[REQUEST] 10750H Asus G712LWS.314 bios unlock/xmp features
#1
Dear users/mods!
Can someone help me with my "locked" bios? I wanted to undervolt my laptop, but Throttlestop is locked when i will decrease my CPU voltage. My DDR4 ram runs also at 2933mhz, should at 3200. Screenshoots attached (can't dump my bios file). Can some1 help? I want to donate too!

Hello Henndryk,

I can take a look at your request.

Please run this utility by Serg008 as Administrator to backup your BIOS: https://www.bios-mods.com/forum/attachme...?aid=22399

It will produce a results.rar file on your Desktop. Upload that file here. If you can't find a results.rar file, look for a folder on your Desktop starting with "result". Please also upload pictures of the BIOS settings you can see currently.

A lot of laptops have recently had their undervolting capabilities disabled by a BIOS update due to the Plundervolt vulnerability. You can read up on this vulnerability online and decide if this vulnerability and its level of risk and requirements for exploitability warrant removal of the undervolting feature.

That said, there are likely hidden settings that handle undervolting directly or that can disable the undervolt lock itself. We will know once we look at your BIOS dump.

Hi Steven and thank you for your reply.
https://www.sendspace.com/file/ej4gz2 Here is my BIOS backup.
I've already an 'undervolt' option in BIOS but is maxed out up to -80mv. I guess so I need more, and like to 'unlock' those features from ThrottleStop as mentioned above(screenshoot with locked TS). Im glad so there is someone who can directly help. I send pictures from my bios in pair minutes.
Best regards!

EDIT: PICS ATTACHED

Wow... 80mv is a small undervolt allowance... Plus it would be nice to be able to undervolt the integrated GPU too, I imagine.

There are hidden Chipset and Advanced2 Menus that contain a diverse plethora of interesting settings, such as XMP profiles, overclocking, thermal, and more. Maximum Memory Frequency in particular allows you to set your DRAM frequency up to 6200 (though I'd highly recommend against going that far!). You can use AMIBCP to check which settings are available in the Chipset and second Advanced menus. In the left pane, double click the topmost folder without a name, then double click Setup to find the Chipset Menu. The second Advanced Menu is further down. The selected menu's settings will show up in the right pane. Find AMIBCP 5.02.0031 on this page: https://www.tweaktownforum.com/forum/tec...lity-tools

As for the undervolting lock that prevents you from using Throttlestop, I may need to compare the first BIOS version that implements Plundervolt protections with the BIOS version immediately prior and see how the protection was implemented if there isn't a setting that disables the protection. I will get back to you on this. If I am unable to figure it out or there is too much involved, we may have to downgrade your system to a previous BIOS version and modify that version.


It appears that your system may implement Intel Boot Guard. If your system manufacturer did fully and properly implement this (they sometimes don't), flashing a modified BIOS image could result in a bricked system. For this reason, we are going to need to check if this is implemented fully. I will post more details on how to check this later.

In any case, due to the potential presence of BootGuard, I highly recommend purchasing the CH341A programmer. It is about $10 and comes with a cheap clip* that you can attach to the SOIC8 BIOS chip on your motherboard to read and write firmware from/to it. This will allow you to recover given the small chance that this mod results in a brick.

*I was unable to get a reliable connection with the included clip and had to purchase the Pomona 5250 clip separately to flash mods on my test laptop. That said, others have reported that the included clip worked for them.

Hello,

My apologies for the delays.

Intel has this tool called meinfo that we can use to determine the status of BootGuard (ie: whether or not it presents a threat to us upon flashing a mod). Before we can use this tool, however, we need to figure out which version of it to use (there are .many.).

Please download and launch HWiNFO64 (https://www.hwinfo.com/download/). Uncheck "Sensors only" and "Summary only" and click "Run". One of the two windows that pops up will have a "Save Report" button near the top. Click that button and upload that report here.

Hello

I have a similar machine to yours, G712LV. There is a way to undervolt it via RU.EXE + RU.EFI but you have to it every time. I was on BIOS v308 and on that it was saved but overnight 2 days back my BIOS updated to 314 and now you have to do it every single time to undervolt via ThrottleStop. It will stay for that boot but when you reboot/shutdown, you will lose the undervolting capability and will have to it all over again.

Hi~bs_321
If you only need to do cpu undervolt in this model ,i will recommend
you to adjust "Core Voltage Offset" under Advanced tab => Voltage Configuration in the bios , it's safe to do undervolt on asus intel 10th gen laptop.

I know it's has -80mv restriction ,if you're interesting with it ,i can do a mod for you to break -80mv and more ,i feel the safe undervolt range is in -100mv~-140mv.

yes please please thats all I need. There is this overclocking lock I can disable but it resets after every reboot. On earlier BIOS my sweet spot was -0.120 and it was perfect.
If you break the overclocking lock, then you can do it via throttlestop straight from windows. I dont know why it keeps resetting now after every reboot/shut down.

0x28BBA Setting: Overclocking Lock, Variable: 0xDA {05 91 6E 04 6F 04 D1 01 11 00 DA 00 10 10 00 01 00}
0x28BCB Option: Disabled, Value: 0x0 {09 07 04 00 00 00 00}
0x28BD2 Option: Enabled, Value: 0x1 {09 07 03 00 30 00 01}

I am able to disable the lock so it works for that current boot but when I shut down or reboot I have to do it all over again

You're mistook ,i don't mean to break the "overclocking lock" , please enter to bios then go into Advanced => Voltage Configuration ,then you can see "Core Voltage Offset" ,you can adjust its value to do cpu undervolt , but this option has restriction for -80mv ,i can break it.

First make a bios dump with this tool then attach ,i'll check it and edit a mod for you. (run dump.bat as administrator)
