Sentarshi Posted March 27, 2022 Share Posted March 27, 2022 Hello everyone I just installed GTX860m on my R3 and faced with several issues so I want to share my experience hopefully it will help others. Part 0 - Preparation All these things you need to prepare BEFORE you will do Anything with your laptop. Modified Nvidia Driver for your graphics card - guide The following IDT drivers Packages - R298411 and R289922 Your new MXM card If you have 120Hz panel - your old MXM card will be also needed (THERE IS NO WAY TO MAKE IT WORK WITHOUT ANOTHER MXM CARD IN CASE OF 120Hz Panel - Because your Intel HD graphics is not available!!!) I STRONGLY RECOMMEND do all these actions on a fresh installed system! All your usual drivers for the laptop should be also downloaded first. All these actions require A12 modded bios for our laptop in attachment Part -1 Bios: Flash Bios from the link above and set the following option there: Sata mode - AHCI Intel HD Audio - Disabled Part - 2 Install your NEW Mxm card Install the fresh system THEN install the drivers by the following order: order Until Step 9 ONLY Don't forget that you need to install Modified Nvidia driver after Turning off Windows Driver signature verification - (How to) Part 3 Making Intel HD Audio great again To install IDT audio drivers you need to do the following: Switch your NEW mxm card to your OLD one TURN ON Intel HD Audio in Bios Boot the system Then follow the steps: Install R298411 IDT Audio Driver Open R289922 install to extract files, but do not install, Cancel ! Go to C:\dell\drivers\V05PT\OEM\Dell Copy IDTNGUI.startup to C:\Program Files\IDT\OEM Go to C:\Program Files\IDT\WDM Run IDTNGUI.exe Advanced Enable Power Management... done Then turn off your laptop and switch the cards again. Continue drivers install. You are all set! Please note: There are many guides where you need to clear CMOS switch cards and wait and so on so on they all sounds like magic - and doesn't work for me - the main issue is Intel Power management system which causes conflict between the Card and HD Audio. I really hope this guide will help someone Alienware_M17x_R3_BIOS_A12_[unlocked]_&_'SATA_fix'.zip 1 Link to comment Share on other sites More sharing options...
