www.win-raid.com/t3859f16-Error-...ght-2.html
it shows many options but still dont have idea what is hidden one.
