Clevo W2xxHNx/W2xxHPx series Modded & Stock BIOS [Mods]

Recommended Posts

Clevo W2xxHNx/W2xxHPx series Modded & Stock BIOS

 

Note: This thread is no longer updated. You can find the latest info HERE.

 

Notice: Make sure you have downloaded the correct Mod for your specific model and that the laptop's or a UPS battery backup is present during the update process.

 

Disclaimer: I do not hold any responsibility for any problems that may occur by using the mods in a wrong way. Remember that you flash these at your own risk. I have personally tested the W25xHNx mod. Since the laptops mentioned here are of the same series and thus almost identical, you shouldn't face any problems with the rest of them. The same changes were made to all models after ensuring that their stock counterparts are identical to the tested W25xHNx laptop.

 

Note: All mods contain both the Modded and Stock BIOS image files so that you can go back in case you want to. Use Mod.bat or Stock.bat at a DOS environment respectively. Check the Flashing Guide below for detailed instructions.

      Evening, I own a Clevo P751DM2-G with a 7700k and for a while now i've been having issues with Intel's Extreme Tuning Utility. Everytime I run the program it states that there is a newer version on the Microsoft store and then continues to load. However once loaded it doesn't show the package temp, max core feq, core count or and of the other overclocking features. I've checked the Microsoft store and the Intel website and the version I have is the latest and the utility isn't even on the Microsoft store to download.
       
      Any advice would be great.

      Hi everyone,
      Does anyone know how to make a modded bios with maxwell bio tweaker?
      My problem is, that I want the basic clocks for my system, but just want to be able to verclock past the 135MHz limit.
      So I don't want a permanent OC.
       
      My specs:
      Medion Erazer x7841
      GTX 970m 3GB
       
      Thank's in advance!

      It's locked & hidden by default, but I've got an i7 8700k & I'd like to utilise the intel 'quick sync'/hardware acceleration in Adobe encoding in order to speed up rendering. You don't need to have a display connected to it for it to work (i believe), but it's really fustrating how it is locked out, as it means I'm missing out on quite a useful time saving feature.
       
      Is there any way to activate or mod this?
       
      Thanks!

      Flashing Overview:
       
      - Go to the device manager -> 'Display Adapters' -> chooser your GPU, right click on it and choose disable
       
      - Flash the VBIOS with mnvflash, a modified version of nvflash (see attachments). Below are detailed instructions for nvflash in case you aren't familiar with it.
      - After the flashing is done: Enable the GPU once again in the device manager.
      - Reboot
       
      Detailed Instructions:
       
      As soon as you see the command line you're ready to go, write
      dir and hit enter to display all the files on the USB drive.
       
      Display all Nvidia adapters in the system:
      nvflash -a  
      or alternatively the longer version of the command:
      nvflash --list This command will return you a list with all Nvidia adapters present in your system.
       
      Here's an example output of this command run on my M15x with a 680m in it:
      NVIDIA Firmware Update Utility (Version 5.117) NVIDIA display adapters present in system: <0> N13E-GTX (10DE,11A0,1028,02A2) H:--:NRM B:02,PCI,D:00,F:00 The number in the <> brackets is the index of the corresponding device. SLI users will have more than one entry and flash each card separately.
       
      Backup your current VBIOS:
      Never forget to keep a backup of your original VBIOS before you flash anything non-stock. Use this command to save a copy of the firmware to your USB drive:
      nvflash -b filename.rom or with
      nvflash --save filename.rom  
      Flash the VBIOS to your card(s):
      For a single card it's really straight forward, you don't need to worry about the adapter indices. Just use this command:
      nvflash -6 vbiosname.rom -6 will allow you to override mismatches of the PCI subsystem ID. In case of a mismatch you'll need to confirm the flash with 'y'. NOTE: Users with a non-US keyboard might need to press 'z' or similar, because the 'y' isn't at the same location for all keyboard layouts.
       
      SLI users will need to flash each card separately. The concept stays the same, but you will need to use the corresponding adapter index to flash a card. How to figure out the adapter nr. is described above.
      Flashing goes like this:
      nvflash -i[index] -6 vbios.rom [index] represents a number, namely the index you found with the 'nvflash -a' command. So a command example to flash a card which has index 0 is: 'nvflash -i0 -6 vbios.rom'

      In case you want to buy me a beer
       
      Thanks and cheers!
