[REQUEST] ACER Helios 300 PH317-53 2019 GPU 2060 Bios Advanced Menu Unlock

Hello I have the laptop mentioned in the title. I need the bios unlocked for modding and setting up XMP profile for memory. If someone can help me please do let me know i do have dump. I am attaching helpful files and links.

Thank you

BIOS version: 1.12 (insydeh20 rev 5.0)
FPT DUMP: biosreg.zip in attachments

fpt write error:


biosreg.zip (6.04 MB)

first must disable BIOS LOCK
this DUMP + edit

after this is possible flash this back .,.or only brick your device :confused:

try the ACER forum or similar search
some bios have hidden ""combo key"" for ADMIN access "no need mod" - example MSI

for XMP you have access ?
any OC tab is here ???

edit - CPU-Z
memory tab vs SPD tab .,.send screen

// combo key -example

how to do this?

already tried 5+ combinations for different acer lenovo and hp laptops

dont have access to any RAM settings in BIOS or in intel XTU software, in advanced tab there is only VT enable/disable settings, i want to edit default timings conf



why you need XMP .,not have XMP memory ?

try any “research” …,find admin hotkey for bios
or wait for better help “I know how to unlock it for flash/dump” this is all .,…,but how to mod bios you need good mod or only gets brick you machine !!

variables written above “your bios” for someone more experienced on INSIDE bios
,.but all advanced setup here exist “admin key must exist”

good luck and try wait .d

i want to overclock current memory by custom profile as i see in variables.txt in advanced tab there is option for set RAM timings/clocks

variable offset
and enable XTU INFERENCE ? - this enable ram in XTU

any problem in variable - cmos reset
but exist some options "pcie setup / me fw" - dangerous …,here is impossible reset device or get old state !

try older XTU ,. last version for me not react on XTU INFERENCE ON/OFF "but my is old 7TH notebook"
exist two type access "when works XTU INFERENCE in bios" - you have all in XTU + RAM

///////// usefully functions

OC TAB - on MSI "new single tab in bios - OC"

Setting: OverClocking Feature, Variable: 0x1B7 {05 91 D1 04 D2 04 CB 01 03 00 B7 01 10 10 00 01 00}
Option: Disabled, Value: 0x0 {09 07 04 00 30 00 00}
Option: Enabled, Value: 0x1 {09 07 03 00 00 00 01}

XTU inference
Setting: XTU Interface, Variable: 0x1B8 {05 91 D3 04 D4 04 CD 01 03 00 B8 01 10 10 00 01 00}
Option: Disabled, Value: 0x0 {09 07 04 00 30 00 00}
Option: Enabled, Value: 0x1 {09 07 03 00 00 00 01}

.,.,but changing need small skill
RU EFI is tool for this

try wait
tomorrow I’ll take a picture of how it works on my Nb

its not hard ,.,but good is know how can is possitible do easy way "CMOS RESET"
long press power button ?? "I only know MSI "


you have to wait for better INSYDE support ,…,on my AMI / MSI works all this but I do not guarantee it on INSYDE bios “not tested” !!!
if you need more info PM but some edit in NVRAM is still dangerous “not all options is normal possitible reset by cmos reset” ,.,infinity boot loop / no screen .,.,etc

I think it’s an unnecessary risk :confused:
